Trackball to my understanding is the ball under the manual Mice which is use to move the pointer.
Most modern computer mice do not have a ball, instead they use optical sensors.
A good "mouser" cat would handle the mice. If you have no pets or small children, you can use poison. Otherwise, you need a mouse trap.
TRAPS
yes you can but its just that the ball want come smoothly of the bat
mice
Turbochargers turn too fast for ball bearings. Sleeve bearings are typically used in this application.
you loose your turn and your opponent gets to use the q ball to his adventage
The principal parts of a mechanical mouse are left and right buttons, rotating ball and scroll button. Instead of a rotating ball, optical mice use light to move the cursor.
It has to be assumed that you are referring to purchase of a cue ball. There are no choices for cue ball size for normal play. The larger cue ball is intended only for use on coin operated tables.
The laser of the optical mouse may bounce off certain colors and shapes on a mouse pad. * There are no disadvantages to a optical mouse. The optical mouse just works better and smoother than the ball mouse, and you never have to worry about the ball getting dirty or hanging. I would suggest getting an optical mouse and throwing the ball mouse away. For this you definitly need the opinion of someone who has to sufffer the ball mouse at least once a week. ie: School pupils. I have two IT lessons a fortnight, and at our school you have a choice between overly chunky optical mice or cheap, way too light ball mice. I end up tolerating the ball mice as I am very picky about my mice. I, personally like mice with a bit of weight on them, but the thick plastic outer of the school's optical mice is ridiculous. Generally, schools don't provide pupils with mousemats on the theory that they will be nicked/tooexpensive, so the only way to get the ball mice to operate in a friendly manner is to clean it before use, or use your science book as a substitute mousemat. The moral of this long-winded story is:
If you have a problem with mice in your home or office, there are several ways to get rid of them and prevent further invasions. To keep mice from getting in, make sure there are no holes in your floors or walls that mice can use to get inside. Also keep food products, such as animal foods, crackers, flour, etc put away in sealed containers where mice can't get to them, as they will often go inside to find food. If you use traps, make sure you keep any rat poison away from the reach of kids and pets.
