Qwerty is a keyboard design for Latin-script alphabets. A Latin–script alphabet (Latin alphabet or Roman alphabet) is an alphabet that uses letters of the Latin script. Basically the name comes from the order of the first six keys on the top left letter row of the keyboard (Q W E R T Y). The QWERTY design is based on a layout created for the Sholes and Glidden typewriter (Remington No. 1 which was the first commercially successful typewriter) and sold to E. Remington and Sons in 1873. It became popular with the success of the Remington No. 2 of 1878, and remains in widespread use.
The QWERTY layout was devised and created in the early 1870s by Christopher Latham Sholes, a newspaper editor and printer who lived in Kenosha, Wisconsin. Further in October 1867, Sholes filed a patent application for his early writing machine he developed with the assistance of his friends Carlos Glidden and Samuel W. Soulé.

In April 1870 he arrived at a four-row, upper case keyboard approaching the modern QWERTY standard, moving six vowel letters, A, E, I, O, U, and Y. And in 1873 Sholes’s backer, James Densmore, successfully sold the manufacturing rights for the Sholes & Glidden Type-Writer to E. Remington and Sons. The keyboard layout was then finalized within a few months by Remington’s mechanics and was ultimately presented:
