A basic description on ports and co

1. PORTS AND
CONNECTORS

3.  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.

4.  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.

6.  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.

7. 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 enables
to join a port and a connector that are both
female or both male.

8.  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.

9.  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)

10.  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.

11.  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).

13.  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.

14.  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.

15.  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.

16.  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.

17.  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.

19.  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.

20.  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.
