Christopher Sholes invented the first typewriter keyboard in 1868, arranging the keys in a "QWERTY" layout still used today. Each keyboard key contains a switch that registers a keystroke signal which is converted by the keyboard's chip into a scan code and transmitted to the computer. While keyboard size has remained consistent to fit human hands, designs have evolved to be more ergonomic, and new virtual and foldable keyboards have been introduced.

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.
E ball technology
The document describes the E-Ball, a spherical computer concept that would be the smallest PC design. The E-Ball was proposed by Apostol Tnokovski and would have a diameter of only 6 inches. It would contain all the elements of a conventional computer, like a dual-core processor, RAM, hard drive, and integrated graphics and sound card, within its small aluminum and plastic body. Users would interact with the E-Ball using a projected virtual laser keyboard and wireless optical mouse.
AN OVERVIEW ON KEYBOARD AND MOUSE
The keyboard and mouse are the most commonly used input devices for computers. The keyboard was one of the earliest peripherals and includes character keys, modifier keys, function keys, and a numeric keypad. Mice enable users to input commands and navigate screens. There are different types of keyboards including ergonomic, wireless, gaming, and membrane keyboards which vary in key layout, size, and connectivity.
Computer Keyboards
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.

Succession “Losers”: What Happens to Executives Passed Over for the CEO Job?
Succession “Losers”: What Happens to Executives Passed Over for the CEO Job? Stanford GSB Corporate Governance Research Initiative
This document summarizes a study of CEO succession events among the largest 100 U.S. corporations between 2005-2015. The study analyzed executives who were passed over for the CEO role ("succession losers") and their subsequent careers. It found that 74% of passed over executives left their companies, with 30% eventually becoming CEOs elsewhere. However, companies led by succession losers saw average stock price declines of 13% over 3 years, compared to gains for companies whose CEO selections remained unchanged. The findings suggest that boards generally identify the most qualified CEO candidates, though differences between internal and external hires complicate comparisons.keyboard
The document discusses the history and development of the computer keyboard. It began with Christopher Latham Scholes' 1873 invention of the first commercially successful typing machine, which had an alphabetically ordered keyboard layout. This caused jamming issues, so Scholes redesigned it with the most common keys spaced farther apart, creating the QWERTY keyboard layout still used today. The document also briefly describes different types of keyboards like wireless, USB, and laptop keyboards, as well as the basic parts that make up a keyboard like function keys, alphanumeric keys, cursor keys, and numeric 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.
Keyboards
Keyboards have evolved from typewriters to become an essential computer input device. While the basic keyboard layout has remained similar, modern keyboards allow users to perform more functions, are powered by electricity rather than manually, and have larger key spaces for easier typing. Christopher Latham Sholes invented the first keyboard design in 1868 to be used with early typewriters, though the technology has since been greatly advanced to integrate with computers through switch and circuitry translations of key presses into digital signals.

Keyboard history
The document traces the evolution of the computer keyboard from its origins in the typewriter. It describes how Christopher Scholes patented the first typewriter in 1868, which had keys arranged in two rows. Over subsequent years and prototypes, Scholes and others worked to improve the layout, resulting in a four-row keyboard in 1872 that was close to the modern layout. This four-row design went into mass production in 1873 as the Remington No. 1 typewriter. The QWERTY keyboard layout was established by 1878. As computers developed through the 20th century, keyboards added additional keys and became separate input devices, resulting in the extended 101-key keyboard used today.

Keyboard
The keyboard is an input device used to type documents, access menus, play games, and perform other tasks. It contains keys called keycaps that are arranged in a QWERTY layout on most keyboards. Keyboards standardly have around 100 keys organized into groups for alphanumeric keys, numbers, functions, modifiers, and cursor movement. Ergonomic keyboards are designed to reduce injuries from long periods of use by keeping hands farther apart and aligned with the forearms. Variants include illuminated keyboards with light-up keys and customizable keyboards like the Optimus keyboard.
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.
Computer project
First, we cut the base of the keyboard from thermocol and wrapped it in chart paper. Then we cut individual keys from thermocol and wrapped them in white paper before pasting them onto the base. Finally, we wrote numbers and drew symbols on the keys. In this way, our keyboard was ready.
Keyboard and its uses
A computer keyboard is an electronic device that contains letters, numbers, symbols and characters used to input data into a computer. There are different types of keyboards including multimedia keyboards with media buttons, mechanical keyboards that make noise when keys are pressed, wireless keyboards that connect via Bluetooth or radio frequency, and virtual keyboards that appear on screens. Keyboards are also classified by their size and usage, such as ergonomic keyboards designed for comfort, gaming keyboards with fewer keys, and laptop-sized keyboards with condensed keys. The most common keyboard is the QWERTY keyboard, which was designed for typewriters. New keyboard technologies include backlit keys, flexible silicone designs, and augmented reality interfaces.
Parts of Keyboard
The document defines and describes the functions of various keyboard keys, including:
- The Esc key cancels or aborts operations
- TAB advances between form fields or indents paragraphs
- Alt and Ctrl keys modify the functions of other keys when pressed simultaneously
- The spacebar creates a space between characters
- Enter/return executes commands and moves the cursor to a new line
- Arrow keys move the cursor in a specified direction

Task2
The document discusses human-computer interfaces and ergonomic design principles. It explains that ergonomic design aims to optimize products for human use by taking into account human characteristics and ensuring comfortable long-term use. Typical human-computer interface devices like keyboards, mice and game controllers are designed ergonomically so they can be used easily and don't cause user fatigue, stress or injury over prolonged periods. User testing and feedback are important parts of the design process.

Here are the answers to the questions in my own words:
1. The five major groups of keys on most standard keyboards are: alphanumeric keys, modifier keys, numeric keypad, function keys, and cursor movement keys.
2. Most standard keyboards are called 'QWERTY' keyboards because the first six letters on the top left row of letters spell out QWERTY. This specific letter arrangement has been used on keyboards since the late 1800s.
3. The CTRL key is a modifier key that modifies the input of other keys pressed with it. When you hold down the CTRL key and press another key, it changes the input or command associated with that second key.
4. The purpose of the mouse pointer
Keyboard
This document provides an overview of keyboards, including their history and types. It begins by defining a keyboard as a device that uses an arrangement of buttons to correspond to written symbols. It then describes how a keyboard works, with a key matrix that sends signals to the computer processor. The document outlines the evolution of keyboards from the 1868 typewriter to developments in 1956-1981 with early computers. It introduced specialized command keys and standardized layouts.

The Keyboard
- 1. The KeyboardBy Dylan B
- 2. Inventors Christopher Latham Sholes created the typewriter keyboard in 1868. Seven years later Christopher Sholes with the help of Amos Densmore rearranged the keyboard to make the common “QWERTY” keyboard in 1875 which is still used today. Christopher Sholes
- 3. How Does It Work? Each key on the keyboard has an electrical switch, which closes an electrical circuit. This creates a keystroke signal, which is processed by the keyboard's onboard processing chip. This chip then converts the keystroke into what is known as a "scan code." This scan code is transmitted to the computer, which then processes the scan code into either part of a system command, or displays it in the currently selected text entry field.
- 4. How Has The Size Changed? In some designs the keyboard has become smaller but most new keyboards are created the same size. The keyboard stays the same size to be the same size as your fingertips.
- 5. How The Design Changed? The keyboard has changed its design in many ways since being created. But rarely changed size. The Ergonomic Keyboard. Designed to minimize muscle strain in the fingers and hands.
- 6. Types of Keyboards Virtual keyboards like the one below project a full-size keyboard onto a flat surface. Sensors in the projector determine what keys have been pressed. Foldable Keyboard Made of soft plastic for easy travel. These are waterproof and are commonly used in hospitals because they can be disinfected. I-Tech Virtual Laser Keyboard
