The two different types of system software are single program and multitasking.
1. Single program: The single program software allows only a single program at a time. For example if you are using spreadsheet and you want to write a memo. At that time the single program does not allow the word processor to write a memo. You must shut down the spreadsheet and than use the word processor.
2. Multi-tasking: This type of system software is the simple and better way. You can run different tasks at a time. It is easy to copy the data from one to another. If your computer has multiple CPUs you can also run multiprocessing.
