Learn: Input, Output, and Storage Devices

Welcome!Building on your understanding of processor functions and performance, this lesson will explore Input, Output, and Storage Devices. These devices are essential for computers to interact with users and store data efficiently.

What are Input, Output, and Storage Devices?Input devices allow users to send data to the computer (e.g., keyboards, mice). Output devices let the computer display or return information (e.g., monitors, printers). Storage devices store data either temporarily or permanently (e.g., hard drives, flash drives).

Input DevicesInput devices include tools like keyboards, mice, scanners, and microphones. They collect data from the user and transmit it to the system for processing. For example, pressing a key on a keyboard sends a specific signal to the computer.

Output DevicesOutput devices display or share information processed by the computer. Examples include monitors, speakers, and printers. For instance, a monitor displays the result of computations or user commands.

Storage DevicesStorage devices save data. They can be magnetic (e.g., hard drives), optical (e.g., CDs, DVDs), or flash-based (e.g., USB drives). Magnetic storage is useful for large amounts of data, while flash storage is fast and portable.

RAM vs ROMRAM (Random Access Memory) is temporary memory that stores data while the computer is running. ROM (Read-Only Memory) is permanent memory that contains essential instructions for starting the computer, such as the BIOS.

Virtual StorageVirtual storage uses software to simulate additional memory by storing data on a hard drive temporarily. This allows the system to handle more tasks even when physical RAM is limited.

Review Time!Great work! You've learned about input devices, output devices, storage types, and virtual storage. Let's test your understanding with a few final questions.
