Overview to SSH

  SSH, or Secure Shell, is a network protocol that allows you to securely access a remote computer over an unsecured network. It is often used by system administrators to manage servers, but it can also be used by anyone who needs to access a remote computer in a secure way. SSH works by encrypting all data that is sent between the client and the server. This means that even if someone is able to intercept the data, they will not be able to read it. SSH also provides authentication, so that only authorized users can access the remote computer. There are many different ways to use SSH. Here are a few common uses: To access a remote server and manage it. This is the most common use of SSH. System administrators use SSH to install software, configure settings, and troubleshoot problems on remote servers. To transfer files between computers. SSH can be used to securely transfer files between two computers, even if they are on different networks. To connect to a remote database. SSH can...

File System Hierarchy and Permissions - Linux

  File System Hierarchy: The Unix-like file system hierarchy is a structured organization of directories and files. It starts from the root directory ("/") and branches out into various subdirectories. Here are some of the most important directories and their purposes: / (Root Directory): The top-level directory in the file system hierarchy. Everything on the system is under this directory. /bin (Binary): Contains essential system binaries (executable files) required for system booting and repair. /boot: Contains boot-related files, including the kernel and bootloader configuration. /dev (Devices): Contains device files representing hardware devices, such as hard drives, keyboards, and serial ports. /etc (Etcetera): Houses system-wide configuration files and scripts. /home: User home directories are stored here. Each user has their own subdirectory here. /lib (Library): Contains shared libraries needed by system programs and applications. /mnt (Mount): Used for tempor...

What is kernal and its types and uses?

A kernel is the central component of an operating system that manages all the resources and communicates with both software applications and hardware devices on a computer. In simple terms, it acts as an intermediary between the user’s requests and the computer's hardware. A kernel provides a variety of services to other parts of the operating system and to applications, including memory and process management, interrupt handling, and system calls. It also acts as a bridge between the hardware and software components, translating requests from the software into actions performed by the hardware.  There are different types of kernels, including monolithic kernels, microkernels, and hybrid kernels.  Monolithic kernels are designed to be large and comprehensive, providing all the basic system functions in a single, unified binary file.  Microkernels, on the other hand, are designed to be small and modular, with each component of the system being implemented as a separate pr...

How Linux Works?

  Linux is a free and open-source operating system that is based on the Unix operating system. It is composed of the Linux kernel, which is the core of the operating system, and a set of user-space programs and libraries that provide common services and interfaces. The Linux kernel is responsible for managing system resources, such as memory and CPU time, and providing services to user-space programs through system calls. It also includes device drivers that allow it to interact with hardware devices, such as storage devices and network interfaces. User-space programs and libraries provide a wide range of functionality, including system utilities, such as the command-line shell and text editors, as well as graphical user interfaces, web browsers, and programming languages. These programs and libraries are typically written in C and C++ and are executed by the kernel through system calls. Linux also supports a wide range of file systems, including ext4, XFS, and NTFS, as well as net...
