So what is a computer network? From the beginning, this term may seem threatening, but you may have met her or even used it at home or at work. New computer networks should simply indicate that a network is a system in which two or more computers are connected to each other. This is so that people can share things, for example, information or computer hardware, such as a printer.
Now there are several things you need to create a computer network. The simplest system consists of a protocol, network cards or network cards, cables, and a hub.
Protocol is a set of rules that computers must follow to "speak the same language". For example, http is a protocol. If you want to access your website using http, the website you want to access must work on the same protocol, otherwise you will not be able to read the site.
Network cards are cards that are on the back or side of the computer. This allows computers to communicate with each other. The cable is simply a wire that connects computers and the brain is a device that regulates traffic, such as information that a computer sends to another.
Now this is a list of elements in a standard network. You need another device if you want to use a wireless network.
How does the computer network work? For example, suppose you send information from your desktop computer to your father's computer. The computer's NIC sends the cable through the hub. The brain then transfers the data to your father's computer. If each unit uses the same protocol, the data will be accepted by your father's computer and will be able to open the file you are sending.
Offers two types of network: LAN or LAN, WAN or broadband.
LAN is a very easy-to-use network where all connected units are located in one place. There are two types of LAN, peer to peer and client server. A peer to peer network where two or more computers are directly connected to each other. For example, computer 1 is connected to computer 2, computer 2 is connected to computer 3, and so on. Computers depend on each other, so if a unit has problems, then the others simply can not connect to each other. The client server type is where each computer is connected to a main unit. This is more convenient because if a computer has problems, the rest will have no effect. You will still be able to exchange data.
Example of a WAN in the Internet. As you can see, this is a very large network that allows millions of users to connect.
More and more people are looking for a computer network, even at home. It Provides Greater Comfort for People and Enables Everyday Life More Effectively
