Computer Languages
... printing to the screen
you simply type the word 'print', in turbo pascal you would type 'writeln'.
These 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 numbe ...

Steam Turbines
... energy is decreased. This reduction in internal energy is transformed
into mechanical energy in the form of an acceleration of the particles of vapor.
The transformation that occurs, provides a large amount of available work energy.
The essential parts of all steam turbines consist of nozzles or jets
through which the steam can flow and expand. Thus, the temperature drops, and
kinetic energy is gained. In addition, there are blades, on which high pressure
steam is exerted. Stationary blades shift the steam onto rotating blades, which
provide power. Also, turbines are equipped with wheels or drums where the
blades are mounted. A shaft for these wheels or ...

... network. Facsimile machines, telephones, and computer-based switchers may be added to more complex systems.
The communications network can be as simple as a pair of coaxial cables running between the court and the jail, or as complicated as satellite transmission and reception facilities. Unless the organizations wanting to communicate are in the same building or are directly adjacent to one another, a communications network run through the telephone system is the most cost-effective approach. A T1 line (the equivalent of 24 standard voice-grade telephone circuits) or a portion of a T1 is required to run high-quality video and audio in two directions. ...

It And Retailing
... made. For example being located on the Internet means that place does not enter into the marketing mix of an e-commerce company. As its customers will not visit the business, it means having a prominent high street location is no longer of importance; in fact a business can be set up in someone’s home (if space for storage allows!). Also when considering mail order companies there is no longer the need to endure the costs of designing, printing and sending out catalogues. These factors contribute to e-commerce companies being able to offer products at greatly reduced prices as overheads have been minimised.
A company now has the ability to provide customers with ...

Reality - What It Is And How It Works
... using it as a sort of drug. This became evident when, among other people, Timothy Leary became interested in VR. This has also worried some of the researchers who are trying to create very real applications for medical, space, physical, chemical, and entertainment uses among other things. In order to create this alternate reality, however, you need to find ways to create the illusion of reality with a piece of machinery known as the computer. This is done with several computer-user interfaces used to simulate the senses. Among these, are stereoscopic glasses to make the simulated world look real, a 3D auditory display to give depth to sound, sensor lined g ...

Airbags - Pop Em' Or Keep Em'
... old, expecting more screaming. Nothing. Nothing happens. She shakes
her little girl and realizes that something is drastically wrong. Mica is
dead.
At last count, this scenario has happened 31 times. How many more
times does it have to happen before the automotive industry does something
about it? Children are not the only victims, though. Small women and the
elderly have also been killed as a result of airbags. The time has come to
ask ourselves, "Do airbags really work?"
First off, most people feel that airbags are a great safety device.
They let people walk away from an accident without a scratch, right? They
protect everybody, right? People don ...

The Millennium Bug
... 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 withstanding. It affects all languages

Online Censorship
... opinion would not only be wrong, it would be virtually impossible.
On the Internet, neither governments 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 count ...

Privacy And The Internet
... began when man uttered his first words. The question was raised again when the postal system began and then when telephones were introduced. Once again, we must apply the question to the new information superhighway, that is e-mail, telecommuting, online newsgroups, etc. The question is this: What does privacy on the internet mean?
Privacy And The Internet
Introduction
According to Bill Eager, "The Information Superhighway refers to the multitude of technologies and businesses that encompass the eletronic distribution of video, data and voice via communications networks. Currently, for individuals, the Information Superhighway refers primarily to the use o ...
