- 20 bytes
- 32 bytes
- 64 bytes
- 60 bytes
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
The TCP header contains control information required for reliable communication.
The header size can vary depending on whether options are present.
Step 1: Minimum TCP header size.
Without options, \[ \text{TCP Header Size} = 20 \text{ bytes} \]
Step 2: Maximum TCP header size.
The Header Length field is 4 bits. Maximum value: \[ 15 \] Each unit represents 4 bytes. Therefore, \[ 15 \times 4 = 60 \text{ bytes} \]
Step 3: Choose the answer.
Hence the maximum TCP header size is \[ \boxed{60\text{ bytes}} \]
Step 1: Minimum TCP header size.
Without options, \[ \text{TCP Header Size} = 20 \text{ bytes} \]
Step 2: Maximum TCP header size.
The Header Length field is 4 bits. Maximum value: \[ 15 \] Each unit represents 4 bytes. Therefore, \[ 15 \times 4 = 60 \text{ bytes} \]
Step 3: Choose the answer.
Hence the maximum TCP header size is \[ \boxed{60\text{ bytes}} \]
