Networking Theory
Computer Networking:- Two or more nodes that are connected using some type of physical medium exchanging information using a common networking protocol.
Node:- Computer, Peripheral, or Networking Device
Medium:- Copper Cable, Fiber Optic, Wireless Radio
Protocol:- LAN: Ethernet, Taken Ring, FDDI, 802.11 wireless
WAN: IP(HTTP), PPP, ATM, ISDN, FrameRelay
Serial:- one-bit at a time
Parallal:- more than one-bit at a time
Why Network?

Portability(Centralized File Storage, E-mail)
Reduce Costs
Direction Of Data Communication:
Simplex- One Way
Duplex- Two way (simultanous)
Half-Duplex- Two way (one at a time)
CAT/5/5e/6 UTP or STP:
Connector: RJ-45
Transmission: 100mbps-1000mbps
Distance: 100 feet
802.11 Wireless:
Transmission: 11mbps-400mbps
Distance: 100 feet
Fibre Optic:
Connector: Various
Transmission: 100mbps-1000Gbps+
Distance: 2-20km+
And a lot more!!!
