Secondary Storage
Secondary storage is an additional memory system located outside of the main memory. It serves as a long-term memory (LTM) for the computer, where data is stored for extended periods. This type of storage is used to cache frequently accessed data, improving the speed and performance of the system.
Secondary storage can be divided into two main types: hard disk drives (HDDs) and solid-state drives (SSDs). HDDs are traditional hard drives with spinning disks that rotate beneath a magnetic head. SSDs are newer type of storage that uses flash memory chips to store data.
Secondary storage provides several important functions:
Cache data: It stores frequently accessed data from the main memory, reducing the time taken to access it.
Extend memory capacity: It expands the available memory of the computer, allowing it to handle larger projects or store more files.
Improve performance: By storing frequently accessed data closer to the processor, secondary storage speeds up system operations.
Examples:
A hard disk drive (HDD) is a common example of secondary storage.
A solid-state drive (SSD) is a newer type of storage that is faster and more reliable than HDDs.
A computer with a large hard disk drive may have secondary storage connected to it to provide additional storage space
