What is the difference between main and auxiliary memory?
The major difference between main memory and auxiliary memory is that main memory is directly accessed by CPU but the auxiliary memory is not accessed by the CPU directly.For this the data is first transferred to main memory from auxiliary memory and then from main memory the data is transferred to the CPU for further processing.

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.
What is auxiliary memory give an example of auxiliary memory?
The major difference between main memory and auxiliary memory is that main memory is directly accessed by CPU but the auxiliary memory is not accessed by the CPU directly.For this the data is first transferred to main memory from auxiliary memory and then from main memory the data is transferred to the CPU for further processing. Some examples of auxiliary memory would be disks, external hard drives, USB drives, etc.
Does rom a primary storage?
Yes. ROM (Read Only Memory) is a primary memory. BIOS is a Read Only Memory and is directly accessed by the cpu just like RAM (Random Access Memory). So it is a primary storage.
What are the organization that use the magnetic disk as secondary storage device?
Um, your question doesn;t make much sense.. Secondary storage in normally considered your computers hard drive, a flash drive, floppy disc and the like. Things that don't lose data when turned off. Primary storage (like system memory)is accessed directly by your CPU, secondary storage is normally accessed through some soft or I/O device.
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
Is cache memory a form of read only that can be accessed more quicky by the CPU?
yes
What is the function of CPU cache?
Many CPUs have what is known as a CPU cache. The function of this CPU cache is to speed up access to data.
Describe different types of primary and secondary memory of a computer?
Primary memory is that which is directly connected to the motherboard for the CPU to process, meaning your RAM modules. Secondary memory is located on the hard drive in a virtual memory (called a page file or swap file) when the RAM modules have no more room to store data that is still running, but still needs to recall some as soon as it can swap out what processes have the higher priority. When the RAM and page file are full, you will notice a lag in computer performance as it struggles to process so much data at one time. If it exceeds the limits of your memory and processor, the system may crash. A fixed large swap file and more memory makes the CPU work less and a better, faster CPU will keep the memory demands lower. This is why more memory and a faster CPU is needed for more complex data processing. To reduce processing even further, a dedicated graphics card with it's own memory and built in CPU that handles the graphic processing allows for the RAM and CPU to work much less, making the computer much more faster.
What is the purpose of memory?
The purpose of secondary memory is storage of data that is not immediately needed for processing by the CPU. Examples of secondary devices are hard drives and optical drives.
Is RAM stored directly on the CPU?
No. RAM is a type of memory, not data.
Is RAM stored directly on CPU?
No. RAM is a type of memory, not data.
