  • What is Keyboard? Keyboard Shapes and Keyboard Symbols
  • The keyboard, also called the keypad, is considered the most important entry point for computers and other electronic devices. Because many things on the computer and other devices come into play. We can give these commands to the computer, so we need to use a keyboard in order to do what we want on the computer.

 

  • While typewriters are the definitive ancestor of all the key-based text entry devices, the computer keyboard as a device for electromechanical data entry and communication derives largely from two utilities: teleprinters (or teletypes) and keypunches. It was through such devices that modern computer keyboards inherited their layouts.
  • As early as the 1870s, teleprinter-like devices were used for simultaneous typesetting and ticker tape. The teleprinter, in its more contemporary form, was developed from 1907 to 1910 by American mechanical engineer Charles Krum and his son Howard, with early contributions by electrical engineer Frank Pearne. Earlier models were developed by families such as Royal Earl House and Frederick G. Creed.
  • Earlier, Herman Hollerith developed the first keypunch devices, which soon evolved to include keys to text and number entry akin to normal typewriters by the 1930s

 

 

 

  • Keyboard Shapes
  • Keyboards are produced in different shapes for each language. There are many different keyboard types commonly used for each language. One of them is a Q Type Keyboard and the other is an F Type Keyboard. The most suitable type of keyboard is used because it is accepted that it is easier to adapt to the language of its own country in many government agencies and official institutions. Most of the computer users in the world have become habit to use the Q type keyboard. (QWERTY) Although there are 91 keys on the keyboard in general, the distribution of the letters in these keys is different. Standard alphanumeric keyboards have keys that are on three-quarter inch centers (0.750 inches, 19.05 mm), and have a key travel of at least 0.150 inches (3.81 mm). Desktop computer keyboards, such as 101-key US traditional keyboards or the 104-key Windows keyboards, include alphabetic characters, punctuation symbols, numbers and a variety of function keys. The internationally common 102/104 key keyboards have a smaller left shift key and an additional key between them and the letter to its right (usually Z or Y). Also the enter key is usually shaped differently.

 

  • Keyboard Symbols
  • In addition to the keys we see on the keyboards, there are also symbols that we bring to the square with functions. Two or more key combinations are used to bring these to the square. A large number of operating systems (including Windows) have extra software on how to use these keys. You can find out how to get these symbols from the keyboard option or help menu, as well as from different sources on the internet.
