What Is Linux? From Kernel to IoT, DevOps, & Supercomputers
Linux, a versatile open-source operating system developed by Linus Torvalds, features a kernel that manages hardware interactions, surrounded by system libraries and utilities, with user space providing interfaces for applications, and is distributed in various "distros" for diverse computing platforms.
MAIN POINTS FROM TRANSCRIPT
- Linux is an open-source OS running on PCs, smartphones, servers, and mainframes.
- The Linux kernel manages hardware interactions, memory, and processor scheduling.
- System libraries and utilities provide foundational functions for applications.
- User space includes the command line, desktop environments, and application interfaces.
TAKEAWAYS
- Linux administrators simplify terminology, using terms like "distros" and "repos."
- Linux's kernel allows applications to operate without knowing hardware details.
- The system libraries prevent applications from needing to reinvent basic functions.
- Linux distributions integrate the kernel with libraries and utilities for installation.
