We’re delighted to have this opportunity to convey the excitement of the world of computer systems. This is not a dry and dreary field, where progress is glacial and where new ideas atrophy from neglect. No! Computers are the product of the incredibly vibrant information technology industry, all aspects of which are responsible for almost 10% of the gross national product of the United States, and whose economy has become dependent in part on the rapid improvements in information technology promised by Moore’s Law. This unusual industry embraces innovation at a breath-taking rate. In the last 30 years, there have been a number of new computers whose introduction appeared to revolutionize the computing industry; these revolutions were cut short only because someone else built an even better computer. This race to innovate has...

...Information systems From Wikipedia, the free encyclopedia Information system (IS) is the study of complementary networks of hardware and software (see information technology) that people and organizations use to collect, filter, process, create and distribute data.[1][2][3] Information Systems encompasses a variety of disciplines such as: the analysis and design of systems, computer networking, information security, database management, and decision support systems. Information Management deals with the practical and theoretical problems of collecting and analyzing information in a business function area including business productivity tools, applications programming and implementation, electronic commerce, digital media production, data mining, and decision support. Communications and Networking deals with the telecommunication technologies. Information Systems bridges business and computer science using the theoretical foundations of information and computation to study various business models and related algorithmic processes within a computer science discipline.[4][5][6][7][8][9][10][11][12][13][14] Computer information system(s) (CIS) is a field studying computers and algorithmic processes, including their principles, their software and hardware designs, their applications, and their impact on society[15][16][17] while IS emphasizes functionality over design.[18] Any specific information system aims to support operations, management and decision making.[19] In a broad...

...CHAPTER 1 INTRODUCTION 1.1 History A forklift (also called a lift truck, a high/low, a stacker-truck, trailer loader, side loader or a fork hoist) is a powered industrial truck used to lift and transport materials. The modern forklift was developed in the 1920s by various companies including the transmission manufacturing company Clark and the hoist company Yale & Towne Manufacturing. The forklift has since become an indispensable piece of equipment in manufacturing and warehousing operations. The middle 19th century through the early 20th century saw the developments that led to today's modern forklifts. The Pennsylvania Railroad in 1906 introduced battery powered platform trucks for moving luggage at their Altoona, Pennsylvania train station. World War I saw the development of different types of material handling equipment in the United Kingdom by Ransomes, Sims and Jeffries of Ipswich. This was in part due to the labor shortages caused by the war. In 1917 Clark in the United States began developing and using powered tractor and powered lift tractors in their factories. In 1919 the Towmotor Company and Yale & Towne Manufacturing in 1920 entered the lift truck market in the United States. Continuing development and expanded use of the forklift continued through the 1920s and 1930s. World War II, like World War I before, spurred the use of forklift trucks in the war effort. Following the war, more efficient methods for storing products in warehouses were being...

...living in an information age dependent upon digital information. Digital information is electronic information, the result of computer processing. Every type of job relies upon getting information, using it, managing it, and relaying information to others. Computers enable the efficient processing and storage of information. Do not think of a computer merely as the machine with the keyboard and the mouse, although that might be true for some types of computers. Embedded computers may be inside your household appliances, the video cassette recorder, the automobile, planes, trains, power plants, water purification plants, calculators, and even inside a few toys. These embedded computers are very small. They affect our lives each day. Why, even modern traffic lights operate with computers. They are all around us. Think of additional ways in which computers affect our lives each day. Every organization somehow use(s) a computer to run the organization. Some of the places are hospitals, schools, fire department, banks, stores or supermarkets, stock exchange, police department, insurance companies, transport companies, and government agencies etc. What is a computer? A computer is many things to many people, depending on what it is being used for. At one time the computer can be a machine which processes the payroll, then it can be a machine which tabulates students’ grades, then a machine which stimulates the loading on a bridge, then it processes insurance policies, then it plays chess...
