Random Access Memory. The main memory of a computer. Upgrading
the available RAM will often dramatically improve a PC's
performance. 128 MB of RAM is often standard for new PCs,
although double this figure is much better. RAM is now
Most digital cameras use the JPEG file format, one that
most PC users will have encountered before. JPEG is a
compressed image file enabling more images to be stored
in memory, but at a loss of quality. RAW is the raw data
from the image sensor before any processing is applied.
In essence, it is a true representation of what the image
sensor has seen. It is lossless and can capture data up
to 12 bits, which is better than typical JPEG and TIFF
formats. On the downside, a RAW file takes a great deal

images in RAW format.
Radio Data System. The LCD display on the radio will display
the radio station name and depending on the model of radio,
some program information as well
Transmission system that splits the Red, Green and Blue
signal to provide a clearer and more defined picture.
Root-Mean-Square. An amplitude measure of an electrical
signal that reflects the net power capability of the signal
or a speaker. Note that this differs from the peak power,
which reflects the maximum instantaneous power capability
Read Only Memory. Where PCs store important information
that they need to run the operating system and other software.
Unlike RAM, ROM is permanent and its contents cannot be
changed, replaced or deleted.
