Doubt on Write through
Consider the following specifications: Hit ratio for read = 0.8, Hit ratio for write = 0.9 Block size =2 words, cache of 10 ns is 10 times faster than main memory On any miss entire block is moved from main memory to cache memory 20% references are for write operations What is avg access time with write through using 1) Write allocate 2) No write allocate

The L2 and L3 cache memories are divided into a blocks of 5 words.
Suppose there is a system which has 3 levels of cache i.e L1, L2 and L3. The access times of L1, L2 and L3 cache memories are 100 ns/word, 150 ns/word, and 250 ns/word respectively. The L2 and L3 cache memories are divided ... are 80% and 90% respectively. What is the average access time? A. 103ns B. 108ns C. 220ns D. 112ns

Consider 2 stations at a distance of 1 km from each other (Aloha)
Consider 2 stations at a distance of 1 km from each other. A station transmits frames of length 100 bits at the rate of 1 Mbps. Velocity of propagation is 2 * 108 m/s. Assume that each station generates frames at an average rate of 10000 frames per second. What is the probability of collision for pure ALOHA and slotted ALOHA ?

Kenneth Rosen Edition 7 Exercise 2.5 Question 40 (Page No. 177)
Show that if $S$ is a set, then there does not exist an onto function $f$ from $S$ to $P(S),$ the power set of $S$. Conclude that $\mid S\mid < \mid P(S)\mid .$ This result is known as Cantor's theorem. [Hint: Suppose such a function ... $s$ can exist for which $f (s) = T.]$

How it works. Please give some example.
Consider the following foo function and identify the return value of foo function. int foo (unsigned int n) { int c, x = 0; while (n! = 0) { if (n & 01) x++; n >>= 1; } return x; } (a) It counts the total number of bits ... counts the number of bits which are zero. (c) It counts the number of occurrences of 01. (d) It returns the same value as n'.
