---|---|---|---|---|
What is 10BaseT?
Ethernet LAN designed to run on twisted pair
cabling. Runs at 10 megabits per second. The maximum length for the cabling between the NIC and the switch(or hub, repeater, etc.) is 100 meters. It uses baseband signaling. |
What is hybrid?
A network topology that combines features from
multiple other topologies, such as the star-bus topology. |
What is CRC (cyclic redundancy check)?
Very accurate mathematical method used to check for errors in long streams of transmitted data.
|
What is a server?
Computer that shares its resources, such as printers and files, with other computers on a network. Example: network file system server that shares its disk space with a workstation that does not have a disk drive of its own.
|
What is RJ-11?
a connector for four-wire UTP; usually found in telephone connections.
|
What is bandwidth?
The capacity of a network to transmit a given amount of data during a given period
|
What is a LAN?
Group of PCs connected via cabling, radio, or infrared that use this connectivity to share resources such as printers and mass storage
|
What is 1000BaseT?
Gigabit Ethernet on UTP
|
What is a NIC (network interface card or controller)?
Expansion card or motherboard interface that enables a PC to connect to a network via a network cable.
|
What is a router?
Device connecting separate networks; forwards a
packet from one network to another based on the network address for the protocol being used. |
What is Ethernet?
Name coined by Xerox for the first standard of
network cabling and protocols. Based on a bus topology. |
What is mesh topology?
Network topology where each computer
has a dedicated line to every other computer, most often used in wireless networks. |
What is a default gateway?
In a TCP/IP network, the nearest router
to a particular host. This router’s IP address is part of the necessary TCP/IP configuration for communicating with multiple networks using IP. |
What is a wide area network (WAN)?
A widespread group of computers connected using long-distance technologies.
|
What is topology?
The way computers connect to each other in a
network. |
What is broadcast?
A network transmission addressed for every
node on the network. |
What is a bus?
Series of wires connecting two or more separate electronic devices, enabling those devices to communicate. Also, a network topology where computers all connect to a main line.
|
What is a frame?
A data unit transferred across a network. Consists of several parts, such as the sending and receiving MAC addresses, the data being sent, and the frame check sequence.
|
What is a star bus?
A hybrid network topology where the computers
all connect to a central bus—a switch—but otherwise take the form of a star topology |
What is a subnet mask?
Value used in TCP/IP settings to divide the
IP address of a host into its component parts: network ID and host ID. |
What is MAC (media access control) address?
Unique 48-bit
address assigned to each network card. IEEE assigns blocks of possible addresses to various NIC manufacturers to help ensure that the address is always unique. The Data Link layer of the OSI model uses this for locating machines. |
What is 100BaseT
Ethernet cabling system designed to run at 100
megabits per second on twisted pair cabling. It uses baseband signaling. |
What is DNS (domain name service)?
TCP/IP name resolution system that translates a host name into an IP address?
|
What is a network protocol?
Software that takes the incoming data received by the network card, keeps it organized, sends it to the application that needs it, and then takes outgoing data from the application and hands it to the NIC to be sent out over the network.
|
What is a web server?
A computer that stores and shares the files
that make up Web sites |
