Every computer has both primary and secondary storage, with primary storage acting as a computer's short-term memory, and secondary as a computer's long-term memory.

What type of storage is ROM?

Read-only memory (ROM) is a type of storage medium that permanently stores data on personal computers (PCs) and other electronic devices. It contains the programming needed to start a PC, which is essential for boot-up; it performs major input/output tasks and holds programs or software instructions.

What is difference between disk and memory?

ARCHIVED: What is the difference between memory and disk storage? The term "memory" usually means RAM (Random Access Memory); RAM is hardware that allows the computer to efficiently perform more than one task at a time (i.e., multi-task). The terms "disk space" and "storage" usually refer to hard drive storage.

What are primary storage devices?

Primary storage is a key component of a computer system that enables it to function. Primary storage includes random access memory (RAM), read only memory (ROM), cache and flash memory. Each of these have different uses within the computer.
