1. The number of bit in the "standard" byte found in all modern computers is

   a. 1                                 b. 8

   c. 16                                d. 32


2. The number of different values that can be represented using a 4
   bit code is:

   a. 4                                 b. 16

   c. 8                                 d. 256


3. Convert the binary number 11011 to decimal










4. Convert the decimal number 57 to binary
















5. A signed 8 bit integer can take on values -128, -127, ... -1, 0, 1, .. 127
   If we attempt to add the values 100 + 60 as 8 bit signed integers:

   a. the correct answer will be        b. the program will halt and
      computed                             ask you if you want to send
                                           an error message to Microsoft.
   c. an incorrect answer will be
      computed and your program will
      continue execution.
