with open('celcius.dat', 'r') as fIn, open('fahrenheit.dat', 'w') as fOut:
for line in fIn:
fahrenheit = 9.0 / 5.0 * float(line) + 32
fOut.write("%.1f\n" % fahrenheit)
You can control the number of decimals in the formatting clause in the write statement.
Yes, "technology" doesn't have to be all about computers or cell phones.. Technology is anything that is a new advance in knowledge and books were once a great advance in that field.
Answer:
c. You cannot change the name, return type, or parameters of a method defined by the interface.
Explanation:
When implementing an interface:
- The return type of the implementing method should be same as the one defined in the interface.
- The parameters of the implementing method should be the same as defined in the interface.
- The name of the method should be the same as that defined in the interface.
So among the given options , option c is the most relevant as it captures all the above conditions.
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.
