INFORMATION AND COMUNICATION TECHNOLOGY GYAMFI SERIES
Storage stage; at this stage the information is save for future use or retrieval. Devices used for
storing information are called storage devices. Example of storage device are pen drive, hard disk,
floppy disk or
diskette, CD/DVD and Random Access Memory (RAM)
Communication; the communication function of the computer makes it possible for data to be shared
between two or more points/ location.

COMPUTERS CAN BE CLASSIFIED ACCORDING TO:
There are only three main classifications of a computer. Namely;
1. Classification by Type or data handling
2. Classification by Purpose
3. Classification by Capacity or size

CLASSIFICATION BY TYPE/DATA HANDLING
1. Analog Computers, these computers are so named because
they perform computations by setting up physical situations
that are analogous to mathematical situations. Examples are:
thermometer, Voltmetres and speadometre of cars.

2. Digital computer. They are basically counting
device. It solves problems by counting precisely:
adding, subtracting, multiplying, dividing and
comparing. E.g laptops and palmtop computers

3. Hybrid computers: it combines analog and digital capabilities in the same
computer system.
E.g calculator and Automated Teller Machine (ATM)
