P314 Broadband Sharing Gateway with
Gateway | A gateway is a computer system or other device that acts as a translator between two |
| systems that do not use the same communication protocols, data formatting |
| structures, languages, and/or architecture. |
HDLC | HDLC |
| link layer protocol for the transmission of data over synchronous networks. |
Host | Any computer on a network that is a repository for services available to other |
| computers on the network. It is quite common to have one host machine provide |
| several services, such as WWW and USENET. |
HTTP | Hyper Text Transfer Protocol. The most common protocol used on the Internet. HTTP |
| is the primary protocol used for web sites and web browsers. It is also prone to certain |
| kinds of attacks. |
IANA | Internet Assigned Number Authority acts as the clearinghouse to assign and |
| coordinate the use of numerous Internet protocol parameters such as Internet |
| addresses, domain names, protocol numbers, and more. The IANA Web site is at |
| http://www.isi.edu/iana. |
ICMP | Internet Control Message Protocol is a message control and |
| between a host server and a gateway to the Internet. ICMP uses Internet Protocol (IP) |
| datagrams, but the messages are processed by the TCP/IP software and are not |
| directly apparent to the application user. |
Integrity | Proof that the data is the same as originally intended. Unauthorized software or people |
| have not altered the original information. |
internet | (Lower case i) Any time you connect 2 or more networks together, you have an |
| internet. |
Internet | (Upper case I) The vast collection of |
| protocols and that evolved from the ARPANET of the late 60’s and early 70’s. The |
| Internet now (July 1995) connects roughly 60,000 independent networks into a vast |
| global internet |
Intranet | A private network inside a company or organization that uses the same kinds of |
| software that you would find on the public Internet, but that is only for internal use. |
IP | Internet Protocol (currently IP version 4, or IPv4), is the underlying protocol for routing |

IPCP (PPP) | IP Control Protocol allows changes to IP parameters such as the IP address. |
ISP | Internet Service Providers provide connections into the Internet for home users and |
| businesses. There are local, regional, national, and global ISPs. You can think of local |
| ISPs as the gatekeepers into the Internet. |
LAN | Local Area Network is a shared communication system to which many computers are |
| attached. A LAN, as its name implies, is limited to a local area. This has to do more |
| with the electrical characteristics of the medium than the fact that many early LANs |
| were designed for departments, although the latter accurately describes a LAN as |
| well. LANs have different topologies, the most common being the linear bus and the |
| star configuration. |
