System requirements
System requirements refer to a checklist of minimum necessary items for a computer to have. These items would be requirements in order for an operating system to work, such as Windows XP. If the system did not have these things, the computer or operating system might crash or cause problems. If it exceeds minimum expectations, you could check the recommended system requirements, and see if it also meets those. If it does not, it is not bad. But if it does meet the recommended requirements, that is very good to know.
