Good Morning, I was wondering if I could get some assistance with these computer science concepts. Thank you in advance!


Module 4 - Case

 

INSTALLING AND CONFIGURING UBUNTU

 

What is Linux?

 

Ubuntu is built on the foundation of Linux, which is a member of the Unix family. Unix is one of the

 

oldest types of operating systems, and together with Linux has provided reliability and security for

 

professional applications for almost half a century. Many servers around the world that store data for

 

popular websites (such as YouTube and Google) run some variant of Linux or Unix. The popular Android

 

system for smartphones is a Linux variant; modern in-car computers usually run on Linux. Even Apple OS

 

x is based on Unix. The Linux kernel is best described as the core?almost the brain?of the Ubuntu

 

operating system.

 

The Linux kernel is the controller of the operating system; it is responsible for allocating memory and

 

processor time. It can also be thought of as the program which manages any and all applications on the

 

computer itself. While modern graphical desktop environments have generally replaced early command

 

line interfaces, the command line can still be a quick and efficient way of performing many tasks.

 

Linux was designed from the ground up with security and hardware compatibility in mind, and is

 

currently one of the most popular Unix-based operating systems. One of the benefits of Linux is that it is

 

incredibly flexible and can be configured to run on almost any device?from the smallest microcomputers and cellphones to the largest super-computers. Unix was entirely command line-based until

 

graphical user interfaces (GUIs) emerged in 1973 (in comparison, Apple came out with Mac os ten years

 

later, and Microsoft released Windows 1.0 in 1985).

 

The early GUIs were difficult to configure, clunky, and generally only used by seasoned computer

 

programmers. In the past decade, however, graphical user interfaces have grown in usability, reliability,

 

and appearance. Ubuntu is one of many different Linux distributions.

 

Installation

 

1. Getting Ubuntu

 

Before you can get started with Ubuntu, you will need to obtain a copy of the Ubuntu installation image

 

for DVD or USB. Some options for doing this are outlined below.

 

2. Minimum system requirements

 

If you are unsure whether it will work on your computer, the Live DVD is a great way to test things out

 

first. Below is a list of hardware specifications that your computer should meet as a minimum

 

requirement. 1 GHz x86 processor (Pentium 4 or better) 1 gb of system memory (RAM) 5 gb of disk space (at least 15 gb is recommended) Video support capable of 1024?768 resolution Audio support 3. Downloading Ubuntu

 

The easiest and most common method for getting Ubuntu is to download the Ubuntu DVD image

 

directly from http://www.ubuntu.com/download.

 

Choose how you will install Ubuntu: Download and install Try it from a DVD or USB stick 3.1.Download and Install/Try it from a DVD or USB stick

 

For the Download and install, or Try it from a DVD or USB stick options, select whether you require the

 

32-bit or 64-bit version (32-bit is recommended for most users), then click ?Start download.?

 

32-bit vs. 64-bit

 

Ubuntu and its derivatives are available in two versions: 32-bit and 64-bit. This difference refers to the

 

way computers process information. Computers capable of running 64-bit software are able to process

 

more information than computers running 32-bit software; however, 64-bit systems require more

 

memory in order to do this. Nevertheless, these computers gain performance enhancements by running

 

64-bit software. If your computer has a 64-bit processor, install the 64-bit version. If your computer is older, a netbook, or you do not know the type of processor in the computer,

 

install the 32-bit version. If your computer has a 64-bit processor, select the ?64-bit? option before you click ?Start download.?

 

4. Burning the DVD image

 

Once your download is complete, you will be left with a file called ubuntu-14.04-desktop-i386.iso or

 

similar (i386 here in the filename refers to the 32-bit version. If you downloaded the 64-bit version, the

 

filename contains amd64 instead). This file is a DVD image?a snapshot of the contents of a DVD?which

 

you will need to burn to a DVD.

 

5. Creating a bootable USB drive

 

If your PC is able to boot from a USB stick, you may prefer to use a USB memory stick instead of burning

 

a DVD. Scroll down to ?Burn your DVD or create a USB drive,? select DVD or USB stick, choose the OS you

 

are using to create the USB drive, and then click Show me how. If you select the ?USB Stick? option, your

 

installation will be running from the USB memory stick. In this case, references to Live DVD, will refer to

 

the USB memory stick.

 

6. Trying out Ubuntu

 

The Ubuntu DVD and USB stick function not only as installation media, but also allow you to test Ubuntu

 

without making any permanent changes to your computer by running the entire operating system from

 

the DVD or USB stick. Your computer reads information from a DVD at a much slower speed than it can read information off of

 

a hard drive. Running Ubuntu from the Live DVD also occupies a large portion of your computer?s

 

memory, which would usually be available for applications to access when Ubuntu is running from your

 

hard drive. The Live DVD/USB experience will therefore feel slightly slower than it does when Ubuntu is

 

actually installed on your computer. Running Ubuntu from the DVD/USB is a great way to test things out

 

and allows you to try the default applications, browse the Internet, and get a general feel for the

 

operating system. It?s also useful for checking that your computer hardware works properly in Ubuntu

 

and that there are no major compatibility issues.

 

To try out Ubuntu using the Live DVD/USB stick, insert the Ubuntu DVD into your DVD drive, or connect

 

the USB drive and restart your computer. After your computer finds the Live DVD/USB stick, and a quick

 

loading screen, you will be presented with the ?Welcome? screen. Using your mouse, select your

 

language from the list on the left, then click the button labelled Try Ubuntu. Ubuntu will then start up,

 

running directly from the Live DVD/USB drive.

 

Once Ubuntu is up and running, you will see the default desktop. Feel free to test things out. Open some

 

applications, change settings and generally explore?any changes you make will not be saved once you

 

exit, so you don?t need to worry about accidentally breaking anything.

 

When you are finished exploring, restart your computer by clicking the ?Power? button in the top right

 

corner of your screen (a circle with a line through the top) and then select Restart. Follow the prompts

 

that appear on screen, including removing the Live DVD and pressing Enter when instructed, and then

 

your computer will restart. As long as the Live DVD is no longer in the drive, your computer will return to

 

its original state as though nothing ever happened! 7. Installing Ubuntu?Getting started

 

At least 5 DB of free space on your hard drive is required in order to install Ubuntu. We recommend 15

 

gb or more. This will ensure that you will have plenty of room to install extra applications later on, as

 

well as store your own documents, music, and photos. To get started, place the Ubuntu DVD in your DVD

 

drive and restart your computer. Your computer should load Ubuntu from the DVD. When you first start

 

from the DVD, you will be presented with a screen asking you whether you want to first try out Ubuntu

 

or install it. Select the language you want to view the installer in and click on the Install Ubuntu button.

 

This will start the installation process.

 

If you have an Internet connection, the installer will ask you if you would like to ?Download updates

 

while installing.? We recommend you do so. The second option, ?Install this third-party software,?

 

includes the

 

Fluendo MP3 codec, and software required for some wireless hardware. If you are not connected to the

 

Internet, the installer will help you set up a wireless connection.

 

The ?Preparing to install Ubuntu? screen will also let you know if you have enough disk space and if you

 

are connected to a power source (in case you are installing Ubuntu on a laptop running on battery). Once

 

you have selected your choices, click Continue. Internet connection

 

If you are not connected to the Internet, the installer will ask you to choose a wireless network (if

 

available).

 

1. Select Connect to this network, and then select your network from the list.

 

2. If the list does not appear immediately, wait until a triangle/arrow appears next to the

 

network adapter, and then click the arrow to see the available networks.

 

3. In the Password field, enter the network wep or wpa key (if necessary).

 

4. Click Connect to continue. Allocate drive space

 

The Ubuntu installer will automatically detect any existing operating system installed on your machine,

 

and present installation options suitable for your system. The options listed below depend on your

 

specific system and may not all be available:

 

? Install alongside other operating systems

 

? Upgrade Ubuntu ? to 14.04

 

? Erase ? and install Ubuntu

 

? Something else

 

Install alongside other operating systems.

 

For more complicated dual-booting setups, you will need to configure the partitions manually. Upgrade Ubuntu ? to 14.04

 

This option will keep all of your Documents, music, pictures, and other personal files. Installed software

 

will be kept when possible (not all your currently installed software may be supported on the new

 

version). System wide settings will be cleared.

 

Erase disk and install Ubuntu

 

Use this option if you want to erase your entire disk. This will delete any existing operating systems that

 

are installed on that disk, such as Microsoft Windows, and install Ubuntu in its place. This option is also

 

useful if you have an empty hard drive, as Ubuntu will automatically create the necessary partitions for

 

you.

 

Formatting a partition will destroy any data currently on the partition. Be sure to back up any data you

 

want to save before formatting. More information and detailed instructions on partitioning are available

 

at: https://help.ubuntu.com/community/HowtoPartition.

 

After you have chosen the installation type, click Continue, or Install Now.

 

Confirm Partition choices and start install

 

If you chose Something else, configure the partitions as you need. Once you are happy with the way the

 

partitions are going to be set up, click the Install Now button at the bottom right to move on. To reduce the time required for installation, Ubuntu will continue the installation process in the

 

background while you configure important user details?like your username, password, keyboard

 

settings and default time zone.

 

Where are you?

 

The next screen will display a world map. Using your mouse, click your geographic location on the map

 

to tell Ubuntu where you are. Alternatively, you can type your location in the field below the map. This

 

allows Ubuntu to configure your system clock and other location-based features. Click Continue when

 

you are ready to move on. Keyboard layout

 

Next, you need to tell Ubuntu what kind of keyboard you are using. In most cases, you will find the

 

suggested option satisfactory. If you are unsure which keyboard option to select, you can click the Detect

 

Keyboard Layout button to have Ubuntu determine the correct choice by asking you to press a series of

 

keys. You can also manually choose your keyboard layout from the list of options. If you like, enter text

 

into the box at the bottom of the window to ensure you are happy with your selection, then

 

click Continue. Who are you?

 

Ubuntu needs to know some information about you so it can set up the primary user account on your

 

computer. When configured, your name will appear on the login screen as well as the user menu.

 

On this screen you will need to tell Ubuntu: your name what you want to call your computer your desired username your desired password how you want Ubuntu to log you in Enter your full name under Your name. The next text field is the name your computer uses, for terminals

 

and networks. You can change this to what you want, or keep the predetermined name. Next is your

 

username, the name that is used for the user menu, your home folder, and behind the scenes. You will

 

see this is automatically filled in for you with your first name. Most people find it easiest to stick with

 

this. However, it can be changed if you prefer.

 

Next, choose a password and enter it into both password fields. When both passwords match, a strength

 

rating will appear to the right that will show you whether your password is ?too short,? ?weak,? ?fair,? or

 

?strong.? You will be able to continue the installation process regardless of your password strength, but

 

for security reasons it is best to choose a strong one. This is best achieved by having a password that is at

 

least six characters long, and is a mixture of letters, numbers, symbols, and uppercase/lowercase. Avoid

 

obvious passwords that include your birth date, spouse?s name, or the name of your pet.

 

Login Options

 

Finally, at the bottom of this screen you have two options regarding how you wish to log in to Ubuntu.

 

You may also choose to have Ubuntu encrypt your home folder. Log in automatically Require my password to log in

 

o Encrypt my home folder Log in automatically

 

Ubuntu will log in to your primary account automatically when you start up the computer so you won?t

 

have to enter your username and password. This makes your login experience quicker and more

 

convenient, but if privacy or security is important to you, we don?t recommend this option.

 

Anyone who can physically access your computer will be able to turn it on and also access your files.

 

Require my password to login

 

This option is selected by default, as it will prevent unauthorized people from accessing your computer

 

without knowing the password you created earlier. This is a good option for those who, for example,

 

share their computer with other family members. Once the installation process has been completed, an

 

additional login account can be created for each family member. Each person will then have their own

 

login name and password, account preferences, Internet bookmarks, and personal storage space.

 

Encrypt my home folder

 

This option provides you with an added layer of security. Your home folder is where your personal files

 

are stored. By selecting this option, Ubuntu will automatically enable encryption on your home folder,

 

meaning that files and folders must be decrypted using your password before they can be accessed.

 

Therefore if someone had physical access to your hard drive (for example, if your computer was stolen

 

and the hard drive removed), they would not be able to see your files without knowing your password.

 

If you choose this option, be careful not to enable automatic login at a later date. It will cause

 

complications with your encrypted home folder, and will potentially lock you out of important files.

 

Finishing Installation

 

Ubuntu will now finish installing on your hard drive. As the installation progresses, a slideshow will give

 

you an introduction to some of the default applications included with Ubuntu. The slideshow will also

 

highlight the Ubuntu support options.

 

After approximately twenty minutes, the installation will complete and you will be able to click Restart

 

Now to restart your computer and start Ubuntu. The DVD will be ejected, so remove it from your DVD

 

drive and press Enter to continue.

 

Wait while your computer restarts, and you will then see the login window (unless you selected

 

automatic login). Login Screen

 

After the installation has finished and your computer is restarted, you will be greeted by the login screen

 

of Ubuntu. The login screen will present you with your username and you will have to enter the

 

password to get past it. Click your username and enter your password. Once done, you may click the

 

arrow or press Enter to get into the Ubuntu desktop. Ubuntu?s login screen supports multiple users and

 

also supports custom backgrounds for each user. In fact, Ubuntu automatically will pick up your current

 

desktop wallpaper and set it as your login background. The login screen allows you to update your

 

keyboard language, volume intensity and enable/disable accessibility settings before you log in to your

 

desktop. It also displays date/time and battery power for laptops. You can also shut down or restart your

 

system from the login screen.
