WHAT ARE THE DIFFERENCE BETWEEN STRAIGHT THROUGH AND CROSS OVER CABLE?


           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 uses the T568B wiring standard. The internal wiring of Ethernet crossover cables reverses the transmit and receive signals. It is most often used to connect two devices of the same type: e.g. two computers (via network interface controller) or two switches to each other.

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...

 Network devices -  " network "  device  is a component that makes up the  network  infrastructure such as modems, routers and switches. A "networked"  device  on the other hand refers to equipment that connects to a  network . Hub - is a simple device that directs data packets to all devices connected to it. S erves simply as a conduit for the data, enabling it to go from one device to another.  Switch - are the connectivity point of a wired network. Devices are connected via twisted - pair  cabling, one cable for each device. Router -  are completely different devices. I s hardware device designed to receive, analyze and move incoming packets to another network. Bridge - is used to divide larger network into smaller sections. It is located between two physical network segments and manages the flow of data between the two.  Network Interface Card - is a device that enables com...

WHAT IS A COMPUTER NETWORK? COMPUTER NETWORK - is a collection of networks . I s a set of  computers  connected together for the purpose of sharing resources. The most common resource shared today is connection to the  Internet . Other shared resources can include a printer or a file server.                      ADVANTAGES AND DISADVANTAGES  ADVANTAGES OF COMPUTER NETWORK                                                         Reduced Co st  Everyone in your home or office can share a single printer and a single high-speed internet connection at the same time.                                                    Increased Eff...
