The QWERTY keyboard is a standard keyboard layout used primarily in English-speaking countries. It gets its name from the first six letters in the top row of keys. Designed in the 19th century for typewriters, the layout was created to reduce jamming by placing frequently used letters farther apart. Today, the QWERTY keyboard is widely used in computers, tablets, and smartphones. It allows users to type efficiently and quickly, as it has become the default layout for most devices. Variations of the layout exist for different languages, but QWERTY remains the most recognized worldwide.
