Computing Systems

1. Real Numbers

   • MxBe
     • The e is like a power sign so it is smaller
       • M= is the Mantissa
         • B= the BASE
           • E=the exponent

2. Binary

   • it is 8 bit
     • It only uses 1 and 0
       • The highest number it can make if all 8bits are on is
         • 255

3. ASCII

   • It sands for American Standard Code for Information Interchange
   • It uses 7bits up to 128characters
     • Extend ASCII uses 8 bit to encode up to 256
       • It uses Printable characters (upper,lower case,symbols)
         • Non-printable characters these are known as control charcaters
