Slide 1: Title slide

Your name and position.

Slide 2: Introduction

Computers can be categorized according to the process they used to represent data.

People communicate through speech by combining words into sentences,

Human speech is analog because it uses continuous (wave form) signals that vary in strength

and quality.

Most computers are digital.

Slide 3: Analog computers

Analog Computer is a computing device that uses continuously changing values to represent

information

23

It generally deals with physical variables such as temperature, weight, voltage, pressure, speed.

etc.

Examples of Analog computers include: Thermometers, Weighing scale, Voltmeters,

barometers, Speedometers, etc.

Slide 4: Digital Computers

These are computers that use discrete (discontinuous) values, especially binary digits (0, 1) ICT

to represent data.

The state of being on is represented by 1 and off is represented by 0.

Digital computers are more accurate and work at a very fast rate.

Examples of Digital Computers Include: All Personal computers (PCs), Laptops, Digital

Watches, etc.

Slide 5: Hybrid Computers

A hybrid computer combines the desirable features of analog and digital computers.

A digital computer that accepts analog signals converts them to digital for processing.

Hybrid computers are mainly used for specialized tasks.
