Transcript of 1 Ports and Connectors
Ports and Connectors
ATX Ports
Soldered on
motherboard
Back plate included
No extention wires
DB Connectors
DataBus or DB connectors have a slight D-shape
Male DB connectors have pins
Female DB connectors have sockets
Oldest type of connector in the PC
Parallel / LPT
Serial / RS-232
Serial Ports
Serial ports are used
to add external
devices to a PC
Takes a stream of
serial data from the
CPU and outputs it
in a serial format
9-pin or 25-pin
serial ports
DIN Connectors
DIN connectors are round
and come in two sizes
DIN
Mini-DIN
Always a female connector
Used frequently by a
keyboard or mouse
Modem
Modems work with your telephone to translate analog telephone signals into digital serial data or vice versa
Internal modems are expansion cards
External modems connect to a serial port
Uses two RJ-11 sockets
One to the telephone jack on the wall
One to a telephone if you wish
RJ Connectors
Registered Jack or
RJ connectors are
used by module
telephones (RJ-11)
and network cards
(RJ-45) and plug into
appropriate ports
Network Cards
PCs connect to other
PCs to share
information or
devices using a
network interface
card (NIC)
Connectors include
RJ-45, BNC, DB
Sound Cards
Sound cards
Takes digital information and turns it into sound
Take sound from a microphone and turns it into
digital data
Use mini-audio jacks for speakers and microphones
Use a 15-pin DB socket for a joystick or musical
instrument
USB Connectors
Universal Serial Bus (USB)
Used by many devices today
Devices are hot-swappable
Meaning you can insert or remove the device while the PC is running
May daisy-chain multiple USB devices together
USB Ports
Universal Serial Bus Theoretically allows up to 127 devices on a
single port.
Practically 4 – 6 devices can be connected
Uses a 4 wire cable
Hot swappable
There are now two USB standards: USB1.1
Will run at 1.5 or 12Mbps (Megabits per second)
USB2.0
Will also run at 480 Mbps
USB "A" and "B" connectors
"A" connectors head "upstream" toward the computer.
"B" connectors head "downstream" and connect to individual devices.
Different connectors on the upstream and downstream helps prevent confusion.
USB 3.0
Super Speed or SS
USB 3.0
FireWire Connectors
FireWire connectors move data at incredibly high speeds Also known as IEEE 1394
6-wire cable
Cables may be no longer than 5 meters
High speeds of 100-400 Mbps
Supports daisy-chaining
Hot-swappable
Firewire Ports
FireWire, originally created by Apple and standardized in 1995 as the specification IEEE-1394 High Performance Serial Bus.
Will support as many as 63 devices on a single controller.
FireWire has three different transfer speeds: 100, 200 and 400 Mbps
Camcorders, printers and storage devices are typical of devices connected to Firewire.
Firewire is platform independent.
Video Cards
Keyboard
Keyboards come in many sizes and shapes Use a keyboard port on
the motherboard
DIN connector is obsolete
Mini-DIN is most common today
USB connectors are sometimes used today
Use the same kind of connector as a mouse but most PCs clearly mark the connectors
Mouse
A mouse allows you to select graphical
items on a screen
Early computers did not need a mouse
Mice used to connect to the PC thru a 9-pin
or 25-pin serial port
Now mice connect thru a mini-DIN (or PS/2)
port which is also serial
Today mice may use a USB port
Trackballs may be used instead of mice
Mouse motion intereption
Mechanical Mouse
Incremental rotary encoder
Centronics Connectors
Centronics connectors have a
D shape with one large central
tab
Uses contacts instead of pins
Still called pins, though
Uses wire rings to hold
connector on
Older printers use a 36-pin
Centronics socket
Printers
Impact Printers
Dot Matrix
Daisy Wheel
Band and Chain
Non Impact Printers
Ink-Jet
Laser/Page
Thermal
Joystick
Joysticks are used
almost exclusively to
play games on the
computer
Originally designed as
an input device to be
used much like a mouse
