Andrey Borsch NT1310 Unit 4 Exercise 1 4-18-14 Cabling - Definitions Horizontal Cable - The cabling between and including the telecommunications outlet and the horizontal cross-connect. Horizontal cabling is considered the permanent portion of a link; may also be called horizontal wiring. Backbone Cable - The physical/electrical interconnections between telecommunications rooms and equipment rooms Patch Cord - Any flexible piece of cable that connects one network device to the main cable run or to a patch panel that in turn connects to the main cable run. Used for interconnecting circuits on a patch panel or cross-connect. Patch cables are short distance, usually have connectors preinstalled on both ends, are used to connect equipment, and are generally between 3 and 6 meters long.
Instead, it uses radio or light waves for transmission purposes. Wireless network gives the added value of being able to connect handheld devices and portable computers wirelessly. This is worth considering in a case where structure, office layout etc. changes frequently. There are two common wireless network connection types namely fixed wire replacement and ad hoc networks.
Unit 3 Exercise 1: Specifications – Definitions by: Timothy Robertson 1. Application- The technology that will take advantage of cabling systems. Applications include telephone systems, Ethernet, token ring, ATM, etc. 2. Unshielded Twisted Pair- A cable used in computer networking that consists of two shielded wires twisted around each other.
