CHAPTER 8: WIRED LANs (ETHERNET)

1. Fast Ethernet

1.1. Designed for copper-based twisted pair

1.2. The length was restricted to 100 meters supported different cable categories

1.3. MAC Sublayer

1.3.1. Access method is half duplex with CSMA/CD

1.3.2. Autonegotiation that allows two device to negotiate the mode or dara rate of operation

1.4. Physical Layer

1.4.1. Uses star topology

1.4.2. Categorized as either two-wire(CAT 5 UTP or Fiber optic) or four-wire (CAT 3 UTP)

2. Gigabit Ethernet

2.1. Compatible with standard or fast ethernet

2.2. Use the same 48-bit address

2.3. MAC Sublayer

2.3.1. Half-duplex using CSMA/CD

2.3.2. Full-duplex without CSMA/CD

2.4. Physical Layer

2.4.1. Star topology

2.4.2. Categorized as

2.4.2.1. Two-wire (fibre-optic cable)

2.4.2.2. Four-wire(CAT 5 twisted-pair cable)

3. Ten-Gigabit Ethernet

3.1. Full-duplex point-to-point links which CSMA/CD is not used.

3.2. Connected using network switches

3.3. Shared-medium CSMA/CD

3.4. Physical Layer

3.4.1. Using fibre-optic cable over long distance.

4. ISMA HAZIQ 2016696146

5. IEEE Standard

5.1. IEEE 802 Dealing with local area networks and metropolitan networks

5.2. Restricted to network carrying variable-size packets

5.3. Specifying function of physical layer and data link layer

6. Standard Ethernet

6.1. 10Best-T (10Mbps)

6.2. Approximately 100 meters per segment over unshielded twisted pair cables

6.3. Robustness (high reliability)

6.4. Transmitted using the CSMA/CD protocol

6.5. CAT-5 cable which is Category-5

6.6. Twisted pair wiring

6.7. Data link layer

6.7.1. Logical Link Control (LLC)

6.7.1.1. Flow control

6.7.1.2. Error control

6.7.1.3. Framing duties

6.7.2. Media Access Control (MAC)

6.7.2.1. Responsible for the operation of CSMA/CD and framing.
