Glossary 117
H
heatsink A structure, attached to or part of a semiconductor device, that can dissipate
heat to the surrounding environment.
host A system, such as a back-end server, with an assigned Internet Protocol (IP)
address and host name. The host is accessed by other remote systems on the
network.
host ID Part of the 32-bit Internet Protocol (IP) address used to identify a host on a
network.
host name The name of a particular machine within a domain. Host names always map to
a specific Internet Protocol (IP) address.
hot plug Describes a component that is safe to remove or add while the system is
running. Typically, the system must be rebooted before the hot-pluggable
component is configured into the system.
hot swap Describes a component that you can install or remove by simply pulling the
component out and putting a new component into a running system. The
system either automatically recognizes the component change and configures
it, or requires user interaction to configure the system. However, in neither case
is a reboot required. All hot-swappable components are hot-pluggable
components, but not all hot-pluggable components are hot-swappable
components.
Hypertext Transfer
Protocol (HTTP) The Internet protocol that retrieves hypertext objects from remote hosts. HTTP
messages consist of requests from client to server and responses from server to
client. HTTP is based on Transmission Control Protocol/Internet Protocol
(TCP/IP).
Hypertext Transfer
Protocol Secure
(HTTPS) An extension of HTTP that uses Secure Sockets Layer (SSL) to enable secure
transmissions over a Transmission Control Protocol/Internet Protocol
(TCP/IP) network.
I
in-band system
management Server management capability that is enabled only when the operating system
is initialized and the server is functioning properly.
