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.
Answer:
- <u>1,000W</u> (rounded to one significant figure)
Explanation:
I will answer in English.
The question is:
- <em>What is the power of a filament lamp that connects to the 220 V network, knowing that it has a resistance of 50 ohms?</em>
<em />
<h2>Solution</h2>
<em />
<em>Power</em>, <em>voltage</em>, <em>resistance</em>, and current, are related by either of the following equations:
Where:
- R is resistance in ohms (Ω)
- V is voltage in volts (V), and
- I is current in amperes (A)
Since you know the voltage (<em>220V</em>) and the resistance (<em>50Ω</em>), you can use the last equation:
Since the magnitude 50Ω has one significant figure, your answer should be rounded to one significant figure. That is <u>1,000W.</u>
