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.
To make fine adjustments on a microscope, use the fine focus knob to sharpen the image. This knob allows you to bring the specimen into clear focus by moving the objective lens slightly up or down. Use it after using the coarse focus knob to roughly focus the image. Make small, careful movements until the specimen is sharply in focus.
The small intestine is connected to one side of the stomach, and on the other end, it is connected to the large intestine. The small intestine is responsible for further digestion and absorption of nutrients from food before passing the remaining waste to the large intestine for processing.
A comparison microscope is commonly used to see fingerprints. This type of microscope allows two objects (such as two fingerprint samples) to be viewed side by side, making it easier to analyze their similarities and differences.
The fine adjustment, the two little knobs on both sides of a compound microscope, is rotated to move the body tube down or the stage up in tiny distances to help you focus in HIGH power.The fine focus knob is geared with a different ratio than the coarse knob to "fine tune" your focus. It allows for tiny adjustments to the focus setting, rather than larger ones.
There're two knobs at the side of a light microscope (this is just my experience, it may be different if you're using different brands of microscope or even an electron type microscope). For first focus, adjust the larger knob (also known as rough adjustment) followed by the final focus (to sharpen the image), by adjusting the smaller knob (known as fine adjustment).
The stage on a microscope is typically moved using coarse and fine adjustment knobs located on the mechanical stage assembly. These knobs allow the user to move the stage up and down or side to side to adjust the position of the specimen for viewing.

There are two adjustment knobs (coarse and fine) on a microscope so you can move the stage at two different speeds. The coarse moves a lot per revolution, while the fine adjustment knob moves the stage at such small increments that it is nearly impossible to notice when looking from the side. The coarse adjustment knob should be used to get the stage closer to the lens only while you are looking at the microscope from the side. The fine adjustment knob can be used when you are looking into the microscope because there is a much lower chance of running the stage into the lens and breaking it.

A microscope should be held with two hands, one on each side of the base to ensure proper stability and balance. Keep your fingers away from the lenses and focus knobs to avoid damaging the delicate components. Adjust the position of the microscope on the table to ensure a comfortable viewing angle.
You use the fine adjustment to focus in HIGH power with a compound microscpe.

A stereo microscope shows two slides side by side at the same time and is used for comparison. A compound microscope only shows one slide.
Both of the small posts (pos & neg) are primaries. The large connection is the secondary.
