Mouse

• A mouse is an input device which helps us to point at or select an item on the monitor. 
•  When we move a mouse, an arrow-like pointer moves on the monitor. 
• A mouse has the following parts:
  • left button
  • right button
  • a scroll-wheel between two buttons
  • a wire connected to the CPU

Types of Mouse

Eight types of mice are commonly used today:

• A scroll mouse features two buttons and a central scroll wheel.
  
• Two-button and three-button mice are named based on their number of buttons.
  
• A roller-ball mouse uses a ball to control cursor movement on the screen.
  
• An optical mouse employs laser light to move the cursor.
  
• A gaming mouse operates like a scroll mouse but offers faster response times.
  
• A touchpad mouse is typically integrated into laptops.
  
• A trackball mouse has a ball on top, which, when moved, controls the cursor.
  
• A touch mouse is wireless and uses a touch strip responsive to finger movements.
  

Mouse Pad

• A mouse pad is a smooth, clean mat used under the mouse.
• It helps the mouse move smoothly on the surface.
  

Holding a Mouse

• The mouse is usually held with the right hand.
• The first finger is placed on the left button.
• The second finger is placed on the right button.
• The scroll wheel is located between the two fingers.
  

Working with a Mouse

• Pressing and releasing a mouse button is called clicking, which makes a click sound.
• Left-clicking involves clicking the left button of the mouse.
  
• Right-clicking involves clicking the right button of the mouse.
  
• Single-clicking is pressing and releasing the left mouse button once to select an item.
  
• Double-clicking is pressing the left mouse button twice quickly to open a selected document.

Selecting an Item

Selecting an item highlights it on the screen.

Steps to select an item:

• Move the mouse pointer to the item and click it once to select it (the item’s color changes).
  
• Double-click the left mouse button to open the selected item.
  

Using the Right Button

• Clicking the right button once displays a set of options on the screen.
  

Dragging and Dropping a Mouse

• Dragging is moving the mouse while keeping the left button pressed to move an item on the screen.
• Dropping is releasing the mouse button after dragging to place the item in a new location.
• Steps to drag and drop an item:
  • Click the left mouse button to select an item.
    
  • Keep the left button pressed and move the mouse to drag the item.
    
  • Release the mouse button to drop the item in the new place.
    

Tech Terms

• Pointer: A small arrow on the screen that moves with the mouse.
• Dragging: Moving the mouse while holding the left button pressed.
• Dropping: Releasing the mouse button after dragging an item.
