mäluhaldusvigu

Mäluhaldusvigu are errors or inefficiencies that occur in the management of computer memory. These issues can significantly impact the performance and stability of software applications and the operating system itself. Common types of mäluhaldusvigu include memory leaks, buffer overflows, and dangling pointers.

A memory leak occurs when a program allocates memory but fails to deallocate it after it's no longer needed. Over time, these unreleased blocks of memory accumulate, consuming available resources and potentially leading to system slowdowns or crashes. Buffer overflows happen when a program attempts to write more data into a fixed-size memory buffer than it can hold. This excess data can overwrite adjacent memory locations, corrupting data or causing unexpected program behavior, and can sometimes be exploited for security vulnerabilities. Dangling pointers arise when a program uses a pointer to access memory that has already been freed. This can result in accessing invalid data or causing a segmentation fault, which is a critical error that typically terminates the program.

Proper memory management is crucial for developing robust and efficient software. Techniques such as garbage collection, automatic memory management, and careful manual allocation and deallocation of memory are employed to prevent mäluhaldusvigu. Developers use debugging tools and code analysis to identify and fix these errors during the software development lifecycle. Understanding and mitigating mäluhaldusvigu is a fundamental aspect of computer programming and system administration.
