Hello student, here the memory uses resident set size, rss, the amount of the physical memory used by the process, virtual memory size, the total amount of the memory used by the process including both ram and the swap space, shared memory size, the amount of the memory shared by the process with other processes and after this cpu usage, cpu usage, the percentage of the cpu time that the process is using, user time, the amount of the cpu time that the process has used in the user mode, kernel time, the amount of the cpu time that the process has used in the kernel mode and after this, the overall memory usage of all the process can be compared to the ram installed in the computer by looking at the total column in the memory usage section.

If the total value is greater than the amount of the ram installed in your computer, then some of the processes are using swap space.

Swap space is a portion of your hard drive that is used to store that is not currently being used by the processes.

If the overall memory usage is high, so you may need to close some of the processes that are using a lot of memory...
