IPC Comunications

Glossary

BGP or Border Gateway Protocol

The core routing protocol of the Internet. Most Internet users do not use BGP directly, but most Internet service providers must use BGP to establish routing between one another. IPC Communications uses BGP to create redundancy and insure available service for our customers.

Bandwidth

The data transfer capacity of an electronic communications system. A measurement of bandwidth, primarily represents the maximum data transfer rate of a system measured in kilobits per second (Kbps) or megabits per second (Mbps).

Bits

A bit is the smallest unit of data in a computer. A bit has a single binary value, either 0 or 1. In most computer systems, there are eight bits in a byte.

Bits per second

Bits per second is a common measure of data speed for computer modem and transmission carriers. The speed in bps is equal to the number of bits transmitted or received each second. Abbreviated bps.

Byte

A byte is a unit of data that is eight binary digits long. A byte is the unit most computers use to represent a character such as a letter, number, or typographic symbol.   

Cabling

Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size.

Colocation

A colocation centre (collocation center) ("colo") or carrier hotel is a type of data center where multiple customers locate network, server and storage gear and interconnect to a variety of telecommunications and other network service provider(s) with a minimum of cost and complexity.

Ethernet

Ethernet is the most widely-installed local area network technology. The most commonly installed Ethernet systems are called 10BASE-T and provide transmission speeds up to 10 Mbps.

Fast E

In computer networking , Fast Ethernet is a collective term for a number of Ethernet standards that carry traffic at the nominal rate of 100 Mbit/s, against the original Ethernet speed of 10 Mbit/s. Of the 100 megabit Ethernet standards 100baseTX is by far the most common and is supported by the vast majority of Ethernet hardware currently produced. Full duplex fast Ethernet is sometimes referred to as "200 Mbit/s" though this is somewhat misleading as that level of improvement will only be achieved if traffic patterns are symmetrical. Fast Ethernet was introduced in 1995[1] and remained the fastest version of Ethernet for three years before being superseded by gigabit Ethernet .[2]

GIGE

IEEE 802.3ab, ratified in 1999, defines gigabit Ethernet transmission over unshielded twisted pair (UTP) category 5, 5e , or 6 cabling and became known as 1000BASE-T. With the ratification of 802.3ab, gigabit ethernet became a desktop technology as organizations could utilize their existing copper cabling infrastructure.

Initially, gigabit Ethernet was deployed in high-capacity backbone network links (for instance, on a high-capacity campus network). In 2000, Apple's Power Mac G4 and PowerBook G4 were the first mass produced personal computers featuring the 1000BASE-T connection.[1] It quickly became a built-in feature in many other computers.

Fiber gigabit Ethernet has recently been overtaken by 10 gigabit Ethernet which was ratified by the IEEE in 2002 and provided data rates 10 times that of gigabit Ethernet. Work on copper 10 gigabit Ethernet over twisted pair has been completed, but as of July 2006 , the only currently available adapters for 10 gigabit Ethernet over copper requires specialized cabling using 4-laned InfiniBand connectors and is limited to 15 m. However, the 10GBASE-T standard specifies use of the traditional RJ-45 connectors and longer maximum cable length.

Hosting

Typically refers to Web hosting or e-mail hosting. Your Web site or e-mail addresses are hosted or housed on a server. You rent space on that server monthly or early to pay for the service.

Internet Protocol

Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet.

Internet Protocol Address

A unique number consisting of four parts separated by dots. Every machine on the Internet must have a unique IP number.

Internet Protocol Telephony

IP telephony is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network. Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the traditionally-switched telephone system. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user. Much of IP telephony focuses on that challenge.

LAN

Local Area Network or a computer network limited to a specific area, usually the same building or even the floor of a building.

Megabit

Approximately one million bits. Typically used to measure data transfers. See below. Abbreviated Mb.

Megabits per second

Higher rates of data transfer are measured using megabits per second. Abbreviated as Mbps.

Megabyte

Approximately one million bytes. Used to measure memory capacity. Megabyte is usually abbreviated as M or MB.

Network

In information technology, a network is a series of points or nodes interconnected by communication paths. Networks can interconnect with other networks and even contain subnetworks.

OC-12

OC-12 is a network line with transmission speeds of up to 622.08 Mbit/s (payload: 601.344 Mbit/s; overhead: 20.736 Mbit/s).

OC-12 lines are commonly used by ISPs as WAN connections. While a large ISP would not use an OC-12 as a backbone (main link), it would for smaller, regional or local connections. This connection speed is also often used by mid-sized (below Tier 2 ) internet customers, such as web hosting companies or smaller ISPs buying service from larger ones.

Packets

A packet is the unit of data that is routed between an origin and a destination on the Internet.

Soft Phone

In computing , a softphone is a software Internet using a general purpose computer, rather than using dedicated hardware. Often a softphone is designed to behave like a traditional telephone , sometimes appearing as an image of a phone, with a display panel and buttons with which the user can interact. A softphone is usually used with a headset connected to the sound card of the PC, or with a USB phone.

T1 Line

A leased connection capable of carrying data at 1,544,000 bits per second, or 1.544 Mbps. A T-1 line will generally move a megabyte of data in less than 10 seconds. T-1 is the fastest speed commonly used to connect networks to the Internet. It is still not fast enough for full-screen, full-motion video.

 

T-3/DS-3 Line

A leased connection capable of carrying data at 45,000,000 bits per second, or 45 Mbps. This is more than enough to do full-screen, full-motion video.

U

Unit of measurement for Colocation.
1U = 1.75" of Vertical Rack Space
2U = 3.5" of Vertical Rack Space
3U = 5.25" of Vertical Rack Space
4U = 7.00" of Vertical Rack Space

VoIP

Stands for "Voice Over Internet Protocol," and is often pronounced "voip." VoIP is basically a telephone connection over the Internet. The data is sent digitally , using the Internet Protocol (IP ) instead of analog telephone lines. This allows people to talk to one another long-distance and around the world without having to pay long distance or international phone charges.

Voice over Internet Protocol, also called VoIP, IP Telephony, Internet telephony, Broadband telephony, Broadband Phone and Voice over Broadband is the routing of voice conversations over the Internet or through any other IP -based network.

Companies providing VoIP service are commonly referred to as providers, and protocols which are used to carry voice signals over the IP network are commonly referred to as Voice over IP or VoIP protocols. They may be viewed as commercial realizations of the experimental Network Voice Protocol (1973 ) invented for the ARPANET providers. Some cost savings are due to utilizing a single network to carry voice and data, especially where users have existing underutilized network capacity that can carry VoIP at no additional cost. VoIP to VoIP phone calls are sometimes free, while VoIP to public switched telephone networks, PSTN , may have a cost that's borne by the VoIP user.

There are two types of PSTN to VoIP services: -Direct Inward Dialing (DID) and access numbers. DID will connect the caller directly to the VoIP user while access numbers require the caller to input the extension number of the VoIP user.

WAN

Wide Area Network is any Internet or network that covers an area larger than a single building or campus.
