years. The modern computers we are all familiar with can trace their roots back to simple computational machines that seem far removed from what we think of as a computer today. Simple Computers • By definition‚ a computer is any device capable of performing mathematical equations or calculations. Therefore‚ many simple devices such as an abacus (which dates back to at least 300 BCE) or a slide rule (first made in England in the 1630s) are the forerunners of today’s modern computers. The Calculating

Applications of computers in various fields Computers have their application or utility everywhere. We find their applications in almost every sphere of life–particularly in fields where computations are required to be done at a very fast speed and where data is so complicated that the human brain finds it difficult to cope up with. As you must be aware‚ computer now-a-days are being used almost in every department to do the work at a greater speed and accuracy. They can keep the record of all

Are We Too Dependent on Computers? Elisa M. Mata Pinales English 1301-213 Mss. Bustamante April 20‚ 2012 Texas A&M International University Abstract A great number of specialists agree to the fact that while technology improves‚ people become more dependent on it‚ which is the case of the computer. Having a computer and the knowledge to use it has a lot of advantages but also disadvantages. The use of the computer makes many things easy; you can find whatever you want on it‚ and

Main article: History of computer science Charles Babbage is credited with inventing the first mechanical computer. Ada Lovelace is credited with writing the first algorithm intended for processing on a computer. The earliest foundations of what would become computer science predate the invention of the modern digital computer. Machines for calculating fixed numerical tasks such as the abacus have existed since antiquity‚ aiding in computations such as multiplication and
