Question

Five programs are currently being run in a computer. Program 1 is using 10 GiB of RAM, program 2 is using 5 GiB of RAM, program 3 is using 12 GiB of RAM and program 4 is using 4 GiB of RAM. The programs are at the stage where program 5 now needs to access RAM, but RAM is presently full (RAM has a 32 GiB maximum capacity). Explain how virtual memory could be used to allow program 5 to access RAM without any of the data from the other four programs being lost.

Answer 1

Virtual memory could be used to allow program 5 to access RAM without any of the data from the other four programs being lost because it is one that tend to allows the system to give all of the process its own memory space that is said to be  isolated from the other processes.

How is virtual memory used instead of RAM?

A system is known to make use of a virtual memory and this is one that tend to make use of a section of the hard drive to act like the RAM.

With the use of virtual memory, a system can be able to load bigger or a lot of programs running at the same time, and this is one that tends to hep one to work as if it has more space, without having to buy more RAM.

Therefore, Virtual memory could be used to allow program 5 to access RAM without any of the data from the other four programs being lost because it is one that tend to allows the system to give all of the process its own memory space that is said to be  isolated from the other processes.
