Digital Devices

The first ever known computer was the Electronic Numerical Integrator and Calculator (ENIAC) as seen on the left. It took up an entire room and weighed approximately 30 tons. It was designed by the U.S. Army during World War 2 to make artillery calculations. Most people now days don’t even know where computers came from or how they came about. People are more interested in the latest and fastest computers. The main uses of computers in our era are for playing games or surfing the net. The only computers which are known to younger people are Personal Computers (PC’s). PC’s are found in almost every single household. Most people cannot survive without their computers. They are used for banking, business, pleasure etc. The next invention was laptops, these were PC’s which folded up and could be used anywhere. The latest laptop development is a laptop which weighs 800 grams as seen in the picture on the right. What’s next? None of us will know until we are amazed with a new invention. They became a necessary accessory for all businessmen. Carrying around a laptop also gives the person a sense of class and status. The majority of people want computers which are smaller, better and faster. Technology which was amazing in the past is now criticized by people and people of today always want better things. The demand for technology is so high that producers are under pressure when releasing new products. Will we ever reach our limit with technology? Is their a limit? It seems that people have forgotten the intended purpose of such technology.
