Computer memory refers to the physical devices within a computer system that store data temporarily or permanently. It is an essential component of electronic devices such as computers, desktops, and other digital systems, facilitating the execution of various tasks and operations. Computer memory exists in different forms and capacities, including RAM (Random Access Memory) and ROM (Read-Only Memory), which are responsible for storing data that can be accessed randomly or only read, respectively. RAM is a type of volatile memory that temporarily stores data and instructions required by the CPU to perform tasks. It is faster than other types of memory but loses its contents when the system shuts down. ROM, on the other hand, is a non-volatile memory that stores firmware or software that cannot be modified or altered. Computer memory plays a critical role in ensuring the efficiency and speed of computer systems. It enables users to run multiple applications simultaneously, store large files, and perform complex calculations with ease. As technology advances, computer memory continues to evolve, offering higher capacities, faster speeds, and improved performance.
