प्राइमरी और सेकेंडरी मेमोरी में क्या अंतर है • What is the difference between primary and secondary memory
In the world of computers, memory refers to the space where data and instructions are stored for processing. There are two types of memory in a computer: primary memory (also known as main memory) and secondary memory (also known as auxiliary memory). Primary Memory: Primary memory is the main memory of a computer, which is directly accessible to the processor. It is also called the volatile memory because it loses its contents when the computer is turned off. Primary memory is used to store data that is currently being used by the CPU, including the operating system, programs, and data that the CPU is actively processing. There are two main types of primary memory: Random Access Memory (RAM) and Read-Only Memory (ROM). RAM is a type of primary memory that can be read and written to by the CPU. It is used to store the data and programs that are currently being used by the computer. When the computer is turned off, the contents of RAM are lost. This is why RAM is also called volati...
