2) A word in memory is 32 bits.(True/false)

3) (M/C) The common type of RAM that is synchronized to read twice per external clock cycle is

               a.   FPM DRAM     b. SDRAM  c. DDR SDRAM   d. RDRAM

4)  (M/C) Given the following addresses(in hex), which address would be aligned for a 32-bit value?

a. 12345676       b.  ABCD755A          c.   38B0F050       d.  AABB3455

5) (M/C) In most two-address or three-address machines the first address is the _________.

a. destination       b.  register     c.   source      d. any of the above

3) c. DDR SDRAM

4) c. 38B0F050

   Explanation: Decimal conversion of 38B0F050 is 951119952 and 951119952 is divisible by 32. so 38B0F050 address would be aligned for a 32-bit value
