  1. Program that translates symoblic instructions to binary instructions?
    assembler
  2. high-level language for business data processing?
    cobol
  3. binary language that the processor can understand?
    machine language
  4. commands that the processor understands
    instructions
  5. high-level language for scientific computation
    fortran
  6. symbolic representation of machine instructions
    assembly language
  7. 240 (1012) and 250 (1015) bytes?
    Terrabyte, petabyte
  8. special language used to describe hardware components
    VHDL
  9. bit size of 1 byte?
    8 bits
  10. define cost effectiveness
    = cost / performance
  11. define performance
    = 1 / execution time
  12. power equation
    P = c v² F
  13. Parallel Speedup / Efficiency
    • Speedup = T1/Tp
    • Efficiency = T1/PTp
  14. Amdahls Law
    • Tserial+Tparallel/P<=Tp
    • Tnew = Tparallelizable/100+Tsequential
  15. Average Memory Access Time
    = Time for a hit + Miss rate * Miss penalty
  16. Gustafson Barsis Law
    sppedup should be measured by scaling the problem to the number of processors not by fixing the problem size
