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
The document discusses the basic parts and functions of a computer. It describes the central processing unit (CPU) as the "brain" of the computer that performs calculations and data transfer. The monitor is the most common output device that displays text and graphics, while the keyboard and mouse are popular input devices used to enter data and provide instructions via pointing. Other parts mentioned include speakers, which produce audio output, and liquid crystal displays (LCDs) which are commonly used in monitors and require less power than other display types. In closing, the document notes that computers have greatly changed modern life and are used for many purposes beyond just calculations.
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.
Unit 3
The document discusses the basic parts of a computer. It describes how the front of the computer case contains buttons and slots that can vary between machines. The back of the computer case has connection ports for connecting specific devices, though the arrangement can differ. Additional port types include FireWire on some Macs. Common peripherals that can plug into extra computer ports are printers, speakers or headphones, and scanners.

Types of keyboards
This presentation helps to sensitize students about the different types of keyboards. There are other types but i used the ones I thought my students would find interesting.
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.
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.

The document summarizes the E-Ball, the smallest PC ever made. It is a spherical computer that is 160mm in diameter. It contains components like a dual core processor, 2GB of RAM, 350-500GB hard drive, integrated graphics and sound card, speakers, wireless mouse, networking cards, and a webcam. It projects a holographic keyboard and can be used for presentations due to its portability and large memory.
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.
Non technical presentation
This document summarizes different types of computers: desktops are for regular use with a tower, keyboard, mouse and monitor; laptops are portable versions with integrated components and a battery; notebooks are smaller laptops for basic functions; tablets are handheld devices for web browsing and games; games consoles connect to TVs for single/multiplayer gaming; mobile phones allow calling/texting and some can browse/email as smartphones; PDAs provide wireless internet and email capabilities; servers perform specific tasks like file storage or printing; embedded computers have control functions within larger systems like appliances or vehicles.
The Keyboard
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.
Non technical presentation
The document summarizes different types of computing devices: desktop computers which consist of a monitor, keyboard, mouse and CPU and are best for regular office use; laptops which have all components built inside and use a touchpad instead of mouse; tablets which are portable touchscreen devices like iPads used for games, internet and email; games consoles which allow visual interactive gaming through a controller and also internet/TV access; mobile/smartphones which allow communication and have operating systems for internet, apps, email; and PDAs which are like smartphones but also allow video calls and photos.

Net neutrality- Indian Perspective
Net neutrality is the principle that internet service providers should treat all data on the internet equally without discrimination. This allows users free access to connect to any website without restrictions. Supporters argue this promotes innovation and free expression, while opponents say it increases costs for internet service providers. Without net neutrality, ISPs could charge different rates for different types of online content or websites. Indian citizens should demand freedom of access without interference from telecom companies to uphold net neutrality principles in India.

Computer keyboard
A keyboard is an input device that contains keys users press to enter data and instructions into a computer. Christopher Latham Sholes invented the modern keyboard design in 1868 with his patent of the typewriter. There are several types of keyboards including standard, laptop, gaming, ergonomic, laser/infrared, and rollup keyboards. Keyboards can connect via wired connections like USB or wireless connections like Bluetooth. Keyboards contain letter keys, number keys, function keys, navigation keys, and special keys like shift, tab, escape and control keys.
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.
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.

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.

LESSON-2A-Keyboard-Mouse.pptx
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
P2 computer systems
A desktop computer consists of an external monitor and base unit containing internal components. It requires a keyboard, mouse and can connect other accessories. A laptop is a portable computer with an integrated keyboard, mouse pad, monitor and sometimes camera. It can connect external components via ports. A tablet is a touchscreen portable computer with an integrated monitor and few buttons. It requires no external components. A smartphone is a portable computer that can perform most functions of a computer while also making calls and texts. Games consoles play electronic or disk games and come in many styles without conventional external components like a keyboard.
Input Devices
Input devices allow users to enter data and instructions into a computer. Common input devices include keyboards, mice, scanners, joysticks, microphones, and digital cameras. These devices convert user input into a format that computers can process. Keyboards are the primary input device for entering text. Mice are commonly used to control screen cursors and select items. Scanners are used to digitize images and documents.
Interacting With Your Computer
