ASCII Graded LAB

Part I

• Each student will choose the word that consists of 3-4 characters.
• Each student will encode the word using ASCII code and binary number system as follows:
  • First, each letter will be encoded using ASCII code that corresponds to the letter. ASCII table will be used to find the ASCII code for each letter.
  • Second, the ASCII code will be converted to the binary number. Use 8 bits for each letter even if there are leading zeros.
  • Third, after all letters in the word are encoded, you will write the binary code that corresponds to the original word by replacing each letter with the binary code that was found and send encoded message to student that next to you on the right (Rachel to Veronica, Veronica to Zack, Zack to Matthew, Matthew to Erica, Erica to Nicole, Nicole to Joe and Joe to Rachel)
• Here is the simple example for the word IF
  • Letter I has ASCII code 73 and letter F has ASCII code 70
  • The binary code (the binary number) that corresponds to 73 is 01001001 (use 8 bits even if the first bit is 0) and the binary code that corresponds to 70 is 01000110.
  • The binary code for word IF is: 01001001 01000110

  Part II

  In this part each student will decode the message and recover original word

  Submission

  • For encoding: write all calculations on the paper with your name. DON'T WRITE your original word on that paper! The original word that each student encoded will be sent by e-mail to ykortsarts@mail.widener.edu
  • For decoding: add your name to the paper you received from your friend. Write all calculations for decoding including the recovered word and submit your paper.
