CS301 Assignment Statement:

Question 1: [Marks 15]

While transmission through network, it is always important to keep data transmission rate high so data over the network can be increased using two ways; either increases the bandwidth of communication channel or decrease the size of data (compression) to increase the bandwidth utilization.

Lossless data compression algorithms are important in network and Huffman encoding scheme can be used for lossless data compression. Suppose the following string is being transmitted over the network:

“Data Compression in data structure”

We cannot increase the bandwidth of communication channel. Instead we have to compress the given string. Use Huffman encoding scheme to encode the given string.

To encode the string:

Build a table containing the following information about the string.

Build Huffman encoding tree. The tree will be built with the help of characters and their respective frequencies which you will find in step 1.

Calculate how much bits are consumed by original and compressed string. What percentage of bits is saved by Huffman encoding scheme?

Mention step by step construction of Huffman Encoding tree from the above table.
