Application- a system‚ the transmission method of which is supported by telecommunications cabling. Unshielded Twisted-Pair- A cable with multiple pairs of twisted insulated copper conductors bound in a single sheath. Shielded Twisted-Pair- A cable surrounded by a twisted braid‚ foil or both and bound in a single plastic sheath containing balanced twisted-pair conductors that are individually shielded. Fiber-optic Cable- is a cable made up of optical fibers that can transmit large amounts of information

showing various layers Note: Shielding protects transmitted data by absorbing stray electronic signals‚ called noise‚ so that they do not get onto the cable and distort the data. Coaxial cable is more resistant to interference and attenuation than twisted-pair cabling. Attenuation is the loss of signal strength that begins to occur as the signal travels farther along a copper cable. [pic] Types of Coaxial Cable There are two types of coaxial cable: ⢠Thin (thinnet) cable ⢠Thick (thicknet)

propagation speed‚ and propagation time. * A guided medium provides a physical conduit from one device to another. Twisted-pair cable‚ coaxial cable‚ and optical fiber are the most popular types of guided media. Twisted-pair cable consists of two insulated copper wires twisted together. Twisting allows each wire to have approximately the same noise environment. Twisted-pair cable is used in telephone lines for voice and data communications. * Coaxial cable has the following layers (starting

A computer network is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet. Network devices that originate‚ route and terminate the data are called network nodes.[1] Nodes can include hostssuch as servers and personal computers‚ as well as networking hardware. Two devices are said to be networked when a process in one

Network Topologies • LANs and WANs - Geographical coverage • LANs – A single geographical location‚ such as office building‚ school‚ etc – Typically High speed and cheaper. • WANs – Spans more than one geographical location often connecting separated LANs – Slower – Costly hardware‚ routers‚ dedicated leased lines and complicated implementation procedures. 1 Network Topologies • Topology - Physical and logical network layout – Physical – actual layout of the computer cables and other

Application (in terms of cabling infrastructure) : It refers to the intended use of the cabling system being installed. Unshielded Twisted – Pair: It’s a type of cable that consists of several conducting cores twisted together in pairs with no surrounding shield. Shielded Twisted- pair: It’s a type of cable that consists of several conducting cores twisted together in pairs surrounded by a shield inside the jacket. Dark Fiber: Unlit fiber Optics‚ also the name given to fiber optics lines that are available

predominant form of Fast Ethernet‚ and runs over two wire-pairs inside a category 5 or above cable. Like 10BASE-T‚ the active pairs in a standard connection are terminated on pins 1‚ 2‚ 3 and 6. Since a typical category 5 cable contains 4 pairs‚ it can support two 100BASE-TX links with a wiring adaptor. Each network segment can have a maximum cabling distance of 100 metres (328 ft). In its typical configuration‚ 100BASE-TX uses one pair of twisted wires in each direction‚ providing 100 Mbit/s of throughput
