ASCII & ANSI
Binary Codes




In the Old American West of the 1850's, Sam Morse's telegraph code replaced the Pony Express. The Morse code is a binary code of long and short signals whose various patterns and combinations represent letters and digits. For example, the familiar S.O.S. distress call in Morse code is ... --- ... With the merger of the telegraph and typewriter, a binary code, similar to that of the LooLooLos, gradually replaced the Morse code. In this new code, a unique binary number represents each keyboard character. This newer code came to be called the ASCII code, an acronym for American Standard Code of Information Interchange. Today all computer networks, including the World Wide Web, use ASCII as their standard. An S.O.S. signal in ASCII looks like this: 1010011   1001111   1010011. ASCII was later expanded to include international characters such as . These extra characters are called ANSI (American National Standards Institute) characters in America, and ISO (International Standards Organization) characters in other parts of the world. An S.O.S. signal in ANSI looks like this: 01010011   01001111   01010011. Notice that each character is represented by 8 digits, rather than by 7 as in ASCII. An S.O.S. signal in hexadecimal looks like this: 53   4F   53, and in decimal like this: 83   79   83.

The table below lists the ASCII and ANSI codes with both their Decimal and Hexadecimal equivalent. The Decimal code is to the left of the character, the Hexadecimal, to the right. The first 32 codes, sometimes called the Control Codes, are those used by printers, modems, and cell phones to make connections to computers. Software programs may define each control character differently, but here are some of the standard definitions:
    Example Control Characters
  •  7 = 07 = CTRL+G = BEL = bell sound (Ding!)
  •  8 = 08 = CTRL+H = BS  = back space
  •  9 = 09 = CTRL+I = TAB = tab key
  • 10 = 0A = CTRL+J = LF  = line feed (next line)
  • 11 = 0B = CTRL+K = VT  = tab down
  • 12 = 0C = CTRL+L = FF  = form feed (new sheet)
  • 13 = 0D = CTRL+M = CR  = carriage return (enter key)
  • 27 = 1B = CTRL+[ = ESC = escape key

ASSIGNMENT

Exercise 1: Use the applet at the top of the page to convert keyboard characters into both their Hexadecimal and Decimal equivalents. Enter the title of your favorite movie over the last year into the Original Text Message box. Press the [ENTER] key. You will see the Hexadecimal and Decimal equivalents of your text. Hilite the Hexadecimal code by dragging your mouse across each character. Copy this code with CTRL+C or Edit/Copy. Also code the name of your favorite actor or actress. On the ASCII wiki page, create a comment, and paste only the Hexadecimal code for your movie and actor. If someone has already chosen your movie and actor, pick another. Earn 3 points.

Exercise 2: Choose one of your fellow student's encoded movie and actor. Decode the movie and actor using the ASCII table. Post your decoded message in a comment. Tell us whose movie and actor you are decoding. If someone has already decoded your choice, pick another. Earn 4 more points.

If you don't get out much, choose your favorite TV show and TV personality. Encode and post them. If you don't like movies and TV, encode and post your favorite song and performer. If you are too good for electronic media, encode and post your last favorite book and author. If you do not imbibe in any cultural offerings whatsoever, why are you in college?
