Computer Mouse

The mouse woks by, the rays of the mice send messages to the computer and that will allow the cursor to move around in the computer

A trackball is a pointing input device just like a mouse. It just gets the input from the user in a slightly different manner. Instead of moving the mouse around on a desk, the user just rolls the ball in the corresponding direction.

This is advantageous in situations where there may not be enough room for a proper mouse, and is sometimes claimed to be more comfortable for carpal-tunnel sufferers.

Go to a computer accessories shop and look for the green USB to PS2 Mouse adapter. Or you can buy it online.

See the picture at this link (check that the port matches your PC mouse port):

IMPROVED:

Please note the answer above is for converting a USB to PS2 connector, NOT USB to Serial Port.

A USB to Serial Port adapter does not, to my knowledge, exist. So please verify if you want a PS/2 (small, round connector) or Serial Port (long, flat connection with many pins)

Also, the color of the adapter may vary.

Actually keyboards of various kinds are the most commonly used input devices for entering data.

Mice, roller balls, trackpads, etc. are used for making menu selections, etc.

Optical Mouse
All mice have moving parts. There is no such thing as a computer mouse not having moving parts. And before you pop off (or mouth off or whatever you want to call it), the "buttons" that you use to "click" an icon or link and the scroll wheel of the mouse are moving parts. As a matter of fact, the entire mouse is a moving part. Unless it is a trackball mouse, in which case only the trackball and the buttons are the only moving parts.

The right mouse button it bring up tool box with options in it also highlight words

They are disc drives which read Compact Discs (CDs). They are versatile and transportable and can be used to perform various tasks such as reading data from the computer and listening to audio.

well my good ol friend computer mouses are important for moving the pointer on the monitor and B.I.T.C.H

First try to move the mouse all the way to the top left corner, as you might just not be noticing it where it is. If it won't move to the top left corner then make sure the mouse itself is powered and working as damage to the cord is not always obvious visually.

It is called "drag and drop"

Invented by Apple Computers

For computers, the main output devices are the monitor, speakers and printer (or multi-function device, like printer/scanner/copier). You could also consider an external drive (hard drive, CD/DVD burner, flashdrive or thumbdrive) to be a sort of output device, although that's using the term very loosely, because they are really data storage media.

Generally when you perform this action, it will move the file from its location to the new one, unless you do this across drives. In that case, you will have dragged a copy of the file to the new drive and the original one will still be in its original place. When you are dragging a file, keep a sharp eye on your mouse cursor while your finger is still holding the left button. If you see an arrow on the file, it means it is about to make a shortcut to the file, but it will still remain at its original location. If it's a plus symbol, it is about to make a copy of it. If you see nothing else, it is about to move the file completely.

To completely remove and place a file to another drive, highlight the file, press CTRL+X to cut it from its location (you won't lose it unless a paste action is performed), then go to the other drive, open the folder where you want it to go and press CTRL+V to paste it. If it is a large file, it is safer to press CTRL+C to copy the file instead of cutting it in case it suffers an error in transit and you may lose both. When the copy is successful, you can delete the original.

Advantages:

- Less moving parts = less likely to break

- Easier to maintain, does not require cleaning

- Higher sensitivity

- Works on a wider variety of surfaces

Disadvantages:

- May have problems on glossy surfaces such as glass

- Higher sensitivity

- Many optical mouses have lights in them, which some people find annoying.

The left button, which is the primary button as default to many mouse settings, is to command the basic way of communicating with the computer to act.

It may have various functions defined for it. Particularly for the left-handed.

This is because the mouse icon on screen is often an arrow, and in computer jargon the user "points" at a part of the screen.

Pointing is done by moving the mouse until the tip of the arrow on screen is at the desired place, such as a menu title.

Input devices.

The most common type of computer with an integrated monitor and keyboard would be the laptop. However, with the advent and popularity of various mobile computing devices, you may want to add various tablets and smartphones to the list as well.

In the future, we may have even more integrated computers where the monitor functions as the keyboard through touchscreen applications.

When you move a mechanical (computer) mouse, the roller ball transfers its movement to two slotted encoder wheels that have two sensors that detect the position of the wheels. The sensors are mounted an odd half number of teeth apart, giving two pairs of pulse trains that are 90 degrees out of phase with respect to each other. Running these pulse trains through logic comprising some XOR gates and a flip-flip, you can drive an up/down counter in such a way that the count represents the horizontal or vertical position of the roller. At the point where a change is detected, either by a movement of the roller or a change in status of a button, a message is sent to the computer that includes the button status and the delta-x and delta-y of the roller since the last update. The computer driver then integrates that into mouse messages that drive (typically) windows.

For a laptop computer,all of the physical hardware is usually combined.

In a desktop, you normally have a tower containing the motherboard, hard drive, CD/DVD drives, and various ports and input connections. The peripherals are the display (monitor, CRT or LCD), the keyboard, the mouse, speakers, a printer, and any external drives.

The major disadvantage of a ball mouse is that it is not as easy to use as other types of mice like optical and laser. It is also comparatively much less durable.

The mouse is called the mouse because before it was wireless they were all corded and the cord was supposed to be the tail which makes it look a little bit like a mouse or a rat but rat would sound disgusting hence the name mouse
