This document outlines 3 homework questions: 1. Create a letter frequency table from sample texts by counting the frequency of each letter and comparing to known language tables. 2. Take the letter frequency table from question 1 and compute the entropy of each text sample. Also compute the entropy of compressed versions of the texts. 3. Write a literature review on error detection and correction algorithms used in each layer of the TCP/IP network stack.

1. Hello, i have a homework. Can you help? 1 Create letter frequency table - Write a program that
creates letter frequency table. - Choose an alphabet and a sample text. - Example: Start with a
sample "lorem ipsum" text (https://www.lipsum.com/) with English alphabet. - Manipulate text
to contain only small letters: Convert capital letters to small ones and ignore all other characters.
- The program should take the text as input and return a table that contains the frequencies of
each letter defined in your chosen alphabet. - Choose a long English text (could be a book
chapter, news page, etc.). - Choose a long Turkish text (optional, for Turkish students only). -
Compare your results with well known language frequency tables (e.g. https://www3.nd.edu/
busiforc/handouts/cryptography/letterfrequencies.html). - Try with different length of texts and
observe results. 2 Compute the entropy - Use the program you have developed in first question. -
Write a program that takes the output of the first question (the frequency table of letters) as input
and return the entropy value. - Compute entropy of each text sample you've used in the first
question. - Compress each text and compute entropy of the compressed data (Be careful with the
alphabet). Compare results with previous computations. (You are free to use any compression
algorithm.) 3 TCP/IP Stack Error Detection/Correction Write a literature review about the
algorithms and methods used for the error detection and/or correction in the TCP/IP Stack.
Address solutions in each layer.
