#AVAILABLE PHYSICAL MEMORY LOWER THAN TOTAL FREE#

In other words, it is a memory management technique performed by the operating system. When executing these programs, they are called processes.

Likewise, the free memory can be allocated to a new program. After completing the execution, the programs go back to the hard disk. It takes less time to access data from the physical memory than accessing the data from the hard disk. Therefore, those programs are first placed in the physical memory so that the CPU can execute them faster. It requires more time for the CPU to access the hard disk always to execute programs. Usually, the hard disk stores the programs. It holds programs on the execution lineup. The CPU can directly access the physical memory. In other words, the memory addresses increases in a linear manner. Also, this memory is linearly addressable. However, power failures and interruptions can erase the data in the physical memory. Therefore, it requires a continuous flow of power to retain data. Physical memory refers to the RAM or the primary memory in the computer. Main Memory, Physical Memory, RAM, Virtual Memory вЂ“ Comparison of Key Differences Key Terms What is the Difference Between Physical and Virtual Memory On the other hand, virtual memory extends the capacity of the main memory to execute large programs using the hard disk. Physical memory is the primary memory that has the currently executing programs. Moreover, this process keeps on track of every memory location in order to allocate processes and to free the memory. It allows the processes to move back and forth between the main memory and hard disk during the time of executing the program. Memory management is an important operation in an operating system. The main difference between physical and virtual memory is that the physical memory refers to the actual RAM of the system attached to the motherboard, but the virtual memory is a memory management technique that allows the users to execute programs larger than the actual physical memory.
