A system monitor can be a software program or hardware device that tracks various aspects of a computer system, such as running programs, resource usage, and hardware details. Software monitors are more common and can run in the background, while hardware monitors display information on a digital screen. The collected information can help improve computer performance by terminating unnecessary programs and monitoring internal temperatures and peripheral behavior.
A system monitor is a program or piece of hardware that monitors various aspects of a computer system and then displays information regarding the state of that system. This type of monitor typically takes the form of a software program that comes with an operating system (OS) or used as a standalone program. Hardware system monitors are also available, although these are fairly specialized devices and not as frequently used as software monitors. A system monitor typically keeps track of various aspects of a computer system, including what programs are running, how resources are being used, and some details about the hardware installed on a computer.
There are two main types of system monitors typically used to track the functions of a computer system: software or hardware monitors. A software monitor is a program, or utility within another program, that allows a computer user to monitor ongoing processes within a computer system. This type of program often uses little resources on its own and can run in the background during other operations. A hardware system monitor is a physical device that connects to a computer system, either internally or via a universal serial bus (USB) port, that monitors various aspects of the computer system and displays the information on a small digital screen.
Regardless of the type of system monitor you use, the information it collects typically relates to computer software processes and memory, or the condition of the hardware inside a computer. When software and processes within a computer are monitored, the information collected typically pertains to how resources, such as memory, are being used and what programs are currently running on a system. This can allow a computer user to terminate programs that may be running in the background on a computer system, which can free up memory and improve computer performance.
Hardware monitored through a system monitor typically broadcasts information about the internal temperatures of devices in a computer and the behavior of peripherals. A number of different systems are used in a computer to control the heat generated within the computer, including heat sinks and fans, and a system monitor can allow a computer user to see how these systems work. The monitor can typically broadcast the speeds at which the internal fans are spinning, as well as the temperatures for the central processing unit (CPU), power supply, and graphics card. A hardware monitor can also broadcast information about devices or peripherals that are unresponsive or malfunctioning.
