Glossary of Terms

Cookie
A system whereby a computer (HTTP server)
that hosts web pages sends information that is
stored by a user's computer, so that when that
user visits the same web page a second time,
the information that has been automatically
saved is transmitted back to the HTTP server.
For example, it assigns a unique number to the
information from a user and remembers part of
the information that the user has entered, so that
next time the user accesses the web page, the
same information does not need to be entered
all over again.
Ethernet
There are a variety of different types of computer
network. Ethernet is a type of network that was
developed by Xerox Corporation.
Firewall
A firewall is like a barrier between an outside
network (the Internet) and a local network (LAN).
It is a security measure that is used to prevent
unauthorized access to information by outsiders.
Firmware
Software that is used to operate a device.
Frame rate
This is an indication of how many times an
image is refreshed in a single second when
images are being displayed or moving images
are being played back. If the value (fps) is large,
the rate at which images are refreshed is faster,
but this setting is a theoretical maximum value,
and so if the images are complex, the images
may be refreshed even more slowly. The set
frame rate may not be attained for other reasons
also, such as the image loading time and the
performance of the computer being used.
FTP (File Transfer Protocol)
A protocol (communication standard) for
transmitting files via the Internet. This
communication protocol allows files and data to
be transferred via the Web, whereas previously it
was only possible using e-mail.
Hard disk
A storage device for large quantities of data that
is used by equipment such as computers. It
contains a flat disc that is coated with magnetic
particles, and this disc spins around and a
magnetized head is used to read the data stored
on the disc. The data can be read at extremely
fast speeds, giving it excellent data searching
performance.
HTML file
An HTML file is a text file that is written in the
HTML language (a language that is mainly used
to create web pages). The file extensions used
are .htm and .html.
IP address
A code that allocates "addresses" for each
individual computer and other device on the
Internet or in a network. Devices that
communicate by IP all must have an IP address
assigned to them. Devices that are connected to
the Internet are assigned a unique global IP
address so that no two devices have the same
address. IP addresses consist of a network ID
and a host ID, and the network ID identifies the
address as Class A, B or C.
JPEG2000 (Joint Photographic Experts
Group)
An image file compression standard that was
formulated by the International Organization for
Standardization (ISO). It provides higher
compression ratios and higher quality than
conventional JPEG.
LAN (Local Area Network)
A computer network that is located within a
relatively small area, such as a single floor of a
company building.
