Final answer:
The control field in a TCP segment has 6 bits, allowing for 64 different combinations of bits. Some commonly used combinations include 000000, 000001, and 000010.
Step-by-step explanation:
The control field in a TCP segment consists of 6 bits. With 6 bits, we can have 64 different combinations of bits. Here are some commonly used combinations:
- 000000: This combination is used for a TCP segment with no control flags set.
- 000001: This combination is used for a TCP segment with only the urgent pointer flag set.
- 000010: This combination is used for a TCP segment with only the acknowledgment flag set.
