GIF
is an acronym
for Graphics Image Format. GIF is a popular
image format for files
published on the web. Images on the web
are predominately using either the GIF or JPEG
format. PNG is a third format used on
the web that is similar to GIF. The GIF format is recommended for noncontinuous
tone images with large sections of colors. GIF images also provide alpha
channel support for transparency and can be interlaced
to fade in. The format can also easily be imported into GIF animations.
GIFs allows for different color palettes of different sizes. A 1 bit
with 2 color palette, 2 bit with 16 colors, up to 16 bit with 64k colors.
This is advantageous when there are a small number of colors used in
an image because the size of the file can be significantly reduced.
Giga
refers to one
billion when used as a combining form in words. It is a term used to
define units of measurement in computer
memory. So in the case of the word gigabyte
means one billion bytes, but because
computer measurements are in binary code
a gigabyte is only approximately equal to one billion bytes. Gigabytes
are units of
measurement in computer memory.
A gigabyte is just over just over one billion bytes.
Here the giga is a prefix meaning one billion. A
gigabyte is only approximately equal to one billion bytes because computer
measurements are binary code. A gigabyte
is exactly 1024 megabytes.

servers are out of date because this service
has lost popularity to the web. GOSIP
is an acronym
for Government OSI Profile. It is a federal government procurement specification
for use with OSI protocols.

Graphical
User Interface (GUI)
is the interface to a computer
system where the
user can interact with symbols and images
instead of having a command line
input. Originally all computers consisted
of communicating through typed in commands. The command line is still
a powerful tool in most operating system
especially UNIX. The two contrasting
user interfaces to a computer
system are the command line interface and the Graphical User Interface. Graphics
are images
on a computer screen.
Standard formats for graphic files published
on the web include the GIF,
JPEG and PNG
formats.

These options are shown as grey on the computer
screen to indicate they are not functional
and not accessible to the user for some reason.
