lit lamps represented ones and unlit lamps represented zeros. The irony of this is that people needed to perform another mathematical function to translate binary to decimal to make it readable to the user. One of the first computers was called ENIAC. It was a huge‚ monstrous size nearly that of a standard railroad car. It contained electronic tubes‚ heavy gauge wiring‚ angle-iron‚ and knife switches just to name a few of the components. It has become difficult to believe that computers have evolved

An automated library is one where a computer system is used to manage one or several of the library’s key functions such as acquisitions‚ serials control‚ cataloging‚ circulation and the public access catalog. When exploring the history of library automation‚ it is possible to return to past centuries when visionaries well before the computer age created devices to assist with their book lending systems. Even as far back as 1588‚ the invention of the French ’Book Wheel’ allowed scholars to

Lecture 1: Introduction to Programming 2013/14 Academic Year By Prof. Elijah I. Omwenga Introduction to Programming Program: The term program refers to a set of instructions that instructs a computer on what to do. Programs are Solutions to Problems. These instructions are written using programming languages. A program can instruct a computer to: – Read/ accept Input data – Calculate or compare – Store data – Write or display Output The term software refers to a computer program or set

Bernoulli numbers. Because of her work with the Analytical Engine‚ Ada Lovelace is considered to be the world’s first computer programmer. Over a hundred years later‚ the first true computer appeared in 1943 when the U.S. Army created a computer called ENIAC able to calculate artillery trajectories. This computer consisted of vacuum tubes‚ switches‚ and cables. To give it instructions‚ you had to physically flip its different switches and rearrange its cables. However‚ physically rearranging cables and
