Q: Which is the first segment that computer 1 has to construct if it’s a TCP connection?
- IP datagram
- handshake
- TCP segment
- Ethernet frame
Explanation: Computer 1 is required to construct the TCP segment as the first segment if the connection is a TCP connection. The actual data that is going to be communicated is included inside the TCP segment, in addition to information that is contained within the TCP header. This information includes the source and destination ports, sequence numbers, acknowledgment numbers, and a variety of control flags. After that, the transport control protocol (TCP) section is encased into an Internet Protocol (IP) datagram, which is subsequently encapsulated into an Ethernet frame for transmission across the network.
