What is tcpip header and trailer?
An Ethernet frame has a 14 byte header, a data section, and a 4 byte trailer 14 byte header consist of destination address, source address and type The trailer is for CRC (Cyclic redundancy Check) An Ethernet frame can contain an IP and TCP PDU. IP header most important parts consists of (Version,IHL, Total length,Protocol, source and destination address) In details (Version,Header length,Differentiated services field, total Length, Identification, Flags, fragment offset, Time to live, protocol, header checksum, source and destination address). TCP header most important parts consists of (Source port, Destination port and header Length) In details (Source Port, Destination Port, Sequence number, Acknowledgment number, Header length,Flags,Window and check sum). The details of the IP and TCP header have been taken from a Network protocol Analyzer Wireshark on my own pc.

Why is it that a server needs a fixed port number but client process can be given any random port number?
The client process needs a temporary port number. It tells the server to which port to reply (the TCP or UDP header includes information about the source and the destination port). The client, on the other hand, doesn't know in advance what port the server uses - unless the server uses a standard port number.The client process needs a temporary port number.

How do extended access control list differ from standard access control list?
Standard Access Control Lists (ACLs) only allows you to permit or deny source addresses. You can not block based on protocol, port, or destination. Extended ACLS allow you to block traffic based on source address, destination address, source port, destination port, and protocol.
