On CentOS or Red Hat LinuxOn which Distros will the prompt for a regular user will likely look like this: [dave@mycomputer ~]$ On CentOS or Red Hat LinuxOn which Distros will the superuser's prompt will look like this: [root@mycomputer ~]# usernameWhat is the name of the user that runs the shell (Shell default Prompt) hostnameWhat is the name of the host on which the shell runs. (Shell default Prompt) current_directoryThe directory that the shell is currently in. A ~ means that the shell is in the current user's home directory. (Shell default Prompt) shell_type$ indicates the shell is run by a regular user.# indicates the shell is run by the superuser root.Command Line Structurecommand [option(s)/parameter(s)...] [argument(s)...] Double quotes Single quotes Escape characters

In Bash, there are three types of quotes:

Double Quotestell the shell to take the text in between the quote marks as regular characters.Single Quotesrevoke any special meaning from each character Escape Characters " \ "We can use BLANK to remove special meanings of characters from Bash.InternalThese commands are part of the shell itself and are not separate programs. There are around 30 such commands. Their main purpose is executing tasks inside the shell ExternalThese commands reside in individual files. These files are usually binary programs or scripts. When a command which is not a shell builtin is run, the shell uses the PATH variable to search for an executable file with same name as the command.In addition to programs which are installed with the distribution's package manager, users can create their own external commands as well.typeThe command BLANK shows what type a specific command is touchCommand creates an empty file or update an existing file's modification date.Local variablesThese variables are available to the current shell process only Environment variablesThese variables are available both in a specific shell session and in sub processes spawned from that shell sessio distributiona bundle that consists of a Linux kernel and a selection of applications that are maintained by a company or user community

Started in 1994 and re-branded in 2003 CentOSDistro that uses the freely available source code of Red Hat Enterprise Linux and compiles it to a distribution which is available completely free of charge, but in return does not come with commercial support.FedoraThe BLANK project was founded in 2003 and creates a Linux distribution which is aimed at desktop computers. Red Hat initiated and maintains the Fedora distribution ever since.rpmAll Red Hat based distributions use the package format SUSE Linuxmostly known for its YaST configuration tool. This tool allows administrators to install and configure software and hardware, set up servers and networks.Embedded systemsa combination of computer hardware and software designed to have a specific function within a larger system

• Ubuntu is recommended for beginners because of its

ease of use and on the other hand Debian is recommended for more advanced users.

• Debian is considered to be more stable compared to

Ubuntu.How is Debian GNU/Linux different from Ubuntu? Name two aspects.

• cost,
• performance
• scalability,
• stability
• hardware demand of the system.

You are planning to install a Linux distribution in a new environment. Name 5 things that you should consider when choosing a distribution.

• Cost
• Scalability
• Backup/Recovery

Explain three major advantages of cloud computing.

• Writer
• Calc
• Impress
• Draw
• Math
• Base

The main applications offered by OpenOffice/LibreOffice are:

BlenderA 3D renderer to create animations. Blender can also be used to export 3D objects to be printed by a 3D printer.GIMPA full-featured image editor, which can be compared with Adobe Photoshop, but has its own concepts and tools to work with images. It can be used to create, edit and save most bitmap files, like JPEG, PNG, GIF, TIFF and many others.InkscapeA vector graphics editor, similar to Corel Draw or Adobe Illustrator. Inkscape’s default format is SVG, which is an open standard for vector graphics. SVG files can be opened by any web browser and, due to its nature as a vector graphic, it can be used in flexible layouts of web pages.AudacityAn audio editor. It can be used to filter, to apply effects and to convert between many different audio formats, like MP3, WAV, OGG, FLAC, etc.ImageMagickA command line tool to convert and edit most image file types. It can also be used to create PDF documents from image files and vice versa.

The most popular open source relational databases are:

The NFS protocolThe standard way to share file systems in networks equipped only with Unix/Linux machines SambaIf there are other types of operating systems attached to the network, it is recommended to use a data sharing protocol that can be understood by all of them. This requirement is fulfilled by BLANK.ownCloud and NextcloudIf the goal is to implement a cloud computing solution able to provide various

methods of web based data sharing, two alternatives should be considered:

JavaScriptBLANK is a programming language mostly used in web pages. In its origins, BLANK applications were very simple, like form validation routines. As for today, BLANK is considered a first class language and it is used to create very complex applications not only on the web, but on servers and mobile devices.
