Short for Hierarchical Storage Management, a data storage system that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as hard disk drives, are more expensive (per byte stored) than slower devices, such as optical discs and magnetic tape drives. While it would be ideal to have all data available on high-speed devices all the time, this is prohibitively expensive for many organizations. Instead, HSM systems store the bulk of the enterprise’s data on slower devices, and then copy data to faster disk drives when needed. In effect, HSM turns the fast disk drives into caches for the slower mass storage devices. The HSM system monitors the way data is used and makes best guesses as to which data can safely be moved to slower devices and which data should stay on the hard disks.
Short for Hot Standby Routing Protocol, a proprietary protocol from Cisco. HSRP is a routing protocol that provides backup to a router in the event of failure. Using HSRP, several routers are connected to the same segment of an Ethernet, FDDI or token-ring network and work together to present the appearance of a single virtual […]
Short for High-Speed Serial Interface. HSSI is a serial interface that supports transmission rates up to 52 mbps. It is used to connect routers on local area networks with wide area networks over a 680×0 or similar high-speed line. HSSI can also be used to provide high-speed connectivity between LANs, such as token ring and […]
- HyperText Markup Language - HTML
Short for HyperText Markup Language, the authoring language used to create documents on the World Wide Web. HTML is similar to SGML, although it is not a strict subset. HTML defines the structure and layout of a Web document by using a variety of tags and attributes. The correct structure for an HTML document starts […]
- HTML converter
A software program that is used to convert basic text files to HTML code.
- HTML editor
Also called an authoring tool, an HTML editor is a software program that inserts HTML code as you create a HTML file. Some editors will provide a word processing GUI enabling users to create HTML documents without knowing any HTML code.
