## Unprocessed - (Username - password) - Dalia - Information technology : - Information : Processed data - Website ## Types of Computer - Analogue - Digital - Hybrid - Adu. Speed - (Memory accuracy) - (Speed) - (Digits numbers) - (Memory accuracy) - Continuous . De data - Ex: 4 temperature, pressure - (Real Numbers) - infinite - 1-2-3 - Numbers - Binary - Numeric - (off) signal - Non-numeric - (on) signal = 1 ## What's defenation of (data)? Anything in a form suitable for use with a computer ## Procced data ? Information. ## Program ? Computer instructions. ## Computer operations **Input** - Information. Data - Deliver to computer - Manually - Data gathered Auto - By - Facts given - Program - instructions direct - Commands - Keywords - User response - User answers - To Computers - Questions - "Cru" **Process** - Converting "" - Input **Output** - Anything - Comes out - At Timeli **Control** - Following - Computes - Operations - Peform task - User response - Stored printed on paper - Printed atask - Cored - Soft copy - Screen - Can transfer - From - To - Data - Coordinas - Acting Davis - One memory - Control - Directing - The - Manner - Sequence - in which all - The - Operation - Are to - Be - Perform **Output** - Text document - Graphic - Multimedia **Hard ware : parts** - of Computer has - *Physical structhe - Monitor - As - Keyboard **Soft ware:- set of instructions** - That - guides The hard - tells it How - to accomplish it's - Perform - fast ## Computer Components - **Systemunil** - The "Brawn" of This - unit is - Computer Cise - * all Components - are stored There - * Contains all the - actud computer - Components - bundled withe - Power supply - * The "RAM" randam - access memory ? - Extemporanilly stores - informatics while - Cumpler is an - = Computer - Memory - **131** - Central Proccesing - Can - operate - Als - wit - (Cpu) - * The Braing - sends power to - other hardwar - all - * So They - tower Case : designed - Stand upright - To - Desktop designed - Case - to - Lay - flat on the - Desk - **112** - Sends power to - other hardwar - all - * So They - tower Case : designed - Stand upright - To - Desktop designed - Case - to - Lay - flat on the - Desk - Advanced Technolyy - ATX P-s - Advanced Techndg - Exterdad - Computer - performs the - system's - Calculatiny - Processing - Advanced Technolyy - ATX P-s - Advanced Techndg - Exterdad - Cpu - Fan - Cooling - Purpose - Computer - Memory - * Stores - informatre - in electr - devices - The "Braing" - Advanced Technolyy - ATX P-s - Advanced Techndg - Exterdad - Cpu - Fan - Cooling - Purpose - Computer - Memory - * Stores - informatre - in electr - devices ## Computer Categories - **Mobile Computer** - * transportaed - duning Normal - usage - **Micro Computer** - * Com. with - as (CP) - Car - * used ley - individues - For Single - user - **Mini Computer** - xlre betwees - work - main - Statens - Frames - * Multi-processing - System - kaused by - Hundreds - users - **Main-Frames** - More powerful - Than Supercomputers? - Becuse they support - More Simultereaus - Programs - **Superf Comp** - * The Fastet - Type of compu - * uses fo - applications - That requins - huge apar - **Note** - * - But supercom - Faster - Than it - used in Lary - areas as - governments - Banks - large - Corporation - **Mathematice** - Calculatie - Numeredu - Focusd - as - Cal Cutaten - weather - nuclear - Simutat - Forcasting - **Complex** - *Scertifie - Computaten - **Smart tablet ultha** - Phone campie M-PC - PPA - Wearable - Personal - سيئة الساعة - digital - ir al assustat - **Tower PC** - Hid - Disktop laptop - Server - Tower work - PC - State - uses as a - server - **5611 workstation.** - * More powerful Thos - Micropra and higher - Quality - used for - Engneering applicatis (CAD/CAM) - * used for - Sort ware development / Desktop pubiony - Reavores hieroph - Graphics capability ## Hard disk optical - * used to store - Computo data. - srogramme - * It's faster tha٠٠ - Floppy disk - and Cand hold - More deta ## Motherboard - The main - arcate board - enternd - * where cell Keys exteral - Components of comput - Plug into - crfu - Suses - AS - Chipset YRAM ROM - BIOS ## Video Card - * gaves - adds - display - Capability - display ## Disk - Stores - + play's - Back date - * Receit - Disk - drive - Reads - 1. both - X ## Modem. - Ports - * Modulator-demodilater - * Device enables The - Corpputer to transmit data - over ## Monitor - * Allows you - To see what - The Computer - processing ## Audio Card - Logrod - arany Moniter - * providing - high - Qudity - Stereo - output - To The - Speakes ## Telephone Cable Lines - AS
