Module 5.4- Managing Software

Question 1

How Software Installation works

Answer 1

• when you install software, the OS places the necessary files in specific locations on your computer’s storage, such as the Program Files directory in Windows or the Applications folder on macOS
• OS also updates its registry or file system to ensure software runs correctly
• Download or Insert Installation Media- software can be installed via a downloadable installer from the internet or using physical media like a CD/DVD or USB drive
• Run the Installer- double-click the installer file e.g., exe for Windows, dmg for macOS to start the installation process
• Follow the Setup Instructions- you’ll typically see prompts to agree to terms and conditions, select installation locations, and customise your setup

Complete the Installation- after following the steps, the installer copies files to the appropriate locations and configures the software for use; once completed, the software is ready to run

Question 2

Common Installation Methods

Answer 2

• there are different ways to install software, depending on the OS and how the application is distributed

1. Direct Download from the Web
2. Package Managers (Linux and macOS)
3. Linux Package Managers
4. Homebrew (macOS)
5. App Stores
6. Microsoft Store (Windows)
7. Enterprise Deployment Tools
8. Microsoft Endpoint Configuration Manager (formerly SCCM)
9. Group Policy (Windows)

Question 3

Direct Download from the Web

Answer 3

• most modern software is distributed via direct download from the web
• users can visit a company’s website or a software marketplace (like Microsoft Store or Mac App Store) to download and install applications
• e.g. if you want to install Zoom for video conferencing, you simply go to the Zoom website, download the installer, and follow the setup instructions

Question 4

Package Managers (Linux and macOS)

Answer 4

• for Linux and macOS users, package managers are a convenient way to install software
• a package manager automatically downloads, installs, and updates software using simple commands in the terminal or through graphical interfaces

Question 5

Linux Package Managers

Answer 5

• tools like APT (Advanced Package Tool) for Ubuntu/Debian or YUM for Red Hat-based distributions handle the entire installation process via command lines e.g. sudo, apt, install, vic

Question 6

Homebrew (macOS)

Answer 6

• this package manager allows macOS users to install software through the terminal e.g. brew install git, especially useful for developers and tech enthusiasts
• e.g. if you’re using Linux, you can install VLC Media Player by typing ‘sudo apt install vlc’, and the system will handle downloading, unpacking, and setting up the software

Question 7

App Stores

Answer 7

• many OSs, especially mobile platforms like iOS and Android, rely on app stores for software distribution
• app stores ensure that all applications have been vetted for security and compatibility
• Microsoft Store (Windows), Mac App Store, Google Play Store (Android), and Apple App Store (iOS) allow users to browse, download, and install apps with one click, while handling updates automatically
• e.g. to install Microsoft Teams on your Windows device, you can search for it in the Microsoft Store, click install, and let the store manage the process

Question 8

Enterprise Deployment Tools

Answer 8

• in business environments, companies often use enterprise software deployment tools to automate and control the installation of software across multiple devices

Question 9

Microsoft Endpoint Configuration Manager (formerly SCCM)

Answer 9

• allows IT departments to push software installations to users’ systems remotely

Question 10

Group Policy (Windows)

Answer 10

• IT administrators can use Group Policy to automatically install or restrict applications on a network of computers

Question 11

Uninstalling Software

Answer 11

• uninstalling software removes the program files, settings, and registry entries associated with the application
• different OSs offer various methods for uninstalling software

Question 12

Uninstalling Software on Windows

Answer 12

• in Windows, most common way to uninstall software is through Control Panel

1. open the Control Panel and go to Programs and Features
2. find the software you want to uninstall in the list, click on it, and select Uninstall
3. follow the prompts to remove the application

• Settings App- alternatively, you can uninstall apps directly from the Settings menu under Apps & Features

Question 13

Uninstalling on macOS

Answer 13

• drag to trash- on macOS, uninstalling applications is often as simple as dragging the application from the Applications folder to the Trash

1. open the Applications folder
2. drag the app you want to uninstall to the Trash
3. empty the Trash to fully remove the program- some applications come with their own uninstallers, which are found in the apps folder or by right-clicking the app and selecting Move to Trash

Question 14

Uninstalling with Package Manager

Answer 14

• on Linux, removing software typically involves using a package manager, like APT or YUM, to uninstall programs via the terminal
• e.g. use the command sudo apt remove vic to uninstall VLC Media Player

Question 16

Using Third-Party Uninstallers

Answer 16

• for a more thorough removal, especially with programs that leave behind unwanted files or registry entries, you can use third-party uninstallers like:
• Revo Uninstaller (Windows)- helps ensure that all associated files and registry entries are completely removed after uninstallation
• AppCleaner (macOS)- a free tool that finds and removes leftover files after dragging an app to the Trash

Question 17

Keeping Software Up To Date

Answer 17

• regular updates are essential for maintaining the security, performance, and functionality of your software
• updates can include new features, performance improvements, bug fixes, and-most importantly-security patches that protect your system from vulnerabilities

Question 18

Why are Updates important?

Answer 18

• Security- many updates contain patches for newly discovered security vulnerabilities
• without these updates, your system could be exposed to cyberattacks or malware
• Performance Enhancements- updates often include performance improvements, ensuring the software runs more smoothly and efficiently
• New Features- software developers regularly add new features to keep their products competitive
• keeping your software updated ensures you’re always using the most current version with the latest tools
• Bug Fixes- updates often address bugs or glitches in the software, improving overall stability and reducing crashes or errors
• e.g. when a major security vulnerability is discovered in a popular software like Adobe Acrobat or Microsoft Office, the developers quickly release a patch through an update- installing these updates protects you from potential cyber threats
