Memóriakezelésbe

Memóriakezelésbe refers to the process of managing computer memory. This involves allocating memory to programs when they need it and reclaiming it when they are finished, ensuring that multiple programs can run concurrently without interfering with each other. Operating systems are primarily responsible for implementing memory management.

There are several common techniques used in memory management. One is paging, where memory is divided into fixed-size blocks called pages. Another is segmentation, which divides memory into variable-size blocks called segments, often corresponding to logical program units like code, data, or stack. Virtual memory is a technique that allows a computer to compensate for a lack of physical memory by temporarily transferring data from random access memory (RAM) to disk storage. This creates the illusion of having more RAM than is physically available.

Effective memory management is crucial for system performance and stability. Poor memory management can lead to slowdowns, crashes, and security vulnerabilities. Techniques like garbage collection, used in languages like Java and Python, automatically reclaim memory that is no longer in use by a program, reducing the burden on the developer. The efficiency of memory management directly impacts how many applications can run simultaneously and how quickly they can execute.
