|
Which of these are correct?
|
|
The APPLICATION layer encodes/decodes the message in a form that is understood by the sender and the recipient.
|
|
|
Transport layer-breaks down the message into small chunks (packets). Each packet is given a packet number and the total number of packets.
|
|
|
Network layer-adds the sender’s IP address and that of the recipient. The network then knows where to send the message, and where it came from.
|
|
|
Data link layer-enables the transfer of packets between nodes on a network, and between one network and another.
|
|
|
MAC addressing is used by the Network/Internet layer.

Explanation:
Detailed explanation-1: -Layer 3 (Network): This layer determines how data is sent to the receiving device. It’s responsible for packet forwarding, routing, and addressing. Layer 2 (Data Link): Translates binary (or BITs) into signals and allows upper layers to access media.
Detailed explanation-2: -Transport The fourth layer of the OSI model ensures complete and reliable delivery of data packets. The transport layer provides mechanisms such as error control, flow control, and congestion control to keep track of the data packets, check for errors and duplication, and resend the information that fails delivery.
