4. TVs: Nowadays, many TVs include applications that let you access various types of online content, such as audio, video, movie information, etc. such as streaming any kind of video from the Internet directly onto your TV screen.


Input Devices

Input devices are used for entering data and commands into a computer. An input device allows communication with the computer system after that computer provides instructions and command or information. There are some common, useful input devices.

Keyboard: One of the most familiar input devices is the keyboard. It enables users to navigate among different apps, perform commands, and type content.

Mouse: Another crucial input device is the mouse. It gives users the ability to move the cursor across the screen, select and interact with items, and complete various other tasks.

Touchpad: Laptops frequently have touchpads, which can be used in place of a mouse. By sliding their fingers over a touch-sensitive surface, users may control the cursor with their fingers.

Trackball: A trackball is a type of pointing device where a ball stays inside a socket. For controlling the cursor, users can move the ball with their fingers or palms.

Scanner: Scanners are the most important input devices. It is used to convert physical documents, photos, or images into digital formats that can be stored or edited on a computer system.

Output Devices

Output devices are used for providing data and commands from the computer system. output device allows for the display of various information. There are some common, useful output devices. Let's explore some common and popular output devices.


Monitor: Often referred to as screens or displays, monitors represent text, photos, movies, and other graphical elements to provide visual output.

Printer: Hard copies of digital papers, photos, and other objects are produced using printers.

Speakers: Listening to music, sound, or various kinds of audio can be done through speakers, known as audio output devices.

Headphones: Similar to speakers, listening to music, sound, or various kinds of audio can be done through headphones, known as audio output devices.

Projector: With the use of projectors, you may see computer-generated pictures or movies on a larger surface, like a wall or projection screen.
