The Purpose Of The Linux Kernel And Its Features

Linux Architecture
There are three main parts to Linux :
❖
Core , which implements the basic functions of the OS (process
management, input-output, memory, etc.)
❖
System libraries that define a standard set of functions for use in
applications (performing such functions does not require a transition
to privileged mode)
❖
System utilities (applications that perform specialized tasks)
The Purpose Of The Linux Kernel And Its
Features
Linux implements a monolithic kernel technology. All kernel data and data
structures are in the same address space. There are several functional
components in the kernel.
❖
Process Scheduler - Responsible for the implementation of
multitasking in the system (interrupt processing, timer operation,
creation and completion of processes, context switching)
❖
Memory Manager - allocates a separate address space for each
process and implements support for virtual memory
❖
Virtual File System - Provides a universal interface for interacting
with various file systems and me/ O devices
❖
Device Drivers - Provide direct access to peripherals. They are
accessed through the virtual file system interface
❖
Network Interface - Provides access to the implementation of
network protocols and network device drivers
❖
Interoperability Subsystem - Offers mechanisms that allow
different processes in the system to communicate with each other
Some of these subsystems are logical components of the system, they are
loaded
into
memory
with
the
core
and
remain
there

permanently. Components of other subsystems (such as device drivers) to
implement profitable so that their code could upload them on demand. To
accomplish this, Linux supports the concept of kernel modules.
