Secondary Memory originates from secondary storage devices are the ones that have all the applications and data from these programs and other files stored on the system on either a hard disk or other objects such as optical disk. One of the most common forms of this memory is the hard drive of a computer, which is used to store the operating system (OS) and other programs. सेकेंडरी मेमोरी क्या हैं? Unlike primary memory, secondary memory is not accessed directly by the CPU. Level 2 or Cache memory – It is the fastest memory which has faster access time where data is temporarily stored for faster access. CPU directly does not access these memories instead they are accessed via input-output routines. The hard disk is used for long-term storage of programs and data. Secondary memory is also called non-volatile memory because data are stored permanently even after the shut down of the computer or any other machine. Secondary memory is an auxiliary memory of the computer. It is small in size and once power is off data no longer stays in this memory. Secondary Memory – Secondary Memory is that memory in which data are stored permanently even after the shut down of the computer or any other machine. Primary memory is the main memory of the computer which can be directly accessed by the central processing unit, whereas secondary memory refers to the external storage device which can be used to store data or information permanently. So, when the computer starts then all data of OS, first loaded into Random Access Memory(RAM). See more. – Definition. Secondary memory is cheaper than primary memory but is also slower in both reading and writing. It may also refer to removable storage media, such as USB flash drives, CDs, and DVDs. Secondary Memory. Define secondary memory. Secondary memory is also known as secondary storage. Secondary storage is non-volatile and has lower cost per bit stored but it generally has an operating speed far slower than that of primary storage. Secondary storage data usually resides on devices with non-volatile memory (NVM), such as hard disk drives , solid-state drives , tape drives, optical media and cloud storage.
