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.
Depends on your operating system. For any system not Chrome OS, folder creation is an organizational must. Your hard drive stores data sequentially in the form of bits. Whenever you want to access information on your hard drive, the drive has to, much like an array in programming, run through all the data until it comes across the desired file. This, as you could probably imagine, is cumbersome. We, as the users, have the luxury of not having to deal with that kind of information acquisition. We can create folders and directories into which we can place files. The reason I mentioned Chrome OS earlier, was because Chrome OS stores just about everything in the cloud. There isn't any real need to create directories on a Chrome system because all of that data can be managed and stored on Google's servers, as opposed to in files and organized by yourself.
