How is the connection and display of file systems in Linux operating system carried out?

In Linux, the connection and display of file systems are performed using the mounting mechanism (mount). It is a process where a file system on a device (like a hard drive, USB flash drive, or network resource) is attached to a specific point in the directory hierarchy.

Main points:

• Mount point: a directory in the existing file system where the new file system will be attached.
• The mount command is used to connect the file system:

mount /dev/sdb1 /mnt/usb

• After mounting, the contents of /dev/sdb1 will be accessible in /mnt/usb.
• Information about mounted file systems is stored in /etc/mtab or /proc/mounts.
• To automatically mount at system startup, use /etc/fstab.

Thus, Linux provides a unified directory tree into which various devices and network resources can be connected, providing transparent access to them.
