COMPONENT OF
MOTHERBOARD
ICT
FORM 4
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.
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
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
RAM SLOT
The slot where the computer memory (RAM) is placed on the computer’s motherboard
PORTS & CONNECTORS
A port is the point which a peripheralattaches 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
PORTS & CONNECTORICT
FORM 4
1. Serial Port
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
2. Parallel Port
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
3. USB Port
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
4. FireWire port
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
Special purpose ports
1. MIDI port : design to connect the system unit to a musical instrument such as electronic keyboard
2. SCSI port : special high-speed parallel-port used to attach peripheral devices such as disk drives and printer
3. IrDA port : transmit data via infrared light waves. Both computer must have a IrDA port
4. BlueTooth port : use radio wave to transmit data between two devices
Sound port
