Module 2: Using a Computer and Managing Files using Ubuntu and the Gnome Desktop Section 1: Computer Environment _________________________________ 2.1 Using a Computer and Managing Files: Computer Environment _____________________________________________________________________________ 2.1.1 First Steps with the Computer 2.1.1.1 Start the computer. • Press the On/Off switch on front of the computer. This will initiate the boot process. During this process the start-up routine that is stored in the ROM of the computer will take control of the computer. One of the things this routine does is to read certain areas of the hard drive to search for the operating system. The start-up routine will then load the operating system into the RAM of the computer and pass over control to it. Depending on how the computer has been configured, one of three things will happen: 1. The operating system will automatically load the GUI (Graphical user interface) and start this for a default user. The system will be available for immediate use. 2. The operating system will automatically load the GUI, but you will be prompted to enter a username and password. These will be given to you by who ever installed the system. 3. Only the text based operating system will load. In this case you will need to logon and then start the GUI. In this case you will see a black screen on which the prompt Logon: appears. Suppose you have been given the username GenUser and password V2wTkN7. Remember that passwords are case sensitive. If you are given a password, you must enter it exactly as given. Logon to the GUI • When the logon window appears, type in your username and password exactly as given. When you type the password, for example V2wTkN7, a series of stars ****** will appear in the password window. This is so that no-one can read your password by looking over your shoulder. • Click the OK button. Unless you have a valid username and password, you will not be able to log on to the system.
