The Evolution of Computer Technology

The Evolution of Computer Technology — page 1 — INTRODUCTION Since prehistoric times people have created tools in order to save energy and perform work faster Computers are sophisticated tools With these machines users can instantly communicate across the globe and learn new skills create diverse com munities process astronomical data get news and weather and buy and sell goods But computers are a recent addition to our history The reason for the evolution of computers is that people wanted to work faster and more effectively A common way of getting more work done is add ing more people to a job yet computers can replace the need for additional workers In addition there are certain things that computers do much better than humans Yet the human brain is capable of various higher-order thought processes like empathy cre ativity and lateral thinking that are difficult to repli cate in a computer The push toward digital computing happened after thousands of years of mathematical advances Math is an ancient field that people have attempted to make easier or faster by inventing various tools But prior to the advent of computers those tools required a great deal of manual labor for a limited output 4
