How can I reduce the white space on the right of the page?

\section{CH sum}
Checksum error detection is a method used to identify errors in transmitted data. The 
process involves dividing the data into equally sized segments and using a 1’s 
complement to calculate the sum of these segments. The calculated sum is then sent along 
with the data to 
the receiver. At the receiver’s end, the same process is repeated and if all zeroes are 
obtained in the sum, it means that the data is correct.

Checksum – Operation at Sender’s Side
Firstly, the data is divided into k segments each of m bits.
On the sender’s end, the segments are added using 1’s complement arithmetic to get the 
sum. The sum is complemented to get the checksum.
The checksum segment is sent along with the data segments.
Checksum – Operation at Receiver’s Side
At the receiver’s end, all received segments are added using 1’s complement arithmetic 
to get the sum. The sum is complemented.
If the result is zero, the received data is accepted; otherwise discarded.
