Below,
you will find a comprehensive glossary of Internet and Computer terms with definitions that are helpful and easy to understand.
To find a term, click the letter of which the word begins with and scroll
alphabetically to find your term. For example, to find the definition for the
word "Media", click the letter "M", then scroll the list
alphabetically until you find "Media".

- K56Flex:
A technology developed by Lucent Technologies and Rockwell International
for delivering data rates up to 56 Kbps over plain old telephone service
(POTS). It was long believed that the maximum data transmission rate over
copper telephone wires was 33.6 Kbps, but K56flex achieves higher rates by
taking advantage of the fact that most phone switching stations are
connected by high-speed digital lines. K56flex bypasses the normal
digital-to-analog conversion and sends the digital data over the telephone
wires directly to your modem where it is decoded.
Lucent and Rockwell have announced that future K56flex modems will conform
to the new V.90 standard approved by the ITU. And users with older K56flex
modems may upgrade their modems to support V.90.
While K56flex offers faster Internet access than normal modems, there are
several caveats to using an K56flex modem:
-The high speeds are available only with downstream traffic (e.g., data sent
to your computer). Upstream traffic is delivered using normal techniques,
with a maximum speed of 33.6 Kbps.
-To connect to the Internet at K56flex speeds, your Internet Service
Provider (ISP) must have a modem at the other end that supports V.90.
-Even if your ISP supports V.90, you might not achieve maximum transmission
rates due to noisy lines.
- Kbit/s:
Stands for thousands of bits per second.
- Kerberos:
The name 'Kerberos' was derived from Greek mythology which refers to the
three-headed dog that guarded the gates of Hades. Kerberos is most widely
used in a network to provide secure network authentication. Usually to
authenticate users of the network.
- Kernel:
The central module of an operating system. It is the part of the
operating system that loads first, and it remains in main memory. Because it
stays in memory, it is important for the kernel to be as small as possible
while still providing all the essential services required by other parts of
the operating system and applications. Typically, the kernel is responsible
for memory management, process and task management, and disk management.
- Keygen:
(Key Generator). Refers to a program that will automatically generate a
registration or serial number. Its usual purpose is to eliminate software
piracy.
- Kilobyte: (KB)
This is about a thousand bytes of space. In reality, it's two to the
10th power or 1,024 bytes.
- KVM:
Keyboard-Video-Mouse switch. A piece of hardware that connects two or
more computers to a single keyboard, monitor and mouse. Imagine you have a
row of 4 computers that all serve as file servers. Why waste money buying 4
monitors, 4 keyboards and 4 mice. With a KVM switch you can connect all 4
computers to one monitor, keyboard and mouse and to switch between them when
needed.
