All IBM Data Processing Systems, regardless of size, type, or basic use, have
certain common fundamental concepts and operational principles. This
manual presents these concepts and principles as an aid in developing a basic
knowledge of computers. The manual is designed for use in training programs
where a basic knowledge of computers is the end objective or is a prerequisite
to the detailed study of a particular IBM system.
Each section is organized to present a logical association of related concepts
and operational principles. The sections may be used in a progressive se
quence to develop a concept of the computer system, or they may be used
independently as reference material. The subject matter has been generalized
and refers to actual machines and systems as little as possible. Specific
systems are mentioned only to illustrate a general principle, not to compare
one system with another.
Throughout this manual you will be reading about data processing concepts
and devices supported by IBM. Such specifics as memory requirements,
device capacities and speeds, and special features will be discussed. However,
because of the dynamic nature of data processing, where changes and im
provements are being made at a very rapid pace, the reader is advised to refer
to the IBM Systems Reference Library and other IBM publications for the
most current information.
