Apr 21, 2023 · Secondary memory is a type of computer memory that is used to store data and programs that can be accessed or retrieved even after the computer is turned off. Unlike primary memory, which is volatile and temporary, secondary memory is non-volatile and can store data and programs for extended periods of time.
Moreover, it is the most important component of a computer system as it cannot perform even simple tasks without it. Basically, the computer memory is of two types namely, primary memory (Random Access Memory (RAM) and Read Only Memory (ROM)) and secondary memory (CD, DVD, hard disk, etc).
Apr 14, 2023 · Secondary memory is a type of computer memory that is used for long-term storage of data and programs. It is also known as auxiliary memory or external memory, and is distinct from primary memory, which is used for short-term storage of data and instructions that are currently being processed by the CPU.
Feb 22, 2017 · Secondary memory is computer memory that is non-volatile and persistent in nature and is not directly accessed by a computer/processor. It allows a user to store data that may be instantly and easily retrieved, transported and used by applications and services.
Mar 13, 2024 · What is Secondary Memory. Definition -: Secondary memory is the secondary storage device of the computer which is used to store the program in the computer and the output obtained from the execution of the program permanently.
If we need to store large amount of data or programs permanently, we need a cheaper and permanent memory. Such memory is called secondary memory. Here we will discuss secondary memory devices that can be used to store large amount of data, audio, video and multimedia files.
The secondary memory is accessed indirectly via input/output operations. This memory is also called permanent, external, stable or persistent memory. It is characterized by its slowness and cheapness, relative to the RAM, and by its permanent appearance. The CPU does not directly process it.
When computers need to store data for long-term retrieval, they use secondary memory, also known as auxiliary storage or external memory.
What is Secondary Memory - In this chapter of computer basic tutorial, we will learn about what is secondary memory in computer, example of secondary memory in computer, auxillary memory, access method in secondary memory like Sequential, Direct, Random, Associative access.
Secondary Memory. As we know that the primary memory is volatile therefore, we need some devices to store the data permanently so we use some external storage devices for this purpose which we name as the secondary memory. Let us study secondary memory in more detail in the following chapter. Fixed and Removable Storage. Share with friends.
