We often encounter the word computer networks in our daily lives, but some of us try to understand.
This is one basic thing that every computer user is supposed to know.
By the end of this survey of computer network technologies, we hope you learn something through a computer network.
Network as the word suggests, is a set of things that are interconnected with each other.
Likewise, when we say computer networks, the brain draws the picture of many computers linked together.
If you have understood the last line, you have successfully grasped the concept of computer-networks.
Now we are moving further and try to say more about the computer networks.
r
The common types of computer-networks are explained below.
LAN (Local Area Network) If we use the word local, we use it in relation to some reference.
In the same way, when we say Local Area Network, it is said with respect to some frame of reference.
This type of network is generally used over short distances, such as in offices, universities, organizations and hospitals.
r
LAN has wide range applications such as DATA Sharing inside an organization.
All members of the department can share expensive resources such as a hard disk or a laser printer over LAN.
One person or a single organization usually owns Local Area Network, thus making it easy to handle.
WAN (Wide Area Network) As we move in a systematic way, we just finished reading over Local Area Network.
Now for a moment, consider your home, when we say that the two computers in your home are interconnected, it is done by local area network, but if we say that the computer in your home is connected with the computer in London or any far off place, we would call it Wide Area Networking or WAN.
One can also say, WAN LAN set of numbers.
A device called router connects LAN to WAN.
The Internet is the greatest use of the WAN.
We are accessing data via internet from all over the world.
We share the things that you send an e-mail, we are obliged to voice conferencing, video conferencing over a WAN.
Like LAN, a sole body or single organization do not own WAN's.
It usually has a collective title.
r
Above were the two basic and major types of computer networks; however, there are some small types of networks as well.
We want a small review on them.
Wireless Local Area Network
LAN based on Wi-Fi wireless network.
This technology is usually in restaurants, universities, hospitals and organizations are used to provide free Wi-Fi.
A device called wireless modem is used to access Wi-Fi Internet.
Many of the latest laptops and mobile phones have this built-in Wi-Fi.
r
Metropolitan Area Network
This is a type of network that is used in cities.
Single agency or institution, the large companies generally use these.
Above was an overview to computer network technologies and their usage.
By the end of this article, we hope you learned something.
In this article we have not touched the technical aspect of computers networks.
Symmetries of Computer networks are complex to explain.
It requires a lot of hardware and software knowledge.
