Output devices of Computer

Output Devices The output devices are the hardware parts which can create the whole computer system with the combination of all hardware parts. The user can get the desired output via output devices. The output device converts the data or information into the...

Computer Memory

The computer memory is the storage space in the computer and related to the hardware integrated circuits. It can store the information for immediate use on the computer. The memory is a crucial element of the computer system. Memory and data storage can be measured in...

Computer: CPU (Central Processing Unit)

What is CPU? Explain its block Diagram The Central Processing Unit is known as the central processor or main processor. The CPU is an electronic circuitry within the computer which can control the input/ output operations and carries out the instructions of the...

Computer Hardware

List of Computer Hardware Components The computer hardware includes the physical parts or components of the computer, such as to monitor, keyboard, mouse, motherboard, etc. We need software for the instructions that can be stored and run by the hardware. The software...

Block Diagram of Computer

Computer Block Diagram System: Mainly computer system consists of three parts, that are central processing unit (CPU), Input Devices, and Output Devices. The Central Processing Unit (CPU) is divided into two parts again: arithmetic logic unit (ALU) and the control...

Second Generation of Computer

The period of the second generation was from (1959-1965). The transistor takes the place of the vacuum tubes in the second generation. The transistor was invented at Bell Labs in 1947. It was far superior to the vacuum tube. The transistor is allowing the computer to...

Third Generation of Computer

The period of the third generation was from 1965 – 1971.  The integrated circuits are used in the computers of the third generation. The transistors are not used in these computers. A single integrated circuit has many transistors, registers, and capacitors grown on a...

Fourth Generation of Computer

The period of the fourth generation was from 1971- 1980. The (VLSI) huge scale integrated circuits are used in the computers of this generation. These circuits have 5000 transistors and other circuit elements. The computers of the fourth-generation become more...

Fifth Generation of Computer

The period of the fifth generation is 1980-onwards. The VLSI technology develops into ULSI (ultra large scale integration) technology in the fifth generation. These are used in the production of microprocessor chips which have ten million electronic components. The...
