EVOLUTION OF LINUX OPERATING SYSTEM PPT

„ It has been designed to run efficiently and reliably on common PC hardware, but also runs on a variety of other platforms
„ The core Linux operating system kernel is entirely original, but it can run much existing free UNIX software, resulting in an entire UNIX-compa[r]

This chapter defines system software and discusses two types of system software: operating systems and utility programs. You learn what an operating system is and explore user interfaces, operating systems features, and operating system functions.

It should be noted, however, that a real-time partition al- ways include a few peculiar nonreal-time processes. In fact, the Linux kernel design makes use of some processes, called
kernel threads, which execute only in Kernel Mode and per- form system-related activities. Besid[r]

PAM is based on a shared library that can be used by any system component that needs to authenticate users. Access control under UNIX systems, including Linux, is performed through[r]

This chapter defines system software and discusses two types of system software: operating systems and utility programs. You learn what an operating system is and explore user interfaces, operating systems features, and operating system functions.

The objectives of this chapter are to describe the services an operating system provides to users, processes, and other systems; to discuss the various ways of structuring an operating system, to discuss the various ways of structuring an operating system.
