Each object that is created while a program is running takes up memory. Running low on memory is a problem. It will cause a Mac app to perform badly and will cause an iOS app to crash. This is why it is essential that any objects that are no longer necessary are destroyed so that their memory can be reclaimed and used. Bits is the amount of memory a CPU has. The more memory (bits) a CPU has, the bigger the programs it can handle.
