Memory management

“

- [Instructor] Memory is a critical computing resource, vital for ensuring both the kernel and the user applications run smoothly. That's why understanding how an OS manages memory is so important. In a computing device, memory refers to the hardware used for storing and retrieving information. Broadly, there are two types of memory. Volatile memory, such as RAM, serves as the main memory and is used to temporarily store data at a high speed while the system is powered on. Non-volatile memory, like flash storage, retains data permanently, even when the device is powered off. To store the data efficiently, memory is typically divided into sectors and blocks with data organized in units such as bytes. However, managing these memory blocks is a complex task, and it's usually handled by the memory allocation algorithm provided by the operating system. At runtime, a memory is logically organized into different regions, such as a stack, heap, data, and code segments. The stack and the data…
