What is a port? A port is a physical connection on a computer or another electronic device that allows users to connect a device. There are several types of ports available on personal computers that allow computers to access external …
“The computer network is a set of computers connected to share resources.”An internet itself can be considered the computer network. In computer networks, the computing devices exchange the data with each other by using the connections between nodes. The data …
Registers in Computer The Registers are the type of computer memory, which is used to accept, store quickly, and transfer the data and instructions that are immediately used by the CPU (Control Processing Unit). The processor registers may hold an …
Memory Hierarchy In computer architecture, the Memory Hierarchy separates computer storage into the hierarchy based response time. It is developed to organize the memory in such a way that it can minimize the access time. The memory hierarchy affects the …
“The computer virus is a malicious code that replicates by copying itself to another program.” It can destroy a single program or the whole software of the computer system. In the 1970s, the first computer virus was generated, known as …
The computer software is the collection of data or instruction that tells the computer how to work. It is a set of program that enables the computer to perform a specific task. It has to be “loaded” into the computer’s …
Computer Input Devices The input device is the hardware device that connects to the computer system. The user can give the instructions to the computer with the help of these input devices. Input devices can convert the data or instruction …
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 …
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 …
RAM (Random Access Memory) Vs. ROM (Read Only Memory) There are several differences between the Random access memory and read-only memory which is given below: RAM (Random Access Memory ) ROM (Read Only Memory) 1. The RAM is the volatile …

Control Processing Unit (CPU) 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 …
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. …
Computer Block Diagram 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 unit …
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 …
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 …
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 …
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 fifth-generation …
The middle-level language lies in between the low level and high-level language. C language is the middle-level language. By using the C language, the user is capable of doing the system programming for writing operating system as well as application …
Computer Languages The computer languages are those languages by which the user can communicate with the machine. There are various types of programming languages via we can write the programs. The program is the set of instructions which has to …
High-Level Language The high-level language is the programming language such as BASIC, C, C++, COBOL, FORTRAN, Java, Perl, PHP, Python, Ruby, Visual Basic, and Pascal, etc. These languages have strong abstraction, the style and the context which are more comfortable …
