ating systems written in C, a high-level programming language, and its natural portability and low price made it a popular choice among universities. Initially, two main dialects of Unix existed: one produced by AT&T known as System V, and one developed at UC Berkeley and known as BSD. In recent years, many other dialects have been created, including the highly popular Linux operating system and the new Mac OS X (a derivative of BSD).

Linux is a modem, free operating system based on UNIX standards. First developed as a small but self-contained kernel in 1991 by Linus Torvalds, with the major design goal of UNIX compatibility. Its history has been one of collaboration by many users from all around the world, corresponding almost exclusively over the Internet.

This chapter to explore the history of the UNIX operating system from which Linux is derived and the principles upon which Linux’s design is based, to examine the Linux process model and illustrate how Linux schedules processes and provides interprocess communication, to look at memory management in Linux, to explore how Linux implements file systems and manages I/O devices.
In this chapter, we introduce many concepts associated with multithreaded computer systems, including a discussion of the APIs for the Pthreads, Windows, and Java thread libraries. We look at a number of issues related to multithreaded programming and its effect on the design of operating systems. Finally, we explore how the Windows and Linux operating systems support threads at the kernel level.
Linux is a Unix-like computer operating system assembled under the model of free and open source software development and distribution.Linux was originally developed as a free operating system for Intel x86-based personal computers. It has since been ported to more computer hardware platforms than any other operating system. Most Linux distributions support dozens of programming languages.
Welcome to the fascinating world of open source software that is Linux.
In this book, I introduce you to the wonders of the Linux operating
system, originally created as a labor of love by Linus Torvalds in the early
1990s. My goal is to initiate you into the rapidly growing ranks of Linux users
and enthusiasts busily rewriting the rules for the operating system marketplace.
If you’ve contemplated switching to Linux but find the prospect too forbidding,
you can relax. If you can boil water or set your alarm clock, you, too, can
become a Linux user. (No kidding!)...
This HOWTO is dedicated to all the (soon to be former?) DOS and Windows users who have decided to
switch to Linux, the free UNIX clone. The purpose of this document is to help the reader translate his or her
knowledge of DOS and Windows into the Linux environment, as well as providing hints on exchanging files
and resources between the two OSes
The Developer’s Guide describes intermediate and advanced development topics, such
as building database applications, writing custom components, and creating Internet
Web server applications using Kylix, Delphi for the Linux operating system. The
Developer’s Guide assumes you are familiar with using Linux and understand
fundamental programming techniques. For an introduction to Kylix programming
and the integrated development environment (IDE), see the online Help and the
Quick Start manual.
Linux is the name of a computer operating system and also the name of the operating system kernel. It is probably the most famous example of free software and open source development.
The first Linux version written by Linus Torvalds in 1991, when he was a student at the University of Helsinki in Finland. He worked with enthusiasm for 3 consecutive years and released Linux version 1.0 in 1994. Key component was developed and launched on the market under the GNU General Public License. So that anyone can download and view the source code of Linux...
This book was written for anyone using Linux, from new users to experts who want to explore this wonderful
operating system. The tips and tricks in this book were discovered by myself over years of experience using
Linux, and learning about it. Some are very basic tips to make your computing life easier, others are
advanced tricks that can save you days of work.
A Linux smart home is about controlling and monitoring devices and information around your home using a standard personal computer, Linux, and its vast array of open source tools. You don’t have to be a master programmer to create one. If you like to tinker with Linux, Linux Smart Homes For Dummies will guide you through cool home automation projects that are as much fun to work on as they are to use.
