What is computer networks? For the uninitiated, this term may sound intimidating, but you may already have come through it or have even used either at work or at home. For new networks of computers, in a few words, a network refers to a system where two or more computers are connected to each other. This is done so that people can share things like equipment or information of the hardware, such as a printer, for example.
Now there are several things you need to set up a computer network. The most basic system consists of a Protocol, network, cable and a concentrator or NICs interface cards.
A protocol is a set of rules that teams have to follow in order to "speak the same language". For example, http is a protocol. If you want to be able to access a Web site from the computer that operates over http, the Web site accesses also should operate in the same protocol otherwise won ' be able to read the site.
The NICs are cards that are placed at the rear, or part of a team. This enables computers to communicate among themselves. A cable is just a cable that connects together teams and the concentrator is a device that controls the traffic, for example, information that a computer sends to another.
Now it's a list of elements of a standard network. You'll need a different set of devices if you're going to go for wireless networks.
How does a computer network? For example, suppose that you want to send the information from your desktop to the team of his father. The NIC in your PC transfer the file across the wire in the Center. The hub, then transfers the data to the team of his father. If each of the units using the same protocol, below, the information is accepted by the team of his father and will be able to open the file that you send.
There are two types of networks: LAN or local area network and WAN or wide area network.
The LAN is a very simple type of network where all the units connected in one place. There are two types of LAN, peer to peer and client-server. A network point to point is where two or more computers are connected to each other directly. For example, team 1 is connected to the computer 2, computer 2 is connected to the team 3 and so on. The teams are dependent on each other, so if a drive experiencing problems, others will simply not be able to connect to each other. The type of client-server is where all computers are connected to the main unit. This is more convenient because if a team has problems, others will not be affected. Still be able to Exchange data.
An example of a WAN network is the internet. As you can see, this is a very large type of the network, allowing millions of users to connect among themselves.
More and more people are looking for computer networks, even in your home. This gives people more comfortable and makes more efficient life day by day
