Memory Functions in Operating Systems

Memory Management is a very important part of the operating system. If you want to execute any function, this functionality will be achieved by accessing the computer's memory. When you think of memory management, think of purchasing an airport ticket.  This purchase can happen months in advance and all the data is collected for your flight, stored, and executed on the day of travel. "Memory allocation. One of the simplest methods for allocating memory is to divide memory into several fixed-sized partitions. Each partition may contain exactly one process. Thus, the degree of multiprogramming is bound by the number of partitions"(Patterson & Hennessy 2014). Virtual memory can use secondary memory as if it was main memory. Virtual can use both hardware and software to function.  Main memory or computer memory (RAM) stores the information in hardware.
