What are the types of computers?

Do you know about the type of computer? All of you must have used computers, because nowadays it is readily available in all places whether they are schools or offices. At the same time, all of you must have definitely noticed that one computer does not have the same capacity to come and work.

Where some computers are very small, some are large in size. Some work very fast, some work very slowly. Now the question arises whether all these computers are of one type or they are different from each other.

Just to answer this question, in today's article, in different types of computers, today I am going to provide information about this topic to you.

Today, in this article, we will learn about all types of computers and also know how to divide them according to its function, purpose and size. Hopefully by the end of this article, you will definitely get answers to your questions. Then without delay, let's start with the type of personal computer.

what is Computer?

A computer is a machine that has been programmed to do so many of our tasks. It takes our commands according to the input, processes it and in the end provides our results according to the output.

It also has some important characteristics like

1. It responds to a specific set of instructions in a well-defined manner.

2. It executes a prerecorded list of instructions (called program).

3. It is able to store and retrieve large amounts of data with great ease.

Apart from this, computers are capable of performing many complex and repetitive procedures quickly, precisely and reliably.

Talking about modern computers, then they are electronic and digital. The actual machinery (wires, transistors, and circuits) in it are called hardware; The instructions and data are called software.

All general-purpose computers include the hardware components described below,

1. Central processing unit (CPU): It is the heart of the computer, a component that actually executes instructions that are organized by programs ("software") and those who instruct the computer what to do To do.

2. Memory (fast, expensive, short-term memory): These enable the computer to store things, even if temporarily correct such as data, programs, and intermediate results.

3. Mass Storage Device (slower, cheaper, longer-term memory): This allows a computer to sustain a large amount of data and programs in between jobs. Common mass storage devices are major in disk drives and tape drives.

4. Input Device: This is the function of input device to enter data and instructions into the computer. The keyboard and mouse are the main ones.

5. Output Device: Output device is used to show final results to users. There are display screen, printer in it.

All of you will probably want to know the type of computer. By the way, there are many types of computers, but to understand them easily, they are divided into different categories. Which will make it easier for anyone to understand them.

What are the types of computers?

They are mainly divided on three different grounds.

1. Based on mechanism

2. Based on Purpose

3. Based on Size

Based on Mechanism on the basis of methodology

Based on methodology, they are classified into three parts Analog, Digital, and Hybrid. About which we will learn one by one.

1. Analog Computers

Analog Computer is said to be those computers which use analog signal to display information. Analog computers are used to process analog data.

These analog data are of continuous nature, which are not discrete or separate. In these data, temperature, pressure, speed weight, voltage, depth etc. are the main ones.

In these, information which is of continuous form is displayed in the shape of curves. They are used to measure continuous physical quantity such as current flow, temperature, blood pressure, heart beats.

These quantities are continuous and an infinite variety of values ​​are found in them.

It measures continuous changes in some physical quantities such as a Speedometer is used to measure the speed of the car, Thermometer is used to measure the change of temperature, while the Weighing Machine is used to measure the weight. It happens for

These computers are ideal for situations where data is accepted directly from the measuring instrument and which does not require any kind of conversion into numbers or codes.

Analog computers were the first computers that were developed and celebrated the basis of modern digital computers developments.

Of Analog ComputersWhat are applications?

Analog computers are mostly used in some specialized engineering and scientific applications to calculate and measure analog quantities.

They are also used for process control, such as in oil refinery where both flow and temperature measurements are important.

They are also used for paper making as well as in the chemical industry.

Analog computers do not require any kind of storage capability as they measure and measure quantities in a single operation.

Output from an analog computer is often in the form of readings such as a series of dials (of a car in a speedometer) or in a strip chart in the form of a graph.

2. Digital Computers

A digital computer, as its name suggests, suggests that they work with digits that represent numerals, letters or any other special symbols.

Digital computers operate on the basis of inputs which are ON-OFF type and their output is also in the form of ON-OFF signal. Normally, ON is represented by a 1 and OFF is represented by a 0.

So here we can say that digital computers process information based on the presence or absence of electrical signal or on binary 1 or 0.

A digital computer is also used to process numeric as well as non-numeric data. It can also perform many arithmetic operations such as addition, subtraction, multiplication, division and also logical operations.

Most of the computers which are available in the present time are all digital computers. Common examples of Digital Computers are accounting machines and calculators.
