Computer is an electronic device which can take input from the user and process this input data and if need, store data or information on storage devices and give output on output devices.

Computer contains a number of components for processing the information. The major components are - Hardware & Software.

Softwares are logical components of computer, which can't be seen and touched. Software's are used to run the computer in efficient manner without software; computer is like a vehicle without fuel. These are four major types of software:

A class of device which performs mathematical operations and carries out logical comparisons like a normal human brain is called a computer. Earlier computers were mainly mechanical ones whereas the latest versions are completely electronic devices

Digital computers in particular possess the following prominent characteristics...

A binary number can be readily converted to a decimal number, just by adding their positional values. Let us have a shortcut formula to convert a decimal number to binary. It is called as Division-Remainder technique. The steps to be followed are...

Following steps have to be followed to convert a decimal fraction to binary

We are well conversant with binary numbers. As discussed earlier an electronic/ magnetic device can recognize two distinguishable states, we assign one state to 0 and the other state to be 1. Thus every single binary digit is stored and processed separately by a digital computer.

It is the process of feeding data and instructions to a computer system...
