Computer Keyboard and Proper Finger Positioning
What is keyboard?
A keyboard is a peripheral device that enables a user to input text into a
computer or any other electronic machinery.
A keyboard is an input device and is the most basic way for the user to
communicate with a computer..
3. Cont…
This device is patterned after its predecessor, the typewriter, from which
the keyboard inherited its layout, although the keys or letters are arranged
to function as electronic switches.
The keys include punctuation, alphanumeric and special keys like the
Windows key and various multimedia keys, which have specific functions
assigned to them.
4. The four types of Keyboards
1.QWERTY
QWERTY is a layout that was created for typewriting machines.
It is the combination of keys in a specific order (as the image shows).
QWERTY is an old layout. It was created in the 1870s by Christopher
Latham Sholes.
It was the first layout ever created. Even though it is an old layout,
QWERTY is still used by most people.

2. AZERTY
A keyboard layout used in France and neighboring countries.
A, Z, E, R, T and Y are the letters on the top left, alphabetic row.
AZERTY is similar to the QWERTY layout, except that Q and A are
swapped, Z and W are swapped and M is in the middle row instead of the
bottom one.

3. DVORAK
Dvorak refers to an alternate keyboard layout which is more efficient than
the standard QWERTY layout.
It rearranges the keys on the keyboard so that the highest frequency keys
are located on the home row, with lower frequency keys on the other rows.
The world record for fastest typing was set using a Dvorak keyboard.
Barbara Blackburn of Salem, Oregon, achieved cruising speeds of 150 to
170 words per minute, that's an incredible 17+ key presses per second!

4. QWERTZ
The QWERTZ keyboard can be identified by looking at the first six letters:
Q, W, E, R, T, and Z (not Y, like the QWERTY keyboard).
The left and right Ctrl keys are replaced by the Strg , German for
Steuerung.
Unlike Ctrl , which is called 'control', Strg is known as S-T-R-G, not
Steuerung.
Strg is German for Steuerung and is what the QWERTZ layout uses to
label the left and right Ctrl on the keyboard.
The Ctrl and Strg keys operate the same way.
