Task Manager

• MEM Usage—This bar graph shows the amount of virtual memory your computer is using.

• Memory Usage History—This line graph tracks the size of your virtual memory over time. It only displays the results; it doesn't actually record them anywhere.

• Physical Memory Total—This number represents the total amount of RAM installed on your computer.

• Physical Memory Available—This number shows the amount of RAM available for CPU processes. This number will never go to zero because the operating system will swap data to the hard disk as the memory fills.

• Physical Memory System Cache—This is the amount of RAM being used by the file cache.

• Commit Charge Total—This number shows the size of virtual memory in use. You'll notice that this number matches the number shown in MEM Usage.

• Commit Charge Limit—This shows the size of your paging limit. The paging limit is the maximum size your virtual memory can be without making changes to its configuration.

• Commit Charge Peak—This number shows the highest amount of virtual memory used since you began tracking usage.

• Kernel Memory Total—This number shows the amount of paged and nonpaged memory used by the operating system's kernel. The kernel is the central core of the operating system that does most of the background work.

• Kernel Memory Paged—This number shows the amount of virtual memory set aside for the kernel.

• Kernel Memory Nonpaged—This is the amount of RAM dedicated to the operating system's kernel.

• CPU Time—The total processor time, in seconds, used by the process since it was started.

• CPU Usage—The percentage of time the threads of the process used the processor since the last update.

• Memory Usage—The amount of main memory, in kilobytes, used by the process.
