Computer is not an acronym, it is a word derived from the word “calculate”, which means “to calculate”. So, in simple terms, it can be said that the computer is an electronic device that is used for quick calculations. Some people say that COMPUTER full form is Common Operating Machine, which is intentionally used for educational and technological research. It’s just a myth, because firstly, this definition doesn’t make sense, and secondly, when computers were invented, they were just adding machines that needed a lot of space to set up.
Short and Simple Definition of Computer
A computer is an electronic system that uses hardware and software to provide instructions to store, retrieve, and process data. technology-based, d. H. digital, analog and hybrid. There are also various other supercomputers, personal computers, desktop computers, laptops, etc.
The computer is often referred to as a calculating machine because it cannot do anything without software. It takes the raw user data as the input process and generates the user output. In simple terms, we can say that the digital computer is an electronic device, along with its components, i. Hardware and software (as well as applications on mobile devices). It makes our lives easier by processing raw data output in whatever form into meaningful data, however the user desires. There is a large amount of software and hardware on the market that suit users’ demands.
How does the Computer work?
Two main components are required for the full functionality of the components, i.e. hardware and software. The hardware of a computer is divided into two categories, namely processing hardware and peripheral devices. The CPU is contained in the processing hardware that processes the data. , etc.) help out the user to interact with the computer.
Categorization on the basis of generation
1. The First generation computers: (1940-1956) based on vacuum tubes
2. The Second generation computers: (1956-1963) based on transistors
3. The Third generation computers: (1964-1971) based on integrated circuits
4. The Fourth generation computers: (1971 today) based on microprocessors
5. The Fifth generation computers: (present and beyond) based on artificial intelligence
Benefits of Computers
Today the way we work has completely changed thanks to the computer. Here are some advantages
multitasking computer : The biggest advantage of a computer is that a computer can do many things at the same time
Speed: Today’s advanced computer is capable of doing great things in no time.
Interesting facts about Computer
Did you know that today more than 90% of the world currency is in the computer, i.e. in digital form? The first computer was 18 square meters and weighed 27 tons. computer
Types of Computer
Computer classification based on technology
- Analog computers
- Digital computers
- Hybrid computers
- Main computers
- Micro or personal computers
Laptops and desktops are the best examples of micro or personal computers that we use in our daily life
Important Parts of Computer
A computer consists of many essential parts that we can divide into two categories: software and hardware.
All of the physical parts of a computer are known as computer hardware, such as a keyboard, mouse, monitor, etc.
It’s one of the most important lessons in a computer, and the computer’s processor is connected to the motherboard itself. The port for connecting all types of input and output devices is also located on the mainboard itself.
The CPU, i.e. the central processing unit, also called the brain of the computer or processor, processes all the data and delivers the desired result. Today, most of the computers and laptops in the world have Intel processors, and Intel’s most advanced processor is the i9.
RAM is also known as random access memory. Everything we do on the computer is stored in RAM at this point, and the information is then erased when the computer is shut down.
A hard drive is part of a computer on which we can keep the necessary information forever. The computer’s operating system is also installed on this hard drive.
