Computer components is a programmable machine that receives

Computer components is a programmable machine that receives input, stores and manipulates data, and provides Computer output in a useful format. Hardware Software The computer programs (sequences of instructions) that tell the computer what to do in response to a command or some event. The physical components System Memory System (electrical circuits) Memory that make up the computer holds the data that the computer will process Processor Application These devices translate Central Processing Unit and the instructions that consists of operating systems, language electronic signals into (CPU) or microprocessor, indicate what programs to perform translators, andspecific utility mechanical controls the operation ofprograms. the processingmotion is to beordone. functions specified Input/Output devices Coordinates the various parts of the light (or vice versa) so as computer and performs by endits users. Must computer system and mediates between to communicate with data processing functions. operate through the application software and computer people system software to work hardware.

Scanner are Web sent over the address bus to identify a camera particular location in memory or Microphone input/output port Hardware Address bus RAM random-access memory ROM read-only memory CPU MEMORY I/O DEVICES Main Input Secondary Output reads and interprets the program instructions, transforming them into a series of control signals which two way path for transferring data activate other parts of the computer and instructions in and out of the Control unit (CU) Arithmetic/ logic unit Data bus microprocessor (ALU) is not directly accessible to the Control Lines bus requiring perform the set of CPU, arithmetic and the use of computer. The control bus synchronizes input/output channels. logic operations: adding, subtracting, system events like memory Magnetic multiplying, dividing and etc. disk (Hard disk, Flash) access, system interrupts, Optical media (CD, DVD ) I/O, etc

a software, which makes a computer to actually work, enables all the programs we use, organizes and controls the hardware, acts as an interface between the application programs and the computer hardware. Examples: Windows, Linux, Unix and Mac OS, etc. , Software Operating system converts high level language into low level language & vice versa as computer can help to perform specific tasks inonly the understand in binary format areas: Data management Documentation Collaborative and Content access Entertainment Media development and etc. Language translator Utility programs Prewritten programs that can be used rapidly when requested for routine, repetitive tasks: is a programming language Copying, setting or up new programming environment files, deleting old files, designed with a specific purpose in so formatting diskettes and mind, such on as the development of commercial business specially written code usedsoftware for writing (DBMS) (C++, Java). applications.
