Output Definitions
Monitor: A monitor outputs visual information, displaying text, images, and video to the user.
Plotter: A plotter outputs high-quality, large-format graphics, drawings, and designs, often on paper or other flat materials.
Laser Printer: A laser printer outputs sharp, high-resolution text and graphics onto paper using toner and a laser-controlled electrostatic process.
Braille Printer: A Braille printer outputs tactile dots on paper, allowing visually impaired users to read text through touch.
Inkjet Printer: An inkjet printer outputs images and text onto paper by spraying tiny droplets of liquid ink.
Actuator: An actuator outputs physical motion or action by converting an electrical, hydraulic, or pneumatic signal into mechanical movement.

Storage definitions
Tape Drive: A tape drive stores large volumes of sequential digital data, primarily for backup and archival purposes, with capacities typically ranging from hundreds of GB to multiple TB per tape.
Flash Drive: A flash drive stores portable digital files using non-volatile flash memory, commonly offering capacities from a few GB to 1 TB.
Cloud Storage: Cloud storage stores digital data on remote servers accessible via the internet, with capacities ranging from a few GB (free tiers) to virtually unlimited petabytes (enterprise solutions).
CD (Compact Disc): A CD stores digital audio or general data, typically holding around 740 MB.
-
DVD (Digital Versatile Disc): A DVD stores larger amounts of digital video or data compared to a CD, with capacities typically around 4.7 GB (single-layer) or 8.5 GB (dual-layer).
-
Blu-ray: Blu-ray stores high-definition video and large data files, offering capacities of 25 GB (single-layer) or 50 GB (dual-layer).
-
Optical Drive: An optical drive reads and writes data to optical discs like CDs, DVDs, and Blu-rays, with its effective storage capacity depending on the specific disc used.
RAM (Random Access Memory): RAM temporarily stores data and program instructions actively being used by the CPU for quick access, with typical capacities ranging from 8 GB to 64 GB in modern computers.
SSD (Solid State Drive): An SSD stores digital data using flash memory for fast retrieval, commonly found in capacities from 250 GB to 8 TB or more.
HDD (Hard Disk Drive): An HDD stores large amounts of digital data magnetically on spinning platters, with typical capacities ranging from 1 TB to 20 TB or more.
Input Defintions
Mouse: A mouse inputs user movement and clicks to control a cursor and interact with graphical interfaces on a screen.
Barcode Scanner: A barcode scanner inputs encoded data from barcodes by reading their patterns of lines and spaces.
OMR Reader: An OMR (Optical Mark Recognition) reader inputs data by detecting marked positions or bubbles on specially designed forms, such as multiple-choice answer sheets.
Controller: A controller inputs commands and movements from a user to interact with and control actions within a video game or other interactive system.
RFID Scanner: An RFID (Radio-Frequency Identification) scanner inputs data by wirelessly reading information stored on RFID tags attached to objects.
Microphone: A microphone inputs sound by converting sound waves into electrical signals, which can then be recorded or processed digitally.
Webcam: A webcam inputs real-time visual images and often audio, typically for video conferencing, streaming, or security monitoring.
