Mälusüsteem

Mälusüsteem refers to a computational system designed for storing and retrieving data. It is a fundamental component of any computer, enabling the processing and execution of programs. Mälusüsteem encompasses various types of memory, each with distinct characteristics regarding speed, capacity, and cost.

The primary category of mälusüsteem is volatile memory, such as Random Access Memory (RAM). RAM provides fast access to data and instructions that the processor is actively using. However, its contents are lost when the power is turned off. Another crucial part of mälusüsteem is non-volatile memory, which retains data even without power. This includes Solid State Drives (SSDs) and Hard Disk Drives (HDDs) for long-term storage, as well as Read-Only Memory (ROM) for essential firmware.

Modern mälusüsteem often employs a hierarchical structure. This hierarchy involves multiple levels of memory, with faster, smaller, and more expensive memory (like CPU caches) positioned closer to the processor, and slower, larger, and cheaper memory (like SSDs) further away. This tiered approach aims to balance performance and cost by utilizing the fastest memory for frequently accessed data and slower memory for less frequently accessed data.

The efficiency of a mälusüsteem is determined by factors such as access time, transfer rate, and capacity. System designers carefully select and configure these memory components to optimize overall computer performance for specific tasks, ranging from simple word processing to complex scientific simulations.
