Understanding the root directory

In a typical file system, what is the role of the root directory?

A It only contains system configuration files.

B It stores all user documents only.

C It is a hidden folder that stores temporary files.

D It is the top-level directory that contains all other files and folders.

💡 Hint

Think of the root directory as the main folder from which all others branch out.

The root directory is the starting point of the file system hierarchy. All other files and folders are organized under it, like branches from a tree trunk.

❓ trace

Tracing file path navigation

Given the file path /home/user/documents/report.txt, which folder is the immediate parent of report.txt?

A documents

B user

C home

D /

💡 Hint

Look at the folder just before the file name in the path.

The immediate parent folder is the one directly containing the file. Here, report.txt is inside the documents folder.

❓ identification

Identifying absolute vs relative paths

Which of the following paths is a relative path?

A /etc/hosts

B /home/user/

C documents/report.txt

D /var/log/syslog

💡 Hint

Relative paths do not start with a slash (/).

Absolute paths start from the root directory and begin with '/'. Relative paths are relative to the current directory and do not start with '/'.

❓ Comparison

Comparing file system structures

Which statement correctly compares the file system structure of Windows and Unix-like systems?

A Windows uses drive letters like 'C:\' as roots, Unix uses a single root directory '/'.

B Windows uses a single root directory '/', Unix uses multiple drive letters like 'C:\'.

C Both Windows and Unix use '/' as the root directory.

D Unix uses drive letters like 'C:\', Windows uses a single root directory '/'.

💡 Hint

Think about how Windows identifies drives compared to Unix systems.

Windows organizes drives with letters like 'C:\', 'D:\', each acting as a root. Unix-like systems have a single root directory '/' from which all files and folders branch.

Determining file count in nested directories

Consider this file system structure:

 /
 ├── home/
 │   ├── user/
 │   │   ├── file1.txt
 │   │   └── docs/
 │   │       └── file2.txt
 │   └── guest/
 │       └── file3.txt
 └── var/
     └── log/
         └── syslog

How many files are inside the /home/user directory and all its subdirectories?

A 3

B 2

C 1

D 4

💡 Hint

Count all files directly inside /home/user and inside its folders like docs.

Inside /home/user there is file1.txt and inside docs there is file2.txt. So total files are 2. The /home/guest files are not counted.
