.... it is important to understand their evolution. The abacus, which emerged about 5,000 years ago in Asia Minor and is still in use today, may be considered the first computer. This device allows users to make computations using a system of sliding beads arranged on a rack. Early merchants used the abacus to keep trading transactions. But as the use of paper and pencil spread, particularly in Europe, the abacus lost its importance. It took nearly 12 centuries, however, for the next significant advance in computing devices to emerge. In 1642, Blaise Pascal, the 18-year-old son of a French tax collector invented what he called a numerical wheel calculator to help his fa ....

He gets the connection from the local phone company. · How logging on the internet is almost like logging right onto the local telephone company. -It all boils down to, the local phone company approving the use of the internet for any means. · How phone companies are going to bring them selves down. -I feel that because of this phone companies will be the cause to their own downfall. · Methods of communication over the net -There are many ways of communicating over the net: Inter relay chat (text only) -Video/Audio: there are many net appl ....

.... computer to integrate the fragmented operations of manufacturing into a single, smoothly operating, manufacturing system with reduced total manufacturing costs and turnaround times, and improved quality is generally termed Computer-Integrated Manufacturing (CIM). Another definition that is more precise might be the utilization of computers to control the integration and flow of information between design, engineering, manufacturing, logistics, warehousing and distribution, customers and suppliers, sales and marketing activities, financial management and the overall control of the enterprise. At one extreme, a Computer-Integrated Manufacturing process may be fully automate ....

.... store the date in the following format: dd/mm/yy. This only allows 2 digits for the year. January 1, 2000 would be stored as 01/01/00. But the computer will interpret this as January 1, 1900- not 2000" (de Jager 1). The '19' is "hard-coded" into computer hardware and software. Since there are only 2 physical spaces for the year in this date format, after '99', the only logical choice is to reset the number to '00'. The year 2000 problem is unlike any other problem in modern history for several reasons. William Adams points out some of the most important ones. "Time is running out- the Year 2000 is inevitable! The problem will occur simultaneously worldwide, time zones withst ....

.... offers, or the performance of your Web host becomes unsatisfactory, or the worst possible scenario -- your Web host goes out of business. For a brick and mortar business, the biggest tragedy is probably a fire -- few people realise how large a proportion of businesses fail to re-open after a major fire. I would equate the failure of a Web host for an e-commerce site to that of a fire for a traditional store, and would expect that a similarly high proportion of Web stores would go out of business as a result. I guess that most Web merchants are complacent, either assuming that they will never have to change hosts or that if they do it will be a straightforward matter. Howeve ....

.... can be reconstituted by passing an electric current through them in the opposite direction are known as secondary cells, are rechargeable cells. The primary battery is the most common type of battery used today, invented by the French chemist Geoges Leclanche in the late 1860’s. At the time this invention was very important and helped the start of the industrial revolution. It allowed people with portable electricity. This popular invention was called the dry cell or flashlight battery. The Lechlanche cell is very similar to the dry cell we use today. The positive pole is a rode of carbon embedded in a black manganese dioxide (MnO2) and Carbon particles and the negative ....

.... ancestor is the abacus. These date back to almost 2000 years ago. It is simply a wooden rack holding parallel wires on which beads are strung. When these beads are moved along the wire according to "programming" rules that the user must memorize, all ordinary arithmetic operations can be performed (Soma, 14). The next innovation in computers took place in 1694 when Blaise Pascal invented the first digital calculating machine. It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal’s father who was a tax collector (Soma, 32). In the early 1800’s, a mathematics professor named Charles Babbage designed an automatic calcula ....

.... to imitate and, in turn they are also inclined to listen. Research has shown that young children need to enjoy repetition in order to learn. The deliberate and frequent repetition used in the Interactive doll reassures, comforts and delights a child and sets an effective stage for learning. ' liberal use of repetition, large movement, bright colors, and deliberate pace nurtures and reinforces the development of children's listening and thinking skills. The pacing and repetition of encourages children to practice fundamental skills and concepts again and again.
