<h3>what is a computer network?</h3>
- A group of computers sharing resources that are available on or offered by network nodes is known as a computer network.
- Over digital links, the computers communicate with one another using standard communication protocols.
- These connections are made up of telecommunication network technologies, which are based on physically wired, optical, and wireless radio-frequency means and may be set up in a number of different network topologies.
- Personal computers, servers, networking equipment, and other specialized or general-purpose hosts can all function as nodes in a computer network.
- They can have hostnames and are identifiable by network addresses.
- After being assigned, hostnames act as recognizable labels for the nodes and are seldom updated.
- Network addresses are used by communication protocols like the Internet Protocol to locate and identify the nodes.

In a Transmission Control Protocol (TCP) header next Expected segment is provided by Acknowledgment Number
Explanation:
- TCP is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in the Internet Protocol.
- The fields in TCP Segment Header are Source Port, Destination Port, Sequence Number, Acknowledgement Number, Header Length, Flags, Window Size, TCP Checksum and Urgent Pointer.
- The Acknowledgment Number is a 32 Bit number field which indicates the next sequence number that the sending device is expecting from the other device.
- The SYN packets consume one sequence number, so actual data will begin at ISN+1. The sequence number is the byte number of the first byte of data in the TCP packet sent.
- If the acknowledgment flag is set in the flags field, the acknowledgment number field holds the sequence number of the next byte that the receiver expects.
