Memory Allocation Now we will discuss about the various memory allocation schemes. Single Partition Allocation In this scheme Operating system is residing in low memory and user processes are executing in higher memory. Advantages * It is simple. * It is easy to understand and use. Disadvantages * It leads to poor utilization of processor and memory. * Users job is limited to the size of available memory. Multiple-partition Allocation One of the simplest methods
