Study Notes
Application Installation Considerations
- Applications extend and customize operating system functionality.
- They are available from developers or app stores.
- Not all applications run on every OS.
Processor Support
- The processor type (32-bit or 64-bit) significantly affects application compatibility.
- 32-bit OS can address around 4 billion values of memory (4 GB).
- 64-bit OS can reference over 18 quintillion values.
- 64-bit OS can theoretically support over 17 billion GB of memory.
- Many OSs have logical limits on maximum supported memory.
Driver Compatibility
- Hardware drivers must match the OS version (32-bit driver for 32-bit OS, etc.).
- A 64-bit OS can run both 64-bit and 32-bit applications (backwards compatibility).
- Windows stores 32-bit applications in "Program Files (x86)" and 64-bit applications in "Program Files".
Graphics Processor (GPU)
- Integrated graphics share CPU and system memory (common in laptops).
- Discrete (dedicated) graphics cards have their own processors and video memory for high-end applications.
- Check application documentation to determine if an integrated or discrete GPU is needed.
Random Access Memory (RAM)
- RAM is critical as applications and their data execute within it.
- Insufficient RAM prevents application use.
- Total RAM needed is the sum of OS and application requirements.
Central Processing Unit (CPU)
- CPU clock speed (e.g., 3.5 GHz) indicates the relative computing capability.
- There are other criteria to determine the speed of processors, but it is a good starting point.
- CPU requirements vary based on the application (word processing vs. video editing).
Hardware Tokens for Licensing
- Some applications use USB hardware tokens to ensure license compliance.
- The application only runs if the token is present.
- Common for high-end, expensive software.
Storage Space
- Application requirements specify needed free disk space.
- Some applications require a large amount of drive space.
- It's important to know the storage requirements before installation.
Software Acquisition
- Software is now mainly acquired via download from developers or trusted app stores.
- Avoid untrusted third-party sources.
- Media is needed to install software on systems without internet access.
- Optical media (DVD-ROM) or USB drives can be used.
ISO Files
- ISO files are a standard format for storing the contents of an entire optical drive.
- ISO 9660 is the standard file system for optical drives, standardized by the International Organization for Standardization (ISO).
- An ISO file is a sector-by-sector copy of the optical drive.
- Modern file systems recognize ISO files, and mounting them displays the original file structure.
Security Considerations
- Applications run with the user's rights and permissions.
- Poorly written or malicious applications can cause problems, because it has the same permissions you do on your machine.
- Upgrading applications can cause issues, requiring downgrades or restoration from backups.
- New applications can slow down systems or delete data.
Network Impact
- Installed applications can communicate with other systems on the network.
- They have the same rights and permissions to access network file shares as the user.
Business Impact
- Application problems can disrupt tasks, timelines, and business operations.
- Updated applications may require user retraining due to changes in UI or workflow.
- Downtime and outages due to application issues can negatively impact a business.
- Testing and rollback plans are crucial when installing or upgrading applications.
