Neural Networks

computer network

 In information technology, a computer network, also called a data network, is a series of points, or nodes, interconnected by communication paths for the purpose of transmitting, receiving and exchanging data, voice and video traffic.

Data and Information

Most people believe that the terms "data" and "information" are interchangeable and mean the same thing. However, there is a distinct difference between the two words. Data can be any character, text, words, number, pictures, sound, or video and, if not put into context, means little or nothing to a human. However, information is useful and usually formatted in a manner that allows it to be understood by a human.

Computers typically read data, but it is not necessarily something that a computer actually understands. Through the use of formulas, programming scripts, or software applications, a computer can turn data into information that a human can understand.

Types of Networks
There are several different types of computer networks. Computer networks can be characterized by their size as well as their purpose.
The size of a network can be expressed by the geographic area they occupy and the number of computers that are part of the network. Networks can cover anything from a handful of devices within a single room to millions of devices spread across the entire globe.
Some of the different networks based on size are:
1- Personal area network, or PAN
2- Local area network, or LAN
3- Metropolitan area network, or MAN
4- Wide area network, or WAN

The Basic Computer Network Components

 Computer networking has become much easier over the years, and it is now possible to set up your own computer network in your home with just a little bit of help. There are multiple components that go into computer networks, but not all of these are needed in every type of network. An understanding of the various components that are available can help you design the right network for your home or business .
