  • A computer is an electronic device which performs "Arithmetical and logical operation.
  • A computer understood binary digit that is 0 and 1.
Computer is an electronic device which accepts  data form user through input device and process the data with the help of processor after processing we desired output form.

A computer also refereed as data processor because It can store the data, Process the data, and Retrieve data whenever desired.

Functions Of Computer

Any digital computer carried out difference function :-    1. Takes data from user through input device.(Input unit)          2. Process the data through processing unit (Processing unit)     3. Store the data through storing device (memory unit)      4. Get desired output through (Output unit)         5.  Control all over four operation (Control unit) So we can say that computer functioned depend on their essential devices, these device are                         1. Input unit                                    2. Processing unit + Control unit ( CPU)                       3. Memory unit                       ...

Types Of Computer Network

There are so many different types of computer networks in existence; it can be hard to understand the differences between them, particularly the ones with very similar-sounding names. This lesson explains the structures and functions of some of the most popular computer networks. 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: Personal area network, or PAN Local area network, or LAN Metropolitan area network, or MAN Wide area network, or WAN In terms of purpose, many networks can be considered general purpose, which means they are used f...
