A computer mouse is a handheld device that can control the cursor on your laptop, MacBook, iMac or desktop PC. It allows you to use the cursor to perform tasks like selecting, clicking, dragging and dropping items. Standard computer mice are designed with two buttons, left for selection and right for context menus. They also have a scroll wheel for navigating your computer screen. Some computer mice have more advanced designs with extra programmable buttons that are popular with gamers and people who do a lot of multitasking. Computer mice come in both wired and wireless models for convenience. For wireless mice, make sure you have the right batteries in case they need to be replaced.

The best computer mouse is one that offers the most ergonomic support for your hand. This way, you can stay comfortable all day and don’t have to worry about your hand being tired. There are different types of mouse designs to consider including palm, claw or fingertip models. You should also consider the weight of the mouse you’re looking at. Lighter mice are more agile while heavier mice are more stable. Also think about whether you want a wired mouse for a direct connection to your computer or a wireless mouse that offers more movement. If you play a lot of video games or want to improve your productivity, consider a mouse that has extra programmable buttons. Keep your mouse and other devices clean with the right electronic cleaning supplies like dusters and cleaning wipes.

There are three main types of computer mice: optical, laser and wireless mice. This is based on the technology they use and how they connect to your computer. Optical mice use an LED light and sensor to track cursor movement. They’re good for office work and gaming on non-glossy surfaces. Laser mice use laser technology for higher sensitivity and more precise movement. They can be used on glossy or glass surfaces. Wireless and Bluetooth mice connect to your computer without a cord for more freedom of movement. They either connect using a USB receiver or Bluetooth connectivity. If you use a laptop, make sure you have a padded laptop bag to protect your laptop, mouse and other accessories.

There are subtle differences between a Bluetooth mouse and a USB wireless mouse. Bluetooth mice let you free up a USB port because they connect with Bluetooth instead of a dongle. Bluetooth mice also allow you to connect to tablets as well as desktops and laptops. USB wireless mice offer a more stable connection with their USB dongle and deliver more responsive movements. They are also easier to set up by simply plugging in the USB dongle and turning the mouse on.
