Understanding the WEB

For many people it’s a daily task to use the internet for business or private purposes, for improving knowledge, access bank accounts, sharing information on the big social networks, or just surfing for fun.
Since the mid-1990s the internet has a tremendous impact on culture, commerce, science, and the way how people communicate (E-Mail, Social Networks).

Less people know how the WWW really works.

Here is a short description as well as a review of the app EAW (Explain the Web) with which teachers can create some background information for their pupils.

The Internet …

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW), the infrastructure to support E-Mail, and peer-to-peer networks.

TCP/IP network access expanded again in 1986 when the National Science Foundation Network (NSFNET) provided access to supercomputer sites in the United States from research and education organizations, first at 56 kbit/s and later at 1.5 Mbit/s and 45 Mbit/s. Commercial Internet service providers (ISPs) began to emerge in the late 1980s and early 1990s. The Internet was commercialized in 1995 when NSFNET was decommissioned, removing the last restrictions on the use of the Internet to carry commercial traffic. The Internet started a rapid expansion to Europe and Australia in the mid to late 1980s and to Asia in the late 1980s and early 1990s.


The connection …

Here is an infographic about the steps to connect to a website.


The app EAW …

Explain a Website (EAW) is a specialized screencasting tool that allows recording the interaction with a website within the iOS web browser.

How does it work?

You enter the name of a website in the address bar and tap “Go” on the keyboard. The browser will display the chosen website. You can then draw on various elements of the website or highlight them, while talking. Everything will be recorded as an EAW project. You can then export the project to various cloud services or publish on YouTube.

The toolbar at the bottom of the screen contains three sets of buttons – on the left, drawing and highlighting tools, in the center – recording and playback, on the right – save/load functions.


Possible applications …

  • Teaching children about the usage of websites.

  • Discussing a website design with colleagues.


Disadvantages …

  • Only hand-written annotations are possible.
    So a touchscreen pen is an indispensable tool.
  • Annotations cannot be created as separate files referring to a specific position on the website.
  • Some more saturated colors for marking would be useful.
  • The app cannot be used in portrait mode which is often useful when explaining websites.
