What is the resource management in OS?

Resource management is the dynamic allocation and de-allocation by an operating system of processor cores, memory pages, and various types of bandwidth to computations that compete for those resources. The objective is to allocate resources so as to optimize responsiveness subject to the finite resources available.

Does the OS allocate memory?

From a program's heap the OS allocates memory for dynamic use. Given a pointer to any one of the allocated blocks the OS can search in either direction to locate a block big enough to fill a dynamic memory allocation request.
