need high quality images

7. Inputs

8. Motherboard
A motherboard or mainboard is a printed
circuit board of microcomputer or PC the
allows communication between other
electronic

9. CPU
 Central Processing Unit
 The Brain of the computer
 Measured in MHz (Megahertz) and GHz (Gigahertz)
Hertz = Cycles Per Second
Mega = 1,000,000
Giga = 1,000,000,000

10. Memory
 Ram (Random Access Memory)
 Temporary
 Flexible
Operating System and a program loaded
into the system memory. When a system
run low on a available memory, the
computer will run more slowly

11. MEMORY MEASURED IN
Based on bit – 0 or 1 On/Off
Byte = 8 bits
K = Kilobyte = 1000
MB = Megabyte = 1,000,000
GB = Gigabyte = 1,000,000,000
TB = Terabyte = 1,000,000,000,000
PB = Petabyte = 1,000,000,000,000,000

12. Output Devices
 Monitor
 Printer
 Sound

13. Monitors
CRT – cathode – Ray Tube The cathode
ray tube (CRT)
vacuum tube containing an
electron gun
LCD Display – Liquid Crystal Display A
liquid crystal display (LCD)
thin flat panel used for
electronical displaying
information
PDP – A plasma display panel
Flat panel – TV display

14. Printers
 Laser printer
Laser printers use toner power
instead of dye or pigment-based
ink
 Inkjet printer
Inkjet printers are mainly use for print
text, graphics, and images onto various
type of paper

15. Sound
 Computer can run audio from the
basic sound capabilities built into the
systems or for improved audio using a
audio card
 Built in Speakers
 External Speakers
 Headphones
