This is called a key attribute!

There are different types of key attributes!

Primary key is the key that is actually chosen, for example a social security number. 

There is also a unique key, say our finger prints! they also uniquely identify humans, but usually we prefer to use social security number when we list people (a unique key could be a primary key if we chose so)

We could also identify people by their social security number and a name, but this is unnecessary, as social security number already gives a full identification. Such a reduntant key is called super key.

You discover memory is corrupted, what would be an indication of a software vs. a hardware issue?
bearhunter [10]
Hey there!

Memory (RAM) is considered to be hardware since it is a physical component that makes up the computer and is accessed through the CPU rather than internal code that makes the computer run (which is software). Therefore, if you are having issues with the memory, it is likely a problem with a memory chip, making it a hardware issue. 

Hope this helped you out! :-)
