They've certainly become an indispensable part of daily life for most people in our modern society. The first modern computers used analog systems, which were especially useful for solving problems and simulating dynamic systems in real time. By the 1960s, digital computers had largely replaced their analog counterparts. Later there was a similar transition from mainframe computers to personal computers. The advent of personal computers brought computers into the individual consumer's home for the first time. Rapid developments in computer and Internet technology powered an ever-expanding selection of handheld digital devices such as the Palm Pilot, BlackBerry, iPhone, and iPod. Computer chips were increasingly embedded in consumer devices of all sorts, including cars, cameras, kitchen appliances, toys, watches, and much more, reinforcing the interconnected nature of the world in which we now live.</div> <div class="label mt-20">Articles</div> <ul class="list-unstyled"> <li class="mt-20"> <a class="font-weight-bold" href="https://www.britannica.com/money/Apple-Inc">Apple Inc.</a> <div class="font-serif">American company</div> </li> <li class="mt-20"> <a class="font-weight-bold" href="https://www.britannica.com/biography/Alan-Turing">Alan Turing</a> <div class="font-serif">British mathematician and logician</div> </li> <li class="mt-20"> <a class="font-weight-bold" href="https://www.britannica.com/technology/UNIVAC">UNIVAC</a> <div class="font-serif">computer</div> </li> </ul> </div> <div class="col-100 col-sm-33 col-md-25"> <a href="/browse/Engineering"> <img loading="lazy" src="https://cdn.britannica.com/49/160349-050-FCE6B9E3/side-gold-medal-winner-Charles-Stark-Draper.jpg?w=400&h=225&c=crop" alt="Obverse side of the gold medal given to the winner of the Charles Stark Draper Prize, awarded annually by the U.S. National Academy of Engineering." class="col-100 mb-20" /> </a> <a href="/browse/Engineering" class="font-weight-bold font-16">Engineering</a> <div class="font-serif mt-10 line-clamp clamp-3">Engineering, the application of science to the optimum conversion of the resources of nature to the uses of humankind.
