What component of a network card can have its settings programmed by a network administrator using a software program? a. EEPROM b. jumper c. DIP switch d. Plug-and-play e. Testing diagnostics: a.
An EEPROM is a read-only memory chip that contains NIC settings that can be modified by a special software utility.
What network testing component can truly check the electrical output on the port of a network interface card? a. software loopback b. hardware loopback c. vendor-suplied diagnostics d. plug and play e. EEPROM: b.
A hardware loopback connects to the back of the network card where a cable would normally be attached.
What two components talk to each other to auto-configure settings through plug-and-play technology? a. DIP switches b. hardware loopback c. NIC BIOS d. EEPROM e. Motherboard BIOS: c and e
The plug-n-play BIOS on the motherboard and the network interface card talk to each other to determine communication settings.
What is the difference between an EPROM and an EEPROM? a. An EPROM uses UV light to erase communication settings on a NIC, whereas an EEPROM does not. b. An EEPROM uses UV light to erase communications on a NIC, while an EPROM does: a.
An EPROM uses UV light to erase communications on a NIC, whereas an EEPROM does not.
What type of network uses a MAU? a. UNIX b. Ethernet c. IP d. IPX e. Token Ring: e.
Token Ring networks use MAUs (Multistation Access Unit), which operate on the Physical layer.
Which type of hub does not require power? a. Active b. Passive c. Intelligent d. Switched e. Unswitched: b.
A passive hub does not use electricity.
Two lengths of cable need to be connected to connect two different buildings. Each cable is at its maximum length. What device is best suited to regenerate the signal from the first cable to the second? a. transceiver b. repeater c.: b.
A repeater regenerates electrical signals to extend the distance network cables can reach.
Which device is used to connect a DIX port on a network card to a thicknet cable? a. transceiver b. router c. hub d. MAU e. switch: a.
Transceivers are used to directly connect a NIC without the proper port to the network cable. One side of the transceiver is a DIX port; the other side cnsists of the proper port, or Vampire Tap prongs. The Vampire Tap cuts through the outer casing of a netowrk cble and establishes a connection with the core.
Collection of instructions on a read-only chip that allows hardware and software to talk to each other.: BIOS
(Basic Input/Output System)
Allows a setting to be changed on a card by flipping a tiny switch; preferable to jumpers.: DIP switch
(Dual In-line Package)
Uses ultraviolet light to erase settings on expansion cards. Software is then used to configure new settings.: EPROM
(Erasable Programmable Read-Only Memory)
Allows a software utility to erase settings and configure an expansion card.: EEPROM
(Electronically Erasable Programmable Read-Only Memory)
Component that slips over two pins to configure expansion cards: Jumper
Communication hardware connecting computers to a network: NIC
(Network Interface Card)
Technology that automatically configures IRQs, base memory and I/O memory.: Plug-and-play
Multi-port device that regenerates a signal allowing cables to run the full length of their specifications: Hub
Directs communications to the port that serves the specific recipient of the message. Operates on the Data Link layer.: Switching hub
Hub that works in Token Ring networks: MAU
(multistation access unit)
Device that regenerates electrical signal coming from one port and sending to another port. Enables cable length to be extended.: repeater
Device used to connect a network card with a coaxial cable network. Convert box that connects to the DIX port on a NIC and the coaxial cable on the other end.: transceiver
_____ devices are electrically powered to regenerate network signal. Allows additional cables to be added without initial cable being part of the maximum cable length.: Active
Multi-pinned connection on the back of a NIC that tranceiver connects to.: DIX
(Digital, Intel, and Xerox)
port
Another name for DIX port: AUI
(attachment unit interface)
port
Device that operates on the Physical layer to distribute inbound network signals to many outbound connections: Hub
Another name for AUI port: DIX
(Digital, Intel, and Xerox)
port
Term for a device that does not have an electrical signal, using electricity that comes from network cables. Does not extend the distance a signal can travel along cable.: passive
Special purpose device used to attach multiple computers to a Token Ring network.: MAU
(multistation access unit)
Powered device that regenerates an electrical signal, allowing two sections of a network by using multiple cables.: repeater
Device that operates on the Data Link layer and directs packets using MAC addresses.: switch
Component of a NIC that is responsible for transmission and reception. Can be built-in or added.: transceiver
