As we know that RAM and ROM both are a type of primary memory.Both of them have own properties :- ROM is permanent in nature i.e It holds data permenently, whereas RAM is a temprory in nature i.e whenever the current is supplies to the RAM, data will be stored on it
RAM (Random Access Memory)
destructive read out memory
By "main memory" I assume you mean Primary Storage. This would be your RAM (Randon Access Memory)
A: They are called RAM or Random access memory
The memory that the computer processor accesses directly is primary memory. It is wired directly to the processor. RAM is primary memory on a computer.
Destructive readout memory must re-write the contents of each memory cell as it is read otherwise the data is lost or corrupt. With Non destructive readout, NDRO, memory is able to be read multiple times between each write cycle.

primary memory consist of RAMsecondary memory consist of ROM
Intenal memory is only primary memory. The term secondary memory is used for External storage like hard disk etc.
Cache memory is smaller and quicker, primary memory larger and slower.
primary memory is built in memory on a computer it is the main type of memory.... eg RAM ROM and HDD
