ITPEC IP October 2023 Question 18
In the description below concerning a file system, which of the following is an appropriate combination of terms to be inserted into blanks A through C?
When files and directories on a PC are managed hierarchically, the directory at the highest level is called the A directory, and the directory that a user is now manipulating is called the B directory. A notation that uses the B directory as its starting point and shows the location of a file or a directory is called a(n) C path.
Explanation
A: root, B: current, C: relative — the top of the tree is the root directory; the one being worked in is the current directory.
- •A: the directory at the highest level of the hierarchy, from which every other directory branches, is the root directory
- •B: the directory the user is working in now is the current (working) directory
- •C: a path written starting from the current directory, such as
../data/a., is a relative path; a path written from the root, such astxt /home/data/a., is an absolute pathtxt
Answer (d)
Why not others:
- •(a) — swaps root and current, and a path from the current directory is not absolute
- •(b) — swaps root and current; C is right
- •(c) — A and B are right, but an absolute path starts from the root, not the current directory
Key rule: An absolute path starts at the root and points to the same file wherever you are; a relative path starts at the current directory and changes meaning when you move.
