Qwerty+Keyboards

=__ QWERTY __=

The most used modern-day keyboard layout is based on English-language. It takes its name from the first six characters seen in the far left of the keyboard's top row of letters.

The QWERTY design is based on a layout designed by C. Latham Sholes in 1874 for the Sholes and Glidden typewriter and sold to Remington in the same year, when it first appeared in typewriters. It was designed to minimize type bar clashes, became popular with the success of the Remington No. 2 of 1878, and remains in use on electronic keyboards due to the network effect of a standard layout and the failure of alternatives to provide very significant advantages.

It is often said that QWERTY was designed to "slow down" typists, this is incorrect – it was designed to prevent jams //while// typing at speed, yet some of the layout decisions, such as placing only one vowel on the home row, did have the effect of hobbling more modern keyboards.

In the QWERTY layout many more words can be spelled using only the left hand than the right hand. In fact, thousands of English words can be spelled using only the left hand, while only a couple of hundred words can be typed using only the right hand. This is helpful for left-handed people. The longest word that can be written with one hand (on the left side) is 'Stewardest'.

**__ Computer keyboards __**
The first computer terminals such as the Teletype were typewriters that could produce and be controlled by various computer codes. These used the QWERTY layouts, and added keys such as escape (ESC) which had special meanings to computers. Later keyboards added function keys and arrow keys. Since the standardization of PC-compatible computers and Windows after the 1980s, most full sized computer keyboards have followed this standard. This layout has a separate numeric keypad for data entry at the right, 12 function keys across the top and a cursor section to the right and center with keys for Insert, Delete, Home, End, Page Up, and Page Down with cursor arrows in an inverted-T shape.
