Main memory is also called primary memory.Main memory is on the semi-conductor chips.These chips are connected with the CPU on the motherboard.Main memory is very fast and it is directly accessible by the CPU.Different types of memory chips are RAM,ROM,PROM,etc.
Secondary memory is also called Backing Storage memory.It is used to enhance the capacity and performance of main memory.Examples of secondary storage are Floppy disks,Magnetic disks,Magnetic tapes,CDs,Hard disks can store a bulk amount of data.

Primary memory refers to the main memory that is directly accessible by the CPU, such as RAM, used for storing data and instructions currently in use by the computer. Secondary memory, like hard drives or SSDs, is used for long-term storage of data and programs even when the system is powered off. Primary memory is faster but has limited capacity, while secondary memory is slower but has greater storage capacity.

What is the difference between primary key and secondary key?
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.
Who originally distinguished between primary memory and secondary memory?
William James
What are the similarities between secondary memory and primary memory pdf?

What is the difference between cache-memory and primary-memory?
Cache memory is smaller and quicker, primary memory larger and slower.
What is meant by secondary computer memory?
Usually the hard drives are considered secondary. The RAM (Random Access Memory) is the primary memory.
Distinguish between primary and secondary 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.
What is the difference between primary and secondary memory?
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.
IS the Internal memory only primary memory or both primary or secondary memory?
Intenal memory is only primary memory. The term secondary memory is used for External storage like hard disk etc.
Can you use secondary memory in place of primary memory?
No, Because secondary takes more time as compared to primary. primary takes less time as compared to secondary.
What does the primary memory and secondary memory consists of?
primary memory consist of RAMsecondary memory consist of ROM
What is the Difference between secondary memory and auxiliary memory?
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.
What are the disadvantage of primary storage?
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
