Internet Protocol (IP) and many other protocols. - thousands of smaller commercial, academic,

electronic mail, online chat, and the interlinked
web pages and other documents of the World Wide
Web.

connected to the. - At the start of 1999, 206 of the world's 246
countries and territories were on the Internet
represented by an estimated 50 million hosts, 700
million web pages, and 140 million users. In mid
1998 an estimated 1 PetaByte (1 quadrillion, 10
15 bytes) per week was sent over the
Internet. - The then MCI Internet Backbone, now Cable
Wireless Backbone, alone was carrying 200
TByte/week in mid-1998 (from Vinton G. Cerf,
Sr. Vice President, Internet Architecture and
Technology, MCI WorldCom). The number of bytes
sent per week over the Internet is currently
doubling about every six to twelve months.

7Internet connectivity
- Definitions
- Having the hardware, software, and
telecommunications to enable connection to the
Internet
8Connection options
- Modem, dialup
- Updated by Carson Block Rose Nelson on July 20,
2004 - Connectivity options for dedicated circuitsthat
is, an Internet connection that is on all of
the time. - T-1
- A full T-1 Circuit has the capability of
transferring data at a speed of 1.54 MB/second.
In the old days (before bandwidth-intensive
things such as streaming video), a rule of thumb
was that a single T-1 line could serve 100 users.
- A frame relay T-1 is generally the most
affordable version of the circuit. - When the speed of a T-1 is less than 1.54 MB/sec,
it is called a fractional T-1. A 56k line is
the smallest fractional T-1 available. Cable - Cable companies, offer high-speed data services
over their cable networks. - Satellite Using a personal-sized satellite
dish, companies such as Direct TV offer download
speeds at about 400k/sec. - XDSL family Where available, DSL service can
be a strong price/performance option for
libraries.
