OpenVMS: Using A Virtual Operating System By The International Securities Exchange
Words: 961 - Pages: 4.... it was first brought into existence in 1976 as a
new operating system for Digital's new, 32-bit, virtual memory line of
computers, named VAX (Virtual Address eXtension).
The designers of OpenVMS were Dave Cutler and Dick Hustvedt, it was
designed entirely within Digital Equipment Corporation (DEC). OpenVMS is a
32-bit, multitasking, multiprocessing virtual memory operating system.
OpenVMS currently runs on Digital's VAX and Alpha computer systems.
Digital Equipment Corporation owned the operating system. It
wasn't until January 25, 1998 Compaq computers acquired Digital Equipment
at a tremendous price of 9.6 billion dollars. "Th .....

The Growing Popularity Of Computers
Words: 753 - Pages: 3.... friends, play games, plan a business, buy a car, do your homework... in fact, do whatever you want.
The PC has given the average American the kind of computing power that 10 years ago was found only in large corporations. Yet people now take this for granted -- and want more. They want to do many of the things they can do on their PC regardless of where they are or what device they are using -- whether it's a palm-size computer, a Web-enabled cell phone, an Auto PC or a smart television like WebTV. A combination of sophisticated software, powerful microprocessors, wireless technology and high-bandwidth connectivity is starting to make .....

Computers And Crime
Words: 1866 - Pages: 7.... eager, highly motivated, adventuresome, and willing to accept
technical challenges."(Shannon, 16:2) "It is tempting to liken computer
criminals to other criminals, ascribing characteristics somehow different from
'normal' individuals, but that is not the case."(Sharp, 18:3) It is believed
that the computer criminal "often marches to the same drum as the potential
victim but follows and unanticipated path."(Blumenthal, 1:2) There is no actual
profile of a computer criminal because they range from young teens to elders,
from black to white, from short to tall.
Definitions of computer crime has changed over the years as the users

As A Technology, It Is Called Multimedia
Words: 1635 - Pages: 6.... telephone services, telebanking, teleconferencing, even the complex simulations of virtual reality. This souped-up television will itself be a powerful computer. This, many believe, will be the world's biggest media group, letting consumers tune into anything, anywhere, anytime. The most extraordinary thing about the multimedia boom, is that so many moguls are spending such vast sums to develop digital technologies, for the delivering of programs and services which are still largely hypothetical.
So what is behind such grand prophecies? Primarily, two technological advances known as digitization (including digital compression), and fib .....

Online Censorship
Words: 1131 - Pages: 5.... nor publishers have control over information, and information is no longer tied to physical objects. In this ‘age of information,’ information and ideas can no longer be stopped at the physical territorial borders. We must also examine the meaning of the concept to “seek and receive” and to “impart” information. National restrictions on speech have a direct and negative impact on the ability of Internet users around the world to “seek and receive” information and ideas, as well as their right to “impart” information. For example, if citizens of one country are prohibited from discussing political issues onli .....

Computers Not The Greatest Invention Of The 20 Th Century
Words: 3455 - Pages: 13.... 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 father with his duties. This brass rectangular box, also called a Pascaline, used eight movable dials to add sums up .....

Computer Languages
Words: 489 - Pages: 2.... are very simple commands that the computer executes. To execute a line of
code in a language such as C, or C++, you would have to type in much more
sophisticated lines of code that are much more confusing than the previous two.
The format and layout of the various languages are very diverse between
some, and between others are somewhat similar. When programming in Basic the
user has to type in line numbers before each new line of code. In an updated
version of Basic called QBasic, numbers are optional. Turbo pascal does not
allow the user to input numbers, it has preset commands that seperate each part
of the program. This is .....

The Computer
Words: 1532 - Pages: 6.... the flow of fuel, thereby increasing gas mileage. Computers also entertain, creating digitized sound on stereo systems or computer-animated features from a digitally encoded laser disc. Computer programs, or applications, exist to aid every level of education, from programs that teach simple addition or sentence construction to advanced calculus. Educators use computers to track grades and prepare notes; with computer-controlled projection units, they can add graphics, sound, and animation to their lectures. Computers are used extensively in scientific research to solve mathematical problems.

Maglev Consequences
Words: 689 - Pages: 3.... 1990, with deregulation and consumer
demand for fast inner-city travel leading to lower airline fares, commercial air
traffic has increased by 56 percent. Adding to the congestion and delay is
increased commuter and regional air traffic. Those short distance flights take
valuable landing slots that could be used for larger planes on more profitable,
longer flights. With the maglev vehicles the shorter trips excluding access
time can be cut a lot. With a study of 16 major corridors of travel, less than
300 miles in length, they studied how well the maglev vehicles could help, and
in 10 out of the 16 the time could be cut at least sligh .....

The Electronic Computer
Words: 1885 - Pages: 7.... we can now buy a machine that will not only do our arithmetic. In addition, this machine helps us think, write, draw, play music, learn, keep records and retrieve information. It is that we are using every day.
The idea of an automatic computing machine can be traced back to the mid-nineteenth century. But it was only in the 1904s, when electronics was applied to the task of automatic computing, that fast, reliable computers became possible. Early computers were used mainly for scientific and technical calculations. In the 1950s, businesses, universities and government began using computers to store and process such nonmathematical data .....
