Requirement of Binary System

What if we use decimal number system?

• It is technically not possible to design devices that could represent numbers using the decimal system which we are familiar with.
• This would require components that could be set to ten different states to represent 0-9 which is practically impossible.

Why binary number system is required for the systems?

• All the digital electronics systems are based on two state devices that can be set to either on or off. Example: Transistors, Capacitors etc...
• All the signals are in the form of voltage representing either high (1 ) or low ( 0 ).
• A two state device can only represent two digits.
• Therefore binary system which has only two digits is used.
• A computer system is a two state machine made whose processor and memory is made up of transistors and capacitors which can either turn on or off.
• All the text and graphics are converted to binary system.
