8. HARDWARE
 Hardware is the physical component of a computer system.
 It refers to the electrical parts and devices that make up a computer.
Generally, hardware is categorized according to the five basic operation it performs:
Input devices :(we use to send data to computer processor/memory)
Processors: (fetch, decode and execute data into information)
Memory: (it holds data/instructions that CPU needs)
Output devices: (display information/results)
Secondary storage devices :(Store data/information for later use)

WHAT ARE INPUT DEVICES?
 Input hardware are used to enter data into a computer by encoding via
keyboard, direct reading through scanners and pointing devices like the mouse.
 Input hardware converts data, e.g.. text, image, drawings into a form that a
computer can understand and use.

memory
 In computing, memory refers to the physical devices used to store programs
(sequences of instructions) or data. i.e. Text, Images, Videos etc.
 Computer memory is the storage space in computer where data is to be
processed and instructions required for processing are stored.
Memory is of three types :-
1. Cache Memory: cache is a smaller, faster memory which stores copies of the
data from frequently used main memory locations (RAM).
2. Primary Memory/Main Memory : divided into two subcategories ROM
and RAM
3. Secondary Memory : where programs and data are kept on a long-term
basis.

processor
The device that interprets and executes instructions.
It is called the brain of the computer
The faster the speed of the processor, the faster the execution of instructions
The procedure that transforms raw data into useful information is called
processing
The processor and the main memory devices are the processing hardware
