Gateway A program or piece of hardware that passes data between networks, especially between
networks that cannot talk directly to each other because they use different protocols.
HFS Hierarchical File System - A format system in which data are stored hierarchically in directories
and subdirectories (DOS), or folders within folders (Mac).
Host A computer on the Internet you may be able to log in to by using telnet, get files from by using
FTP, or otherwise make use of.
Host ID The portion of an IP address that identifies the host in a particular network. The Host ID is used
in conjunction with the Network ID to form a complete IP address.
HTML Hypertext Markup Language - HTML is used to write pages for the World W ide Web.HTML text
includes markup codes that define fonts, layout, embedded graphics, and hypertext links.
HTTP
Hypertext Transfer Protocol - These four letters at the beginning of most URLs tell the Web
server how your browser intends to communicate with it. (Two computers need to establish a
communications protocol right away, or they’ll never get around to exchanging data.) The HTTP
protocol is used to transfer a document from the server to your system.
Hyperlinks The underlined words or phrases in Web documents you cl ick on to jump to another screen or
page. Hyperlinks contain HTML-coded references that point to other Web pages, which your
browser then jumps to.
Hypermedia Hypermedia integrates text, images, vid eo, and sound into its documents. The elements of
hypermedia documents are linked in an interactive way.
Hypertext A non-sequential way of presenting information. A system of writing and displaying text that
enables the text to be linked in multiple ways, to be available at several levels of detail, and to be
powered by hyperlinks to ass ociate d documents.

electronics integrated into the drive itself. This is the standard for most personal computers.
Inherited Rights Access rights that are explicitly granted to a Camera Set are inherited by all Camera members.
Access rights that are explicitly granted to a group are inher ited by all user members of the

single network.
Internet A network of networks, the Internet is the world’s largest collection of networks that reaches
universities, government research labs, busi ness organizations, and military installations in most
of the countries around the world.
IP
Internet Protocol -IP is the workhorse protocol of the TCP/IP protocol suite. IP is responsible
for addressing and sending d atagrams across an internet. It provides an unreliable,
connectionless datagram delivery service; unreliable because there are no guarantees that an IP
datagram successfully gets to its destination, and connectionless because it doesn’t maintain
any status information about successiv e data grams. IP provides best effort service and relies on
ICMP to deliver error messages to the source. Datagrams are handled independently of all other
datagrams, so there is no guarantee they will arrive at the destination in order. Datagrams are
assembled by TCP at the destination.
IP Address The address scheme that identifies a compu ter on the Internet by a uniquest ring of numbers,
arranged in four groups separ ated by periods, e.g.,123.123.23.2. The IP address is respo nsible
for moving packets of data from node to node. The Internet authorities assi gn ranges of numbers
