MTBF Mean Time Between Failures. A statistical term relating to

reliability as expressed in power on hours (poh). It was originally

developed for the military and can be calculated several different

ways, yielding substantially different results. The specification is

based on a large number of samplings in one place, running

continuously, and the rate at which failure occurs. MTBF is not

representative of how long a device, or any individual device is

likely to last, nor is it a warranty, but rather, of the relative reliability

of a family of products.

multisession The ability to record additional information, such as digitized

photographs, on a CD-ROM after a prior recording session has

ended.

non-interlaced A video system in which every pixel is refreshed during every

vertical scan. A non-interlaced system is normally more expensive

than an interlaced system of the same resolution, and is usually said

to have a more pleasing appearance.

nonvolatile memory A memory in which the data content is maintained whether the

power supply is connected or not.

a time. This port is more commonly used for the connection of a
