and less expensive so that they were able to be sold to the public. With the invention of the transistor developers were able to create the first personal computer. The transistor also helped to create the integrated circuit or microchip. An integrated circuit is a set of electrical circuits on one plate or chip. The microchip really revolutionized the computer. Cost is low because the chips‚ with all their components‚ are printed as a unit by photo-lithography rather than being constructed one

Computer development is often referred to the different generations of computing devices. With each generation which includes the first to the fifth‚ significant changes have occurred resulting in lighter‚ cheaper‚ powerful‚ more efficient and convenient devices. This change in computing devices has caused businesses to rethink and revamp the ways they operate to meet consumer demands‚ reduce cost and compete efficiently. This paper will also examine computer- based information system and the impact

Introduction: Computer Generations History of development of computers down the years is referred as Computer Generations. A generation refers to research and development done to improve the performance of computers. It also refers to the new technical breakthroughs and advancements in computers. A generation has significantly decreased the size of computers and increased the performance. With the increase in speed‚ power and memory and decrease in size‚ each generation has brought down the cost

Pentium Intel released its original Pentium Processor‚ also known as the Pentium 1‚ on March 22‚ 1993. The Pentium 1 replaced the Intel486 as Intel’s mainstream microprocessor for personal computing applications. While the Pentium 1 processors were specifically designed for use in desktop computers‚ later members of the Pentium family could accommodate laptops and other mobile devices. Reviewing some of the Pentium 1’s specifications can help you better understand the microprocessor’s capabilities

INTRODUCTION For years‚ infrared LED has been merely a system for piping light around corners and into the inaccessible places to allow the hidden to be lighted. But now‚ infrared LED has evolved into a system of significantly greater importance and use. Throughout the world‚ it is now being used to transmit voice‚ television and data signals as light waves. Its advantages as compared with conventional coaxial cable or twisted wire pairs are manifold. As a result‚ millions of dollars are being spent

Brief History of Library Automation: 1930-1996 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
