Guidance to Teaching English

Joining TEFL class is really fun! For me personally, I have always wanted to practice my English anytime, but not many people in Costa Rica like to speak English, and this is burdening me a lot. I am just lucky that TEFL Costa Rica class has entertained me well with a lot of English practices and discussions where I could express myself in English. Exercises both written and spoken really help me increase my courage in speaking English before people, as well as the target of this training which is to get us all to be able to teach English orally. Since my graduation from college, I have been teaching English in several independent schools and private courses. It is fun for me because I get to see many different people and I personally like to teach English.

As my plan to go back hometown to Milan, Italy, I have proposed to get temporary jobs as long as I stay there. Some application has already been couriered to my relatives in Milan just to save the time. They also have promised me to be able to teach English in Italy. I only need my relatives there to support me with some guidance to teaching there – especially English. I am just a little bit hesitated to find out what the Italian students and how teacher-learning process there would be like. Different countries of course have different cultures, and they really impact on lifestyles and association in those countries. And this is what I am really in need of perfect preparation.

Yet everything definitely depends on the test result of my TEFL test I will face within this week. I am not actually trembled, in fact I am sure that I am already well prepared; however, who is not shaken facing a kind of test? The certificate will surely give me better points on my English teaching experience; apparently, this certificate would be the first thing to consider before referring to other things on my job application. And, as a matter of fact, the certificate gained after I pass TEFL test could be best reference when I try to get jobs overseas besides an English teacher. There are companies require their employees as well as new job applicants to have TEFL certificate. And I am glad that I will get one before getting a job overseas, back to my home town.

What is it that Makes Laptops so Popular?

Nowadays many people have laptops for their life. Both young and old people use a laptops. What cause laptops so popular?? Let me tell you the reason why laptop so popular.

Laptops have taken the larger share of the computer market these days and are still gaining popularity. Whether for business or personal use, the convenience of these machines has convinced people to purchase higher-priced laptops over the cheaper desktops. So the question should be: is convenience really enough to justify an added price?

The affordability of the computer in question isn't something that should be taken lightly, given the current economic crisis. So if the only feature that recommends laptops over desktops is portability, then shouldn't you choose the one that won't break the budget?

Desktops have a number of beneficial features. For example, they are designed to be extremely modular which means you can set them up to meet your exact needs. This way, whether you are processing lots of videos or just want to play the high-end games, you can easily add the RAM or graphics cards that you need. You can also limit yourself to a very affordable computer if you just want to use it for social networking or Web browsing.

Laptops are a little more difficult to upgrade and set up to your exact specifications. They can also have keyboards and touchpads that are difficult to use. So why are laptops becoming so popular? Is it really all because of their smaller size? Is that really enough to justify the extra expense?

In a fast-paced business environment, you really can't underestimate the inherent value of a portable machine. Whatever you will use it for, these computers can help you stay in contact with others while still doing your work on the road, whether it is social networking or accessing important business programs and documents while on the go.

Laptops continue to develop and they have advanced to the point that you can now get computers that are sleek and light and can easily be transported from place to place. Despite their small size, they often have all the processing power and graphical capabilities of their larger cousins.

It should also be said that while laptops have traditionally been more expensive than desktop computers, those prices have been steadily declining. As technology improves, manufacturers can find a lot of ways to make their laptops more affordable.

The economy is making things tough for a lot of people, but laptops continue to grow in popularity because the portability means they can be productive no matter where they go. And if they can maintain those standards of productivity, they have a better chance of getting out of tough times. That means laptops are really more of a wise investment.

Desktop, Laptop or Netbook Computer

Nowadays development of technology is rapidly. Many product of technology development such as desktop, laptop, notebook , and more

If you are undecided whether to buy a desktop or a laptop computer, then you may want to read on in order to find the advantages and disadvantages of each. One option will probably work best for you, so be sure that you make the best choice.

When home computers were first brought on the market all computers were desktop models. Today, all these computers have their CPU in a tower, which gives them many advantages. Even though they have been available for many years, there are some advantages to desktop computers.

The larger computers tend to cost less than laptop computers. Although the prices have dropped for laptops, the other machines remain the better buy. In addition, the machine that utilizes the tower tends to have more options.

The older style computers are also easier to upgrade. While laptops can be upgraded, it is only on a limited basis and more expensive than upgrading a computer that has most of its components located in a tower.

One of the drawbacks of computers that have a separate keyboard, monitor, mouse and CPU is that they are not portable. Additionally, they are less energy efficient and are more difficult to set up. These computers do not retain resale value as well aslaptop computers do.

Laptop computers, which are also called notebook computers are smaller than the other models. They offer portability and use less energy.

Portability is one of the greatest advantages of laptop computers. They can be used almost anywhere that you are protected from the elements. Internet access is easy in any wi-fi hotspot. Setting up a wi-fi router in your home allows you to access the internet without connecting any wires.Laptop computers have a built in battery that is charged from home current or can be charged from an automobile.

Laptops are an excellent choice for persons with limited space. They are great for college students living in dorm rooms as well as anyone in a home where there is not room for a computer workstation to be set up. The computer can be set up and taken down in only a few minutes. The only cord requiring attachment is the power cord. When done for the day, the computer can be closed and stored for the day.

A laptop will cost more than a tower type home computer with the same performance. Additionally, it is easier for someone to steal your laptop. Because of the small space, it is easy heat to build up in the laptop and this limits upgrades. You will also find that repairs are more expensive.

Netbook computers are small notebooks. They have a small keyboard and may have a small CPU. They do not have a CD or DVD drive.

Lithium Batteries

Lithium batteries is one example about growing technology. Actually what is Lithium batteries?? What is the different with alkalne battery??

Lithium batteries are very popular now due to it’s competing technology and has certainly reduced the good old alkaline battery. Lithium has the highest specific energy of all and is much lighter than other types of rechargeable batteries of the same size. They have a longer life than the other batteries, to say it last more than 3 times the predicted use time which means a better value for money. Sure, they are slightly costly than the other alkaline counterparts, but this price comes with an advantage of having the appliance last for much, much longer than usual.

Being of high energy density, it makes an excellent choice to ensure that an appliance will run for a very long time without worry of substituting or constantly charging the battery. These batteries have found their applications in many long life, low drain critical devices for both consumers and the medical industries. A good example is that the medical industry has seen great success in switching their pace makers over to using lithium batteries. Small lithium batteries is best because it is able to power effectively devices like PDA's, watches, calculators, small computers and remotes quite effectively over a long period of time. Lithium batteries are also great for quick drain high energy devices like digital cameras, as they can maintain a higher voltage for a longer period of time. Their recharge times are also mainly shorter than alkaline rechargeable batteries.

Many major manufacturers are turning their attention to improving the lithium technology and extend the life of the battery to longer periods and shorter recharge times. As appliances get more and more complicated as the years go by, these great lithium batteries need to adapt as well. As they are safe, environment-friendly, can endure thousands of cycles of charge/discharge and will keep lowering their manufacturing prices as they become mass-produced. For all that they are the best alternative in the consumer market .

CDMA for Mobile Phones

Today a CDMA technology is growing rapidly. Almost all mobile phones use a CDMA technology. Although there are other technology for mobile phones, CDMA technology not lose prestige. Their can growth for time to time.

The CDMA technology enables you to increase over narrowband multiple access wireless technologies. The real cell coverage areas are highly irregular at times. The base stations and mobile stations communicate by a negotiation upon call origination. Then the movement of mobile is detected and then another base station takes up the service and is then passed on to another.

This technology has a high capacity as it uses noise-like waves. Multiple users utilize each CDMA carrier frequency which makes frequency reuse a universal phenomenon. Initially, the concept of CDMA was discarded as it was taken to be unworkable in mobile radio environment due to the near-far problem, because of the spread spectrum. Te transmitters here can be controlled such that the received powers are all equal. This makes the benefits of spreading realized easily.

The voice coding used in CDMA is standardized separately as a service option. The various standards operate in the nominal 9600 bps rate set, generally. As the required transmitting powers of the CDMA mobile phones increase on approaching the capacity pole, mobile coverage tends to run out. This in turn leads to system load resulting in coverage failures associated with the CDMA technology. This somehow is troublesome for the CDMA mobile phone users and is taken into consideration.

CDMA phones differ from the GSM phones in the sense that, it enables you to make use of only one type of connection and leaves you with no other option of changing your network service provider. This at times creates a problem for the users who change their mobile phones quite frequently. Every time they change their CDMA phones, they have to change their phone numbers too. This makes it difficult for the business men and other people who use their phones to a greater extent.

CDMA users can make use of web browsing, m-commerce, MMS, streaming videos, games and e-mail, as this technology provides them with various applications and data services too. It also delivers high speed data and supports multiple application platforms, including java. It also provides with traffic updates, navigation and tracking. This enables you to locate the nearest or your most favourite restaurant, shop, theatre and what not. It also offers 'push to talk' facilities that doesn't require dial-up but just needs pushing a button and simply beginning to speak, that is offering two way voice and data sessions. It also offers graphics, pictures, video or even music attachment abilities to text messages, sent to mobile devices as well as computers.

CDMA mobile users have national as well as international roaming services enabled, which enables you to talk or even share documents on the go.

Verizon Cell Phones: The New Generation

A technology will never stop to growing. Recently issued a technology which known as 4G.

4G, which is also known as "fourth generation", deals with the replacement of 3G (third generation) in the wireless industry including Verizon Cell Phones.

It is the next generation in line for cell phones like Verizon phones and related devices. Right now, everything is not set in place yet, so the term is used for marketing purposes at the moment. The communications industry has not yet come to a conclusion as to the part that 4G will actually play in the industry.

When it is set in place, this level of communication will be more powerful than 3G. That means all phones like Verizon cell phones will be replaced by what is considered to be the next evolution in the wireless industry. In addition to that, the security measures will be improved and enhanced for 4G. Where 3G was responsible for data efficiency, 4G will work to go beyond what 3G did. It plans are to enhance smoother measures in transmissions within different networks.

There are already a few cell phone providers, including Verizon Phones, that have stepped into the next generation. They are still testing and looking to expand soon. 4G will be used to access the internet on your computer and supporting communications for cell phones. This will be what the majority of this system will deal with.

Home broadband connections will be available for those who will not have 4G access or the access is not strong enough to use. Using these connections will eliminate the cabling process. People will be able to use the internet while they are on the go without having to set up in wireless areas such as airports, and coffee shops.

The growth of 4G is projected to surpass that of 3G. One of the reasons will be due to the cost. The subscriber growth will be quicker than what it was when 3G emerged. Even though 4G will cost more in the beginning, it will not require as many components as its current predecessor did. With fewer components, there will be a decrease in cost for the consumer.

It has been predicted that within four years 4G will surpass the 100 million mark within four years with subscribers like those of Verizon Cell Phones. That would beat the 3G network by two years; it took six years to reach that point.

So, will 4G be better than 3G? From the looks of it, 4G is poised to be on the cutting edge of technology that will surpass the previous generations of technology

No More Problems with Algebra

That is true! I have no more problems with algebra since I found the best algebra tutor. Well, you will think the tutor could be a sort of old professor with hairless head and thick eyeglasses, terrible performance (just like a professor could ever be), so strict and everything a student does not want a tutor to be. It is absolutely wrong and far different from what you are imagining. Ok, let me tell you who this tutor actually is.

This tutor, or I prefer say a best friend indeed, is an online algebra tutor. You might think that this is another boring thing to do; a waste of time and getting information that you don’t think you need. Of course it is not that such; the online tutoring service is one of the best math online services all around the network in the world and surely the most preferable service I have selected. From the pre algebra homework help to the advance level such as college algebra could be found here and I only need to consult to the online operator or just send them an email.

Registering is what you need to do to make things easier, and they will consider that we are serious to ask their assistance as well as to get algebra homework help. In addition, being a member of this online service will give us more advantages. They will provide us extra tutorial and even articles to refer to when we are having algebra problems. We will also be included into any forums that most of the attendants are good at solving algebra problems; we will be introduced to them and will get extra helps.

Systematically, we attend a forum and post our problems in algebra. Members of the forum who recognize the problem solution, or I guess all members could do this, will reply our posts by giving us clues, ways to solve, or even just final answers. For them who is not in the mood to find the way how to do algebra problems, gaining final answers is just fine. But for me, I don’t really like that sort; I prefer getting the solution in short or long explanation. And most of those members could do that.

When members could not find the best solution on difficult problems such as college algebra problems, the provider will expropriate the problems and will notice the problem owner to contact them personally.

Shopping for a Pc

Do you have a plan for shooping a pc?? Let me tell you about a great ways or step when you want to shooping a pc.

It is not honest, however shopping for a laptop is simply plain easier for some than it's for others. People who've purchased and used a laptop within the past already have an idea of what they have in a new computer. But those that are new to the computer world might wander away within the myriad of choices available.

The short answer to "What ought to I purchase?" is "The best." Of course that answer is extremely subjective as a result of "the most effective" to 1 person is definitely totally different to another. Our definition of "the most effective" is that the fastest and the most important, but even that leaves the computer newbie confused. Here's a fast rundown of what the computer novice ought to do and why.

1. Buy a laptop that has basic peripherals. Each computer will be counteracted into four major parts: CPU unit, monitor, keyboard, and mouse. For the novice, it's best to shop for a pc that has all of those parts included so that when it's taken home, assembling the computer is a simple matter of plugging things in where they belong. Save the individual purchases of these parts for people who have additional experience.

2. Decide what you will use the pc for. If you wish to use your computer for cruising the internet, sending email, or performing simple word-processing or spreadsheet tasks, a computer with the basic elements that we just described ought to suffice. If you would like to use a laptop to assist with a career in multimedia but, you're going to wish to decorate your system with a scanner, printer, digital camera, tablet, or digicam for example. If you wish a computer to help with a career in music, you may need a high quality microphone and set of speakers.

3. Create a budget and follow it. How a lot of can you afford to spend on a new pc? Though the prices of computers are decreasing, they'll still produce a hefty expense particularly if you need extra peripherals described above. Additionally, you may want to work in costs for maintenance, servicing, and insuring.

4. Begin comparison looking and look for the "fastest and biggest." By "fastest and largest," we mean the computer with the fastest processor, the fastest modem, the biggest memory, and the most important hard drive capacity. Whether or not you think that that you'll never need the amount of speed or space accessible out there nowadays, it's important to own in the event that you really do want that much within the future. Having such a massive reserve will slow down on costs when the time comes to upgrade for additional than what you may settle for in a pc that offers less.

5. Follow the better-known brands. Venturing off the crushed path with lessor-known brands is again, an journey for those who have additional experience with computers. Although those higher-known brands could be a tad bit more expensive, the computer novice can appreciate the comfort in buying a pc from a business that has a long record of building quality product, which has the funds out there for fulfilling returns, trades, servicing, and warranties.

6. Choose a store. Having an plan of what you want during a pc and what sort of laptop that you want, your solely task left is to pick the place in that you would like to buy it. There are a selection of places offered together with computer store retailers, on-line stores, auction sites, used pc stores, or your friendly neighborhood yard sale. For the pc novice, we tend to advocate buying a laptop from a physical store. In a physical store, you have the chance to determine the computer of interest personally and ask questions. New pc consumers conjointly have access to store warranties, returns, trades, and services.

These suggestions should give the pc newbie a great start in choosing a quality pc for the first time and they apply to either Windows computers or Apple Macintosh computers. Once making these selections and eventually selecting one that matches your desires, you'll be able to then venture into the fascinating world of software - a world that is just as grand as the world of hardware!

LED Flashlights: What Makes Them so Popular?

Whether when your school you get a electro lesson?? If yes, you must have known about LEDs. Can you tell me about what is advantage of LEDs??

Light emitting diodes, or commonly known as LEDs, have been around in all sorts of devices. You have seen them around in traffic lights, watches, remote controls, television sets, etc. Flashlights are a typical example of this - using new technology in old products. If they are becoming so popular what are the advantages of LEDs over traditional bulbs?

Unlike ordinary incandescent bulbs, LEDs are illuminated by the movement of electrons, and do not have a filament that will burn out. As a result, they do not heat up easily, but still last just as long, or even longer, than a standard bulb, making them safe for use in a tent or other enclosed space.

This difference contributes to the main advantage of LEDs:

Efficiency. The traditional process producing light of conventional incandescent bulbs involves heating up the filament until light is given out. This process is highly inefficient, as it generates a lot of unnecessary heat. This heat does not produce any light, and the energy needed to produce that heat also drains your batteries.

LEDs, on the other hand, generate relatively little heat. More of the power from your batteries goes to producing actual light, which means you get to use smaller batteries, or enjoy longer battery life.

The more compact LED is another advantage in that it allows for Led flashlights with smaller form factors. And unlike traditional flashlights, LED flashlights also do not force your eyes to re-adjust to the darkness every time you use them.

LED's also have much better resistance to shock and impact. I've heard several stories about LED flashlights being dropped from six feet or better on to concrete and the LED was unharmed, although some of the flashlight cases didn't survive the experience.

LED torches are simply are simply amazing. Small, lightweight, and powerful to the point of blinding, they are revolutionizing how we use flashlights. If you ever find yourself needing a flashlight that offers you bright light with dependable use, then led flashlight is the best one that you are looking for.

WildBlue and Wireless Routers

Do you know what is WiFi?? And how it works??

WiFi is a wireless Internet that is provided using a wireless router. It uses radio waves, just like your cell phone, television, and even you car stereo. The communication between your computer and your wireless router is a lot like having a two-way-radio. Wireless networks are easy to set up and are very inexpensive.

Here is how it works!

In your computer there is what’s called a “wireless adapter”. Almost any new computer should already come with this installed. Your computer’s wireless adapter can translate any data you may have stored on your computer into a radio signal. Your wireless adapter will then send that radio signal to your wireless router.

Your wireless router will then take that radio signal that your computer’s wireless adapter sent, and decode it. The router sends that information to the Internet using an Ethernet cable.

This cable is colored yellow or gray and looks like a phone cable only bigger. It is plugged into the back of your router and runs to the modem that your Internet service provider, (ISP) supplied you with. The modem is what actually brings the Internet to your home. If you have a cable ISP, they some times will give you a modem that double as a wireless router. They usually add a charge for this on your monthly bill. DSL and Satellite ISP’s do not offer that.

This process can also work in reverse. The wireless router can receive information from the Internet, translate it into a radio signal and send it to the computer's wireless adapter. Giving you Internet on your computer.

How many computers will work with WiFi?

Several. As long as all the computers or laptops have wireless adapters, they can use one router to connect to the Internet. The wireless connection is invisible and fairly reliable. Unfortunately, if too many computers are connected at the same time the users may see some interference or even lose their connections as the bandwidth is limited in this setup.

Bandwidth

To help you try and understand what bandwidth is, think of the Internet as one big highway, and the information you take in as a car on that highway. If you’re the only car on the highway you will travel much more quickly and with a lot more ease. If there are a lot of cars on the highway, traffic can build up and slow everybody down.

In theory your Internet works the same way. If you are the only computer connecting to your wireless router, then all the transferring of information should happen fairly quickly. If there are many computers connecting to your wireless network, the information may reach you much slower.

F.A.P. (Fair Access Policy)

When it comes to cable Internet providers, the amount of streaming or downloading you are allowed to do is virtually endless, their bandwidth/highway is fairly large and can provide you with that luxury. If you have DSL or even the dreaded dial up, your Internet is brought to your home using a phone line and provides a smaller bandwidth range than a cable ISP. This is why you may experience a slower speed or get knocked of the Internet when your ISP is a phone company.

With satellite Internet like WildBlue, they put a F.A.P (Fair Access Policy) in place. What the F.A.P does is limit all their user’s bandwidth to a cretin amount. Think of the highway again. If you put a limit on how many cars can drive on the highway it would reduce the amount of traffic, there for you will be able to keep a certain speed while traveling. F.A.P. allows you to take the information from the Internet at the same speed as everyone else on that service without and interruption or risk of being kicked off. When a satellite ISP puts a bandwidth cap on their Internet usage it is more for your protection then anything else.

Video and Audio Streaming

Your Internet Bandwidth plays a very big role in the amount of streaming video and audio you can get to your computer. When you use streaming programs like Netflix or Hulu, they require your Internet to have a large amount of bandwidth. Think of the highway again, but instead of the car think of the highway the car is driving on as information. Think of your car hauling a movie that you want to stream. If your highway/bandwidth isn’t big enough your car won’t be able to deliver the goods. The same rule applies for downloading as well.

Video and Audio Downloading

Streaming and downloading are very similar in they way they receive the information from your wireless router, but are still very much different. Streaming technology allows you to watch live or on-demand video, without having to store or make a copy of the information to your computer’s hard drive. When using downloading programs like Napster, Kaaza, or even iTunes to download video or music, you are taking the file or information that those programs provide you and making a direct copy of the file to store on your computer for later use.

VoIP (Voice over Internet Protocol)

VoIP, (Voice over Internet Protocol), is the process of taking analog audio signals, like the kind you hear when you talk on the phone, and transferring them into a digital signal. This takes a standard of Internet connection and turns it into a way to make free phone calls.

There is VoIP software available for download for free online; and a lot of VoIP companies like Vonage or Magic Jack are offering minute-rate plans just like a cell phone. These plans are available for as little as $30. VoIP providers add features for free that most normal phone companies will charge you extra for.

VoIP plans usually include:
· 3-way calling
· Call waiting
· Call transfer
· Caller ID
· Return call
· Repeat dial

Although VoIP is less expensive, the network that makes up the Internet is much more complicated and has a greater margin of error, because of this, VoIP is a lot less reliable then your normal phone company.

VoIP is run on wall power. You home phone is runs off of phantom power (unless it is a cordless) that’s provided over the phone line from the phone company. Unlink VoIP, your home phone line will still work even when you home has no power. VoIP will not.

Because VoIP uses your Internet connection, it is vulnerable to all the normal problems that you might run into when having an Internet connection.

· Bandwidth
· Latency (Delays)
· Viruses
· Drop offs

All of these factors can affect your call quality and is why VoIP is not recommended with the use of satellite Internet.

Setting up a Home Network

Do you have a plan to make a home network?? There is essentially two ways of setting up a home network, wired or wireless.

A wired network involves connecting up the computers using cables, and if often referred to as an Ethernet network. An Ethernet network transfers data at high speeds, faster than wireless networks as it is very rare for the connection to be interrupted. Although data transfer speeds of 1 Gbps can be achieved, the average speed is 100 Mbps, and this is why you will often see "10/100" next to Ethernet ports on computers or in product data specs.

A wireless network transfers data via radio waves and is the preferred, and most often convenient, method of setting up a home network. It is especially useful for the use of laptops as it allows the user to roam throughout the house, and even the garden, without having wires trailing behind them. A wireless network is often referred to as a Wi-Fi network, which stands for Wireless Fidelity and is based on the 802.11 wireless standard.

It is also possible to create a home network which combines both wired and wireless technology.

There are distinct advantages and disadvantages as to whether you opt for a wired or wireless network in your home. A wireless network offers you more freedom to move around your house with your laptop and of course without the need to trail wires from each fixed computer. It is also easy to add more computers to the network without having the need to buy more networking equipment. However, where a wired network offers less freedom, it is cheaper to install and potentially faster due to the connection being rarely interrupted. A wireless network also has restricted boundaries, whereas a wired network is only restricted by the length of cables you have.

In order to set up a home network you will need to purchase some specific hardware. Knowing what hardware to buy is often quite daunting due to the amount on the market, and the fact that you do not know exactly what something is and what it does! Essentially the main piece of equipment that you will need is known as an ACCESS POINT. This is the small box with all the flashing lights that allows the connection between the computers in the network to take place. There are several types of Access Point, and although they essentially do the same job, the type you need (and you may need more than one) depends on your computer, internet connection and they type of network you wish to set up.

To make sure that you choose the right Access Point, we have constructed a guide to the various pieces of hardware to ensure you purchase the parts you need to set up your own home network.

Router: The most important piece of hardware on a home network setup. The router is the part which routes the data to the computers on the network. It basically connects all the computers together so that they can share the internet connection and browse it at the same time. The router also acts as a line of defence between the internet and your computer. Most have built-in software to protect your identity and your computer from viruses.

Hub: The device used to connect the computers to the network via Ethernet cabling or via Wi-Fi. Wired hubs come with a number of ports which can transmit data at speeds ranging from 10 Mbps to multi-gigabyte speeds per second. The hub transmits the data it receives, often from the households' main computer, to the other computers that are connected to it. The amount of computers that can be connected to a hub depend on it size. The average hub can connect 4 computers. A larger hub could connect nearer 50. A wireless hub can connect hundreds.

Switch: This is a type of hub that controls the way that multiple devices use the same network so that each can operate at optimal performance. A switch acts as a networks traffic police: rather than transmitting all the packets of data it receives to all ports as a hub does, a switch transmits packets to only the receiving port. Switches are fast replacing hubs as a preferred choice of data management as prices are more in line with hub prices.

NIC (Network Interface Card): A type of PC adapter card that either works without wires (Wi-Fi) or attaches to a network cable to provide two-way communication between the computer and network devices such as a hub or switch. A Network interface card can be installed internally into a desktop PC or slotted into a Type 2 PCMCIA slot on a laptop or PDA.

Combined switch/router: A popular choice of Access Point as it combines both the functionality of a router and switch in one unit.
