WHAT ARE THE TYPES OF CABLES? Twisted Pair Cable     - STP   - UTP Coaxial Cable Fiber-Optic Cable Cables -  a thick rope of wire or nonmetallic fiber, typically used for construction, mooring ships, and towing vehicles. A n insulated wire or wires having a protective casing and used for transmitting electricity or telecommunication signals. TWISTED PAIR CABLE   cabling is a type of wiring in which two conductors of a single  circuit  are twisted together for the purposes of improving  electromagnetic compatibility .I s a type of cable made by putting two separate insulated wires together in a twisted pattern and running them parallel to each other.         STP ( Shielded Twisted Pair ) able was originally designed by IBM for token ring networks that include two individual wires covered with a foil shielding, which prevents electromagnetic interference, thereby transporting data...

WHAT IS A NETWORK OR IP ADDRESS? Network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data. An excellent example of a network is the  Internet , which connects millions of people all over the world. To the right is an example image of a home network with multiple computers and other  network devices  all connected. What is a Network or IP Address? A Network or An  Internet Protocol address  ( IP address ) is a numerical label assigned to each device connected to a  computer network  that uses the  Internet Protocol  for communication.An IP address serves two main functions: host or network interface  identification  and location  addressing . Internet Protocol version 4  (IPv4) defines an IP address as a  32-bit  number. However, because of the growth of the Internet and the  deple...

           DIFFERENCE BETWEEN STRAIGHT THROUGH AND CROSS-OVER CABLE STRAIGHT THROUGH CABLE is a type of twisted pair cable that is used in local area networks to connect a computer to a network hub such as a router. This type of cable is also sometimes called a patch cable and is an alternative to wireless connections where one or more computers access a router through a wireless signal. On a straight through cable, the wired pins match. Straight through cable use one wiring standard: both ends use T568A wiring standard or both ends use T568B wiring standard. The following figure shows a straight through cable of which both ends are wired as the T568B standard. CROSS - OVER CABLE is a type of Ethernet cable used to connect computing devices together directly. Unlike straight through cable, the RJ45 crossover cable uses two different wiring standards: one end uses the T568A wiring standard, and the other end use...
