Which one you will use to implement critical section?1307
RAM chips arranged in 4X6 array and of 8kX4bit capacity each. How many address lines reqd. to access each byte a. 12 b. 16 c.15 d. 175 8560
abcD+abcd+aBCd+aBCD then the simplified function is ( Capital letters are copliments of corresponding letters A=compliment of a) [a] a [b] ab [c] abc [d] a(bc)* [e] mone (bc)*=compliment of bc6 7981
A 12 address lines maps to the memory of [a] 1k bytes [b] 0.5k bytes [c] 2k bytes [d] none10 19507
In a compiler there is 36 bit for a word and to store a character 8bits are needed. IN this to store a character two words are appended .Then for storing a K characters string, How many words are needed. [a] 2k/9 [b] (2k+8)/9 [c] (k+8)/9 [d] 2*(k+8)/9 [e] none1 5845
Virtual memory size depends on [a] address lines [b] data bus [c] disc space [d] a & c [e] none3 10682
If A>B then F=F(G); else B>C then F=G(G); in this , for 75% times A>B and 25% times B>C then,is 10000 instructions are there ,then the ratio of F to G [a] 7500:2500 [b] 7500:625 [c] 7500:625 if a=b=c else 7500:25002 5676
