Why is it important to know the minimum CPU requirements for an application?
To ensure the application runs smoothly and efficiently
What type of software commonly uses an external hardware token for licensing?
High-end software with a high price tag
What is the purpose of confirming that an application is being used appropriately by developers?
To ensure valid licensing and usage
What is a consideration when installing applications that use a large amount of drive space?
The amount of free disk space required
What type of file is an ISO file?
A sector-by-sector copy of an optical drive
What standard file system is used to format optical drives?
ISO 9660
What happens when you double-click on an ISO file?
It displays the original optical drive's file structure
Why is it important to be cautious when installing applications on a system?
To ensure applications don't have more access than necessary
What should you do if an application upgrade causes problems?
Downgrade the application or reinstall from a known good backup
What can happen if a new application is poorly written or contains malicious software?
It may slow down the system
How can installing an application impact connected network systems?
It allows the application to communicate with other systems on the network
Why might users need retraining when an application is updated?
Due to changes in user interface or workflow
Study Notes
- Operating systems can be extended with applications, available from app stores or developers.
- Applications may not run on every operating system due to processor type and architecture.
- Processor type affects the amount of memory that can be accessed: 32-bit supports up to 4 billion values, while 64-bit supports over 18 quintillion values.
- When installing hardware drivers, they must match the operating system's version (32-bit or 64-bit).
- 32-bit operating systems cannot run 64-bit applications, while 64-bit operating systems can run both 32-bit and 64-bit applications.
- Applications are stored in specific folders depending on their architecture (32-bit in "x86," 64-bit in "program files").
- Integrated graphics processors in systems use common system memory, but high-end applications may require dedicated (discrete) graphics cards.
- Random access memory (RAM) is a critical specification for applications, as they must execute inside this memory; a 32-bit operating system and a RAM-intensive application may require a total of 8GB for instance.
- CPU clock speed is a starting point for determining relative processor power, but other factors also influence it.
- Some applications use external hardware tokens, such as USB keys, for licensing, ensuring that only those with the key can run the software.
- Applications require free space for installation, with some taking up a significant amount of drive space.
- Prior to the internet, software was acquired physically and installed from optical media (CDs, DVDs) or ISO files.
- ISO files are sector-by-sector copies of optical media, and they can be recognized by most modern file systems.
Learn about how processor speed can determine the performance of a computer, and how it is a key factor when assessing different processors. Discover the importance of referencing application specifications to determine the minimum required CPU for specific tasks.
