Which of the following is/are true about windowing in TCP/IP?

  1. For a window size of 3 the ack4 signal says send the 4th packet.

  2. For a window size of three, the packets will be sent in three different routes and acknowledgment is expected for each.

  3. For a window size of 3 the acknowledgement is always ack3 to notify THAT the 3 packets were received.

  4. None of the above.


Correct Option: A
  1. PVC

  2. LCI

  3. DLCI

  4. ASIC


Correct Option: C
Explanation:

To solve this question, the user needs to have a basic understanding of computer networking and the different components that make up a network. Specifically, the user should be familiar with Ethernet and Frame Relay, as well as the acronyms associated with these technologies.

Explanation of each option:

A. PVC: PVC stands for Permanent Virtual Circuit, which is a type of connection used in Frame Relay networks. This option is correct because PVC is the equivalent of MAC in Ethernet. Both PVC and MAC provide a unique identifier for each device on the network.

B. LCI: LCI stands for Link Connection Identifier, which is a term used in ATM (Asynchronous Transfer Mode) networks. This option is incorrect because it is not related to Frame Relay.

C. DLCI: DLCI stands for Data Link Connection Identifier, which is a term used in Frame Relay networks. This option is correct because DLCI is the equivalent of MAC in Ethernet. Both DLCI and MAC provide a unique identifier for each device on the network.

D. ASIC: ASIC stands for Application-Specific Integrated Circuit, which is a type of integrated circuit designed for a specific application. This option is incorrect because it is not related to either Ethernet or Frame Relay.

Therefore, the correct answer is:

The Answer is: C. DLCI

  1. A channel service unit/digital service unit (CSU/DSU)

  2. An Ethernet card

  3. DTE
