Lab Objective: Objective of this lab is to give some background of Linux and elaborate the procedure of installing Linux.
FACULTY OF TELECOMMUNICATION AND INFORMATION ENGINEERING COMPUTER ENGINEERING DEPARTMENT Operating systems o Each component should perform a single task o Multiple components can be combined and chained together for more complex tasks o An individual component can be substituted for another, without affecting other components
2.5 What is Linux? Linux kernel The Linux kernel is an operating system kernel used by the Linux family of Unix- like systems. It is one of the most prominent examples of free and open source software. o Developed by Linus Torvalds o Strictly speaking, ‘Linux’ is just the kernel Associated utilities o Standard tools found on (nearly) all Linux systems o Many important parts come from the GNU project Free Software Foundation’s project to make a free Unix Some claim the OS as a whole should be ‘GNU/Linux’ Linux distributions o Kernel plus utilities plus other tools, packaged up for end users o Generally with installation program o Distributors include: Red Hat, Debian, SuSE, Mandrake Run diskmgmt.msc command Booting: In computing, booting (also known as booting up) is a process that begins when a user turns on a computer system and prepares the computer to perform its normal operations. On modern computers, this typically involves loading and starting an operating system.
FACULTY OF TELECOMMUNICATION AND INFORMATION ENGINEERING COMPUTER ENGINEERING DEPARTMENT Operating systems The boot sequence is the initial set of operations that the computer performs when power is switched on. A boot loader is a computer program that typically loads the main operating system or runtime environment for the computer after completion of a power- on self-test. 3- Installation Dual Boot Partitions Root boot swap File formats Free some space on your hard disk for installing Linux and delete it. Now when Linux installation will run you will have to select this unpartitioned area for your Linux installation. Perform media check on Linux installation CDs to confirm the integrity of the installing media. There are two modes of installation o Texture Interface for professionals o Graphical User Interface for novice people It is recommended to select the latter option. At the time of partitioning, you will be prompted to select ‘manual partitioning’ or ‘automatic partitioning’. Automatic partitioning is recommended for new users. For running NS-2 or some other development tools later in Linux, it is recommended to install all development packages at the time of installation. Otherwise you can install them later just like ‘add/remove window components’ in windows. Select the ‘Boot from CD option’ and start installation.. To help you during the installation procedure, some tips are normally provided on the left top corner of the screen.
