Im only in 4th sorry i dont think i can help
Explanation:
A.)
we have two machines M1 and M2
cpi stands for clocks per instruction.
to get cpi for machine 1:
= we multiply frequencies with their corresponding M1 cycles and add everything up
50/100 x 1 = 0.5
20/100 x 2 = 0.4
30/100 x 3 = 0.9
CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8
We find CPI for machine 2
we use the same formula we used for 1 above
50/100 x 2 = 1
20/100 x 3 = 0.6
30/100 x 4 = 1.2
CPI for m2 = 1 + 0.6 + 1.2 = 2.8
B.)
CPU execution time for m1 and m2
this is calculated by using the formula;
I * CPI/clock cycle time
execution time for A:
= I * 1.8/60X10⁶
= I x 30 nsec
execution time b:
I x 2.8/80x10⁶
= I x 35 nsec
There are six basic functions of IT.
1. Capture: Compiling detailed records of activities.
2. Processing: Converting, analyzing, computing and synthesizing all forms of data and information.
3. Generation: Organizing information into a useful form.
4. Storage: Retaining information for further use.
5. Retrieval: Locating and copying stored data or information for further processing or for transmission to another user.
6. Transmission: Distributing information over a communication network.
