Ideally, the microscope should be returned to its lowest-magnification objective when the user finishes his or her work. Because not all users abide by this unwritten law, it's best-practice to use the "Fine Focus" knob (the smaller diameter of the two, usually farthest from the body of the scope) when first sitting at a microscope you don't own. This will prevent the sample from breaking because you've accidentally moved the stage (the moveable, horizontal part of the microscope on which your specimen sits) too rapidly after the last use took off, leaving the objective at 40x (400x total magnification in most instances). If you verify that the objective turret is set such that the lowest magnification objective is in place, you can usually safely use the larger knob located closer to the body of the 'scope (but on the same axis as the fine knob) to bring your sample into focus. As you move to higher powers, the fine is all the adjustment you should need. COARSE, you didn't even end up answering the question previous writter! seriously!!!!! i agree with you 2nd writer!!!!
The focus knob. There's two parts to it: the coarse focus knob (the larger part) and the fine focus knob.
By the way, only use the coarse focus knob up to 10X objective. Past that (40X, 100X), ONLY USE THE FINE FOCUS KNOB unless you want to fork out a years worth of paychecks to replace the lens.
The knobs on the side of a microscope are the focus knobs. The large one is the course focus, and the smaller one is the fine focus.
It is called the coarse adjustment knob.

Nosepiece
The slide is placed on the stage.
On top of the Microscope slide, the specimen you wish to examine is place and then water and a coverslip is placed on top of that. Other things may be added depending on the speciment you wish to examine such as stainers like Iodine.
Stage
A device put onto the stage to allow precise adjustments of the slide
\to the stage
The microscope stage is the platform on which a slide is placed for viewing.
It should be placed under the clips.
A coverslip is a thin glass placed on the microscope slide.
The slide is placed on the stage.
A prepared slide for a compound light microscope is composed of a viewing sample suspended in a drop of distilled water, which has been placed on one glass slide. A second glass slide will be placed on the first slide and any residual water will be gently soaked up by a paper towel.
In compound microscopes for use for viewing thin sections at high power, specimens are mounted on a microscope slide and covered with a coverslip and are placed on the microscope stage or base plate. In stereomicroscopes the same is done however for large objects such as rocks or minerals no microscope slide is required the object to be observed is placed directly on the stage.

A pair of slide clips on the viewing stage hold down the slide.
A stage is the place where the slile for the observation is placed, and where slide can be smoothly moved with the help of some mechancal clips for viewing easy
