Third-Party Products
As with most operating systems, HP-UX 11i is the core of an entire suite of products,
not all of which come from HP.
Thousands of applications that run on HP-UX 11i (both on HP 9000 servers and on HP
Integrity Servers) are available from software vendors.

NOTE: The items in this list represent current terminology. A more comprehensive
list of terms is located in the “Glossary”.
Core
Represented in this document by the double-gear symbol
above, a “core,” (formerly referred to as a “CPU”) is an
individual processing unit on a processor chip (see
processor). For reasons of clarity, occasionally this
document will refer to a core as a “processing core”.
Processor
Represented in this document by a solid square
surrounding one or more symbols for a core, a “processor”
is a physical piece of silicon containing one or more cores.
