.... between two end users in a network can be divided into layers, with each layer adding its own set of special, related functions. Each user is at a computer equipped with these seven layers of function. So, in a given message between users, there will be a flow of data through each layer at one end down through the layers in that computer and, at the other end, when the message arrives, another flow of data up through the layers in the receiving computer. The actual programming and hardware that makes these seven layers of function is usually a combination of the computer OS, applications, TCP/IP and the software and hardware that enable you to put a signal on one o ....

.... the fastest growing technical jobs, software engineering tops the list. Carnegie Mellon University reports, “recruitment of it's software engineering students is up this year by over 20%.” All engineering jobs are paying well, proving that highly skilled labor is what employers want! “There is clear evidence that the supply of workers in the [unskilled labor] categories already exceeds the demand for their services,” says L. Mishel, Research Director of Welfare Reform Network. In view of these facts, I wonder if these trends are good or bad for society. “ The danger of the information age is that while in the short run it may be cheaper to replace workers w ....

.... wheel calculator. This rectangular box was called a Pascaline. It used eight movable dials to add sums up to eight figures long. Pascal's device used a base of ten to accomplish this. When the ten's dial moved one revolution, the dial representing the hundred's place moved one notch and so on. The drawback to the Pascaline, of course, was its limitation to addition. In 1694, a German mathematician named Gottfried Wilhem von Leibniz, improved the Pascaline by creating a machine that could also multiply. Leibniz's mechanical multiplier worked by a system of gears and dials. By studying Pascal's original notes and drawings, Leibniz was able to refine his machine. It wasn' ....

.... may be illegally copied and distributed annually worldwide. These copies work as well as the originals and sell for significantly less money. Piracy is relatively easy, and only the largest rings of distributors are usually caught. In addition, software pirates know that they are unlikely to serve hard jail time when prisons are overcrowded with people convicted of more serious crimes. The software industry loses more than $15.2 billion annually worldwide due to software piracy. Software piracy costs the industry: $482 every second $28,900 every minute $1.7 million ever ....

.... may ask a question: Can we make sure that the information in the computer is safe and nobody can steal it from the memory of the computer? Physical hazard is one of the causes of destroying the data in the computer. For example, send a flood of coffee toward a personal computer. The hard disk of the computer could be endangered by the flood of coffee. Besides, human caretaker of computer system can cause as much as harm as any physical hazard. For example, a cashier in a bank can transfer some money from one of his customer's account to his own account. Nonetheless, the most dangerous thief are not those who work with computer every day, but youthful amateurs who expe ....
