SYSTEM CONFIGURATIONS
•
Single system concept.
•
Different models provide a variety
of processing speeds and storage
sizes.
•
Broad range of input/output devices.
•
Uses an 8-bit coding structure to
represent data.
•
program compatibility throughout
system models.
Behind the decision to design the IBM
System/360 - a single system which
encompasses all areas of data processing
lies the awareness that apparently unre-

COMPREHENSIVE INTRODUCTION
lated applications have more similari-
ties than differences.
For example,
because of teleprocessing and other
factors, scientific applications require
high-speed input/output similar to that
required by commercial applications.
In
addition to this versatility, the
System/360, because of its modularity,
adaptability and compatibility, can
handle the many kinds of growth that
normally occur in computer
installations.
Modularity in the System/360 is
achieved through the availability of
seven models.
A typical Model 30 system
is shown in Figure 1-1.
In addition to
a choice of processing speed through'
model selection, each model offers a
choice of storage capacities.
