X11-Xorg Server And X-11 Forwarding

X11 Server and X11 Forwarding part-2

Students will learn what a Linux Display Manager is and its role as the graphical interface that handles the user login screen.  They'll understand how it's responsible for starting the graphical server and launching their chosen desktop environment, and be introduced to popular examples like GDM (for GNOME) and LightDM.

Accessibility Options in Linux

Filesystem Types and Creating Different Filesystems

Students will learn the essential command-line tools for performing filesystem maintenance to keep their Linux systems healthy and running smoothly.  They'll master using df and du to monitor disk space usage, and the powerful find command to locate files for cleanup and management.

Students will learn the fundamental Linux concept of mounting and unmounting filesystems to make storage devices like hard drives and USBs accessible.  They'll master using the mount command to attach a device to a directory in the file tree, the umount command to safely detach it, and will be introduced to the /etc/fstab file for creating permanent mounts.

File System Hierarchy In Linux

All about Files / Folders Ownership and associated Permissions

Students will learn about the special permission bits that provide advanced access control for files and directories in Linux.  They'll discover the purpose of SUID for temporary privilege elevation, SGID for managing group collaboration in shared directories, and the Sticky Bit for protecting files in public folders like /tmp.

SUID, SGID And Sticky Bit Part-2

What are Soft and Hard Links

Finding Files in Linux

Students will learn the essential skill of creating disk partitions and understand the two main partitioning schemes. They'll discover the differences between the traditional MBR (Master Boot Record) and the modern GPT (GUID Partition Table) standards and use a command-line tool like fdisk to create new partitions on a storage device.

Creating Partitions using MBR and GPT part-2

Managing Disk Quotas

Students will learn how to use command-line tools to determine the hardware installed in their Linux system.  They'll then learn how to manage the kernel modules, or drivers, that control this hardware, using commands like lsmod to list currently loaded modules and modprobe to load or unload them as needed.

Boot Sequence / Kernel Parameters / Single User Mode / Proper Shutdown

Students will learn about the evolution of the Linux initialization process, the system responsible for starting all services at boot time.  They'll compare the sequential SysV init, the event-based Upstart, and the modern, parallel systemd which is now the standard for most major distributions, understanding how the boot process has become faster and more efficient over time.
