There are two type of  Internal  Memories 

1. RAM 
2. ROM 
___________________________________________________________

RAM memory - 

@ wired-in addressing logic – are used to access individual words

@ rapid reading & writing is possible

@ volatile – constant power supply required

@ temporary storage

ROM Memory - 
@ data is permanently in main memory, i.e., read-only 

@ program permanently in main memory 

@ nonvolatile 

@ no power source required 

@ information is “burned”, i.e., “hard-wired” into chip during fabrication

@ chip creation must be exact – an error in a single bit invalidates the entire chip run 

@ high-volume production runs

Answer 2

The two types of internal memory in the computer system is Primary Memory and Secondary Memory.

1. Primary Memory - This term is used to refer to the Random Access Memory (RAM) which is a high speed memory with high random access speeds. All the necessary things required for the smooth running of the system are stored in it temporarily. Its only drawback is that it's a volatile memory i.e., when the power is turned off, everything stored in it is wiped out.

  2. Secondary Memory - This term is used to refer to the Hard Disk Drives (HDD) which are used to store a large amount of data for a longer time. It stores the data permanently. Although it has much slower access speed in comparison to RAM, it does have its own perks i.e., It is non-volatile and very cheap.
