the main differences between the World Wide Web and the Internet are:

-The Internet is a global network connecting millions of end devices, with each computer being independent
-The internet is decentralized

-The Web is  a system of Internet servers that support specially formatted documents
-Documents are formatted in a markup language that supports links to other documents, from which  you can jump from one document to another simply by clicking on hot spots (hyperlinks).

What is Web 1?
Web 1.0 refers to the first stage in the World Wide Web, which was entirely made up of web pages connected by hyperlinks. Although the exact definition of Web 1.0 is a source of debate, it is generally believed to refer to the web when it was a set of static websites that were not yet providing interactive content. In Web 1.0, applications were also generally proprietary.

Exactly where Web 1.0 ends and Web 2.0 begins cannot be determined as this was a change that happened gradually over time as the internet became more interactive.

what is the role of an internet service providers?
they provide users with a reliable and accessible conduit for traffic and services. they also can be used to provide authentic and authoritative routing and naming information. furthermore they are used to educate customers about the threats they may face on the web.

give examples of two to three different internet service providers
-AASIP
-uno
-KCOM

give a range of prices charged
- prices for ISP varies from £42 for virgin media, £35.99 for BT

give a range of download speeds available
for virgin media, their have download speeds varying from 53.33 mbps up to 345.94 mbps.

Flowchart of connections

other services provided
-web hosting capabilities. 
-high speed access through DSL or cable modems. 
-dial-up connections.

All websites are hosted on servers. A server is a centralized computer which manages access to resources or services to clients.
What are the two different options for hosting a website? Advantages/Disadvantages:
 You can either pay for your website to be hosted by a company, or you can set-up a computer to host the website on your own network.

It is often easier to subscribe to a hosting service, as it is already configured for you. Professional hosting also usually has better performance, as your website will be hosted in a location where the server can provide resources to clients more quickly. Hosting services also offer better security options, as well as regular backups of your files so that if anything catastrophic should happen, your website can be recovered.

The more DIY approach of creating your own server could potentially be more cost efficient, however you must keep in mind additional electricity costs and the impact it could have on your network. Often, if you are running a server from a home network the website will not be able to serve many people at one time, due to the ADSL connection in homes which limits the upload speed, and therefore how quickly resources can be provided to clients. If your server is not configured properly or does not have sufficient security measures in place, it could potentially leave your network and personal files open to attack. 
 Pricing:
 Pricing varies drastically depending upon the services, security functions and storage space which you require.

The average range of hosting services cost between £1-£20 per month ]]> 2018-03-22 13:38:37 UTC https://padlet.com/tay17001125/m17btxp2e5db/wish/244983918 Timeline of the Internet tay17001125 https://padlet.com/tay17001125/m17btxp2e5db/wish/244991485 1965: Two computers at MIT Lincoln Lab communicate with one another using packet-switching technology.
1968: Beranek and Newman, Inc. unveils the final version of the Interface Message Processor specifications. BBN wins ARPANET contract.
1969: On Oct. 29, UCLA’s Network Measurement Center, Stanford Research Institute, University of California-Santa Barbara and University of Utah install nodes.
1972: BBN’s Ray Tomlinson introduces network email.
1973: Global networking becomes a reality as the University College of London and Royal Radar Establishment connect to ARPANET. The term Internet is born.
1974: The first Internet Service Provider (ISP) is born
1982: Transmission Control Protocol (TCP) and Internet Protocol (IP), as the protocol suite, commonly known as TCP/IP, emerge as the protocol for ARPANET.
1983: The Domain Name System (DNS) establishes the familiar .edu, .gov, .com, .mil, .org, .net, and .int system for naming websites.
1991: CERN introduces the World Wide Web to the public.]]> 2018-03-22 13:51:07 UTC https://padlet.com/tay17001125/m17btxp2e5db/wish/244991485 Why was the internet created? tay17001125 https://padlet.com/tay17001125/m17btxp2e5db/wish/244991730 The first workable prototype of the Internet came in the late 1960s with the creation of ARPANET, or the Advanced Research Projects Agency Network. Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to communicate on a single network.
 At the height of the Cold War, military commanders were seeking a computer communications system without a central core, with no headquarters or base of operations that could be attacked and destroyed by enemies thus blacking out the entire network in one fell swoop. ARPANET’s purpose was always more academic than military, but, as more academic facilities connected to it, the network did take on the branched structure military officials had envisioned.

Why was the Web Created?

Tim Berners-Lee, a British scientist at CERN, invented the World Wide Web in 1989. The web was originally conceived and developed to meet the demand for automatic information-sharing between scientists in universities and institutes around the world.]]> 2018-03-22 13:51:31 UTC https://padlet.com/tay17001125/m17btxp2e5db/wish/244991730
