what is computor soft ware

A computer is a physical collection of bits that you can touch. The screen, main system box, keyboard and mouse etc. But inside is this mystical is a stuff called software. Before we look at it, let's have a look inside the computer.

At its simplest a computer is made up of the following parts, most of them are in the system unit.

• A Central Processing Unit (also called a CPU)
• Read-Only Memory (ROM) that holds Permanently Stored instructions.
• Random Access Memory (RAM) to hold software and data.
• Input and Output Devices such as Screen, Keyboard, Mouse and Printer.
• A permanent storage device such as a hard disk,or floppy or flash drive

 

But what exactly is software?

It is the combination of Instructions and Data, known as machine code that forms the building blocks of applications such as Word Processor, Computer Game or Spreadsheet.

This machine code lives in the memory of the computer as billions of little on off switches. Exactly the same as a number in a calculator- courtesy ask.com
