Basic Information :
A computer is an electronic device that processes information in the data inputted by the user and provides information as a result, that is, the computer is an electronic machine that follows the instructions given by the user. It has the ability to store, retrieve and process data. You can use a computer to type documents, send emails, play games, and browse the web. You can use it to create spreadsheets, presentations, and even videos.
The word Computer has its origin in the English word "COMPUTE" which means "to calculate". Therefore, it is clear that the computer is directly related to the calculating machine, at present, its area has become very wide rather than being limited only to computation. Read more about the definition of computer in hindi to get more accurate info on this. The computer due to its high storage capacity, speed, automation, capacity, accuracy, versatility, reliability, remembering power of our life. Is becoming important in every field. Calculations can be done by the computer at a much faster time in more subtle time, the results given by the computer are more accurate. Nowadays computers are being used in every region of the world such as - space, film production, traffic, business, railway station, school, college, airport, etc. Whereas reservation of seats in airplanes, railways and hotels is done by computer, on the other hand, due to computer in banks, the work is being done with accuracy and speed.
Invention of Computer:
The invention of this is one of the largest inventions in the world. Because it changed the whole world. All work is now done from this. This has made human work very easy. Do you know who invented it and who is the father of it. If you do not know, then know that the person who invented it is Charles Babbage.
Charles Babbage is said to be the father of this who in 1822 built a mechanical computer named "Differential engine".By the way, many people have contributed with time to develop or develop it. In 1837, he introduced the first modern system to the world as Analytical engine.The Analytical engine used ALU (Arithmetic and Logic unit), basic flow control and integrated memory. Today's systems are also built on the basis of this model. This is the reason why he is called the father of the modern age system. To know about the Generation of computer in hindi might also be interesting it will give you detail info about the various inventions of computer.
Computer Parts:
It is an electronic device with many parts. You must have often seen that there are different parts to work in it. Some parts are necessary without which the system cannot function. Some computer parts are parts that we use to complete our extra work. It is also necessary to use the device for everything. So let us know which parts are there in this, without which it cannot work.There are many parts of this which are necessary. Detailed information about these parts is given below.
CPU: (Central Processing Unit)If this is called the brain of the system, then it is not a wrong thing at all. The way a person thinks with his mind and takes a decision, the CPU works like a human mind in the system.It is also known by many names, such as e-brain processor, central processor, and micro processor.This system is in the motherboard inside the cabinet. The world's first processor was built by Intel company in 1970.The CPU follows and controls instruction coming from any software or hardware. The CPU mainly consists of 2 parts.
Arithmetic Logical Unit & Control Unit:
Arithmetic and logical unit calculates both data (numerical or logical data) and makes decisions.It processes addition, subtraction, multiplication, division as well as logical data (<=> and, or). Control unit controls all the functions of the system.Controls the work of all its parts like input, output, processor.
Input Device:
The device we use to enter data inside our PC is called an input device. We enter these data and instruction in different form using the input device.An input device is a means of communicating directly between humans and the system.Input devices are devices that directly access the CPU after inputting instructions and data. The instructions from these devices tell the brain of the system what to use?There are different types of input devices that can input data and instruction. Here I am telling you about different input devices. Keyboard, Light pen, Digital Camera, Mouse, Scanner.
Output Device:
After the data is processed in the system, the devices that the system uses to output the results are called as output devices.Output device sound, video, shape, photo etc. As the user outputs the data.In the output device, we all know the monitor, printer, earphone, speaker. It is visible by outputing all the device information to us.Here I am telling you some important output devices. Monitor, Speaker, Printer, Projector, etc.
Motherboard:
The motherboard is the main circuit board of the system. All parts are connected in it.The CPU, Mouse, keyboard, printer, monitor and even devices are connected directly to the motherboard by cables. There is a hardware inside the motherboard system. We also call it the backbone of the system.Apart from PCs and laptops, there are many devices in which the motherboard is used. Devices like mobile and tablet also have motherboard.The shape and size of the motherboard of different systems vary according to the device. Some parts are connected directly to the motherboard itself.
Hard Disk Drive:
Hard disk acts as storage of a system. That is, all the data, such as videos, MP3, documents, save all kinds of files, it is called hard drive. This is a permanent storage device. In which you can store and keep data for as long as you want.
RAM:
RAM is also called main memory or primary memory or volatile memory. This is called volatile memory because it stores data temporarily. Its full form is Random Access memory. RAM increases the speed of the system. Therefore, the higher the capacity RAM, the more speed the system will work.Whenever a user works in the system, then at the time of working, store as much user as possible. But if for some reason the data is not saved and the power is lost, then all the data will also be lost. RAM i.e. temporary memory only saves the data while working. To store it permanently, it is necessary to store it on the hard drive itself.
Power Supply:
SMPS (Switched Mode Power Supply) is an electrical device that supplies power to all parts of the system.
Types of Computer:
It is Broadly divided into 3 categories based on its working. Each of which has its different types of computer
Analog - A system that uses analog signal to show information is called Analog computer. The information contained in this is in continuous form which is shown as curves. It is used in measuring continuous physical quantity such as temperature, electric current, blood pressure and heartbeat.
Digital - Systems that use binary digits to show different information are called digital computers. Information in this is in discrete form. It handles information in the form of text, picture and graphics.
Hybrid - Such systems which are capable of understanding analog signals as well as binary digits to show the information, we know on the basis of Hybrid computer.It shows information according to the operating mode. In this, the information is in continuous form as well as in discrete form as it does digital processing as well as analog processing.
