Computer joysticks

A computer joysticks is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick.The joystick has been the principal flight control in the cockpit of many aircraft, particularly military fast jets, where centre stick or side-stick location may be employed. Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles and zero turning radius lawn mowers. Miniature finger-operated joysticks have been adopted as input devices for smaller electronic equipment such as mobile phones. Most joysticks are two-dimensional, having two axes of movement (similar to a mouse), but one and three-dimensional joysticks do exist. A joystick is generally configured so that moving the stick left or right signals movement along the X axis, and moving it forward (up) or back (down) signals movement along the Y axis. In joysticks that are configured for three-dimensional movement, twisting the stick left (counter-clockwise) or right (clockwise) signals movement along the Z axis. These three axes - X Y and Z - are, in relation to an aircraft, roll, pitch, and yaw.

viruses create chaos

If you have a virus checker, when was the last time you updated it? You’d be surprised at how many people say, “Huh?” You can update these for free and should at least once a week. Newer versions even do it for you. Be wary of opening e-mails with attachments, even from those you know. Scan every one with your virus software first. Keep backups of your hard drive that are three or four days old and constantly rotate them so you will have a virus-free version at all times. Viruses seem to love to attack on Monday, though there is no real pattern. Always update your virus program on Monday, at the very least.
