What is Computer?

What is Computer: A computer is a machine that has been programmed to do many things for us. It takes our commands according to the input, processes them, and finally provides our results according to the output.

It also has some important characteristics such as:

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

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

3. It is able to store and retrieve large amounts of data very easily.

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) it contains is called hardware; Whereas instructions and data are called software.

All general-purpose computers include the hardware components mentioned below:

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

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

3. Mass Storage Device (slower, cheaper, long-term memory): These allow a computer to permanently retain a large amount of data and programs in between jobs. Common mass storage devices include disk drives and tape drives.

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

5. Output Device: The output device is used to show the final results to the users. In this, the display screen, printer are the main ones.

Types of Computer:

what are the types of computers?

All of you would probably want to know about the type of computer. Although there are many types of computers, they are divided into different categories to understand them easily. So that it will be easy for anyone to understand them.

How many types of computers are there?

Mainly they are divided on three different basis:

1. Based on Type

2. Based on Purpose

3. Based on Size

(New) Types of Computer Did You Know? (2021)

Types of Computers Based on Type:

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

1. Analog Computers:

(New) Types of Computer Did You Know? (2021)

Analog computers are called computers that use analog signals to display information. Analog computers are used to process analog data.

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

In these, the 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, heartbeats.

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

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

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

Analog computers were the first computers that were developed and the basis for the development of modern digital computers was considered.

Example of Analog Computer

  • Deltar
  • E6B flight computer
  • Librascope, aircraft weight, and balance computer
  • Mechanical computer
  • Water integrator

What are the applications of analog computers?

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

They are also used for process control, such as in oil refineries 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 capacity as they measure and compare 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 a strip chart in the form of a graph.

2. Digital Computers:

(New) Types of Computer Did You Know? (2021)

A digital computer, as its name suggests, states that it works 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 while OFF is represented by a 0.

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

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

Most of the computers that are available today are all digital computers. Common examples of Digital Computers are accounting machines and calculators.

If we talk about the results, then digital computers provide more accurate results than analog computers. Analog computers are much faster than digital.

Analog computers do not have memory whereas digital computers have them to store information. We can say that digital computers count while analog computers are used to measure.

These computers display information based on text, graphics, and pictures.

Example of Digital Computer

  • IBM PC
  • Apple Macintosh smartphones
  • Laptops
  • Calculator

3. Hybrid Computers:

(New) Types of Computer Did You Know? (2021)

A hybrid computer is actually a combination of digital and analog computers. In this, the best features of both types of computers are combined among themselves. Which are the speed of analog computers and memory and accuracy of digital computers.

Hybrid computers are used in all those specialized applications where there is a need to process both types of data. With this, they help the user in processing both types of data (continuous and discrete).

For example, a petrol pump has a processor that converts fuel flow measurements into quantity and price values.

Whereas in a hospital Intensive Care Unit (ICU), an analog device is used to measure the patient's blood pressure and temperature, which is then converted and displayed in the form of digits.

Hybrid computers are also used in scientific calculations, in defense and radar systems.

It is a computer that is capable of understanding binary as well as analog signals. Therefore, the speed is neither higher than the analog computer nor less than that of the digital computer.

Example of Hybrid Computer

  • First Hybrid Computer – Hycomp 250
  • HYDAC 2400
  • Starglow Hybrid Computer
  • HP Envy Hybrid computer

Types of Computers (Based on Purpose)

A computer is classified on the basis of purpose into two parts on the basis of Special Purpose and General Purpose.

1. General-Purpose Computers:

(New) Types of Computer Did You Know? (2021)

In today's time, the computers that are used the most are called General-Purpose computers - they are built in to perform any variety of processing jobs.

You can accomplish many tasks using just a general-purpose computer and a few different software, including writing and editing (word processing), manipulating facts in a database, tracking manufacturing inventory, doing scientific calculations. For, or to handle the security system of an organization, they are used in many such works.

These general-purpose computers can do so many different types of operations because they can easily store and execute different programs in their internal storage.

2. Special Purpose Computers:

(New) Types of Computer Did You Know? (2021)

As the name suggests, a Special-Purpose Computer is designed to perform a specific type of task, and most of the time they are used only to solve a particular problem. That's why they are also called Dedicated Computers. Because they are made to do a single task again and again.

Such computer systems can be used in graphic-intensive video games, traffic lights control systems, a navigational system of aircraft, weather forecasting, satellite launch/tracking, oil exploration, and automotive industries, a digital watch to keep track of time, or a robot helicopter Used with special care.

In this special purpose computer, you will get to see many of the same features that are in a general-purpose computer. Just in this, a special function is given more attention.

The instructions that control it are built directly into the computer so that it becomes more efficient and is also capable of very effective operation.

Since it is made to do only one task so that it gets all kinds of other things together to do the same work in a proper manner.

One of the major drawbacks is that it has negligible versatility. Which means that it cannot be used in any other operations.

Based on Size of Computer:

On the basis of size, we can divide the computer into the following categories, whose information you will get to read in the next article –
