Computer Basics

Peripherals you can use with your computer

The most basic computer setup usually includes the computer case, monitor, keyboard, and mouse, but you can plug many different types of devices into the extra ports on your computer. These devices are called peripherals. Below are a few examples of peripherals.

A printer

• Printers: A printer is used to print documents, photos, or anything else that appears on your screen. There are many types of printers available, including inkjet, laser, and photo printers. You can also buy an all-in-one printer, scanner, and copier.
• Scanners: A scanner allows you to copy an image or document and save it to your computer as a digital (computer-readable) image. Many scanners are included as part of an all-in-one printer, scanner, and copier, although you can also buy a separate flatbed or handheld scanner.
• Speakers/headphones: Speakers and headphones are output devices, which means they are devices that communicate information from the computer to the user. They allow you to hear sound and music. Depending on the model, they may connect to the audio port or the USB port. Some monitors also have built-in speakers.

Computer speakers

• Microphones: A microphone is a type of input device, or a device that receives information from a user. You can connect the microphone to the computer and use the computer to record sound or to communicate with another computer user over the Internet. Many computers come with built-in microphones.
• Web cameras: A web camera, or webcam, is a type of input device that can record videos or take pictures. It can also transmit video over the Internet in real time, allowing you to do video chat or video conferencing with someone in a different part of the world. Webcams are used often in business, and they also help many friends and families stay connected.

A webcam

• Joystick or game controller: A joystick is a lever that is used to control computer games. There are various other types of controllers you can use, and you can also use your mouse and keyboard to control most games.
• Digital cameras: A digital camera lets you capture a picture or video in digital form. By connecting the camera to your computer's USB port, you can transfer the images from the camera to the computer. You can then print the images, email them to a friend, or post them on the Web.
• Mobile phones, MP3 players, tablet computers, and other devices: When you buy an electronic device such as a mobile phone or MP3 player, check to see if it comes with a USB cable. If it does, this means you can connect it to your computer. With many devices, you can synchronize (or sync) them with your computer, which automatically keeps your contacts, music, and other data up-to-date whenever you connect the device to your computer.
