2. CPU




Controls the operation of the computer
It interprets and carries out the basic
instructions that operate a computer
On personal computer, all function of the
processor usually are on a single chip
Term microprocessor – refer to a personal
computer processor chip.

3. EXPANSION SLOT



The socket where the circuit board or the
adapter cards can be inserted into the
motherboard
Engineered technique for adding capabilities
to a computer
PCI & ISA

4. EXPANSION CARD



Plugged into an expansion
slot
Used to added new
devices or capabilities to a
computer
Card may come in one of
sizes designed to match
standard slot dimensions

5. RAM SLOT

The slot where the computer memory
(RAM) is placed on the computer’s
motherboard

6. PORTS & CONNECTORS



A port is the point which a peripheral
attaches to a system unit so that the peripheral
can send data to or receive information from the
computer
Ports have different type of connectors. A
connector join the cable attaches to a peripheral
One end of cable attaches to the connector on
the system unit and the other end of the cable
attaches to a connector on the peripheral

8. 1. Serial Port

9. 1. Serial Port


Used to connect a modem, data
acquisition terminal or other serial devices
via slow-speed serial interface
transmitting data a bit a time

10. 2. Parallel Port

11. 2. Parallel Port




Socket on computer used to connect a printer or
other parallel devices
Transferring information more than one bit a time
Developed as an alternative to the slower speed
serial port
Can transfer 8 bits of data (1 byte) simultaneously
through 8 separate lines in a single cable

12. 3. USB Port

13. 3. USB Port



Can connect up to 127 different
peripherals together with a single
connector
Transfers data to a speed of 12
megabits per second
Replacing the serial and peripheral ports
on a PC, at least 4 USB ports are
standard on every computer

14. 4. FireWire port

15. 4. FireWire port




Similar to USB port : can connect multiple
types of device that require faster data
transmission speeds
Cam-coders & other video equipment use this
port to transmit data
Transmit data 400 Megabits per second
Up to 63 devices can be daisy-chained to one
Fire-Wire port

MIDI port : design to connect the system
unit to a musical instrument such as
electronic keyboard
SCSI port : special high-speed parallel-port
used to attach peripheral devices such as
disk drives and printer
IrDA port : transmit data via infrared light
waves. Both computer must have a IrDA
port
BlueTooth port : use radio wave to transmit
data between two devices
