ANSI Keyboard Layout:

ANSI stands for the American National Standards Institute and is a keyboard layout common in the United States and some other closely related countries. The ANSI layout is characterized by its specific arrangement of keys, including the Enter key, the backspace key, and the position of the tilde (~) and backslash ().

A characteristic feature of the ANSI layout is the large Enter key, known as "Big Enter," which is vertically arranged. The ANSI layout is frequently used for computers and laptops in North American countries.

ISO Keyboard Layout:

ISO stands for the International Organization for Standardization, and the ISO keyboard layout is widespread in Europe and many other parts of the world. Compared to the ANSI layout, there are some notable differences in the ISO layout. The Enter key is wider and horizontally arranged, and the backslash key is usually to the left of the Enter key.

ISO layouts are used in many European countries, including Germany, France, and the United Kingdom. A well-known example of an ISO layout is the German QWERTZ layout.
