Internet

I have a system with about the same specs that I use for testing other systems and various maintence. It is hooked up to a network via a 10mbs NIC and is slightly slower on DSL as brand new computers.

If it is possible, you might want to consider switching from cable to DSL Internet access. It will be faster and will still not tie up your phoneline.

Your cable modem relies on some rather advanced electronics and signalling to get its throughput. The protocols it uses to pass messages allow for retrying transmissions over some errors, and for some downshifting in case the signals aren't being sent or received well.

Your cable modem is probably getting a very marginal signal and sending or receiving data very slowly becasue it has to retry transmissions, re-establish its link with the device it is talking to, and frequently retry transmission.

The poor signal can be caused by a lot of different things. Perhaps there are too many devices connected to the same cable, or you have some poor cabling in your house. It might be that the signal arriving at your house is poor, as well. Even if you have a television video signal that's good enough to watch, the cable modem might be only able to transmit or receive a marginal signal.

Trying to fix the issue yourself means learning more about your cable modem and its built in software, or buying (or borrowing) another one to test as a replacement.

But why not have the cable company come back and double-check your signal strength and installation?

Most likely a bad cable modem. Call your cable modem provider and ask for a replacement.

The idea

The initial idea is credited as being Leonard Kleinrock'safter he published his first paper entitled "Information Flow in Large Communication Nets" on May 31, 1961.

In 1962 J.C.R. Licklider becomes the first Director of IPTO and gave his vision of a galactic network. In addition to the ideas from Licklider and Kleinrock, Robert Taylor helped create the idea of the network, which later became ARPANET.

Initial creation

The Internet as we know it today first started being developed in the late 1960's.

In the summer of 1968, the Network Working Group (NWG) held its first meeting chaired by Elmer Shapiro with the Stanford Research Institute (SRI) with attendees: Steve Carr, Steve Crocker, Jeff Rulifson, and Ron Stoughton. In the meeting the group discussed solving issues related to getting hosts to communicate with each other.

In December 1968, Elmer Shapiro with SRI released a report "A Study of Computer Network Design Parameters." Based on this work and earlier work done by Paul Baran, Thomas Marilland others; Lawrence Roberts and Barry Wessler helped to create the final version of the Interface Message Processor (IMP) specifications. Bolt Beranek and Newman, Inc. (BBN)was later awarded the contract to design and build the IMP sub network.

Introduction of the Internet to the general public

UCLA puts out a press release introducing the public to the Internet on July 3, 1969.

First network equipment

August 29, 1969 the first network switch and the first piece of network equipment called "IMP", which is short for (Interface Message Processor) is sent to UCLA. On September 2, 1969 the first data moves from UCLA host to the switch.

The first distributed message and network crash

On Friday October 29, 1969 at 10:30 p.m., the first Internet message was sent from computer science Professor Leonard KleinRock's laboratory at UCLA, after the second piece of network equipment was installed at SLI. This connection not only enabled the first transmission to be made, but is also considered to be the first Internet backbone.

The first message to be distributed was "LO", which was an attempt at "LOGIN" by Charley S. Kline to log into the SLI computer from UCLA. However, the message was unable to be completed because the SLI system crashed. Shortly after the crash, the issue was resolved and he was able to log into the computer.

E-mail is developed

Ray Tomlinson introduces network e-mail in 1972. The first messaging system to send messages across a network to other users.

TCP is developed

Vinton Cerf and Robert Kahn design TCP during 1973 and later publish it with the help of Yogen Dalal and Carl Sunshine in December of 1974 in RFC 675.

First commercial network

A commercial version of ARPANET known as Telenet is introduced in 1974 and considered by many to be the first Internet Service Provider (ISP).

Ethernet is conceived

Bob Metcalfe develops Ethernet idea in 1973.

TCP/IP is created

In 1978 TCP splits into TCP/IP driven by Danny Cohen, David Reed, and John Shoch to support real-time traffic. This allows the creation of UDP. TCP/IP is later standardized into ARPANET in 1983 and is still the primary protocol used for the Internet.

DNS is introduced

Paul Mockapetris and Jon Postel introduce DNS in 1984.

HTML

In 1990 Tim Berners-Lee develops HTML, which made a huge contribution to how we navigate and view the Internet today.

WWW

Tim Berners-Lee introduces WWW to the public on August 6, 1991.

Internet experiences large growth

In 1993 the Internet experienced one of its largest growths and today is accessible and used by people everywhere in the world.

don't be a member on imvu unless you want to download, it is not good to download because it takes up space in your computer. if you want to go ahead but it is not a smart choice. i am 10 years old and don't go on it. i am not allowed to download over the internet and you must be over 13 years old. but i go on ...

neopets is not safe because you need to enter your address and other personal in fo. if you are a parent these sites are recomendable but not

imvu

meez

neopets

if you are allowed to go on those sites go ahead, but im young so im not allowed. even if friends are on it, safety matters, it really does.

imvu have adult stuff so be aware

any way good luck finding a cool website but remember, if you want to and you are older than 13 read below

• press star now

• choose your character (you can cange it later)

• complete the form

when i first made my character i quit because i was too young

i know your tired from reading this so i hope this helped!!

Characteristics of the InternetThe characteristics of the Internet that affect its usefulness in teaching and learning can be divided broadly into Information and Connectivity. "The advantages arise from the Internet's enormous capacity to link participants with information and with each other" (Fahy, 2004, p. 164).

The Information and Connectivity of the Internet have unique characteristics:

• Information on the Internet is multimedia--capable of having coloured images, sound and video. These can be expensive to produce, but increasingly there are open sources of these types of content that are free of charge. Once produced, the price of distribution of the information is nominal compared to that of producing hard-copy books, CDs and films.

  One favourite source of free images is Flickr

• Information on the Internet can be hyperlinked. This permits both teachers and learners to assemble large bodies of information from a wide variety of sources without actually having to store the information in one place; e.g., on paper or a hard disk.

  Hyperlinks within information on the Internet enables users to find or cite additional sources of pertinent information.

• Information on the Internet is searchable. Search engines such as Google enable users to find information on every imaginable topic.

• Intelligent agents can be programmed to search the Internet for particular information and inform the user of the existence and location of that information. In fact, these agents can harvest pertinent information and deliver it to the user's desktop.

• Information on the Internet originates from world-wide sources. Users are no longer limited to the library, gallery, museum or video or record store in their locale.

• Users can visit The Hermitage in St. Petersburg without ever leaving their homes.

Constructivism and an emerging theory of learning, connectivism, in particular require that learners communicate with one another.

In any case, the willingness of people of all ages to engage in online communication is indicative of its potential for use in learning activities.
