Differnec between web based and installed based application
Web-based application:
A program that runs in a web browser and needs an internet connection instead of being installed on the device.
Installed-based application:
A program that is downloaded and installed on a device and can usually be used without an internet connection.
Advantages of Web-based Applications
Can be used on any device, anywhere, with internet access
Always up to date (no manual updates needed)
No installation required, saving storage space
Often have lower hardware requirements
Fewer compatibility issues (software runs in the cloud)
Disadvantages of Web-based Applications
Cannot be used without internet access
Performance depends on internet speed and quality
May be slower than desktop applications
Often have fewer features than installed (desktop) versions
Subscription-Based Software (Definition)
Subscription-based software is software that you pay for monthly or yearly to use.
You can only keep using the software while your subscription is active.
Traditional Licensing vs Subscription Software
Traditional licensing
You pay once, upfront
You can use the software indefinitely
Updates are limited or cost extra
Subscription software
You pay monthly or yearly
Access stops if you stop paying
Updates are included automatically
Compatibility (Definition)
Compatibility is the ability of software to work properly with the hardware and software on a computer or device.
Compatibility Between Software Versions
Most software is backward compatible
New versions can open files from older versions
Software is usually not forward compatible
Older versions cannot open files made in newer versions
Saving for Compatibility
Files can often be saved in older formats using Save As
Older versions may not support new features
Important when sharing files with others
System Requirements (Definition)
System requirements are the hardware and software specifications needed for software to run properly.
Minimum vs Recommended Requirements
Minimum requirements: Bare minimum to install and run the software
Recommended requirements: Ensure smooth and effective performance
Always aim for recommended, not minimum
Productivity Software
Productivity software for mobile users includes apps that help people work efficiently while on the move

What Are Software Bugs?
Bugs are mistakes or errors in software that happen accidentally when programmers write the code.
They are not viruses.
Why Bugs Are a Problem
