Answer each of the following with a True(T) or FALSE(F) (1) SRAM uses flip-flops

Question

Answer each of the following with a True(T) or FALSE(F) (1) SRAM uses flip-flops while DRAM uses capacitors. So the capacity of SRAM is normally larger than that of DRAM with the same cost. (2) If you can find the value x in the cache, you can also find it in the main memory too. (3) In IEEE 754 floating-point binary representation, the negative exponent for a double or single is represented in its 2's complement number format. (4) The information stored in DRAM will be lost without refreshing frequently. (5) In pipelining, three types of are structural hazards, data and loop hazards. (6) Pipelining improves performance by increasing instruction throughput. (7) A cache is a small high speed memory that stores a subset of the information in the RAM. (8) The unit of data transfer between cache and main memory is a word. (9) Virtual memory is a technique of using disk to extend the apparent size of physical memory. (10) Single-cycle and multi-cycle machines differ in CPI but have the same cycle time.
