Computers and Technology
1 answer:
Papessa [141]3 years ago
3 0

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.

{

   *max_ptr=*min_ptr=x[0];

   for(int i=1;i<npts;i++)

   {

       if(x[i]>*max_ptr)        //this will put max value in  max_ptr

           *max_ptr=x[i];

       if(x[i]<*min_ptr)  //this will  put min value in min_ptr

           *min_ptr=x[i];

   }

}

Explanation:

The above function can be called like :

                                    ranges(x,n,&max,&min);  

where x is array and n is number of elements and max and min are address of variables where maximum and minimum values to be stored respectively.
