Final answer:
To check if an application is 32-bit or 64-bit, on Windows, you can use the properties menu or Task Manager, and on Mac, you can use the 'Get Info' option. Command-line tools can be used for various operating systems as well.
Step-by-step explanation:
To determine if an application is 32-bit or 64-bit, you can use various methods depending on your operating system. On Windows, you can check the application's properties by right-clicking on the executable file and selecting 'Properties', followed by the 'Compatibility' tab. If the application is running on a 64-bit system, you might see a mention of 32-bit there if it's a 32-bit application. Additionally, in the Task Manager under the 'Details' or 'Processes' tab, 32-bit applications might be listed with '*32' next to their name. On Mac OS, you can check an application's information by using the 'Get Info' option after right-clicking on the application in Finder. Look for information about the application type to see if it's 64-bit or 32-bit. Using command-line tools such as 'file' on Linux can also tell you whether a binary is 32-bit or 64-bit.
