Description: Memory resizing is the process of changing the size of memory blocks allocated during the runtime of a program. This mechanism is fundamental in memory management of computer systems, as it allows applications to dynamically adapt to changing resource needs. Through techniques such as dynamic memory allocation, systems can increase or decrease the amount of memory assigned to a process based on its demand. This is especially useful in environments where resources are limited or where multiple applications compete for the same memory. Memory resizing is performed through specific functions that allow programs to request more memory or release what they no longer need, thus optimizing the use of available resources. Additionally, this process helps prevent issues such as memory fragmentation, ensuring that memory blocks are used efficiently and that applications run smoothly. In summary, memory resizing is a key feature that enables systems to effectively manage memory, ensuring optimal performance and a seamless user experience.
