Answer:
The correct answer is d) All of these are correct.
Explanation:
ETL stands for Extract, Transform and Load. An ETL system extracts data from the sources, enforces data quality and consistency standards, conforms data so that separated and maybe unrelated sources can be used together, and as a final step delivers data in presentation-ready formats so that developers can build applications and end users can take decisions.
Answer:
The typedef struct is as follows:
typedef struct jumper_t {
char name[16];
double tries[N_TRIES];
double best_jump;
double deviation;
} jumper_t;
The declaration of jlist is:
jumper_t jlist[10];
Explanation:
This defines the typedef structure
typedef struct jumper_t {
The following declares the variables as stated in the question
<em> char name[16];
</em>
<em> double tries[N_TRIES];
</em>
<em> double best_jump;
</em>
<em> double deviation;
</em>
}
This ends the typedef definition
jumper_t;
(b) The declaration of array jlist is:
jumper_t jlist[10];
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
Without system software, system can not run on the other hand without application software, system always runs
