1. What is
compression?
|
|
|
|
The translation of data into a format that requires
less storage space than the original data.
|
|
|
|
2. What is
a file format?
|
|
|
|
Computer files can be stored in various ways.
Just as a book can be written in many languages but contain the same information,
a file can be stored inside a computer in many different ways. File formats
are the digital equivalent of languages: in the same way that we can't
understand every language, computers cannot understand every file format.

3. What is
a pixel?
|
|
|
|
Digital images are made up of hundreds of thousands
of small squares called picture elements or pixels. The more pixels you
can fit into your image, the clearer your image will be as more pixels
mean that there is more detail in the image.
|
|
|
|
4. What
is resolution?
|
|
|
|
Resolution is a measure of the sharpness and
clarity of an image. It indicates the number of picture elements or pixels
that make up an image. The higher the resolution, the more pixels in total,
and therefore the bigger the disk space needed to store the file containing
the image.
|
|
|
|
5. What
is cropping?
|
|
|
|
To cut out or trim unneeded portions of an image
or a page is to crop.
|
|
|
|
6. What
are firewalls and proxy servers?
|
|
|
|
They are devices used to protect computer networks
and computers from intruders. They can sometimes interfere with legitimate
network activity by being over-restrictive.
|
|
|
|
7. What is matt?
|
back
to top |
|
|
Coated paper with a dull, no-gloss finish is known as matt finish.
|
|
|
|
8. What is
colour profiling? |
|
|
|
Because cameras, scanners, monitors, and printers
all use different technology to reproduce colours, they each use a slightly
different shade of red, green, and blue to each other. ICC profiles are
specifications that describe the language of colour spoken by a particular
device which allow us to convert the colour from one device to another.

|
10. What
is calibration? |
|
|
|
Calibration is the setting or correcting of
a measuring device or base level, usually by adjusting it to match or
conform to a dependably known and unvarying measure.
|
|
|
|
11. What
is DPI? |
|
|
|
Dots per inch. A measure of resolution for printers,
scanners and displays.
|
|
|
|
12. What
is Adobe Photoshop? |
|
|
|
Adobe Photoshop is an image-editing program
produced by Adobe Systems Inc. It is the industry standard tool for image
manipulation and is used extensively by both amateurs and professionals.
It is very expensive. A more affordable version is Adobe Photoshop Elements
which costs less than £100.
