P.M. memory includes RAM and ROM, which is temporary and permanent both.
S.M. memory is just permanent memory which is used for the future.
P.M. memory is used for the present work.
primary memory stores the necessary programmes or system software which are required to execute application programs while secondary memory is needed to bulk storage of programs and data .
There is two difference between them. 1. The not null constraint is by default added to primary key, it means, primary key attribute cannot accept null values, whereas, the attribute declared as unique can accept null values. It is the major difference between the two. 2. Secondly, we can have only one primary key in a relation, whereas, multiple attributes can be declared unique at the same time.

They are both storage devices
Cache memory is smaller and quicker, primary memory larger and slower.
Usually the hard drives are considered secondary. The RAM (Random Access Memory) is the primary memory.
Computer memory is categorized into primary and secondary memory. While primary memory is the main memory of the computer which is used to store data or information temporarily, whereas secondary memory refers to external storage devices that are used to store data or information permanently.
Intenal memory is only primary memory. The term secondary memory is used for External storage like hard disk etc.
No, Because secondary takes more time as compared to primary. primary takes less time as compared to secondary.
primary memory consist of RAMsecondary memory consist of ROM
secondary memory is actually the permanent memory/the backing storage of the computer. it is of two types:sequential accessdirect accessauxiliary memory is the computer's internal/temporary memory. it is also of two types:random access memory (RAM)read only memory (ROM)the difference between secondary memory and auxiliary memory is that:-both are same i.e both performs the same operationsthanks.
Well for mac you can only back up your data when you have a secondary storage hard drive, for windows it gives you more space to download and to use it, basic
You have to keep on remebering the memory
