Motherboard: A motherboard is a printed circuit board (PCB) that holds other modular devices, both required and additional, and facilitate communication among the devices to actually have the computer be functional. Motherboard is like a backbone to a computer system. Components like CPU, RAM, Harddisks along with additional devices like TV Cards, graphics etc. all … Read more
Instruction Set Architecture (ISA): An instruction set is the interface between a computer’s software and its hardware, and thereby enables the independent development of these two computing realms. ISA is the set of basic instructions that a processor understands. ISA includes functional definition of operations, modes, and storage locations supported by hardware and precise description of … Read more
Control unit co-ordinates the transfer of data between registers of CPU or microprocessor and ALU. Control unit serves the instructions for ALU. Along with this, control unit, as its name implies, controls every other parts of the machine, their co-ordinations, traffic etc.
Arithmetic and Logic Unit (ALU): Arithmetic and Logic Unit is a like a calculator to a computer. ALU performs all arithmetic operations along with decision making functions. In modern CPU or Microprocessors, there can be more than one integrated ALU to speed up arithmetical and logical operations, such as; integer unit, floating point unit etc. … Read more
A type of computer processors that incorporates the functions of a computer’s center processing unit (CPU) onto a single integrated circuit is called a microprocessor. A microprocessor is a VLSI (Very Large Scale Integration) Silicon Chip. Microprocessor accepts digital or binary data, processes it according to instructions stored in it’s memory and provides results as output.
CPU (Central Processing Unit) in computer: CPU or central processing unit in computer is an electronic circuitry that carries out the instruction given by a computer program. CPU in computer execute instruction by performing basic arithmetic, logical, control and I/O operations as required per instruction. CPU in computer is considered to be the brain of … Read more
Q. What are the functions of operating system? Functions of Operating Systems: Operating system’s size, organization and scope of operating vastly depends on the size, organization and use of various computer system. Obviously not all operating systems can be used on all systems. Functions of an operating system are always targeted to meet the needs. … Read more
A computer is a multipurpose electronic device that can receive, store, process data and deliver information. A computer takes data such as numbers, text, images etc. as input and then process those data and converts those to useful information. Additionally, a computer can also store data and information both for future use. Also, a computer can perform scheduled tasks. Computers are programmed devices. Computer programmers write programs or software for computer which actually takes input, process it and outputs information.
Database Administrator: One of the main reasons behind using DBMS is to have central control on both data and the applications access those data. The person who has such central control over the data is called a database administrator (DBA). Some of the functions of DBA are given below, Schema Definition: The DBA creates the … Read more
