14 Questions
What is a TCP segment made up of?
A TCP header and a data section.
What information is contained in the TCP header?
Source and destination port fields, sequence number, acknowledgment number, data offset field, and six TCP control flags
What fields are included in the TCP header?
Source and destination port fields, sequence number, acknowledgment number, data offset field, and six TCP control flags.
What is the purpose of the TCP window?
To specify the range of sequence numbers that might be sent before an acknowledgment is required
What does the TCP window specify?
The range of sequence numbers that might be sent before an acknowledgment is required
Why is TCP considered to be super reliant on acknowledgments?
Because it is a reliable protocol
Why is TCP super reliant on acknowledgments?
To ensure data reliability and integrity.
What is the purpose of the TCP checksum?
To ensure the segment has not been corrupted during transmission
What does the TCP checksum verify?
The entire segment.
What is the purpose of the urgent pointer field in the TCP header?
To point out particular segments that might be more important than others
What is the purpose of the urgent pointer field?
To point out particular segments that might be more important than others.
What is the purpose of padding in a TCP segment?
To ensure that the data payload section begins at the expected location
What is the purpose of padding in a TCP segment?
To ensure that the data payload section begins at the expected location.
What encapsulates a TCP segment?
An Ethernet frame encapsulates an IP datagram, and an IP datagram encapsulates a TCP segment
Study Notes
- TCP segment is made up of a TCP header and a data section.
- TCP header contains source and destination port fields, sequence number, acknowledgment number, data offset field, and six TCP control flags.
- TCP window specifies the range of sequence numbers that might be sent before an acknowledgment is required.
- TCP is a protocol that's super reliant on acknowledgments.
- TCP checksum is calculated across the entire segment and is compared with the checksum in the header.
- The urgent pointer field is used in conjunction with one of the TCP control flags to point out particular segments that might be more important than others.
- The options field is rarely used in the real world.
- Padding is a sequence of zeros to ensure that the data payload section begins at the expected location.
- Ethernet frame encapsulates an IP datagram, and an IP datagram encapsulates a TCP segment.
- A TCP segment is required to keep lots of outgoing connections separate.
