|| There are two types of memories: Primary and
Secondary. The primary memory or the main memory is part of the main computer system.
The processor or the cpu directly stores and retrieves information from it. This memory is accessed by CPU, in random fashion. That means any location of this memory can be accessed by
the CPU to either read information from it, or store information in it. The primary memory itself is
implemented by two types of memory technologies. The first is called random access memory(RAM) and the other is read only memory(ROM). A more
appropriate name for RAM is RWM(read write memory), the CPU can write and read information from any primary memory location implemented using RAM. The other
part of primary memory is implemented using ROM which stands for Read Only
