Transmitting Bits

Fiber Optic

SONET (Synchronous Optical Network)

fiber optics in tramsmitters, LAN & WAN

cladding/core: both effect the way how light travels through a fiber optic cable

transmitting information impulsing on a piece of fiber

Radio Basics

electromagnetic wave frequency are called radio waves

electromagnetic radiation

Wireless WANs & LANs

The difference between a Wireless WAN and a Wireless LAN is WAN is the process of using any wireless connection that is world wide instead of in a local area like a LAN would be used.

Ethernet LANs

pin positions, RJ-45 conncectors

UTP (Unshielded Twisted-Pair)

protocal used in networking that rates over 1 gigabit

bit rate

encoding scheme; manchester encoding

the number of bits sents over the rate each second

bit rate/time

electrical circuit

voltage, amplitude, frequency, phase

Electrical currents are the amount of electricity that flows past a single point on the circuit.

loop of material in which electricity can flow
