Monitors are a synchronization mechanism based in some sense on data abstraction A monitor encapsulates the representation of a shared resource and provides operations that are the only way of manipulating it In other words, a monitor contains variables that represent the state of the resource and procedures that implement operations on the resource; a process or thread can access the monitor's variables only by calling one of its procedures Mutual exclusion among the procedures of a monitor is guaranteed; execution of different procedures, or two calls to the same procedure, cannot overlap Conditional synchronization is provided by condition variables (see condition variables) A good reference is [Andrews91]

A computer's display screen The characteristics of the monitor must match those of the video driver circuitry Thus, a high-resolution graphics board requires a high-resolution monitor Modern monitors are all VGA or better
The part of a computer that contains the screen where messages to and from the central processing unit (CPU) are displayed Monitors come in a variety of sizes and resolutions The higher the number of pixels a screen is capable of displaying, the better the resolution Sometimes may be referred to as a CRT

You can refer to a person who checks that something is done correctly, or that it is fair, as a monitor. Government monitors will continue to accompany reporters. Ironclad warship originally designed for use in shallow harbours and rivers to blockade the Confederate states in the American Civil War. The original ironclad, built by John Ericsson, was named Monitor Its innovative design included minimal exposure above the waterline, a heavily armoured deck and hull, and a revolving gun turret. The inconclusive Battle of the Monitor and Merrimack (1862) was the first between ironclad warships. Never seaworthy, the Monitor sank during a gale off Cape Hatteras that same year, but the U.S. Navy built many improved monitors during the war. The British navy kept its monitors in service as late as World War II. Christian Science Monitor The Monitor and Merrimack Battle of the monitor lizard
