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.
These devices store a large amount of data like audios, videos, text files, images, etc. It refers to the different storage devices which we can use to store data. Hence, we can also call these devices external memory. Moreover, it is of two types namely, fixed and removable.
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.
Apr 14, 2023 · Secondary memory is also termed external memory and refers to the various storage media on which a computer can store data and programs. The Secondary storage media can be fixed or removable. Fixed Storage media is an internal storage medium like a hard disk that is fixed inside the computer.
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.
Secondary Memory. The secondary storage devices which are built into the computer or connected to the computer are known as a secondary memory of the computer. It is also known as external memory or auxiliary storage. The secondary memory is accessed indirectly via input/output operations.
Mar 8, 2024 · The memory devices used for primary memory are semiconductor memories. The secondary memory devices are magnetic and optical memories. It can hold data/information currently being used by the processing unit. It can hold data/information that are not currently being used by the processing unit.
When computers need to store data for long-term retrieval, they use secondary memory, also known as auxiliary storage or external memory. Storage types. Personal computers come with a hard drive, a permanently attached secondary storage. Many computers have input ports for USB drives or SD cards, forms of portable secondary storage.
Secondary memory serves as an external memory devices that is used to hold large amount of data permanenty. Since secondary memory are external devices so the cpu cannot directly access it. Secondary memory is also known as auxillary 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.
