In computing, the keyboard is an input device of the computer application to manual data into computer memory and computer control.
"QWERTY" is the most common scheme for alphanumeric keyboards, used in most computer keyboards but also in the typewriters. The name "QWERTY" is derived from the sequence of the letters of the first six keys on the top row of the keyboard. The QWERTY layout was patented in 1864 by Christopher Sholes.
The scheme also attempts to split the QWERTY keys between the two hands, so that while one hand is placed, the other hand hits the button. This speeds up the writing than the methods previously used.

T9, which stands for Text on 9 keys, is a patented predictive text technology for mobile phones, and it was invented to make easier and a lot faster typing text messages.
It allows words to be entered by a single keypress for each letter, as opposed to the multi-tap approach used in the older generation of mobile phones in which several letters are associated with each key, and selecting one letter often requires multiple keypresses.
As it gains familiarity with the words and phrases the user commonly uses, it speeds up the process by offering the most frequently used words first and then lets the user access other choices with one or more presses .
