- 2. Introduction Introduction Computers interact with users and other systems through input and output devices. These devices enable communication by allowing users to input data and receive output in various formats.
- 3. Input Devices Input Devices Input devices are hardware components that allow users to enter data and commands into a computer system. These devices act as a bridge between the user and the computer, enabling interaction and communication.
- 4. Output Devices Output Devices Output devices are hardware components that receive data from a computer and convert it into a form that users can understand, such as visual, audio, or printed output. These devices display or present the results of a computer’s processing.
- 5. Difference Difference Between Between Input and Input and Output Output Devices Devices 01. 02. 03. Input Devices: • Used to enter data and commands into a computer Output Devices: • Used to display, print, or present processed data.. Input Devices: • Transfers data into the system for processing. Output Devices: •Transfers data out of the system in a userfriendly format. Input Devices: •Examples: Keyboard, Mouse, Scanner, Microphone, Joystick. Output Devices: • Examples: Monitor, Printer, Speaker, Projector, Headphones.
- 6. • Can Be Peripheral Devices – Many input and output devices are external peripherals, such as keyboards, printers, and monitors, which enhance the computer’s functionality. • Work Together for Functionality – Some devices serve both as input and output devices, like touchscreens (input via touch, output via display) and speakers with microphones (input through the mic, output through the speaker). • Hardware Components – Both input and output devices are external or built-in hardware components that facilitate interaction between the user and the computer. • Essential for Communication – Input devices send data into the computer, while output devices present processed data, making them essential for user- computer interaction. • Connected to the Computer – Both types of devices are connected to the computer via wired (USB, HDMI, etc.) or wireless (Bluetooth, Wi-Fi) connections. similarities similarities between between input and input and output output devices devices
