Bits and Bytes

  1. Sep 8, 2004 #1
    Hello everyone

    I am enrolled in a AP Computer Science course. Currently we are learning about bits and bytes. Could someone please explain the concept of bits and bytes. For example, here are some questions that I have tried doing:

    1. 16-bit binary numbers can be used to represent all non-negative integers from 0 to 2^16 - . I know that is is true, but why?

    2. Design a method for representing the state of a tic-tac-toe board in computer memory. Can you fit your representation in three bytes?


    I know that a tic-tav-toe board has 9 squares. However I become stuck after this.


    Any help would greatly be appreciated.

    Thanks

    It's also true that 16-digit decimal numbers can be used to represent all integers in the range [0, 10^16). Can you explain why?


    Have you tried anything at all?

    16 bits
    2^0
    2^1
    2^2
    2^3
    2^4
    2^5
    2^6
    2^7
    2^8
    2^9
    2^10
    2^11
    2^12
    2^13
    2^14
    2^15
    2^16

    think about this
    this should give you the answer to number one
