... central event of the 20th century is the overthrow of matter. In technology, economics, and the politics of nations, wealth -- in the form of physical resources -- has been losing value and significance. The powers of mind are everywhere ascendant over the brute force of things. In a First Wave economy, land and farm labor are the main "factors of production." In a Second Wave economy, the land remains valuable while the "labor" becomes massified around machines and larger industries. In a Third Wave economy, the central resource -- a single word broadly encompassing data, information, images, symbols, culture, ideology, and values -- is actionable k ...
... after the digital block. The user inputs controlling frequency and symmetry are also built into this control block. Therefore it is clear that the digital block can be divided into 4 distinct blocks, each with its own functionality. These blocks are the control module, counter module, filter control module and 8-bit D/A. The D/A chosen is the DAC0801LCN. It’s specifications can be found in the appendix. The layout of this design is shown below. The interconnections will be discussed later but the thickness of the lines indicates the number of bits in the bus lines. As the name suggests the control module takes user inputs, processes them and ...
... that could be moved to make calculations. The first digital computer is usually accredited to Blaise Pascal. In 1642 he made the device to aid his father, who was a tax collector. In 1694 Gottfried Leibniz improved the machine so that with the rearrangement of a few parts it could be used to multiply. The next logical advance came from Thomas of Colmar in 1890, who produced a machine that could perform all of the four basic operations, addition, subtraction, multiplication and division. With the added versatility this device was in operation up until the First World War. Thomas of Colmar made the common calculator, but the real start of computers as t ...
... between stations, but it can interconnect any number of stations that are included within the antenna beams of the satellite rather than simply the two ends of the microwave link. Computer Crime Computer crime is defined as any crime involving a computer accomplished through the use or knowledge of computer technology. Computers are objects of crime when they or their contents are damaged, as when terrorists attack computer centres with explosives or gasoline, or when a "computer virus" a program capable of altering or erasing computer memory is introduced into a computer system. Personal Computer A personal computer is a computer that is based on a microproces ...
... the hacker tries to bypass this anyway he knows how to and tries to gain access to the system. Why do they do it, well lets go to a book and see "Avid young computer hackers in their preteens and teens are frequently involved in computer crimes that take the form of trespassing, invasion of privacy, or vandalism. Quite often they are mearly out for a fun and games evening, and they get entangled in the illegal use of their machines without realizing the full import of what they are doing", I have a hard time believing that so lets see what a "hacker" has to say about what he does "Just as they were enthraled with their pursuit of information, so are we. The thr ...
... memory and file usage. A qualified system administrator should be able to tell by the amounts of memory being used and the file usage if something is going on that should not be. If a virus is found, system administrators can pinpoint the user who put the virus into the network and investigate whether or not there was any malice intended. One computer application that is becoming more widely used and, therefore, more widely abused, is the use of electronic mail or email. In the present day, illegal hackers can read email going through a server fairly easily. Email consists of not only personal transactions, but business and financial transactions. There ...
... A NUMBER OF PROGRAMS. - CAPABILITY TO RECOGNIZE A MODIFICATION PERFORMED ON A PROGRAM.(THE ABILITY TO PREVENT FURTHER MODIFICATION OF THE SAME PROGRAM UPON SUCH RECONDITION.) - MODIFIED SOFTWARE ASSUME ATTRIBUTES 1 TO 4. HOW DOES A VIRUS SPREAD: A computer virus can only be put into your system either by yourself or someone else. One way in which a virus can be put into your computer is via a Trojan Horse. -TROJAN HORSE IS USUALLY CONTAMINATED IN DISKS WHICH ARE PARTICULARY PIRATED COPIES OF SOFTWARE. IT IS SIMPLY A DAMAGING PROGRAM DISGUISED AS AN INNOCENT ONE. MANY ...
... the Internet security, especially when dealing with personal security, business security, and the government involvement to protect the users. The Internet is a new, barely regulated frontier, and there are many reasons to be concerned with security. The same features that make the Internet so appealing such as interactivity, versatile communication, and customizability also make it an ideal way for someone to keep a careful watch on the user without them being aware of it (Lemmons 1). It may not seem like it but it is completely possible to build a personal profile on someone just by tracking them in cyperspace. Every action a person does while logged onto t ...
... 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 automated, with computers (and robots) controlling the entire production process with minimal human intervention. However, CIM is typically employed at a level short of total integration. Many man ...
... work with folder icons that represent directories and subdirectories in DOS. Windows 95, unlike the Mac, logically groups data and resources. A Taskbar menu lets you call up and switch between any software application at any time. Thus feature is better than the Mac's because its use is more obvious. It clearly shows what is running and allows you to switch programs with a single click of the mouse. Control panels have been added so you can configure your hardware. There is easy access to frequently used files. You can make very long file names on Windows 95 instead of short and strange names that leave you wondering about, such as on Windows 3.x I could not name a ...
