Welcome, to the realm of Linux! 🤗🌌
🤔 What is Linux?
Linux, at its core, is an open-source operating system that forms the backbone of countless devices worldwide. 🌍 From your trusty smartphones 📱 to supercomputers 🚀, and even the internet itself.
🧐Why Choose Linux?
🎯 Speed and Performance ➡️ Linux is known for its lightning-fast performance and efficient use of resources.💨🚀 Linux allows 👨💼👩💼 multi-user and multi-tasking, with a powerful shell and multiple flavors.
🔒 Top-notch Security:
With Linux, you're in safe hands! Its open-source nature allows a community of passionate developers to constantly enhance security measures, keeping your data secure and your mind at ease. We do not need any anti-virus software.🔐🛡️
🏰 Linux Architecture 🏰
🔧Hardware: The hardware layer of Linux is made up of several peripheral devices such as a CPU, HDD, and RAM.
🌌Kernel: At the heart of Linux lies the mighty Kernel, the foundation that connects hardware and shell (software) like a bridge of knowledge!
🚪Shell: User Interface also known as Terminal; where you write the commands (set of instructions). It can take commands through the user and runs the functions of the kernel.
📜System utility: This layer consists of a set of programs that perform various system-level tasks, such as managing processes, controlling user accounts, and configuring system settings. These utilities are usually command-line programs that are invoked by the user or by other programs.
🖥️Applications: Here users can show their creativity and productivity using a vast array of software applications. From simple text editors and web browsers to sophisticated multimedia tools and development environments.
📜Linux File Hierarchy Structure 🌳
📁 Root Directory (/) - It's the starting point for all paths, the foundation on which the entire file hierarchy is built.
📁 Home Sweet Home: (/home) - This is where users' individual directories reside, offering a safe place for personal files, documents, and configurations. like - /home/username
📁 Command Central: (/bin & /sbin) - Binary executables or Linux programs. These include common Linux commands that are made available for all users in single-user mode. Unlike the /bin directory, the /sbin directory contains binary executables and command line tools that are preserved for the root user.
📁 System Secrets: (/etc) - Contains host-specific system-wide configuration files. It stores configuration files required by all programs as well as startup and shutdown shell scripts.
📁 Gateway to the Web: (/var) - Gateway to the dynamic world of Linux. It stores variable data, including log files, databases, temporary files, and more.
📁 Devices at Your Command: (/dev) - From hard drives to printers, each device is represented as a file in /dev, allowing users to interact with them through the Linux file system. It's the gateway to hardware communication.
📁Temporary files Store: (/tmp) - These are temporary files created by the system and users. Files in this directory are usually a few kilobytes in size and are, in most cases, deleted when a system is rebooted.
📁 Program Paradise: (/usr) - Vast collection of user-friendly programs, libraries, and documentation.
