Types of Computer System

Welcome to today’s class!!

We are thrilled to have you in our class!!

In today’s Information Technology class, we will be talking about the Types of Computer System 

Types of Computer System

Types of Computer System

Like humans, computers are grouped into different types. For instance, this is a teaching for primary five, however, there are other classes which also take the computer subject. 

Depending on the class you are, this will determine the number of things you are taught. Your teacher will not give you a task that is meant for a secondary school student because you are not yet capable of such tasks. 

Types of Computer System

This is the same for computers, they are grouped according to their functions and abilities. 

On the basis of data handling capabilities, the computer is of three types:

Analogue Computer

Digital Computer

Hybrid Computer


1) Analogue Computer

Analogue computers are designed to process analogue data. Analogue data is continuous data that changes continuously and cannot have discrete values. We can say that analogue computers are used where we don’t always need exact values such as speed, temperature, pressure and current.

Analogue computers directly accept the data from the measuring device without first converting it into numbers and codes. They measure the continuous changes in physical quantity and generally render output as a reading on a dial or scale. Speedometer and mercury thermometer are examples of analogue computers.


2) Digital Computers

Digital computer is designed to perform calculations and logical operations at high speed. It accepts the raw data as input in the form of digits or binary numbers (0 and 1) and processes it with programs stored in its memory to produce the output. All modern computers like laptops, desktops including smartphones that we use at home or office are digital computers.


3) Hybrid Computers

Hybrid computers have features of both analogue and digital computers. It is fast like an analogue computer and has memory and accuracy like digital computers. It can process both continuous and discrete data. It accepts analogue signals and converts them into digital form before processing. 

So, it is widely used in specialized applications where both analogue and digital data is processed. For example, a processor is used in petrol pumps that converts the measurements of fuel flow into quantity and price. Similarly, they are used in airplanes, hospitals, and scientific applications.

In summary, hybrid computers produce precise and quick results that are more accurate and useful.

It also has the ability to solve and manage big equations in real-time.
