INDIA RILEY NT1430 LINUX DEC 9 2014 Nt1430 Linux Networking (Unit 1 Linux Server Installation and Configuration) 1. What are multiuser systems and why are they successful? Multiuser operating systems allow the multiple users to access the resources of single systems at a time or at different time. It allows many users to take advantage of the computer’s resources simultaneously. Some permit 100’s to 1000 users to take advantage of the computer’s resources simultaneously. They are successful because

well as workstations‚ it is necessary to consider whether a Linux Based system is appropriate for our organizational needs at this point. Introduction The purpose of this paper is to investigate the pros and cons of using Linux in both a server and workstation environment. During this investigation several Linux distributions will be scrutinized. This examination will disclose what is really necessary to convert to a true Linux environment and will also verify the feasibility of such action

This security measures aide in the subversion of theft and malicious activity. We will discuss these items in depth to address who created them and for what reason. Along with how these technologies changed the operating system to enforce security

In Linux‚ the flow of control during a boot is from BIOS‚ to boot loader‚ to kernel. The kernel then starts the scheduler (to allow multi-tasking) and runs the first userland (i.e. outside kernel space) program Init (which is mostly responsible to run startup scripts for each runlevel)‚ at which point the kernel goes idle unless called externally. init (short for initialization) is a program for Unix-based computer operating systems that spawns all other processes. It runs as a daemon and typically

Linux - The shell ------------------------------------------------- Introduction to the shell The command interpreter is the interface between the user and the operating system‚ hence the name "shell". The shell therefore acts as an intermediary between the operating system and the user thanks to command lines that are entered by the latter. Its role consists in reading the command line‚ interpreting its meaning‚ carry out the command‚ and then return the result via the outputs. The shell

was the default file system for Linux until EXT3 came along. EXT2 still is a favored file system for Flash and USB drives due the lack of journaling. Journaling requires more writes to the storage unit and can be slow on these external devices. The Flash and USB drives have a limited number of write cycles. The Filesystem Hierarchy Standard (FHS) is a reference describing the conventions used for the layout of a UNIX system. It has been made popular by its use in Linux distributions‚ but it is used
