Week 5 Introduction To Networking

Computer Network
-connecting to a computer with other computers or other devices to enables them to communicate together with each other.
-it can be : 1. devices equipment
                 2. transmission media to send/control data/signals
                 3.communication devices to transmit/send data from source to destination
-In the world of computer, NETWORKING is the practice of linking two or more computing devices together for the purpose of SHARING DATA.

Types Of Network
-Local -Area Networks(LAN)
-Wide-Area Networks(WAN)
-Metropolitan Area Network(MAN)
-Personal Area Network(PAN)



Network Component

                                

Network are categories into 3 properties:

*Topology--->geometric arrangement of the network

*Protocol--->common set of rules and signals    

*Architecture---> Peer -to- peer, and client/server

Topology 

4 main types of network structure are :

1. Bus Network Structure

2.Star Network Structure

3Ring Network Structure

4.Hybrid Network Structure

Protocol

1.Ethernet Protocol(most common used today!!!!!)

2.Token Ring Protocol

3.Local Talk Protocol

4.Fiber Distributed Data Interface(FDDI)

5.Asynchronous Transfer Mode(ATM)

Architecture

Two major types of network architecture :

*Peer-to-peer

*Client/server

Transmission Media:

Bounded Media--->got cables, for example:twisted pair wire,co-axial cable,fiber optic cables

Unbounded Media--->air or vacuum, for example: AM and FM radio,TV broadcasting,satellite communication, microwave radio, Infrared signals

AM RADIO

"AM Radio" is a rock song by the band Everclear. The song was recorded circa 2000 for Everclear's fourth album Songs from an American Movie, Vol. 1: Learning How to Smile So. The song was released as the second single from Everclear's album Songs from an American Movie, Vol. 1: Learning How to Smile. It spent 10 weeks on the Billboard Bubbling Under Hot 100 Singles chart, and reached #101. The "AM Radio" single was mistaken by many to be the first single from Everclear's fifth album, Songs from an American Movie, Vol. 2: Good Time for a Bad Attitude because the song was released so soon before Everclear's fifth album's release. The song was later used in a television commercial for General Motors in early 2006. 

FM RADIO

FM broadcasting is a broadcasting technology pioneered by Edwin Howard Armstrong which uses frequency modulation (FM) to provide high-fidelity sound over broadcast radio. The term "FM band" describes the "frequency band in which FM is used for broadcasting". This term is slightly misleading, since it equates a modulation method with a range of frequencies.
