6 If a main memory has 2^64words,and the word size is 2 bytes, then how
many wires are needed in the date bus?
(A) 16 (B) 32 (C) 64 (D) 128
我是這樣算 2^64 X 2 X 2^3 = 2^68
所以需要68條線 可是沒這個答案
7 the logical deductive-reasoning principle, called resolution says that
if p q and r are statement, then statements (p and q) and (p or ~q)
collective imply
(A) p (B) p or r (C) p or q or r (D) none of the above
這題一點頭緒都沒有 也不知道是可以查那個科目
