Transmitting Bits

The transmission of data involves various methods and technologies such as bit rate, fiber optics, and wireless communications. Bit rate denotes the number of bits transmitted per second, while different encoding schemes like Manchester encoding affect how data is sent.

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
