Answer:
Name of Operating System: Ubuntu
Five legal file names:
inventory.txt
total.txt
NIKKAH.txt
Defaulter.txt
studenT.txt
Five illegal file names:
wel/come.txt
..
MY>note.txt
.
my<work.yxt
Explanation:
To fix the illegal name:
1. Remove the special character, so it becomes welcome.txt
2. Remove the double dot and rename using text characters
3. Remove the special character, so it becomes MYnote.txt
4. A file cannot be named using dot. So we rename to a textual name
5. Remove the special character, so it becomes mywork.txt
Some additional rule for naming of files legally in Unix is that, you cannot use a reserved word to name your file. Starting a file name with number is allowed. Starting a file name with dot make the file to be hidden.
Answer: d. incremental backup
Explanation:
In incremental backup it copies only the files that have changed since the last full backup. It does not backup all the files just like the full backup. it however backup those copies into the system which has changed since the last backup.

Increment backup also use less disk space.
Cloud backup uses most increment backup for its application.

Option 4: Text => A text is nothing but words written together to convey a meaning. Though we feel like it suits the question, since the question speaks about the place, then it must definitely be fact and not just text.

A partial dependency exists.
We have two types of dependency. The partial dependency and the transitive dependency.
The answer here is partial dependency. It occurs when the attribute only depends on some parts of the element. In such attribute, the primary key is the determinant.
It can be shown as;
XY→WZ , X→W and XY is the primary key or the only candidate key
