The Processes tab shows its information in columns. To help you differentiate between data values (that is, for data points that are low, medium, or high), Windows 8 uses a “heat map” paradigm. This type of display lets you look across columns and rows and data that represent different types of data (CPU, memory, disk, and network usages) and get a quick view of the data and see any hot spots in the values. For example, if memory usage for a process or application is high compared to other running processes or applications, the heat map shows a brighter orange color. Lower values are in lighter shades, such as light tan or light yellow. Microsoft designed these heat maps to allow users to visualize and digest the information quickly.
You can sort items by clicking any column heading. For example, you can click the Memory ...
