The keyboard is an input device used to type text and numbers into programs on computers and other devices. Keyboards come in different layouts, like QWERTY and Dvorak, with QWERTY designed to reduce jamming on early typewriters but still commonly used on computers today. Modern keyboards have additional features beyond just typing letters and numbers, such as multimedia buttons for quick access to programs or volume control. Future keyboards may be flexible, project keyboard layouts using lasers, or have other innovative form factors and interaction methods.

Mice control cursor movement and come in forms like mechanical, optical, and wireless. Touchpads are touch-sensitive alternatives to mice found on laptops. Touch screens allow direct interaction through touching the display. Overall, the document provides an overview of common input hardware for interacting with computers.
Keyboard
A keyboard allows users to enter data into a computer. Computer keyboards contain alphanumeric keys for letters and numbers, punctuation keys, and special keys like function and arrow keys. The standard QWERTY keyboard layout was designed for mechanical typewriters in the 1800s to avoid jamming, though its odd arrangement does inhibit fast typing. Variations include the French AZERTY keyboard, which differs from QWERTY in key placements. Virtual keyboards project a keyboard image that can be touched instead of using physical keys.

Keyboard
The keyboard is an input device that uses an arrangement of keys or buttons to display letters, numbers, and symbols on a screen. Keyboards have changed over time from bulkier models with noisy springs under each key to lighter keyboards with better key mechanisms. A keyboard works by using a chip inside the computer that receives and decodes signals when the small rubber dome under a key is pressed, connecting conducting lines on the circuit. There are different types of keyboards for various uses such as standard keyboards, laptop keyboards with shorter keystrokes, and gaming keyboards with additional buttons.

Class ppt4.3
The mouse is a common input device used with desktop computers. It typically has two buttons and a scroll wheel, and controls the cursor on screen. The mouse allows users to point, select, drag and click items. While ideal for desktop use and requiring little training, the mouse is not well-suited for precise drawings or extensive text input. Overuse can also lead to repetitive strain injuries.
Unit 2 input-output
An input device sends data to a computer. Common input devices include keyboards, mice, touchscreens, cameras, and microphones. Keyboards typically have printed letters and symbols and pressing keys corresponds to written symbols. Keyboards come in different sizes for different devices like standard, laptop, and thumb-sized keyboards. Pointing devices like mice, touchpads, and trackballs allow users to control the cursor position on a screen. Computer vision devices like webcams and scanners can also serve as input devices by capturing images and documents.
Presentation
The document discusses different types of keyboards. It describes laptop keyboards as smaller versions of standard keyboards condensed to fit less space. Gaming keyboards contain extra features like illuminated keys and screens. Ergonomic keyboards are designed to minimize strain with considerations for easier typing. Laser/infrared keyboards project the keyboard onto a surface allowing direct typing. Rollup keyboards can be rolled up for easy transport and unrolled when needed.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).
