Motherboard + ports & connector

  1. 1. COMPONENT OF MOTHERBOARD ICT FORM 4
  2. 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. 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. 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. 5. RAM SLOT  The slot where the computer memory (RAM) is placed on the computer’s motherboard
  6. 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
  7. 7. PORTS & CONNECTOR ICT FORM 4
  8. 8. 1. Serial Port
  9. 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. 10. 2. Parallel Port
  11. 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. 12. 3. USB Port
  13. 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. 14. 4. FireWire port
  15. 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
  16. 16. Special purpose ports 1. 2. 3. 4. 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
  17. 17. Sound port
