1 PARTS OF THE COMPUTER 2nd ESO IES CAP DE LLEVANT
2 1. COMPUTING OR INFORMATION TECHNOLOGY The branch of engineering science that studies (with the aid of computers)the procedure of calculating and information (data)
3 2. COMPUTER Is a machine that manipulates information or "data."
4 3.HARDWARE Are all the fisic components that makes up a computer system
5 4. COMPUTER CASE Is the metal and plastic box that contains the main components of the computer
6 5. DESKTOP CASE lies flat on a desk, and the monitor usually sits ontopofit
7 6. TOWER CASE Istallandsitsnexttothemonitororonthefloor
8 7. ON/OFF SWITCH When you poke on it the computer boots up or put off
9 8. POWER SUPPLY AND POWER CORD PLUG The computer take and convert energy from the socket to continuous voltage
10 9. BATTERY Chemical reaction which proveides energy to the computer. It's rechargeable
11 10. PORTS (pins) Madetofitonlyonetypeofplug-indevice
12 11. MOTHERBOARDS Is the computers main circuit board. It's a thin plate that holds the CPU (Central Processing Unit), memory, and expansion cards
13 12. CPU: CENTRAL PROCESSING UNIT OR MICROPROCESSOR Is a chip which acts like the brain of the computer
14 13. EXPANSION CARD Is a card which you can install to expand a computer's capabilities
15 14. VIDEO CARD Allow you to see images and text on the screen
16 15. SOUND CARD OR AUDIO CARD Lets the computer play sounds through speakers
17 16. BUS An electrical conductor that makes a common connection between several circuits
18 17. SHORT-TERM MEMORY OR RAM: RANDOM ACCESS MEMORY Data is temporarily stored here until you save your work to the hard disk. The data disappears when the computer is turned off
19 18. BIT= YES OR NO (1 or 0) The smaller unit of measurement of information (from Binary + digit)like a switch
20 19. BYTE 8BITS( )like8switchestogether
21 20. KB: KILOBYTES 1,024 BYTES like 1,024 groups of 8 switches or bits
22 1,024 KBYTES 21. MB: MEGABYTES
23 1,024 MB 22. GB: GIGABYTE
24 23. HARD DISK DRIVE (C drive) Is the data center inside of the computer
25 24. FLOPPY DISK DRIVE (diskette, A Until 1.44MB of data drive, )
26 25. CD-ROM: COMPACT DISK READ-ONLY MEMORY (until 650MB) Accesses information on a CD-ROM similar to how a CD player accesses music from a CD. CD- ROMsupto650MB
27 26. ROM: READ-ONLY MEMORY You can access the programs or data stored on CD-ROMs but you can't write or store your own dataorprogramsonthem
28 27. CD WRITER Can write CD-RW (Compact Disk ReWritable) and CD-R (Compact Disk-Recordable) discs, and read CD-ROM discs
29 28. DVD-ROM: DIGITAL VERSATILE DISC READ-ONLY MEMORY Can read DVD discs, all types of CDs, and can display movies from digital video discs
30 29. ZIP DRIVE (stores250mb) 250 megabytes on disks
31 30. USB FLASH MEMORY Known as pendrive
32 31. INPUT DEVICES Are connected to the computer through ports or sockets and are used to enter information into the computer
33 32. KEYBOARD Lets you type information into the computer
34 33. MOUSE Is the hand-held device that lets you point, click, and move objects on the monitor screen
35 34. TRACKBALL Is similar to a mouse, but the ball that helps maneuver the cursor is on top instead of underneath
36 35. TOUCHPAD You can use your finger or a tool called a stylus onapadtomovearoundthescreen
37 37. SCANNER (resolution) Allowsyoutocopyanimageintoyourcomputer. The more dots per inch, the better the resolution
38 38. HAND-HELD SCANNERS Work like scanning guns used at department stores
39 39. SHEET-FED SCANNERS Look like a printer and can scan only loose, single pages
40 40. FLATBED SCANNERS Look and act like a copy machine
41 41. MICROPHONE Usedtoentersoundinthecomputertorecord
42 42. JOYSTICK Is a leverused whileplaying a computer game
43 43. DIGITAL CAMERA (pixels) Lets you capture a picture in digital form and lets you transfer that image directly from this periferal to the computer
44 44. MONITOR SCREEN (video card) Is where the computer displays text and pictures
45 45. LCD: LIQUID CRYSTAL DISPLAY Uses liquid crystal cells that change reflectivity in an applied electric field; used for portable computer displays
46 46. PRINTER Is a machine that prints a paper copy of what youseeonthemonitor
47 47. DOT MATRIX PRINTER Produces characters and illustrations by striking pins against an ink ribbon. It can print multipage forms
48 48. INK JET PRINTER Printers shoot tiny drops of ink onto paper
49 49. LASER PRINTER It produces better quality black text documents andusuallyturnsoutmorepagesatalowercost per page than inkjets.
50 Make sound and music audible 50. SPEAKERS
51 51. EARPHONES Allows you to listening music without bother others classmates.
52 52. MODEM Allows you to connect to the Internet and communicate with other computers via a telephone line
53 53. EXTERNAL MODEM Plugsintothecomputerandsitsonthedesk
54 54. INTERNAL MODEM The modem remains in the computer case
55 36. TOUCHSCREEN. You can use your finger directly on the screen to move around
56 55. SOFTWARE Are the logic procedures or rules stored in read/write memory which manage the hardware
57 56. OS: OPERATING SYSTEM OR SYSTEM SOFTWARE Lets you use different types of application software, control peripheral devices
58 57. WORD PROCESSING PROGRAMS (Open Office writer, Microsoft Word, Corel WordPerfect) Allows you to create and edit documents, such as letters, reports, and resumes
59 58. SPREADSHEET APPLICATION (Open Office calc, Microsoft Excel, Lotus 1-2-3) Allows you to perform complex calculations
60 59. DATABASE MANAGEMENT SOFTWARE (Open Office Base, Microsoft Access) Organizes specific information in one or more tables, for example guidelines.
61 60. PRESENTATION SOFTWARE (Open Office Impress, Microsoft PowerPoint, Corel Presentations) Is designed for creating on-screen presentations, reports, overhead transparencies, and slideshows
