1. Computer architecture can be defined as a set of rules and methods that describe the functionality, management and implementation of computers. To be precise, it is nothing but rules by which a system performs and operates.

2. Performance A / Performance B
= Execution time B / Execution time B

Thus the performance ratio is 15/10 = 1.5

Performance A / Performance B = 1.5

Therefore A is 1.5 times faster than B

4. Throughput is calculated as requests/unit of time. The time is calculated from the start of the first sample to the end of the last sample. This includes any intervals between samples, as it is supposed to represent the load on the server. The formula is: Throughput = (number of requests) / (total time).

The calculation of response time is: T_response = n/r – T_think = (5000/ 1000) – 3 sec. = 5 – 3 sec. Therefore, the response time is two seconds.

7. Big-endian is an order in which the “big end” (most significant value in the sequence) is stored first, at the lowest storage address. Little-endian is an order in which the “little end” (least significant value in the sequence) is stored first.
