Why the Number pads on Computer Keyboards and the Telephone Number Pads are reversed?????  

Basically, computer keypad design evolved from calculator keypad which design evolved from cash registers, while telephone keypad design evolved from the rotary dial. Tradition has kept them that way ever since.

The Touch-Tone phone emerged in the early 1960s. Before that, there were rotary dials, with the numbers starting at 1 at the top right and then running counterclockwise around the dial to 8-9-0 across the bottom.

The cash registers were designed with 0 at the bottom, and the numbers going up. The people who designed cash registers evidently just thought it was the obvious approach - lowest numbers at the bottom, highest numbers at the top. When calculators made their appearance, they copied the cash register format. When hand-held and electronic calculators made their appearance, they copied the keypad arrangement of the existing calculators. So, basically, computer keypad evolved from the calculator keypad which was evolved from cash register.

So that people who are used to using calculators, can find the numbers more easily.

computers are an extented form of calculators so they follow the layout of numeric keys of CALCUULATORS.

on the other hand the telephones follow there own style of arrangement just reverse to computers.
