Introduction-What is Computer<\/strong><\/h4>\n\n\n\n

What is Computer ?<\/h2>\n\n\n\n

The simplest definition of computer is :<\/p>\n\n\n\n

Computer is an computational device.<\/p>\n\n\n\n

A computer is a programmable machine designed to automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem. An important class of computer operations on some computing platforms is the accepting of input from human operators and the output of results formatted for human consumption. The interface between the computer and the human operator is known as the user interface.<\/p>\n\n\n\n

\u2014 Wikipedia<\/p>\n\n\n\n

A computer is a programmable machine. The two principal characteristics of a computer are:
It responds to a specific set of instructions in a well-defined manner.<\/p>\n\n\n\n

It can execute a prerecorded list of instructions (a program).
\u2014 Webopedia<\/p>\n\n\n\n

Computer<\/strong>
Also called processor. an electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations. Compare analog computer, digital computer.<\/p>\n\n\n\n

Computer is an electronic device, which is used for computing and processing the data. The word computer is derived from compute; meaning to calculate, thus it is a machine, which can perform arithmetical operations at a higher speed.<\/p>\n\n\n\n

Characteristics of computer<\/strong><\/p>\n\n\n\n

Speed<\/strong> – Computer can perform tasks in seconds and speed is measured in nanoseconds.<\/p>\n\n\n\n

Consistency<\/strong> – Computer can work without getting tired and with same speed and accuracy.<\/p>\n\n\n\n

Versatility<\/strong> – A computer can perform various types of jobs by multitasking.<\/p>\n\n\n\n

Remembrance<\/strong> power<\/strong> – A computer can retain each and every information for a long period.<\/p>\n\n\n\n

Malfunction<\/strong> – Just like any machine, it is subject to occasional breakdown or malfunction.<\/p>\n\n\n\n

Wrong<\/strong> output<\/strong> – It cannot correct wrong instructions so; wrong input results in wrong output.<\/p>\n\n\n\n

No<\/strong> feelings<\/strong> – Computer is a machine hence, it is free from emotional and sentimental feelings.<\/p>\n\n\n\n

Classification of Computers<\/strong><\/p>\n\n\n\n

Super<\/strong> Computer<\/strong> – Most powerful computer to solve complex problems by parallel processing.<\/p>\n\n\n\n

Mainframe<\/strong> Computer<\/strong> \u2013 It serves frequent access of many computers (100+) like HP 9000.<\/p>\n\n\n\n

Personal<\/strong> Computer<\/strong> – It is most popular as small in size and uses CPU from Intel or AMD.<\/p>\n\n\n\n
