What is Linux
Linux is the sort of operating system using Linux kernel or Linux kernel itself
-
The name of Linux comes from the Linus’ *nix, it means unix of linus
*nix means about Unix, thus it shows that Linux is Unix derived operating system -
Linux is the open source operating system, and many developer uses Linux based customized OS
-
Linux are used on Cloud computing, Embedded system, Research areas
Why We have to study Linux
Studying about Linux is highly difficult work, but it is worthy
-
Deep Understanding Operating System
-
High flexibility and customizability
-
Hardware portability and dependency
-
There are many Linux-based environments.
Concept of kernel and Shell
Kernel is OS itself, and Shell is the function that uses OS easily
-
Kernel gives interface between hardware and application program
and handle the computer resource -
Shell covers kernel, it gets the user input and process output with system
-
Shell connects between User and Linux
Concept of kernel and Shell
