The Ethernet network constructed from cables made of twisted pairs (the 'T' part in the name) of copper wires conforming to the Category-3 standard. It is stated to have a bandwidth of 10 Mbps (the 10Base part in the name). If Category-5 type cables were used instead, the network would support the futuristic 10-Gigabit (10 Gbps) Ethernet standard.

The Fast-Ethernet network constructed from cables made of twisted pairs of copper wires conforming to the Category-5 standard. It is stated to support a bandwidth of 100 Mbps provided the network devices also have the 100 Mbps capability.

The capacity of a network link for carrying data. This is usually measured in bits per second. E.g., 56 Kbps, 128 Kbps, 10 Mbps. (Kbps = kilobits per sec.; Mbps = Megabits per sec.)

Cable drop
A LAN An Ethernet cable-run between two wall jacks. Usually, wires at each end are ordered according to 10Base-T (Straight-through) Ethernet standard and connected to the back of the RJ45 jacks.

Category-5 cable
Cables made of four twisted pairs of wires conforming to this standard. This is similar to Category-3 cable but is manufactured to stricter standards.

Clear Channel
A digital communication channel guaranteed to be 100% error free. ISDN channels are said to be clear channels that deliver pure 64 Kbps bandwidth. When a connection is completely error free, it eliminates back and forth requests for re-sends as it happens on connections over analog lines, which reduces the effective bandwidth.

Crossover cable
A special type of Ethernet cable with two different patterns of pin-outs at each end of the cable.

Installation Kits
Kits made up of wall socket assemblies, Ethernet cables, punch-down tools, NICs, pre-programmed routers etc. specially assembled for pre-planned network installations.

A LAN Local Area Network: A collection of computers, and other network devices in one physical location interconnected as one communication unit.

Network hub
A simple device that helps to connect multiple computers on a star topology computer network. Typically, it has several RJ45 jacks (ports) that accept cable plugs connecting the computers, routers etc. together.

Network Interface
The interface that is used to connect the computer to the network. For 10Base-T, there are several possible interfaces. They all have a RJ45 type modular jacks to accept cable plugs (much like a telephone plug) found on the end of an Ethernet cable.

Network Switch
Switches are similar to hubs but have varying additional capabilities. For instance, some can be programmed to logically partition physical networks or direct file server access privilege according to workgroups.

Patch cord
An Ethernet cable, usually, straight-through type, that has RJ45 connectors at its ends.

RJ45 jack
Registered Jack #45: A modular jack similar to a telephone jack but wider. It has eight conductor locations for an eight-wire cable such as an Ethernet cable.

A device that routes or directs network data packets in and out of a network. They also typically run firewalls that control traffic of packets according to programmed rules.

A computer doing one or more specialized service such as holding data files for common access, serving up web pages, centrally running applications for client computers or giving access to printers attached to it.

Straight-through cable
An Ethernet cable with both ends of the cable having the same standard pin-out pattern.

Telephone Consultation
Telephone consultation is provided as part of a planned project that usually include help with installation of network interfaces that we supply as part of an installation kit.

Virtual private network: A secure, logical network combining geographically separate networks constructed by transmitting encrypted data packets over the public network (e.g. the Internet).
