Question

Please define the following key terms .

1. Contention-based

2. Collision fragment

3. Address Resolution Protocol (ARP)

4. MAC address table

5. Asymmetric switching

6. ARP table

7. ARP cache

8. Default gateway

9. Cyclic redundancy check (CRC)

10. Organizationally Unique Identifier (OUI)

Answer 1

1) Contention based (protocols) are popular for the wireless communication scenarios where multiple user interact over the same channel without any apriori coordination.

2) Collision fragment is typically fewer than 64 bytes length and is generated by a collision or the failure of a network interface.

3) ARP discovers the associated MAC or precisely link layer address corresponding to a given internet layer.

4) MAC address table is similar to a routing table used by an ethernet switch to guide the LAN traffic. It is also called as a Content Addressable Memory (CAM) table.

5) Asymmetric switching introduces flexibility in bandwidth allocation and allows smoother traffic flow for a multi user communication scenario.

6) ARP table keeps record of the correspondence between the IP and MAC addresses for lookup requirements.

7) It is a record of the dynamic ARP entries when and IP address is resolved to its MAC address.

8) Default gateway provides a gate to the packets for which no specific forwarding node has been assigned in the routing table.

9) In a communication network, CRC is an error detection code to identify accidental alteration in raw data.

10) It's a 24 bit number used for the unique identification of an organization/vendor. These have to be purchased from IEEE.

Hope this helps!

PLEASE THUMBS UP!!!!!!!!!!!!!!!
