Answer:
Option d) B is 1.33 times faster than A
Given:
Clock time,
No. of cycles per instructions,
Solution:
Let I be the no. of instructions for the program.
CPU clock cycle, = 2.0 I
CPU clock cycle, = 1.0 I
Now,
CPU time for each can be calculated as:
CPU time, T =
Thus B is faster than A
Now,
Performance of B is 1.33 times that of A
Answer:
The space available will vary between 800 GB (100%) and 400 GB (50%) of the total disks, depending on the RAID level.
The OS will handle the RAID as a single disk.
Explanation:
Each RAID level implements parity and redundancy in a different way, so the amount of disks used for this extra information will reduce the space available for actual storage.
Usual RAID levels are:
<u>RAID 0:</u> does not implement any redundancy or parity, so you will have available 100% of the total storage: 8 x 100 GB = 800 GB
<u>RAID 1:</u> Duplicates all the information in one disk to a second disk. Space is reduced in half: 400 GB
<u>RAID 5:</u> Uses the equivalent of 1 disk of parity data distributed evenly on each disk, meaning the space available is of the total disks:
of 800 GB = 700 GB
Writting and reading the information on a RAID storage is handled by a raid controller, either implemented in hardware or software. The OS will "see" a single disk and will read or write information as usual.
