• Performance Monitor: The Performance Monitor is a embedded feature in windows that allows the user to view and collect data on how their system is functioning through data such as counters.

• Interrupt Requests: An interrupt request is when an I/O device alerts the system that it has an input for the system.

• I/O port: An I/O port is a slot on a device where an I/O device is plugged in so that it can communicate with the system.

• Use of counters: A counter is used to track the status and data of system properties

• Data Collector Set: A data collector set is a function of the performance monitor that gathers and organizes data from resources such as counters into a single place. This is useful for viewing data on large systems or for when you want to look at a particular aspect of a system over time without having to continually dig around.
