Computer hardware and computer software

To make and operate a computer, mainly two things are necessary in it. The first is Hardware and the second is Software.

No computer can run without these two. Both HARDWARE and SOFTWARE are complementary to the computer, so let’s know about Computer Hardware and Software.

Hardware

The most important thing for any computer is its hardware, hardware is those things which we can see and touch. Such as Hard Disk, Dvd Drive, Motherboard, Speakers, RAM, Processor etc.

Computer is made with the help of these hardware. If even one of these essential hardware’s in the computer is less or gets damaged, then your computer will not work.

Software

Computer software is most important after hardware, when you start any computer, you see an interface called Windows where you do web browsing and store your data.

The main job of software is to control your computer hardware and run it according to your command. Without software the hardware of your computer does not work.

Software is a type of program that is created for different purposes. For example, if you want to store any type of data in your computer, then with the help of software, you can copy and store the data in your hard disk.

Parts of Computer

➤ Motherboard

Motherboard is one of the most important parts of the computer which connects all the things of the computer and makes them workable.

Along with the motherboard, all types of connectors are added such as USB, Speakers, Processor, Ram, Power Supply unit, Cables etc.

Without this you cannot even use the computer.

➤ Mouse

Through Mouse we can select any option in Computer and with Mouse you can work faster than Keyboard. Mouse is the most necessary thing to use the computer.

Without this, you will have a lot of difficulty in operating the computer and you will not be able to use the computer properly.

Computer Mouse is an Input Device that inputs the user’s instructions into the computer according to which the computer works.

We can also call the mouse as a Selector, by which many such things are done from Select to Open any Folder or File, Drag, Copy / Move etc.

Like the keyboard, the mouse is also an integral part of the computer, which is used in about 95% of the tasks in the use time of the computer. Mouse has a huge contribution in the computer era because it has made the work of computer very easy.

There are many types of mouse according to different tasks.

If any user wants to learn how to operate a computer or learn all things about a computer, then they must learn and know what a mouse is.

So we can say one thing with confidence that mouse has really made the use of computer very easy and in future we can get to see many types of mouse as well.

Although there are many buttons in the mouse, but mostly 3 buttons are used.

left button
right button
scroll button

⑴ Left Button – Most of these are used for the Left Button, which is mostly used to open or close any Task.

⑵ Right Button – It is used to see the options of any Task, then according to that Options, further Tasks are performed.

⑶ Scrolling Button – Scrolling Button is used to scroll the Task Page from top to bottom or Left to Right or Right to Left which is very useful.

Keyboard

Keyboard is also the most important thing to use the computer.

You cannot type anything in computer without keyboard. Keyboard gives us the freedom to type any word in the computer according to our own.

Whenever you have heard the name of computer, you must have heard the word keyboard along with it. So let us tell you that keyboard is such a device without which you will not be able to do 75% computer related work.

You can input data into the computer only from the keyboard and that is why the keyboard is called Input Device. Keyboard is used in almost all computer related work.

Nowadays, people who want to learn about computer, they definitely think that what is keyboard, complete information?

So Keyboard is an Input Device by which data is input into Computer CPU and it is very important Input Device.

It is almost impossible to run a computer without a keyboard.

It is very important to have a keyboard to run a computer, whether you use a physical keyboard or a virtual keyboard.

➤ Power Supply Unit

The Power Supply Unit supplies the right amount of power to the computer and protects the computer from electrical damage.

➤Processor

Processor can also be called the brain of the computer because it is the only thing that helps the computer to run and solve all kinds of calculations.

Without this, you cannot do any kind of work in computer.

You can see Processor in every small electronic device which is used to solve calculations.

➤ Spikers

We mostly use speakers to listen to music or while watching movies.

But in today’s time, as all Office Related Meetings and Online Education is happening, in such a situation, the use and need of Speakers has also started increasing.

Monitor

Monitor is such a part of the computer without which we cannot operate the computer or we cannot see the things happening in the computer.

We can see computer functions visually only through the monitor.

If there is no monitor in the computer, then you will not be able to see anything, nor will you be able to do any work properly or give instructions to it.

➤ DVD Drive

DVD Drive is not so important in today’s time.

In today’s time, we have mostly started using Cloud storage or Usb Drives to store or carry the data, but DVD DRIVE has some advantages of its own.

For example, if you have some data that you want no one to delete, in such a situation, you can write and keep the data through DVD Drive and use it anytime.

➤ Hard Disk

Hard Disk Drive is one of the important parts of the computer, which is used to store all types of data in the computer.

In today’s time, SSD has replaced Hard Disk, which is many times faster than Hard Disk and it also lasts for a long time.

Along with this, it also consumes less power.

RAM

Friends, if you do not know what RAM is, then let us tell you that RAM stores the short term memory of the computer. The full form of RAM is “Random Access Memory”.

In this, the data is stored only for a short time and as soon as you restart or turn off the computer, then this data itself gets deleted.

But this is the most important part to keep the computer working and for your computer to work fast, you should always use RAM with more memory capacity.

➤ Graphics Card

The work of Graphic Card is mainly to process Graphics. Whatever you see Visually Image or Video in Computer, all that is possible only with the help of Graphic Card.

If Graphic Card is not present in a computer, then you will see all the things only in Numeric Form, which you will not be able to understand at all.

Computer Operating System

Computer Operating System is that Program Software by which the entire computer is operated and which manages all the operations of the computer and hence it is called “Operation System” .

Whatever operation is done in the computer, from turning on to shutting down, the entire operation is managed by the operating system.

No matter what digital device you use, about 90% of the devices use the operating system, whether it is a mobile, a computer, or any other digital device. Whoever learns a computer must know and learn that the operating system What ?

The first operating system in the computer world used to be DOS, in which all the work was done from Coding Line, but as soon as Bill Gates launched the Windows Operating System, after that the nature of the Operating System changed.

The Windows Operating System had shaken the entire Computer World and the same Operating System had made Bill Gates the world’s number 1 rich. Apart from this, there are many other operating systems like Apple’s MAC, Linux, Android and Ubuntu.

Today, Android Operating System is used in about 80% of mobiles in the world and that is why it is called Android, which is an Operating System, while iOS Operating System is used in Apple’s phone IPhone.

Without Operating System, you will not even have a Computer, Mobile, ON. The Operating System itself manages all these operations. Each and every work of Digital Device is possible only because of the Operating System.

Invention of computer

Charles Babbage is called the inventor of the computer.

He made the first mechanical computer in the year 1837, which was known as Analytics Engine at that time and data was entered in it through Punch Card.

In this, the concept of ALU, Basic Flow Control and Integrated Memory was implemented.

All today’s computers have been designed on the basis of design from this node and because of this contribution, he is today called the father of computer.

How was computer made?

We can say that the first computer was made by Abacus or its descendants, which was made by Slide Rule William Oghtred in 1622, but today’s modern computers are all based on Analytic Engine.

It was conceived by British Mathematician Charles Babbage and it was designed in 1833, but before that computer used to be a person who used to do all kinds of calculations and they were stored in books.

Till that time tables used to appear only in books.

After the invention of the Analytic Engine, there were continuous improvements in it, and later on, Silicon Chips were used in computers, which increased the processing power of the computer to a great extent.

History of computer

No one knows exactly how the computer started to be made, but the purpose behind making the computer was that the biggest calculations could be solved quickly and correctly.

But in the world of computer, there were some such inventions in the early times that changed the whole of computer and today you are able to carry computer with you.

And the first computer that was made was about the size of a large room and it took more energy and manpower to run it, so let’s know about Computer Generations, how the world of computers changed and what happened to us. Had an impact.

1. First Generation Computer (1940 – 1956)

The first generation of computers was made between 1940 and 1956. In this computer, Vacuum Tubes were used for circuitry and Magnetic Drum for memory.

About 18000 Vacuum Tubes were used in it and it used to occupy a lot of space and it also required a lot of power to use it.

Due to the large size of this computer, it used to produce more heat, which was a big problem and UNIAC and ENIAC Machine Language were used in it.

2. Second Generation of Computer (1956 – 1963)

The second generation of computers came between 1956 and 1963, due to which there was a huge change in the computer field.

Vacuum Tubes were replaced with Transistors in Second Generations Computer.

Along with being very small, they also used to occupy less space and they used to consume less energy and were also fast, but the problem of heat still remained, but they used to release less heat than the first generation computers.

3. Third Generation of Computer (1964 – 1971)

The third generation of computer came between 1964 and 1971. Integrated Circuits were used in this.

In this, small transistors were inserted in the silicon chip which was called Sami Conductor.

A big advantage of this was that the processing speed of the computer had increased considerably.

Third Generation Computer was first launched for the people in the market and it used Monitor and Keyboard and Operating System which was quite User Friendly.

4. Fourth Generation of Computer (1971 – 1985)

Microprocessors were used in the fourth generation of computers from 1971 to 1985.

It was designed in such a way that thousands of integrated circuits were embedded in a silicon chip, which helped a lot in reducing the size of the computer and the processing capacity of the computer also became much faster than before.

5. Fifth Generation of Computer (till now)

After 1985, the Fifth Generation of Computer started, which is still going on. Artificial Intelligence is being made in this.

It is so powerful that when it is fully developed, it will have so much capacity that it will be able to think and take decisions on its own.

Computer made in india

The first computer in India was made by Tata Institute of Fundamental Research Automatic Calculator in 1950 and this computer was fully used in 1965.

2700 Vacuum Tubes, 1700 Germanium Diodes, 12500 Resistors were used to make this computer.

Its word memory capacity was 2,048 40-bit.

Can we also make computers?

Yes, anyone can make a computer, but for that you need to have complete information because there are many sensitive parts in the computer which can be damaged if wrongly jointed.

In today’s time, competition has increased a lot in the field of Computer Manufacturing, this is because of its increasing Demand.

If you want to make and sell your own computers, then first of all you have to hire some people who have good knowledge and experience about computer and its manufacturing.

After that, you will have to keep workers doing many other types of work in your company so that you can get the productions of computers.
