INTRODUCTION
The word computer is derived from the Latin word computare, which simply means to calculate, count or estimate. People who lived during the pre-19th century era, looked for easier ways to count, calculate, quantify and give account of the number of items they used for their day-to-day activities. Instead of using their fingers, along with sticks and pebbles to count and calculate, they created new devices to aid them.
