Answer:
The image of truth table is attached.
Explanation:
In the truth table there is a separate table for the expression (A+B).C and for the expression (A.C)+(B.C) you can see in the truth table that the columns of (A+B).C is having same values as the (A.C)+(B.C).Hence we can conclude that (A+B).C is equal to (A.C)+(B.C).
Answer:
Explanation:
The following piece of code is written in Java. It creates the method as requested that takes in two generic objects and compares them using the .equals() built in Java method. This method will return True if the objects are identical or False if they are not. A test case is used in the code and the output can be seen in the attached image below.
public static <T> boolean comparePerez(T a, T b) {
return a.equals(b);
}
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.
