Chapter 3/ peripherals and Expansion Flashcards
Expansion card also known as adapter card. definition
3-129
is a circuit board that we install into a computer to increase the capabilities of that computer.
Video card
3-130
Alternatively referred to as a display adapter, graphics card, video adapter, video board, or a video controller, a video card is an internal circuit board that allows a display device such as a monitor to display images from the computer. video cards work batter with PCIe then AGP and PCI slots.
Sound cards
3-131
Alternatively referred to as a sound board or audio card, a sound card is an expansion card or integrated circuit that provides a computer with the ability to produce sound that can be perceived by the user through a peripheral device like speakers or headphones.
Sound card connections, a sound card has small, rounded 1/8 inches jacks on the back of it for connecting microphone, headphone and speakers and other sound equipment like DA15 game port.
3-131
Sound in or line in (Blue)
Microphone or Mic (Pink)
Sound out or line out (Green)
TV tuner cards and video capture cards.
3-132
A computer is capable of showing TV stations on a monitor by using a TV tuner card. The TV tuner card allows the user to connect a home cable television to the computer. The computer could then display basic cable stations and even digital cable stations on the monitor.
A TV tuner card can even provide a method for recording TV shows on the computer for later viewing.
video capture cards.
I/O card.
3-132
is Often used as a catchall phrase for any expansion, common examples are the serial RS-232 and the parallel ports.
communications adapters.
3-132
communications adapters give a computer the ability to transmit information to other devices that might be too distant to cable up to directly.
Network interface card and modem are the two most popular.
Network interface card ( NIC).
3-132
the NIC is also referred to as Network interface controller and an Ethernet card and network adapter.
It is an expansion card that enables a computer to connect to a network; such as a home network, or the Internet using an Ethernet cable with an RJ-45 connector. wireless NIC does not need to cabled and Cellular card.
Modem
3-134
Short for MODulator/DEModulator, the first Modem known as the Dataphone,
The Modem is a hardware device that enables a computer to send and receive information over telephone lines by converting the digital data used by your computer into an analog signal used on phone lines and then converting it back once received on the other end.
Riser card.
3-134
A riser board is a circuit board that gives a computer motherboard the option for additional expansion cards to be added to the computer. Desktop computer riser boards were used with LPX, NLX (New Low profile Expended) and even some ATX motherboards. LPX motherboards had a riser board slot on the motherboard, NLX motherboards plugged into the riser board,
Device Connector Types.
3-137
computer ports are interface that allow other devices to be connected to a computer and there vary depending on there function, we will do the flowing types of peripheral ports:
D-subminiature
RJ-seris
other types.
D-subminiature.
3-137
DE9 Male serial port. DE9 Female connecter on a serial cable. DB25 Male serial port or connecter on a parallel cable. DB25 Female parallel port or connecter on a serial cable. DA15 Female Game port or MIDI port DA15 Male DE15 Female DE15 Male
RJ-Series Registered jack
3-138
used in telecommunications.
the most common are RJ11 and RJ45.
RJ11 is used with flat cable in telephone hookups.
RJ45 connector are larger and are used for Ethernet.
USB universal serial bus
3-140
flat ports, they replace DR9M serial port.
USB 1.x is an external bus standard that supports data transfer rates of 12 Mbps and is capable of supporting up to 127 peripheral devices.
USB 2.0 support Data rates as high as 480Mbps that is ( 60 MBps).
USB 3.0 support Data 5Gbps.
IEEE 1394(FireWire)
3-141
is a bus that has a bandwidth of 400-800 Mbps, can handle up to 63 units on the same bus, and is hot swappable. Users more familiar with USB can relate FireWire to USB as it has many similarities. Like USB, FireWire has dozens of different devices such as removable drives and cameras.
A6-pin FireWire port on PC and A4-pin FireWire port on laptop.
Infrared: it is a slow Technic that no one use any more.
3-142
Infrared port (IR) is a small port on the computer that allows data to be sent and received using electromagnetic radiation in the infrared band . Infrared is a method of transferring data without the use of wires. A common example of an infrared (Ir) device is a TV remote. However, infrared is also used with computers with devices such as a cordless keyboard or mouse within sort distance.
Audio/Video jack
3-143
RCA jack ( female), RCA (jack ( male) they used to be used only for audio as line in, line out, microphone, and now they are even used for video.
PS/2
3-144
Often referred to as the mouse port or keyboard port, the PS/2 port was developed by IBM and is used to connect a computer mouse or keyboard to an IBM compatible computer. The PS/2 port is a mini DIN 6 plug that contains six pins and is still found on all IBM compatible computers today, however, is starting to be replaced by USB.
centronics connecter
3-144
we call it The parallel port also, it was primarily used in parallel printer connectionist is most often found on peripherals not on computer themselves.
Floppy connecters and parallel ATA connectors
3-146
The floppy channel, FDD header, or floppy connection is where the floppy drive connects to the computer motherboard. the standard PC floppy drive connector contains 34-pin holes.
Short for Advanced Technology Attachment, used to connect such devices as hard drives, CD-ROM drives, and other disk drives. the PATA connecter has 40 pins.
if the headers of the PATA are blue they represent the UDMA that has 80 wire ribbon cable that allow increased transfer of DATA by reducing crosstalk in the parallel signal.
The classic game port
3-150
or joystick port, the game control adapter has 15-pin
this port has been largely replaced by game devices that connect using USB and the 15-pin connector is no longer used.
parallel interfaces
3-152
A computer connection capable of transmitting more than one bit of information at the same time. A good example of a parallel interface is the parallel port.
There are three major specifications of parallel ports: —
-Standard
-bidirectional
-Enhanced
Standard parallel port
3-152
transmits data in one direction, out of the computer. For example, the parallel port allow the computer to send data to a printer but do not allow that printer to communicate back to the computer.
It can transmit data at only 150 KBps.
It also had maximum transmission distance of 10 feet.
bidirectional parallel port
3-152
is capable of transmitting data in both directions, but not at the same time. it is capable of interfacing with external devices like CD-ROM, tape drives,
