| Where
is the Internet going? |
Internet
2 is a media generated term that is meant to
imply that the electronic standards for improving the Internet
are, in fact, being improved and being worked on by a "consortium" of
businesses, governments, educational and research institutions
and leaders worldwide. Standards are thought to be developed
for:
Speed, connectivity, electronic universal
languages, technology, physical infrastructure
and so on.
In fact, they are not.

FAQs |
Some of the main organizations
running the Internet and contributing to its architecture
and use include:
-
-
- Internet
Architecture Board (IAB)
- Oversees Internet protocols and
procedures and the creation of Internet standards.
-
- W3C,
World Wide Web Consortium
- An industry consortium run by MIT

- Internet Corporation for Assigned
Names and Numbers (supersedes some IANA functions) and list
of Accredited
Registrars.
- InterNIC
at Network Solutions
- Directory and Databases.
Web
2.0 is user driven form and content on the
Web as opposed to organization driven content. From this
point of view the internet information has four primary sharing
patterns:
- one-to-one,
- one-to-many,
- many-to-many,
- and many-to-one.
Technologies to meet
all four of these design patterns are evolving and include (RSS
blogs, RSS Feeds, wikis, tagging, IM, Flickr, Twitter, MySpace,
Facebook, Social Networking sites, Shared bookmarking like del.icio.us,
and chat as examples.
In Summary - What
do users of the Internet do with the Internet?
Shopping, entertainment,
selling, banking, exchanging information, social networking,
play, advertise, pay, and much more.

year, Google compiles a huge list of its top searches; this list
is known as the Google Zeitgeist.)

| Okay
- What is the Internet? |
There
are perhaps 900 million - over a billion connected
computers that make up the Internet as backbone computers and
domain servers (Hosts) - computers with a registered IP address.
This isn't counting the temporarily connected computers that
log on and off, like the one you are using now.
As noted above, these computers talk
to each other using an electronic language TCP (transmission
control protocol) and set of rules called Internet Protocols
for identifying specific servers and sites addresses (IP for
short). There is much more to it than that, but essentially,
we use the Internet and its parts to send and receive, exchange
and share information.
By December 31, 2008, 1.574 billion
people were using the Internet according to Internet World Statistics.

| Is
the Internet the same thing as the World Wide Web? NO! |
The WWW
is a part, a small part actually, of the Internet.
It is one type of information exchange and not the most popular...just
the most talked about.
Let's look at the Internet and
distinguish it from the World Wide Web. The following chart show
the major types of information exchange protocols on the Internet.
Which is the biggest?
| WWW -
World Wide Web |
GUI
Interface for processing client requests. Uses HTTP - hypertext
transfer protocol (uses TCP/IP layer - Transmission Control
Protocol/Internet Protocol)Allows users to ask for, access
and open billions of webs pages (text and graphics) and more
billions of other types of files (sound, pdf, animations,
streaming, etc) |
| Email
| For
one-to-one or one-t-few exchanges , OR for e-mail mailing
lists up to hundreds.
|
| Listserv
| Listserv (or list
servers) subscription delivery for one-to-many exchanges
(very many, millions even), either moderated or un-moderated.
|
| IRC -
Internet Relay Chat
| Real
time (or near) text on screen communications in virtual spaces
(designed) called chat rooms. May allow use of microphones
and speakers to speak verbally. A variation is video-conferencing
|
| FTP -
File Transfer Protocol
| Upload
and download files and graphics, data from databases (banking
and payments, info in general) from one computer to another.
|
| Telnet
| Connect
to and use a remote machine's resources.
|
| Usenet
Newsgroups
| Bulletin
Boards and (threaded) Discussion posted to a Web Page
(uses "forms" or email) Also allows newsfeeds via
the groups newsreaders
|
| Social
Networking
| IM, Bogs, Photo
Sharing, wikis, dating, global bookmarking, personal sites,
syndicating info through RSS, etc.
|
| Streaming
audio and video
| Instead
of loading the large files to your hard drive your computer's
memory buffer allows you to load just enough information
from the large multimedia file to play the audio or video
as it is being received. Once played, the info is erased
from the buffer
|
| Search
Tools
| Directories,
|
| Search
Engines,
|
| and
Meta Tools (which search multiple engines and directories
at once).
|
| Server
Protocols - Note: Web browsers can speak to servers
using all these protocols as well as http
| FTP
- file transfer protocol. Transfers large files of all types
but doesn't open them.
|
| Gopher
- an early system of campus information protocols.
Evolved into Mozilla/Netscape then Windows Explorer and Firefox,
etc.
|
| NNTP
- read and distribute posted Usenet BB's. (uses TCP/IP
layer)
|
| WAIS
- document search & retrieval system.
|
| Telnet
- text based systems.
|
| SMTP
- e-mail messaging. (uses TCP/IP layer)
|
| RSS - Rich Site
Summary uses XML to syndicate a publishers info and send
it to your desktop: news headlines, stock quotes, weather
reports, etc.

|
| What are the
Internet Protocols (electronic rules and languages)
and Technologies? |
- The Internet - A network of
networks. Intranets and extranets are subsets of the Internet
that can only be viewed by certain groups.
The Internet is not just computers (the
backbone is the servers and host machines).
It is the Routers that
sort the transmission from source to destination, the Telecommunication
Systems that carry the transmissions (telephone line,
satellite, WiFi, fiberoptic lines, Cable and so on), the ISPs, aka
Internet Service Providers,that give users like use temporary
access to the Internet called Connectivity, The electronic languages,
translators and Protocols that
allow machines to speak to each other, and the Tracking
and Sorting done by the IP
Address and DNS computers.
- Intranets - Private networks
(servers, Websites, databases) sharing products, software, calendars,
front ends to databases, file and software sharing, email, and
so on. You're on one now. Often called a LAN or Local
Area Network.
- Extranets - Partnerships of
linked intranets
- WiFi - Wi-Fi is a
registered trademark specifically referring to any "wireless" local
area network (WLAN). It does not stand for Wide Fidelity. It
is radio wave frequencies requiring a transmitter and receiver.
Short range (Bluetooth) systems extend a few hundred feet and
are used for wireless household WLANs, Local "hotspot (hawknet
or coffee shop hotspots) and gaming devices (Guitar Hero controllers
on the XBOX). Longer range systems (cell phone towers0 extend
several miles and are used for cell phones, PDA, iPhones, Blackberries
and such.
- Client - A computer operated
by an information consumer aka operator (you). As a user, you
are part of the Internet, but only temporarily, and if your computer
broke down no one would know or care or be affected. Your
Computer - An access point to the Internet but not a "stop" on
the "information highway." aka the "client" in
a client-server relationship
- Server - A Computer/information
provider. It is part of the Internet "highway." AKA
the "server" in a client-server
relationship
The Client/Server Relationship -
A server is a computer
on steroids and amphetamines (fast, powerful, sleepless -
connected to the Internet 24/7) that "serves" pages
through the Internet upon request by the user operating
a client computer.

- ISP - Internet Service Provider.
A company that provides you with a connection to the Internet
servers (connectivity)
- modem/phone line - if you connect
to the Internet from you home computer, you need a modem (hardware
and software driver) and a phone line/cable/wireless connection
to send and receive messages. There are many types to choose
from - dial-up, DSL, ISDN, Frame Relay, cable, etc.
- TCP/IP - Protocol for how computers
find each other, identify themselves, and converse through electronic
transmission.
- http - hypertext
transmission protocol is how the browser on your computer finds
the webhost machine with the website you want to see and sends
it to your and opens and displays the associated files.
- Web Page - A single document
(file) on the Web
- Web Site - A collection of
related Web pages.
- Homepage - The first page you
see when you visit a site; the front door. Sometimes called or
preceded by a splash page.

| What type
of servers are on the Internet? |
Servers - Up to this point,
we have focused on web page servers, servers that primarily serve
up a certain type of file format, html files predominately and
and few other types such as jpegs and gifs (graphic formats). The
browser then displays the file as a formatted web page and places
the graphics on the page. You need other types of servers as well.
