COS 101 Introduction to Computing Science - Module 5: Input

Flashcards covering key concepts related to input devices and processing in computing science.

Input

Any data and instructions entered into the memory of a computer.

Input Device

Any hardware component used to enter data, programs, commands, and user responses into a computer.

Mechanical Mouse

A pointing device that uses a rubber or metal ball underneath to detect movement.

Optical Mouse

A pointing device that uses light to detect movement and is more precise than a mechanical mouse.

Touch Screen

A display that allows users to interact with a computer by touching areas of the screen.

Digital Camera

A device that allows you to take digital pictures that can be viewed immediately and downloaded to a computer.

Resolution

The sharpness and clarity of an image; higher resolution indicates better image quality.

Scanner

A device that captures data directly from source documents.

OCR (Optical Character Recognition)

Technology that converts different types of documents, such as scanned paper documents, into editable and searchable data.

Bar Code

An identification code consisting of a set of vertical lines and spaces of different widths.

MICR (Magnetic Ink Character Recognition)

A technology used to read text printed with magnetized ink, primarily used in banking.

Ergonomic Keyboard

A keyboard designed to minimize strain on hands and wrists.

Gesture Recognition

Technology that detects human motions and can recognize actions such as sign language.

Electronic Signature

A digital version of a handwritten signature used for verification and legal purposes.

Pointing Device

A hardware component like a mouse or touchpad that allows users to interact with a computer's interface.

Typing Area

The part of the keyboard designated for text entry.
