Computers utilize various types of memory to store and retrieve data during different stages of operation. The primary types include RAM (Random Access Memory) and storage devices. RAM is volatile memory used for temporarily storing data that the computer's processor actively uses or processes. It allows for quick access and retrieval, contributing to the computer's overall speed and performance. There are different generations of RAM, such as DDR4 and DDR5, with each providing improvements in speed and efficiency.

Storage devices include Hard Disk Drives (HDDs) and Solid-State Drives (SSDs). HDDs use spinning disks to store data magnetically and are known for their large storage capacities at a lower cost. On the other hand, SSDs use flash memory for faster data access and retrieval, resulting in quicker boot times and application loading. SSDs are preferred for their speed and reliability, although they often come with a higher price per gigabyte.
