This repository contains the code I wrote as part of the first lab assignment of the Computer Networks Course, Spring 2014, IITM. We are to generate a set of 128 bit string (refer generate.c) which is stored in a file (input.txt). This file is read using apply_crc.c which tries the following for each bit string:

• Generate 1 bit errors on 10 different trials
• Generate consecutive 2 bit errors on 10 different trials
• Generate burst errors of length < 30 on 10 different trials
• Generate odd number of bit flips on 10 different trials

and checks whether the corrupted bit string fails on CRC-check. Refer output.txt for the output of this check.

First run,

./generate <input_file> <no_of_strings >

to generate the bit strings. To check correctness of CRC, run:

./ec <input_file> <output_file>
