Term
|
Definition
| The degradation of a signal over distance that affects the propogation of waves of waves and signals in electrical circuits,optical fibers,as well as in the air. |
|
|
Term
|
Definition
| A generalized term defining a primary cable or system that connects networks together. |
|
|
Term
|
Definition
| Digital signaling that has only one signal on the cable at a time.The signals are in one of the three states-one,zero or idle. |
|
|
Term
|
Definition
| A type of signaling that sends multiple signals (channels) over the cable at the same time.The best example of broadband signaling is cable television.The zero,one and idle states exist on multiples channels on the cable. |
|
|
Term
|
Definition
| A configuration wherein all computers connect to the network via a central bus cable called a backbone. |
|
|
Term
|
Definition
| A type of cable used in network wiring used in 10Base2 and 10Base5 the cable has a single solid-core of copper surrounded by a plastic sheath and shielded with a copper/tin mesh |
|
|
Term
|
Definition
| Cable used to connect two computers together via NICS without the the use of a hub. |
|
|
Term
|
Definition
| A type of interference that occurs when two LAN cables run close to each other. If one cable is carrying a signal and the other isn't the one carrying a signal will induce a "ghost" signal in the other cable. |
|
|
Term
|
Definition
| A high-speed channel for transmitting data,made of high-purity glass sealed within an opaque tube.faster then conventional copper wire such as coaxial cable. |
|
|
Term
|
Definition
| Describes any device that can send and receieve data simultaneously. |
|
|
Term
|
Definition
| A group of PCs connected together via cabling,radio,or infrared that use this connectivity to share resources such as printers and mass storage. |
|
|
Term
|
Definition
| Mesh topology is not in common in computer networking. With Mesh topology,every workstation has a connection to every other component of the network. |
|
|
Term
|
Definition
| A standard defined by the International Standards Organization to catergorize the process of network communication between computers in terms of "layers". |
|
|
Term
|
Definition
| A central wiring point for multiple devices on a network which contains no electronic circuits.Usually they are in server rooms or located near switches or hubs to provide an easy means of patching over wall jacks or hardwire. |
|
|
Term
|
Definition
| A network topology that connects the computers in a circular fashion.If one computer fails, the entire network fails,so this topology is rarely used. |
|
|
Term
|
Definition
| A modular connection that allows for as many as 4 copper wires.Used primarily in telephone connections. |
|
|
Term
|
Definition
| A modular connection mechanism that allows for as many as 8 copper wires.Used primarily in network interface connections. |
|
|
Term
|
Definition
| A Port on a computer that is typically 9-pins and uses Serial communication.Being phased out by USB. |
|
|
Term
|
Definition
| A cable used to connect a host to a switch or hub.Both ends of the cable use the same wiring pinout. |
|
|
Term
| Unshielded Twisted Pair (UTP) cabling |
|
Definition
| A popular type of cabling for telephone and networks,composed of pairs of wires twisted around each other at specific intervals.The twists serve to reduce interference (also called crosstalk).The more twists,the less interference.The cable has no metallic shielding to protect the wires from external interference,unlike its cousin STP. |
|
|
Term
| Shielded Twist Pair (STP) |
|
Definition
| A popular cabling for networks composed of pairs of wires twisted around each other at specific intervals.The twists serve to reduce interference.The more twists,the less interference.The cable has metallic shielding to protect the wires from external interference.Older Token Ring networks are the only common network technology that uses this cabling. |
|
|
Term
|
Definition
| A technology that allows users on different switch ports to participate in their own network seperate from, but still connected to, the other stations on same or connected switch. |
|
|
Term
|
Definition
| A network that uses the public internet as a backbone for a private interconnection (network) between locations. |
