Computer
- Computer isn't an acronym, it's a word derived from a word "computer" which means to calculate. So, in simple words you'll say that computer is a device which is used for fast calculation.
- Some people say that COMPUTER stands for Common Operating Machine Purposely Used for Technological and educational Research.
- It's only a myth because first this definition does not make any sense and second when the computer was invented they were just calculating machines which need a lot of space for establishment.
"A computer is a general purpose electronic device that is used to perform arithmetic and logical operations automatically. A computer consists of a central processing unit and a memory."
COMPUTER = Arithmetical Logical Unit (ALU) + Control Unit (CU)
- ALU : Arithmetic Logical Unit is used to hold out arithmetic and logic operation.
- CU : Control unit is used to vary the order of operations in response to stored information.
Arithmetic Logical Unit
