Answer: c) 2hrs 40 min

Explanation:

Rate of working of Computer X is = 240 files/ (4 × 60min)

= 1 file / min

Rate of working of Computer Y is = 240files/ (8×60min)

= 0.5 file/min

The combined rate for computer X & Y is = 1 + 0.5 = 1.5 file/ mins.

Therefore, time taken to process 240 files is = 240/1.5

= 160mins

= 2hrs 40mins

2- There are many different design parameters that are important to a cache’s overall performance. Below are listed parameters f
katen-ka-za [31]

Answer:

1. 2588672 bits

2. 4308992 bits

3. The larger the data size of the cache, the larger the area of ​​memory you will need to "search" making the access time and performance slower than the a cache with a smaller data size.

Explanation:

1. Number of bits in the first cache

Using the formula: (2^index bits) * (valid bits + tag bits + (data bits * 2^offset bits))

total bits = 2^15 (1+14+(32*2^1)) = 2588672 bits

2. Number of bits in the Cache with 16 word blocks

Using the formula: (2^index bits) * (valid bits + tag bits + (data bits * 2^offset bits))

total bits = 2^13(1 +13+(32*2^4)) = 4308992 bits

3. Caches are used to help achieve good performance with slow main memories. However, due to architectural limitations of cache, larger data size of cache are not as effective than the smaller data size. A larger cache will have a lower miss rate and a higher delay. The larger the data size of the cache, the larger the area of ​​memory you will need to "search" making the access time and performance slower than the a cache with a smaller data size.
