Hardware and Operating Systems
Computer Language and Function
When we communicate or memorise a sentence or make calculations, we use a lot of different symbols, sounds and images.
Computers only use the numbers 0 and 1.
This is known as the binary system.
The smallest unit of information that we can store on a computer (0 or 1) is called a bit (b), which is an abbreviation for binary
digit.
Eight bits together form a byte (B). Different multiples of a byte are used to store information.
Notice that to increase the level, you have to multiply the units on the left by 1 024 and the units on the right by 1 000.
ASCII
We give a code to each of the letters of the alphabet,
and to the characters computers use, so that we canstore them. These codes consist of the figures '1' and '0'.
ASCII (the American Standard Code for Information
Interchange) uses 7 bits to store up to 128 different
characters.
Extended ASCII
Using extended 8-bit ASCII to represent characters
allows for 256 different characters, including special symbols and international characters.
Computer Functions
We use the name hardware for the physical components of the computer system that we use and those we can touch and
move, like the mouse and the keyboard.
Software or programs refer to the data and the instructions we use to manage that data.
Computers carry out four different functions:
Computers process and store information in the form of text, numbers, photographs, music and so on.
When we use a computer to do calculations, change the font of a text or change the colours in a picture, we are processing
information.

carries out an operation. A modern 4 GHz
microprocessor receives 4 billion impulses every
second.
