What does the 'ifconfig' command provide details about?

• A. Network interfaces
• B. Disk partitions
• C. User accounts
• D. File permissions

Answer: (A)

The 'ifconfig' command is primarily used in Unix-like operating systems to configure, manage, and query network interface parameters. When executed, it displays information related to network interfaces, such as their IP addresses, netmasks, broadcast addresses, and interface statistics like data transmission rates and error counts. This command is crucial for network configuration and troubleshooting, allowing users to assess the status and configuration of their network interfaces effectively. Understanding network interfaces is essential for managing connections to networks, identifying issues, and configuring systems for optimal network performance.

The other options pertain to different system areas: disk partitions are managed using commands like 'fdisk' or 'lsblk', user accounts are handled through commands like 'useradd' or 'passwd', and file permissions are modified with commands such as 'chmod'. Hence, 'ifconfig' specifically relates to network interfaces, making it the correct answer.
