Disk Memory

Disk memory is a type of computer memory that stores data on a permanent basis. It is also known as secondary memory or external memory, and is used to store data that needs to be retained even when the computer is turned off.

• Disk memory can be divided into two types: hard disk drives (HDD) and solid state drives (SSD).
• HDDs use magnetic disks to store data, while SSDs use flash memory.
• HDDs are generally cheaper and have larger storage capacities, while SSDs are faster and more reliable.
• Both types of disk memory can be used to store operating systems, applications, documents, media files, and other types of data.
