Glossary of Terms
Hewlett-Packard Precision Architecture (HP-PA) A computer architecture
expressly designed for performance, extensibility, and scalability. It can be
implemented on low-end and high-end computers across a complete family
of computers. Precision Architecture incorporates reduced instruction set
computer (RISC) technology in its architecture. Advantages include fewer
components and PC boards, high reliability, and small power supplies.
Hewlett-Packard Structured Query Language (ALLBASE/SQL) The
Hewlett-Packard relational database management system (DBMS) that
uses the industry standard Structured Query Language (SQL).
hexadecimal The base 16 numbering system. The first 10 digits are 0 through 9, and the
last 6 are A through F. When a number is written in base 16 it is preceded
by a dollar sign ("$"). For example, $F3 is the hexadecimal representation
for the decimal number 243.
hierarchical topology A point-to-point network topology. The hierarchical topology is
sometimes used with supervisory-control application, in which large
databases exist at one node, possibly along with control programs that are
accessed by nodes lower in the hierarchy. Hierarchical topologies are also
used for distributed database applications.
High Level Data-Link Control (HDLC) Types of protocols that eliminate much of the
handshaking (and resultant time-consuming line turnarounds).
histogram A graphical representation of data.
history stack The history stack is a CI table that contains, by default, the 20 most recent
commands entered at the system prompt during a session. The history
stack is used with the REDO and DO commands. To display the commands
in the history stack use the LISTREDO command.
home group A default group, within an account, where a user logs on when no specific
group is indicated.
host computer 1.A computer running a process for a user logged onto a different
computer. For example, a user logs onto system A and then uses data
communication software to start a session with system B and run a
program. System B is the host computer.
2. In a network, the computer that primarily provides services such as
computation, database access, or special programs or programming
languages, to other users on the network.
HP AdvanceNet A family of communication products, hardware and software,that allow
HP systems to communicate with each other and with equipment made by
other vendors.
HP Desk Hewlett-Packard's electronic mail product.
HPSlate An HP 3000 screen editor used to create and manipulate files.
HPSORT An HP 3000 utility program that sorts records in a file(s) and then merges
the sorted files.
HP-UX An operating system based on AT&T Bell Laboratories' implementation of
