  • System Input Devices
    System Input Devices Since the computer is a digital device, all input devices must provide data in digital form. A key function of most of the devices listed below is to convert data from analog to digital form for transmission to the computer through a hardware interface (for our purposes, a port). Keyboard The keyboard is the most popular input device for a computer. It translates numbers, letters, symbols and control keys into digital data (bytes) that can be interpreted by the PC. Most English keyboards today are based on the QWERTY design, a de facto standard. It takes its name from the first six letters seen in the Standard IBM Keyboard keyboard's top first row of letters. An alternative to the QWERTY keyboard is the Dvorak keyboard, invented to achieve a more efficient method of typing, by placing keys used more often in the "home key" positions. Sadly, the Dvorak keyboard never received widespread use. Some specialist keyboards have extra function keys that perform Korean keyboard special actions when pressed. An example is a gaming keyboard. Some have fewer keys, like a chord keyboard. Keyboards may come in wireless, foldable or virtual varieties. Logitech G15 Gaming-Keyboard A Microwriter MW4 hand- held chord-keyboard > Ergonomic keyboard Mouse/Pointing Device A mouse is an input device that allows the user to point (locate) and click (select) . With the rise in graphical user interfaces, mice became the most commonly used method in controlling a computer. A mouse is used to manipulate objects and text on the computer screen. This device can be plugged in or can be cordless.

  • Input, Output & Storage
    Computer Basics 1 Identify and describe the most common input devices Identify and describe the most common output devices Identify and describe storage devices Identify and describe how input and output devices are connected to the computer 2 However, it needs help! Input, which is the data or instructions, must be entered into the computer. After the data is entered and processed, it needs to be “presented” to the user. We have special devices for these tasks and refer to them as input and output devices. 3 •Input devices enable you to input data and commands into the computer. •Output devices enable the computer to give you the results for the processed data. •Some devices can perform both of these tasks. The fax machine and modems are examples of this, as both these devices send (output) and receive (input) data over communications media. 4 Input devices enable you to input data and commands into the computer. The type of input device used is determined by the task to be completed. An input device can be as simple as the keyboard or as sophisticated as those used for specialized applications such as voice or retinal recognition. 5 • The Keyboard is the most commonly used input device for entering numeric and alphabetic data into the computer • A wide variety of computers are available: Ergonomic Wireless Specialized Security Flexible Biometric fingerprint reader 6 A pointing device is an input device that allows a user to position the pointer on the screen. The pointer can have several shapes, but the most common is an arrow.
