Fundamental of computer?
Fundamental of computer Definition: The general meaning of the word computer is the computer. The Latin word compute means counting or calculating the meaning of the word. Computers can perform tasks like addition, decomposition, multiplication, division, etc. The computer’s multi-faceted use has resulted in a lot of computer-generated transmissions. (No more computers can be broken with a limited number.)
Who is the inventor of the computer?
The relationship between Bit, Byte, KB, GB and:
The ability to hold the number of bits, bytes or computer sounds in computer memory is usually expressed by bytes. But it is important to say that the number of bits is the smallest unit of the system.
8 Bit = 1 Byte
1024 Byte = 1 Kilobyte (KB) [1 Byte = 1 Character]
1024 Kilobyte = 1 Megabyte (MB)
1024 Megabyte = 1 Gigabyte (GB)
1024 Gigabyte = 1 Terabyte (TB)
Questions and answers about computers
Question: 1. Who is the computer brain of the CPU?
Ans: CPU (Central Processing Unit) is the most important of the computer’s organizing parts. Mathematical analysis, logical layout, control and storage of the information required for a specific time when working on the computer; In a word, all processing is done in this part.
Just as the brain of the soul keeps the body active by controlling all the functions, the computer CPU keeps the computer functional by performing all the functions. That’s why Cpu is called the brain of a computer.
Question: 2. Write down some important features of the computer.
Ans: Accuracy, speed, accuracy, reasonable decisions, pluralism, memory, automation and tolerance.
Question: 3. What are the basic limitations of the computer? Do computers have the power of thought?
Ans: Computer is just a device. It has no thought power, no intelligence or judgment analysis and decision making power through consideration.
Question: 4. Write down the features of computers of different generations.
Ans:First Generation (1951-1959)
- Memory is very small;
- Vacuum tubes;
- The memory of magnetic drums;
- The program run using code;
- The computer has a high cost of maintenance and power, and
- Programs were written in mechanical language on this generation’s computers.
Ans: Second Generation(1951-1959)
- It could have used module design to create the main parts of the circuit on separate boards;
- Small in size, more speed, and less power and heat production;
- Created by transistor and memory magnet core and
- the program was written in assembly language.
Ans: Third Generation (1965-1971)
- the use of a broadly integrated circuit;
- The power costs are low because of the size smaller and
Ans: Fourth Generation (1971-present)
- A large amount of memory and high speed and
- Data transfer using telecommunication lines.
Question: 5. What is Abacus?
Ans: Abacus is a structure of four-cornered wood with a small circle or a folded wire. As the computer of today, Abacus considers the number as a signal or code – the location of the wire and the presence of the cables in the structure determines the signal.
It is believed to have been discovered in Babylon in 3000 BC. Abacus can usually be used to determine the sum, the decomposition, the quality, the division, the square, and the square root.
Question: 6. What is the analytical engine?
Ans: Charles Babbage started planning an accounting machine capable of any kind of accounting in 1834. So that there were plans to run the program and save the accounting instructions on the punchcard. This device is the analytical Engine.
