Steam Turbines
Number of Words: 452 / Number of Pages: 2
... 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 drums is also a basic component,
as well as an outer casing that confines the steam to the area of the turbine
proper. In order to efficiently use this contraption, it is necessary to have a
number of stages. In each of these stages, a small amount of thermal energy is
converted to ...

Classification Analysis

... users however, is the printer.
Many people have probably used a printer before, but it is just that they
never realize it is also a form of output.
As opposed to 'output', 'input' consists of components that take in
information from the users themselves so that the computer will know the
tasks it is supposed to perform and accomplish. The keyboard is classified
as a form of input because this is where the users enter commands and text.
There are many other forms of input as well. Nonetheless, many people just
don't realize them, or are too lazy to classify them. For instance, the
mouse ...

Internet Access

... by a host, it is usually done through a LAN or with telephone lines and
modems combined with Internet software on a personal computer. Terminal access
is usually done by a telephone line and a modem and it is used with terminal-
emulation software on a personal computer. This also allows you to interact
with another computer that is an Internet host (explained later). Gateway
access is similar to terminal access, but it is provided through on-line or
similar services or other networks such as Bitnet, Fidonets, or UUCP nets that
allow users to minimally exchange e-mail with the Internet.

Microprocessors
Number of Words: 2468 / Number of Pages: 9
... Microprocessors Work. In their
book, Wyant and Hammerstrom describe a microprocessor as a factory and all of
the inner workings of the chip as the various parts of a factory (Wyant and
Hammerstrom, 71-103). Basically a microprocessor can be seen as a factory
because like a factory it is sent something and is told what to do with it. The
microprocessor factory processes information. This most basic unit of this
information is the bit. A bit is simply on or off. It is either a one or a zero.
Bits are put into 8 bit groups called bytes. The number 8 is used because it is
offers enough combinations to enc ...

Fifth Generation Computers
Number of Words: 1255 / Number of Pages: 5
... at an alarming rate. Intel has just started the release phase of it’s new Pentium III-800MHz processor. Glenn Henry is
quoted to say “Megahertz is all people care about” and this is too true. Sys Technology recently came out with what they claim as the “fastest commercially available PC”. This computer runs at an astonishing 1000 Mhz or 1 Ghz. This computer is appropriately named the Cold-Fusion 1000 due to the KryoTech refrigeration unit that runs coolant through a pipe over the CPU to keep it at a cool -40 degrees Celsius. This computer is made for graphics creators and “ultra serious game ...

The Internet
Number of Words: 1187 / Number of Pages: 5
... the whole network would become useless. Paul Baran, one of the Rand thinkers on the project, conceived the idea for a new kind of communications network that wasn't organized point-to-point, but instead was set up more like a fishnet. He believed this structure could allow information to find its own path through the network even if a section had been destroyed. His eleven-volume report for the Pentagon was eventually shelved, but younger engineers realized that he had hit on an essential idea. Although Baran's ideas were overlooked at that time, it later influenced the design used to create a small, ...

GPS: The Future Of Navigation And Technology
Number of Words: 3914 / Number of Pages: 15
... farther it's important to understand a bit more about navigation.
Since prehistoric times, people have been trying to figure out a reliable way to tell where they are, to help guide them to where they are going, and to get them back home again. Cavemen probably used stones and twigs to mark a trail when they set out hunting for food. The earliest mariners followed the coast closely to keep from getting lost. When navigators first sailed into the open ocean, they discovered they could chart their course by following the stars. The ancient Phoenicians used the North Star to journey from Egypt ...

... was supposed to operate automatically, by steam power, and require only one person there.
Babbage's computers were never finished. After Babbage, there was a temporary loss of interest in automatic digital computers.
A strong need thus developed for a machine that could rapidly perform many repetitive calculations.

Use of Punched Cards by Hollerith
A step towards automated computing was the development of punched cards, which were first successfully used with computers in 1890 by Herman Hollerith (left) and Jame ...

... in the comforts of home with less distraction. The software for PCs is extensive and the students can obtain all the information he/she needs for an assignment. The time that was spent running to the library has been cut by about ninety percent. This is due to the new and ever improving software that is produced for personal computers.
Secondly, the computer has become a strong teaching tool in many schools across the nation and maybe the world. Since the introduction of computers in the classrooms, students have shown a progression of their skills in reading and mathematics. There are many tu ...

A Technical Analysis Of Ergonomics And Human Factors In Modern Flight Deck Design
Number of Words: 3961 / Number of Pages: 15
... design can be traced as far back as the first
balloon flights, where a barometer was used to measure altitude. The Wright
brothers incorporated a string attached to the aircraft to indicate slips and
skids (Hawkins, 241). However, the first real efforts towards human factors
implementation in cockpit design began in the early 1930's. During this time,
the United States Postal Service began flying aircraft in all-weather missions
(Kane, 4:9). The greater reliance on instrumentation raised the question of
where to put each display and control. However, not much attention was being
focused on t ...
