Ports and connectors

  2. 2.  The point at which a peripheral attaches to. Communicates with a system unit so that the peripheral can send data to or receive information from the computer.
  3. 3.  External devices often attaches by a cable to a port on the system unit. The term JACK is sometimes is used to identify audio and video ports. The front and back of system unit on desktop personal computer contain many ports. The ports of notebook computers including netbook and Tablet PCs are on the back , front and sides.
  4. 4.  Joins a cable and a port. A connector at one end of the a cable attaches to a port on the system unit. A connector at the other end of the cable attaches to a port on the peripheral.
  5. 5. Male Female Have one or more  Have matching exposed pins (end of holes to accept the an electrical cord). pins on a male connector or ports (electrical wall outlet).• Gender changer is a device that enablesto join a port and a connector that are bothfemale or both male.
  6. 6.  Universal serial bus port Connect to up 127 different peripherals together with a single connector. USB 2.0 (Hi-Speed USB) more advanced and faster than USB. USB 3.0. USB 2.0 & USB 3.0 are backward compatible (they support older USB devices as well as USB 2.0 & USB 3.0) To attach multiple peripherals using a single USB port, can use USB Hub.
  7. 7.  A device that plugs in a USB port on the system unit. Contains multiple USB ports in which can plug cables from USB devices. Self-powered or bus-powered Self-powered USB hub draws power from an electrical outlets whereas bus-powered USB hub draws power from USB bus in the computer. Wireless USB hub is a receiver plugs into a USB port on the computer and it communicates wirelessly with the receiver. USB supports hot plugging and Plug and Play (attach peripherals while the computer is running)
  8. 8.  IEEE 1394 port Connect multiple types of devices that require faster data transmission speeds. The three latest version (FireWire 800, FireWire 1600 and FireWire 3200 ) have speeds faster than the original FireWire 400. Use FireWire hub to attach multiple devices to a single FireWire port. Supports Plug and Play.
  9. 9.  Bluetooth technology uses radio waves to transmit data between two devices. Have to be within about 33 feet to each other. Contain a small chip that allows them to communicate with other Bluetooth-enabled computers or devices. Bluetooth headsets allow smart phone users to connect their telephone to a headset wirelessly. Bluetooth wireless port adapter that will convert an existing USB port into a Bluetooth port. Bluetooth PC cards and ExpressCard modules (traditional notebook computers and Tablets PCs). Bluetooth cards (smart phones and PDAs).
  10. 10.  A special high-speed parallel port. Allows to attach SCSI peripherals (disk drivers and printers). SAS (serial-attached SCSI) transmits at mush faster speeds than parallel SCSI. For small computer system interference can daisy chain up to either 7 to 15 devices together.
  11. 11.  External Series Advanced Technology Attachment. Allows to connect an external SATA hard disk to a computer. SATA hard disks are popular because of their fast data transmission speeds. Connections provide up to 6times faster data transmission speeds than external hard disks attached to a computer’s USB or FireWire port.
  12. 12.  Infrared Data Association. Transmit data via infrared light waves. For these wireless device, to transmit signals to a computer, both the computer and the device must have an IrDA port. Align the IrDA port on the device with the IrDA port on the computer. Example : smart phone, PDA, keyboard, mouse and printer. Several of these devices use a high-speed IrDA port, sometimes called a fast infrared port.
  13. 13.  A type of interface that connects a device to the system unit by transmitting data one bit at a time. Some modems that connect the system unit to a telephone lines use a serial port because the telephone line expects the data in a specific frequency.
  14. 14.  Musical Instrument Digital Interface. The electronic music industry’s standard that defines how devices (sound cards and synthesizers) represent sound electronically. A special type of serial port that connects the system unit to a musical instrument. (electronic keyboard). A synthesizers can be a peripheral or a chip, creates sound from digital instructions. Has the capability of recording sounds that have been created by a synthesizer and then processing the sounds (the data) to create new sounds.
  15. 15.  A port replicator is an external device that provides connections to peripherals through ports built into the devices. The mobile user accesses peripherals by connecting the port replicator to a USB port or a special port on the mobile. Sometimes the port replicators disable ports on the mobile computer to prevent conflicts among the devices on the computer and the port replicator.
  16. 16.  An external device that attaches to a mobile computer or device, contains a power connection and provides connection to peripherals. Similar to port replicator, but it has more functionality. Usually includes slots for memory cards, optical disc drivers, and other devices. Users can work with a full-sized keyboard, a mouse, and other desktop peripherals from their traditional notebook computer, netbook or Tablet PC.
