Information Size Measurement :
A Computer is an accurate machine or electronic device based on
a microprocessor, a small semiconductor chip that performs the operation
of a Central Processing Unit(CPU). A computer accepts input, processes data
, stores and produces output according to a series of stored instruction.

Computer System Components
1. Motherboard
was the core of the system which the microprocessor houses. The motherboard is a circuit board that
controls all the devices(hardware) in a computer.
the microprocessor will serves as the brain or the main engine of the computer.
The processor has the ability to processed data that was requested by the user.
fig.2 motherboard
2. Memory
A small circuit board built into the motherboard which contains data that processor processed at a given
time. This serves as a primary storage of the data.

memory chip
Memory has two types these are:
1.RAM(Random Access Memory)
a type of computer memory chip that allows instructions and data to be stored, changed and retrieve by the user.
2.ROM(Read Only Memory)
this will allow a readout capability only.
3. Hard Disk Drive
This serves as secondary storage device , used for storing billions of character of text according to its capacity. Mostly it has a capacity of about 80 Gb(Gigabytes).
