=========================================== Assignment #05 - viewing a memory dump in hexadecimal =========================================== - Ian! D. Allen - idallen@idallen.ca - www.idallen.com Available online: Tuesday February 8, 2011 Deliverables: In-lab demo to your instructor during Week 5. There is nothing to hand in. 1. Analyze the file text.bin in the Data Files section of the Course Notes. Display the file in hexadecimal and show your instructor which line-end characters are used to end each of the five lines in that text file. Which lines would typically be found in text files on which Operating Systems? You may use the DEBUG hex dump program (in a DOS window) or you can download a free hex editor program (e.g. XVI32 from www.chmaas.handshake.de or "hexedit" from www.physics.ohio-state.edu) and use it to identify the line-end characters. 2. Decode to ASCII the hexadecimal bytes from the 140_attack.txt and 145_textbook_secrets.txt file in the Class Notes area and show your instructor the decoded strings. This lab is an in-lab demo. There is nothing to hand in.
