The term monitor is often used synonymously with computer screen or display. The monitor displays the computers user interface and open programs, allowing the user to interact with the computer, typically using the keyboard and mouse.
Older computer monitors were built using cathode ray tubes (CRTs), which made them rather heavy and caused them to take up a lot of desk space. Most modern monitors are built using LCD technology and are commonly referred to as flat screen displays. These thin monitors take up much less space than the older CRT displays. This means people with LCD monitors have more desk space to clutter up with stacks of papers, pens, and other objects.
Monitor can also be used as a verb. A network administrator may monitor network traffic, which means he watches the traffic to make sure the bandwidth usage is within a certain limit and checks to see what external sources may be attempting to access the network. Software programs may monitor the systems CPU performance as well as RAM and hard disk usage.
Finally, monitors also refer to speakers used for monitoring sound. Audio engineers typically use studio monitors to listen to recordings. These high-end speakers allow the engineers to accurately mix and master audio tracks. So a sound mixer could be monitoring a recording visually using a computer monitor, while monitoring the sound using audio monitors at the same. As you can tell, monitor serves as a rather multipurpose word.

In sound [parlance], any device that allows a performer to hear themselves. Also applies to most all forms of non [end user] [playback].
On stage, the monitors are usually wedge shaped speakers that point toward the performers. They are mixed to provide the sound that is not present on stage, usually vocals, keyboards, and other non [amped] instruments, although they often [reinforce] such instruments.
Larger concerts will have a [monitor] mixer and engineer that is off to the side of the stage with a special multiple bus console which is fed via a stage [splitter]. Smaller concerts use the auxiliary buses on the main console.
In studio, the monitors are both for performer and producer, the latter often using speakers called studio monitors and the former commonly using headphones. These allow both parties to hear the mix and, most importantly, allow the performer to hear themselves. The studio monitor speakers are used to mix down the performance, and to monitor the performer.
Common types are Stage Monitors, Studio Monitors, In-Ear Monitors, and Isolation Headphones.
