Assume a two-level inclusive cache hierarchy, L1 and L2, where L2 is the larger of the two. Consider the following statements. S1: Read misses in a write through L1 cache do not result in writebacks of dirty lines to the L2. S2: Write allocate policy must be used in conjunction with write through caches and no-write allocate policy is used with writeback caches. Which of the following statements is correct? 
Consider a fully-associative data cache with 32 blocks of 64 bytes each. The cache uses LRU (Least Recently Used) replacement. Consider the following C code to sum together all of the elements of a 64 by 64 two-dimensional array of 64-bit double-precision floating point numbers. double sum (double A [64] [64] ) { int i, j ; double sum = 0 ; for (i = 0 ; i < 64; i++) for (j = 0; j < 64; j++) sum += A [i] [j] ; return sum ; } Assume all blocks in the cache are initially invalid. How many cache misses will result from the code?
Consider the following partial Schedule S involving two transactions T1 and T2. Only the read and the write operations have been shown. The read operation on data item P is denoted by read(P) and the write operation on data item P is denoted by write(P) Time Instance Transaction-id T1 T2 1 read(A)   2 write(A)   3   read(C) 4   write(C) 5   read(B) 6   write(B) 7   read(A) 8   Commit 9 read(B)     Schedule S   Suppose that the transaction T1 fails immediately after time instance 9. Which one of the following statements is correct?
Assume a memory access to main memory on a cache "miss" takes 30 ns and a memory access to the cache (on a cache "hit") takes 3 ns. If 80% of the processor's memory requests results in a cache "hit", what is the average memory access time?
What will happen when the data of the jQuery.cache is read from an element? b) Data is read from jQuery.cache c) Unique number is retrieved as elem & Data is read from jQuery.cache d) Data is cleared from jQuery.cache
Consider a computer with 8 Mbytes of main memory and a 128K cache. The cache block size is 4 K. It uses a direct mapping scheme for cache management. How many different main memory blocks can map onto a given physical cache block?

S1: Always remember that regular and frequent practice is essential if you are to learn to write well.
P: Even with the most famous writers, inspiration is rare.
