User’s Manual
Software –
In a nutshell, software is a set of instructions for the computer. A set of instructions to perform a particular task is
called a program. There are two main types of software: system software (an operating system such as Mac OS or Windows)
which controls the operation of the computer and application software (programs such as Word or Excel) which enable users
to perform tasks such as word processing, spreadsheet creation, graphics, etc.
Storage –
In computers, any equipment in which information may be kept. PCs generally use disk units and other external
storage media (diskettes, CD-ROMs, magnetic disks, etc.) for permanent storage of information.
Track at Once (TAO) –
CD authoring process where data is added one track at a time, and the data can be added at a later
time. The CD being written to, though, can only be read in the CD recorder until the disc is finalized (meaning that no more
data can be added). There is also a gap of 2 seconds added between tracks, which will be heard as noise in some audio
players.
Transfer Rate –
The rate at which the drive sends and receives data from the controller. Transfer rates for reading data from
the disk drive may not be the same as the transfer rate for writing data to the disk drive. Transfer rates are CPU dependent,
meaning that regardless of how great a transfer rate your drive is capable of, the actual transfer rate can only be as fast as
the slowest of your hard drive and computer.
UDF –
The Universal Disc Format developed by the Optical Storage Technology Association (OSTA), is a single file system for
interchange of information in the computer arena. This file system was designed to be able to handle files from all other
common file systems (computers).
Volume –
A desktop mountable storage area, may be a partition of a hard drive, a removable disk or a cartridge. Typically
measured in Megabytes or Gigabytes.
Utility –
Software designed to perform maintenance tasks on the system or its components. Examples include backup
programs, programs to retrieve files and data on disk, programs for preparing (or formatting) a disk or and resource editors.
