Frage 1 Bericht

(a) Supply the names of the inventors of the following devices:

DEVICE NAME OF INVENTOR
Analytical Engine
Mechanical Digital Calculator
Slide Rule
Punched Card

(b)(i) What are input devices? (ii) List four input devices

Antwortdetails

(a) Inventors of the listed devices.

DeviceName of inventor
Analytical EngineCharles Babbage
Mechanical Digital Calculator (Pascaline)Blaise Pascal
Slide RuleWilliam Oughtred
Punched CardHerman Hollerith

Notes: Charles Babbage is also called the "father of the computer". Blaise Pascal built the first mechanical digital calculator (the Pascaline). William Oughtred invented the slide rule. The punched card for data processing is credited to Herman Hollerith (Joseph Marie Jacquard earlier used punched cards to control his weaving loom, so Jacquard is also accepted).

(b)(i) An input device is any hardware component used to enter data, instructions or signals into a computer for processing.

(b)(ii) Four input devices:

  1. Keyboard
  2. Mouse
  3. Scanner
  4. Microphone

(Other acceptable input devices: joystick, light pen, webcam, barcode reader, touch screen.)

Frage 1 Bericht

Which key on a keyboard is used to access special functions like volume control or brightness?
Antwortdetails

The key on a keyboard that is used to access special functions like volume control or brightness is the Function key. This can often be seen as the "Fn" key on many keyboards.


Here's how it works:

  • The Function key is usually located at the bottom row of the keyboard, often between the "Ctrl" and "Windows" keys.
  • When you hold down the Function key and press one of the keys in the top row, which are typically labeled F1 to F12, you can access special functions.
  • These functions vary depending on the device and manufacturer but often include controlling the brightness, adjusting the volume, toggling Wi-Fi, and other multimedia or hardware controls.

Therefore, the Function key is essential for quickly accessing these special functionalities without needing to navigate through software menus.
