OUTPUT DEVICES

LIQUID CRYSTAL DISPLAY PROJECTOR Output from a computer on a large screen. Commonly used – meeting and conference.

Braille Printer Produces Braille Printouts from the computer. It works with software that translates text to Braille.

Plotter Printing device used for creating high-quality graphics, charts, graphs, tables and diagrams. Commonly used in Computer Aided Design(CAD) and Computer Aided Manufacturing(CAM)- Houses, car parts, machinery. Plotter are of four type- Drum Plotter Micrographic Plotter Inkjet Plotter Flatbed Plotter.

software Computer Program used to run the System. Program is a sequence of step-by-step instruction to preform a particular task. Software system application

System Software: Refers to the program designed to have control over the system. Software are been classified as System Software Operating System compiler Assembler interpreter Driver

Operating System: Master Control system, that run the system. It controls all the signals that runs from the CPU. First program that loaded into the memory when the computer is switched on. Eg: Windows, Android, linux and Mac OS

Reads the entire program at once and then translate it. Compiler Interpreter Translate the High level Computer language program into machine language. Reads the entire program at once and then translate it. Display an error message with the line number. Eg: Object Program Translate one statement of a high level computer language program into machine and execute it. Next statement is proceeded. Till the entire program is translated. They are small program than a Complier.

Driver: Computer Program used to enable a computer to interact with the hardware devices. Eg: printer, pen drives. Assembler: Translates assembly language program into machine language.

Application Software: Used to help user to do some work. Package MSOffice 2013 Utility Create a backup Anti Virus software

Computer Language Computer Language Machine Language Code(1 & 0) Low-Level (No Translation) Machine Language Code(1 & 0) Assembly Language(Start, End, Move) High-Level(Source program)-Interpreted and Compiled COBAL, BASIC, FORTRAN, C, C++
