Telecommunication
.... a switch. When the switch is down the current flows from the battery
through the key, down the wire, and into the sounder at the other end of the
line. By itself the telegraph could express only two states, on or off. This
limitation was eliminated by the fact that it was the duration of the connection
that determined the dot and dash from each other being short and long
respectively. From these combinations of dots and dashes the Morse code was
formed. The code included all the letters of the E .....

The Telephone

THE HANDSET
No matter what kind of telephone you own, there has to be some device
that allows you to talk to and listen to. This device is called the handset. The
handset is usually made out of plastic and inside it are two main components:
the transmitter and the receiver.
THE TRANSMITTER
It is the job of the transmitter to turn the air pressure created by
your sound waves to electrical signals so they can be sent to the other
telephone. The waves hit a thin sk .....

protocol), crude email programs, and news reading. Telnet made library catalogs,
online services, bulletin boards, databases and other network services available
to casual computer users, although not with the friendly graphic user interfaces
one sees today.
Each of the early internet functions could be invoked from the UNIX
prompt, however, each of them used a different client program with its own
unique problems. Internet software has since greatly matured, with mod .....

of Justice. The Department of Justice moved quickly, with Anne K. Bingaman, head
of the Antitrust Division of the DOJ, leading the way.(Check 1) The case was
finally ended on July 15, 1994, with Microsoft signing a consent
settlement.(Check 1)
The settlement focused on Microsoft's selling practices with computer
manufacturers. Up until .....

The Basics Of A Hard Drive
.... guess he must have gotten bored with the math or
something because he came up with a way to let him play tic-tack toe with the
computer, which by the way was the first came ever to be created on the computer.
Now there is one more thing you have to know about this computer, the computer
was half the size of West High Schools gym. And it was thought that when it was
ecomoical for people to own there own computer it would fill a decent size room.
Could you imagine a computer filling up your entire living r .....

The Central Processing Unit
.... Jack Kilby of Texas Instruments.
Now we have the major elements needed to produce a CPU. In 1965 a company by
the name of Intel was formed and they began to produce CPU's shortly thereafter.
Gordon Moore, one of the founders of Intel, predicted that the number of
transistor placed on each CPU would double every 18 months or so. This sounds
almost impossible, however this has been a very accutate estimation of the
evolution of CPUs. Intel introduced their first processor, a 4004, in November
of 1971. Th .....

Technology Changes Role Of Database Administrator
.... required many complex utility programs that run
in a specified order. This was a time-consuming energy draining task. (Fosdick
1995)
Databases are currently in the process of integration. Standardizing data,
once done predominately by large corporations, is now filtering down to medium-
size and small companies. The meshing of the old and new database causes
administrators to maintain two or three database products on a single network.
(Wong 1995)
Relational database management systems incorporate .....

The Computer
.... that is kept by police for easier
records or you could just use it for your own family history. The basic
structure of a computer is a keyboard, a moniter, a and case which holds all the
componets to make a computer run like a Hard drive, a Motherboard, and a Video
card. There are many other additions you can make to this such as a Modem, a
Joystick, and a Mouse.
The personal computer was developed during the year 1945 by the Americans to
help them decode enemy secret codes during the Second World War. .....

very important risk that society must face if it would enjoy the benefits of
modern technology. Two main types of computers are in use today, analog and
digital, although the term computer is often used to mean only the digital type.
Everything that a digital computer does is based on one operation the ability to
determine if a switch, or gate is open or closed. That is, the computer can
recognize only two states in any of its microscopic circuits on or off, .....

The Modem
.... even as advanced as Satellite modem. Most people now have 14.4
or 28.8 baud modems (Baud is "Slang" for Baud Rate Per Second) the reason for
the increase in 14.4 and 28.8's is that they are cheap and fairly recent and
haven't gone out of date yet. There are two types of modem external and
external modems internal plugs into a 16 bit port inside your computer and
external connects through either a serial (mouse)port or a parallel
(printer)port most people like the external modems because they don't take .....

The Dependability Of The Web

great that technological improvements are continually needed to handle the
burden that's been created from all of the people using the net.
Their are many things that can lighten the load that's been slowing down
the internet. First, it needs to have a lot better organization because with

The Evaluation Of The Microprocessor.

qualities like 24-bit physical addressing and a 16-bit data bus. The original
Apple Macintosh ,released in 1984, had the 8-MHz found at the core of it. It
was also found in the Macintosh Plus, the original Macintosh SE, the Apple
Laser-Writer IISC, and the Hewlett-Packard's LaserJet printer family. The
68000 was very efficient for its time for example it could address 16 megabytes
of memory, that is 16 more times the memory than the Intel .....

The Evolution Of The PC And Microsoft

The burning need for a PC was met in 1977, when Apple, a company formed
by Steve Jobs and Steve Wozniak, released itıs Apple II. Now the nerds were
satisfied, but that wasnıt enough. In order to catapult the PC in to a big-time
product, Apple needed to make it marketable to the average Joe. This was made
possible by Visical, the home spread sheet. The Apple II was now a true-blue
product.
In order to compete with Appleıs success, IBM needed somethi .....

The Future Of The Internet

technological advances, systems will be faster, more powerful, and capable of
doing more complicated tasks. As more people with different interests,
thoughts, and ideas get involved with the internet, there will be more
information available (Elmer-Dewitt 64). As the number of internet users
increases, the prices will gradually decrease on internet software and
organizations (Peterson 358). The best quality about the size of the in .....

The Future Of Computer Crime In America

these information sources are doing so by illegal means and are often motivated
by deviant and illegal means. It is said that at any given time the average
American has his name on an active file in over 550 computer information
databases of which nearly 90% are online, and of the 550 databases the number
comes no where close to how many time your personal information is listed in
some database in an unactive file. The "Average American" could si .....
