Chapter 3 Flashcards
(25 cards)
Define Expansion card
A circuit board you install into a computer to increase its capabilities. p.129
What are the four most common types of expansion cards?
Video, Multimedia, I/O and communications p.129
What is the preferred expansion slot for video cards?
PCIe p. 130
What is the name of the expansion card that allows you to connect a broadcast signal and display its output on the monitor?
TV tuner card. p.132
What does a video capture card do?
Used to save a video stream to the computer for later manipulation and sharing. p.132
How do modems communicate information differently than Network Adapters?
Modems transmit information over the PSTN (telephone company). Network adapters are used generally in the administrative domain of the home and allow users to transmit information worldwide to other devices that may be too distant to cable up to directly. p.132
What does a Network Interface Card do?
Allows a computer to connect to a network so that it can communicate with other computers on that network. p.132
What does the Network Interface Controller card do?
It translates the data from the parallel data stream used inside the computer into the serial data stream that makes up the frames used on the network. It has a connector for the type of expansion bus on the motherboard (PCI, PCIe and so on). In addition to installing the NIC you must also install drivers for the NIC n order for the computer to use the adapter to access the network. p.132
Define Port
A generic name for any connector on a computer or peripheral into which a cable can be plugged. p.136
What is the speed of USB 3.0
5Gbpd
What are two common Radio Frequency (RF) technologies computers use to send and recieve data. Note infered is different. it uses electro magnetic radiation.
Blue Tooth and WiFi p.142
What is a PS/2 port for?
a mouse
Define Interface
A method of connecting two disimlar items together.
Identify some common interfaces.
Drive Interfaces, SCSI, Parallel, Serial, USB IEE 1394 Firewire, RJ-45, Audio, and PS/2.
What do blue PATA headers indcate
They represent PATA interfaces that employ the ATA 5 or higher version of Ultra DMA technology. They require 80 wire ribbons that allow increased transfer rates by reducing crosstalk in a parallel signal. p. 147
What are the most common types of ports?
USB, Fire Wire/IEEE1394,eSATA,video, Ethernet, digital/analog sound in/out, and PS/2.p.149
What are some of the most common interfaces?
DC power n, Analog modem RJ-11, Ethernet NC RJ-45, S-Video out, DVI-D (Dual Link) Out SVGA out, Parallel (on top), Standard Serial, Mouse (on top), Keyboard, USB, S/PDF(out) (See picture on page 150)
What are three main types of Serial Interfaces.
Standard Serial (RS-232), USB, and FireWIre (IEEE 1394) p.155
What is a null modem serial cable used for?
To hook two computers together without a modem. p.155
what is the maximum number of hubs between the system and any component?
5 p.159
What is an advantage of IEEE 1394 (FireWire)?
The production of 45 W of power allows for larger devices to be powered by the FireWire interface so you don’t need external power. (can also do on eithernet). It has a high data-transfer rate it s a universal high speed data interface for things like hard drives optical drives and digital video editing equipment. Firewire 400 allows 1023 buses each supporting 63 devices that can communicate directly with one another instead of having to go through a host like USB is required. p.162
What are two video display interfaces?
DVI and HDMI p. 166
What are three types of DVI connectors?
DVI-A, Analog only, DVI-D Digital only, and DVI-I which is a combination. p.167
Are HDMI nterfaces compatible wth DVI-D or DVI-I interfaces through proper adaptors?
Yes, but HDMI’s audio and remote-control pass through features are lost. p.168
