CSCI-903 Assignment 6

• There will be an unannounced quiz on Teagueduino inputs and outputs.
• Write out answers to the following questions, using class notes and/or the Internet to look up the answers you don’t know.
  1. Write a list of all the combinations of 4 bits in numerical order (0000 through 1111), along with their corresponding decimal and hexadecimal values. The following table shows the list with the first two and last two rows filled in for you:

     Binary	Decimal	Hexadecimal
     0000	0	0
     0001	1	1
     1110	14	E
     1111	15	F

  2. What does ASCII stand for?
  3. How many bits are used for each ASCII code point?
  4. How many ASCII code points are there?
  5. What are the ASCII codes for the characters '3', 'C', 'S', 'c', and 's'? Answer in both binary and hexadecimal.
  6. How many bits are used for each ISO-Latin-1 code point?
  7. How many ISO-Latin-1 code points are there?
  8. What are the ISO-Latin-1 codes for the characters 'Ã', 'Ó', 'ã', and 'ó'? Answer in both binary and hexadecimal. (The A’s have tildes over them; the O’s have accents acute over them.)
  9. What is the relationship between ISO-Latin-1 and ISO-8859-1?
  10. How are the binary code points for ASCII and ISO-Latin-1 related to each other?
  11. How are the binary code points for ASCII, ISO-Latin-1, and Unicode related to each other?
  12. Define the terms, font, glyph, and character. Relate the three terms to one another.

Your first Teagueduino assignment will be to code your Teagueduino so that the 5 output LEDs count in binary, one step each time you press and release a button connected to input 1.
