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. 17
5 10440abcD+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 bc
6 10158In 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] none
1 6947Virtual memory size depends on [a] address lines [b] data bus [c] disc space [d] a & c [e] none
3 12134If 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 7500:2500
