- 11. ABBREVIATIONS RELATED TO OPERATING SYSTEM AND DATA STORAGE • BIOS – THIS IS THE BASIC INPUT OUTPUT SYSTEM WHICH CONTROLS THE COMPUTER, TELLING IT WHAT OPERATIONS TO PERFORM. THESE INSTRUCTIONS ARE ON A CHIP THAT CONNECTS TO THE MOTHERBOARD. • BYTE – A BYTE IS A STORAGE UNIT FOR DATA. • CPU – THIS STANDS FOR THE CENTRAL PROCESSING UNIT OF THE COMPUTER. THIS IS LIKE THE COMPUTER’S BRAIN. • MAC – THIS IS AN ABBREVIATION FOR MACINTOSH, WHICH IS A TYPE OF PERSONAL COMPUTER MADE BY THE APPLE COMPUTER COMPANY. • OS – THIS IS THE OPERATING SYSTEM OF THE COMPUTER. IT IS THE MAIN PROGRAM THAT RUNS ON A COMPUTER AND BEGINS AUTOMATICALLY WHEN THE COMPUTER IS TURNED ON. • PC – THIS IS THE ABBREVIATION FOR PERSONAL COMPUTER. IT REFERS TO COMPUTERS THAT ARE USED BY INDIVIDUALS IN HOME • PDF– THIS REPRESENTS THE PORTABLE DOCUMENT FORMAT WHICH DISPLAYS FILES IN A FORMAT THAT IS READY FOR THE WEB.
- 12. • RAM (RANDOM ACCESS MEMORY)– IT IS ALSO CALLED AS READ WRITE MEMORY OR THE MAIN MEMORY OR THE PRIMARY MEMORY. THE PROGRAMS AND DATA THAT THE CPU REQUIRES DURING EXECUTION OF A PROGRAM ARE STORED IN THIS MEMORY. IT IS A VOLATILE MEMORY AS THE DATA LOSES WHEN THE POWER IS TURNED OFF. • ROM (READ ONLY MEMORY) – STORES CRUCIAL INFORMATION ESSENTIAL TO OPERATE THE SYSTEM, LIKE THE PROGRAM ESSENTIAL TO BOOT THE COMPUTER. IT IS NOT VOLATILE. ALWAYS RETAINS ITS DATA. • VGA – THE VIDEO GRAPHICS ARRAY IS A SYSTEM FOR DISPLAYING GRAPHICS.
- 13. RELATED TO INTERNET NETWORK • FTP – THIS IS A SERVICE CALLED FILE TRANSFER PROTOCOL WHICH MOVES A FILE BETWEEN COMPUTERS USING THE INTERNET. • HTML – HYPERTEXT MARKUP LANGUAGE FORMATS INFORMATION SO IT CAN BE TRANSPORTED ON THE INTERNET. • HTTP – HYPERTEXT TRANSFER PROTOCOL IS A SET OF INSTRUCTIONS FOR THE SOFTWARE THAT CONTROLS THE MOVEMENT OF FILES ON THE INTERNET. • IP – THIS STANDS FOR INTERNET PROTOCOL WHICH IS THE SET OF RULES THAT GOVERN THE SYSTEMS CONNECTED TO THE INTERNET. IP ADDRESS IS A DIGITAL CODE SPECIFIC TO EACH COMPUTER THAT IS HOOKED UP TO THE INTERNET. • ISP – THE INTERNET SERVICE PROVIDER IS THE COMPANY WHICH PROVIDES INTERNET SERVICE SO YOU CAN CONNECT YOUR COMPUTER TO THE INTERNET. • LAN – THIS STANDS FOR LOCAL AREA NETWORK WHICH IS THE SERVERS THAT YOUR COMPUTER CONNECTS TO IN YOUR GEOGRAPHIC AREA.
- 14. • PPP – POINT-TO-POINT PROTOCOL IS THE SET OF RULES THAT ALLOW YOUR COMPUTER TO USE THE INTERNET PROTOCOLS USING A PHONE LINE AND MODEM. • URL – THIS IS THE UNIFORM RESOURCE LOCATOR WHICH IS A PATH TO A CERTAIN FILE ON THE WORLD WIDE WEB. • USB – THE UNIVERSAL SERIAL BUS IS USED FOR COMMUNICATIONS BETWEEN CERTAIN DEVICES. IT CAN CONNECT KEYBOARDS, CAMERAS, PRINTERS, MICE, FLASH DRIVES, AND OTHER DEVICES. ITS USE HAS EXPANDED FROM PERSONAL COMPUTERS TO PDAS, SMARTPHONES, AND VIDEO GAMES, AND IS USED AS A POWER CORD TO CONNECT DEVICES TO A WALL OUTLET TO CHARGE THEM. • VR – VIRTUAL REALITY SIMULATES A THREE-DIMENSIONAL SCENE ON THE COMPUTER AND HAS THE CAPABILITY OF INTERACTION. THIS IS WIDELY USED IN GAMING. • VRML – VIRTUAL REALITY MARK-UP LANGUAGE ALLOWS THE DISPLAY OF 3D IMAGES.

- 21. TYPES OF NETWORKS • LOCAL AREA NETWORK (LAN)- A LOCAL AREA NETWORK IS A RELATIVELY SMALLER AND PRIVATELY OWNED NETWORK WITH A MAXIMUM SPAN OF 10 KM • WIDE AREA NETWORK (WAN)- A NETWORK THAT PROVIDES WIDE AREA COVERAGE WITH NO LIMITS • METROPOLITAN AREA NETWORK (MAN)- PROVIDE REGIONAL CONNECTIVITY WITHIN A SMALL GEOGRAPHICAL AREA LIKE A CAMPUS
- 22. INTRANET • METHOD OF SHARING INFORMATION VIA INTERNAL COMMUNICATION CHANNELS INSIDE AN INSTITUTION • ONLY INTERNAL USERS HAVE ACCESS, NO ACCESS NO THE PUBLIC
- 23. ELECTRONIC MAIL (E-MAIL) • INVENTED BY JOHN VON NEUMANN • USED TO TRANSFER MESSAGES ONLINE • CARBON COPY (CC)- IF YOU WANT TO SEND THE SAME MESSAGE TO MORE THAN ONE RECIPIENTS, YOU CAN TYPE THE ADRESSES ONE BY ONE SEPARATING THEMSELVES WITH A COMMA. HERE ALL THE RECIPIENTS WILL KNOW WHO THE OTHER RECIPIENTS ARE. • BLIND CARBON COPY (BCC)- IF YOU DON’T WANT RECIPIENTS TO KNOW WHO ARE THE OTHERS RECEIVING THIS EMAIL, YOU CAN TYPE ADDRESSES IN BCC TEXT
- 24. • HOTMAIL- FREE EMAIL SERVICE PROVIDED BY MICROSOFT • INTERNET PROTOCOL ADDRESS (IP ADDRESS)- A NUMERICAL LABEL ASSIGNED TO EACH COMPUTER PARTICIPATING IN A COMPUTER NETWORK. IT IS A UNIQUE ADDRESS FOR EVERY COMPUTER.
- 25. AUDIO CONFERENCING • A METHOD WHERE PEOPLE FROM DIFFERENT LOCATIONS USE TECHNOLOGY TO TALK VIRTUALLY WITH EACH OTHER • ALL PARTICIPANTS DIAL INTO A CENTRAL SYSTEM THAT CONNECTS THEM
