The minimum header size will be 32 bits.
- TCP / IP is the Transmission Control Protocol, which is a series of networking protocols that allows two or more computers to communicate with each other.
- A port number is a 16-bit unsigned integer ranging from 0 to 65535. Port number 0 is reserved for TCP and thus can not be used while the source port is optional for UDP .
- In the given question, the minimum header size will be 2 × 16 bits which is 32 bits to contain the sending and receiving port address.
