    • A*BCD*+
    • AB*CD+* (
    • A*B*CD+
  2. 2. SIMD represents an organization that ______________
    • refers to a computer system capable of processing several programs at the same time.
    • represents organization of single computer containing a control unit, processor unit and a memory unit.
    • includes many processing units under the supervision of a common control unit
    • none of the above.
  3. 3. Floating point representation is used to store
    • Boolean values
    • whole numbers

    • integers
  4. 4. Assembly language
    • uses alphabetic codes in place of binary numbers used in machine language
    • is the easiest language to write programs
    • need not be translated into machine language

    • Register
    • Encoder
    • Decoder
    • Flip Flop
