17. NETWORK MEDIA
 The function of the media is to carry a flow of information through a LAN.
A. Wired Media:- A widely adopted family that uses copper and fiber media in local area
network (LAN) technology are collectively known as Ethernet
1. Copper Cable
a. Coaxial Cables
b. Shielded Twisted Pair(STP)
c. Unshielded Twisted Pair
2. Fibre Optic Cable
B. Wireless Media:- use the atmosphere, or space, as the medium.

18. COPPER CABLE
➢ The most common, easiest, quickest, and cheapest form of network
media to install.
➢ The disadvantage of sending data over copper wire is that the further
the signal travels, the weaker it becomes.

19. A. COAXIAL CABLE
➢ It can be run longer distances than Twisted pair Cables.
• Speed: 10-100Mbps
 • Cost: Inexpensive
 • Media and connector size: Medium
 • Maximum cable length: 500m

20. SHIELDED TWISTED PAIR
• Speed: 0-100Mbps
• Cost: Moderate
• Media and connector size: Medium to large
• Maximum cable length: 100m

21. UNSHIELDED TWISTED PAIR
➢ UTP is a four-pair wire medium used in a variety of networks.
➢ Each of the eight copper wires in the UTP cable is covered by insulating material
 Speed: 10-100-1000 Mbps*
 Cost: Least Expensive
 Media and connector size: Small
 Maximum cable length: 100m * (Depending on the quality/category of cable)

22. FIBER OPTIC CABLE
➢ Glass fiber carrying light pulses, each pulse a bit.
➢ Based on the Total Internal Reflection of Light.
➢ High-speed point-to-point transmission 10-100’s Gbps
➢ low error rate:
➢ repeaters spaced far apart
➢ immune to electromagnetic noise
