Memóriarendszerek refer to the ways in which information is stored, organized, and retrieved within a computer system. These systems are fundamental to computing, enabling devices to perform calculations, run applications, and store data. At a high level, computer memory is typically divided into two main categories: primary memory and secondary memory.

Primary memory, also known as main memory or RAM (Random Access Memory), is volatile and fast. It holds the data and instructions that the CPU (Central Processing Unit) is actively using. Because it is volatile, the data stored in RAM is lost when the power is turned off. RAM is crucial for the immediate performance of a computer, allowing for quick access to frequently used information.

Secondary memory, on the other hand, is non-volatile and slower than primary memory. It is used for long-term storage of data and programs. Examples of secondary memory include hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, and optical discs. Data stored in secondary memory persists even when the power is off, making it suitable for archiving files and installing software.

Beyond this broad classification, there are various architectural considerations and technologies within memory systems. Cache memory, for instance, is a small, very fast type of primary memory that stores frequently accessed data from RAM, further accelerating CPU operations. The way memory is addressed and managed by the operating system also plays a critical role in how efficiently the system utilizes its available memory resources. The continuous evolution of memóriarendszerek aims to increase speed, capacity, and energy efficiency.
