9: Packet Tracer Types of cable: Console One piece cable Used for connecting your PC's serial port to the RJ45 console port on most Cisco equipment Typically flat

Copper Straight Through & Cross-over Straight-through cable is the standard config of NW cable Crossover is the same, but with a connector at one end wired differently Key difference is the wiring in the connectors, otherwise they're the same Two computers cannot communicate if connected together by a straight through cable  This is because both will transmit on the transmit channel and so neither will hear anything on the receive channel A crossover cable converts transmit to receive and vice versa at one end of the cable

Fibre Optic NW cable that contains strands of glass fibres inside an insulated casing Designed for long distance and very high bandwidth NW comms Expensive, but increasingly being used instead of copper cables because FO offers more capacity and is less susceptible to electrical interference. Fibre to home (FTTH) instillations are becoming more common as a way to bring ultra high speed internet service to residences

Phone Cable Standard that specifies both a physical connector and how its wired Sometimes the same connector is used by different countries but wired in different ways

Though four wires are typically used in the US phone cabling, only two are necessary for tele-comms. The event that a second line is needed, the other two are used

Coaxial Cable Used by TV and that is common for data comms Taking a round cross-section of the cable you would find a single centre solid wire symmetrically surrounded by a braided or foil conductor Between the centre wire and foil is a insulating dialectric

Serial DCE & DTE A serial cable is used to transfer information between two devices using a serial communication protocol The form of connectors depends on the particular serial port used Devices that communicate over a serial interface are divided into two classes: DTE and DCE Most important difference between the two is that DCE device supplies the clock signal that paces the communications on the bus

Octal Cable Uses a 68-pin connector and breakout cable and provide eight RJ-46 rolled cable asynchronous ports on each 68-pin connector You can connect each RJ-45 cable port to the console or AUX port of a device
