CPU (Central processing unit)

A CPU, or Central Processing Unit, is the main component of a computer system that performs the majority of processing tasks required by the system. It is often referred to as the “brain” of the computer. The CPU is responsible for executing instructions, performing calculations, managing memory, and controlling input and output operations.

The CPU consists of three main components: the control unit, the arithmetic and logic unit, and the registers. The control unit is responsible for managing the flow of instructions between the CPU and other components of the computer system, including memory, input/output devices, and other processors. The arithmetic and logic unit performs mathematical and logical operations, such as addition, subtraction, and comparison of values. The registers are small areas of memory used to store data and instructions that the CPU is currently working on.

What are advantages and disadvantages of optical fiber?

September 24, 2022 by Tanmay Chakrabarty

Optical Fiber

Optical fiber is a type of dielectric (insulating) material, such as glass or plastic, capable of transporting light. High-speed data can be transmitted through optical fibers by total internal reflection of light. The biggest feature of optical fiber is that it transmits light signals instead of electrical signals. Currently available optical fibers have a data transmission rate of 100 Mbps to 2 Mbps.

Flowchart

A flowchart is a representation of a decision sequence or algorithm. This is a series of pictures that show how to proceed in order to solve a problem. Purpose of a flowchart is to show the flow of the program. The function is to show the steps of decision sequence or algorithm in the form of diagram.

Flowcharts have to be drawn using several geometric figures of different shapes. It helps to understand the nature of the program. Programmers use these charts of flows to compose programs.

What is algorithm? What are the rules for writing algorithm? What are the benefits of algorithm?

Computer Virus:

A computer virus is a parasitic program that infects other legitimate programs, which are sometime referred as hosts. To infect the host program, the virus modifies the host to store a copy of the virus. After infection, viruses make various damages to the system which may be low to high to critical.

July 12, 2020August 27, 2018 by Tanmay Chakrabarty

Computer Hardware

Computer Hardware is any part of the computer that can be touched. These are primarily electronic devices used to build up the computer. Computer Hardware actually perform the computing operations along with taking input and sending the computed result as output or to storing that.
