COMPUTER

 HISTORY OF COMPUTER:

While the concept of computing has roots in ancient devices like the abacus 'modern computers emerged in the mid-20th century with the invention of the transistor and integrated circuits.

Early computer used vacuum tubes,which were later replaced by transistor and more powerful machines.

What is a computre?

A computer is an electronic device that processes data based on instruction,transforming raw input into useful information.

A computer is a propgrammable device that can perform a wide rande of tasks,from basic calculations to complex simulations.

It takes input(data or instructions),processes it according to a program, and outputs the result.

Computer store data and instruction in memory for later use.

KEY COMPONENTS:

HARDWARE:

The physical components of a computer,including the CPU (Central Processing Unit) memory storage device,input/output device(keyboard,monitor,mouse).

SOFTWARE:

The instruction that tell the hardware what to do.This includes the operating system and application software.

HOW ITS WORK;

1.Input: Data or instructions are entered into the computer through input devices.

2.Processing: The CPU executes the instruction and perform calculation or operating on the data.

3.Storage: Data and instruction can be stored in memory.

4.Output: The processed data is presented to the user through output device.
