For example, the most common plug is the power plug that connects your computer, monitor, and other devices to a power source. The picture is a desktop power cord in the United States with a  male plug end  that connects to the  wall socket  and the  female plug end  that connects to the computer or monitor. Note:  In our example of a power cord plug, this plug is different in different countries around the world. Cable and Cord A  cable  or  cord  is one or more wires in a plastic covering that allows for the transmission of  power  or  data  between devices. In the picture to the right is an example of a  CAT5  network cable. See our  cable definition for a list of types of cables that are used with computers. Wire A wire is a single strand of meta...

When was the first computer invented?

Image
There is no easy answer to this question due to the many different classifications of  computers . The first mechanical computer, created by  Charles Babbage  in  1822 , doesn't really resemble what most would consider a computer today. Therefore, this document has been created with a listing of each of the computer firsts, starting with the Difference Engine and leading up to the computers we use today. Note:  Early inventions which helped lead up to the computer, such as the  abacus ,  calculator , and tablet machines, are not accounted for in this document. When was the word "computer" was first used? First mechanical computer or automatic computing engine concept First programmable computer First concepts of what we consider a modern computer The first electric programmable computer The first digital computer The first stored program computer The first computer company First computer with program stored in memory First commercial co...
