Connectivity

3. Types Unshielded Twisted Pair (UTP) Cable
Shielded Twisted Pair (STP) Cable
Coaxial Cable
Fiber Optic Cable
Wireless LANs

4. Unshielded Twisted Pair
Four pairs of wires
Twisting helps to eliminate interference
More twists less interference
More twists = higher cost
Six categories 1
1 Mbps
Voice Only (Telephone Wire) 2
4 Mbps
LocalTalk & Telephone (Rarely used) 3
16 Mbps
10BaseT Ethernet 4
20 Mbps
Token Ring (Rarely used) 5
100 Mbps (2 pair)
100BaseT Ethernet
1000 Mbps (4 pair)
Gigabit Ethernet 5e
1,000 Mbps 6
10,000 Mbps

5. Shielded Twisted Pair Individual pairs and complete wire shielded
Reduces interference
Extends distance allowed between connections
Both UTP and STP use RJ-45 connectors
