Hardware, Software, and Computer Management (Grade 11 NSC Matric Computer Application Technology): Revision Notes
Software Installation
Introduction
When you need new software on your computer, you'll first need to work out what requirements are necessary before beginning the installation process. Once you've determined this, you have two main options for getting the software:
- Download the software files from a website
- Purchase a CD or DVD from a store
After obtaining the installation files, you can run the installation process. Most software includes an installation wizard that guides you through each step of setting up the programme on your computer.
Before installing any software, check your computer's system requirements including available storage space, operating system compatibility, and hardware specifications to ensure the software will run properly.
Online download
The most common way to get new software today is downloading it directly from the internet. This method is convenient and often immediate, but requires some important safety considerations.
Getting software from the internet
To download software safely, you must visit the official website where the software is available.
Always download software from trusted publishers or verified retailers only. This ensures you're getting legitimate software and helps prevent accidentally downloading malware or viruses onto your computer.
When you find the software you want, you'll typically use a credit card to purchase it. Once you've completed the payment, you can click the download link to begin transferring the files to your computer.
App stores and software categories
You can also purchase software from dedicated app stores, such as:
- Google's Play Store
- Apple's App Store
- Windows Store
These platforms organise software by category, making it easier to find what you need. Common categories include gaming, word processing, and design software.
Example: downloading Chrome
Worked Example: Downloading Chrome Browser
Here's how downloading works in practice using Chrome as an example:
Step 1: Visit the official website (https://www.google.com/chrome/ for Chrome)
Step 2: Click the Download button - a dialogue box will appear asking you to accept the Terms of Service
Step 3: Make sure you're downloading the correct version for your computer system
Step 4: Follow the on-screen instructions to complete the installation
Step 5: Once installed, you can access the application from your Start menu
Portable storage medium installation
Some software still comes on physical media like CDs or DVDs. This includes programmes such as:
- Operating systems
- Microsoft Office (the traditional version, not Office 365)
- Some computer games
To install software from a CD or DVD, you need to visit a store to purchase the physical product. When you get home, insert the disc into your computer's optical drive (CD or DVD player). The installation programme usually starts automatically, but you can also manually run the setup programme to begin installation.
Physical media installation is becoming less common as internet speeds have improved and digital downloads have become the preferred method for most software distribution.
How to install software
Whether you've downloaded files or inserted a disc, the installation process follows a similar pattern. An installation wizard guides you through the necessary steps, though the specific details may vary between different programmes.
Installation wizard steps
The installation process typically begins when you click on the downloaded file or insert the disc. You'll then run the setup programme (usually called Setup.exe or Install.exe). Here's what each step involves:
Accept the licence agreement Most software requires you to agree to the manufacturer's terms of use before installation can continue. This licence agreement is a legally binding contract that outlines what you can and cannot do with the software. Read through this carefully before accepting.
Enter the product key The product key connects the software to your specific purchase. This prevents the software from being installed on more devices than the licensing terms allow and helps prevent piracy. The key also links you to online support services if available.
Choose installation location
The installer suggests a default folder for storing the programme files, usually on your C:/ drive. It's generally best to accept this suggestion unless you have specific storage requirements. Knowing where your software is installed helps you locate programmes later.
Choose installation type Most installers offer different installation options:
- Typical installation: Installs the most commonly used components
- Custom installation: Lets you choose which specific components to install
- Full installation: Installs all available software components
Install extras Some software comes bundled with additional programmes (such as antivirus software with Microsoft products). These extras are often selected by default, so you'll need to uncheck them if you don't want them installed. Always review what additional software is being installed.
Watch out for bundled software! Many free programmes try to install additional software you didn't ask for. Always read each installation screen carefully and uncheck any extras you don't want.
Check for updates After installation, the installer may ask if you want to check for the latest version. This is usually a good idea for disk-based software, as downloaded software is often more current.
Register your product
Some programmes ask you to register on their online portal. This allows the company to contact you with news and update notifications. You can usually skip this step if you don't want to be contacted.
Add shortcuts The final step typically offers to create a shortcut on your desktop for easy access to the programme. You can choose to decline this if you prefer to keep your desktop uncluttered.
Take a tour Many programmes offer an introductory tutorial when you first open them. These tutorials highlight important features and explain how to use the software effectively. If you're using the programme for the first time, working through the tutorial can save you time later.
How to uninstall software
Uninstalling software means completely removing a programme and all its associated files from your computer. This is important for freeing up storage space and keeping your system running efficiently.
Uninstalling in Windows 10
To uninstall a programme in Windows 10:
Step 1: Click on the Windows icon in the bottom-left corner
Step 2: Click on Settings (the gear icon)
Step 3: Click on Apps
Step 4: Click on "Apps & Features" in the left panel to see all installed applications
Step 5: Find the programme you want to remove and click the "Uninstall" button (note: if this button appears greyed out, it means the programme is a system app that cannot be removed)
Step 6: Click "Uninstall" in the confirmation dialogue that appears and wait for the system to remove the application
The uninstall process will remove the programme and its related files from your computer, freeing up storage space.
Some programmes may leave behind configuration files or user data even after uninstalling. For a complete clean removal, you might need to manually delete these remaining files from your user folders.
Remember!
Key Points to Remember:
- Safety first: Only download software from trusted publishers or verified retailers to avoid malware
- Two main methods: You can install software either by downloading from the internet or using CDs/DVDs
- Installation wizard: Most software uses a step-by-step wizard to guide you through setup - read each step carefully
- Choose your options: Pay attention to licence agreements, installation locations, and bundled extras during setup
- Complete removal: Use Windows Settings > Apps to properly uninstall programmes and free up storage space
