Linux Architecture

Linux Architecture:




What Is Kernel & Shell:

• Kernel - Kernel is main part of an O.S., Kernel is used to interact with hardware, manage I/O devices, manage resources like cpu, ram, hdd, etc,. & used to manage Processes.
• Shell - Shell is a text based program. Users can only interact with shell, then shell interacts with kernel & finally kernel can interact with hardware.

Linux Kernels:

• Linux Kernel is monolithic.
• Traditional Unix kernels are compiled & linked statistically.
• Kernel threading.
• Multilevel application support.
• Linux is a non-pre emptive kernel.
• Multiprocessor support.
