11. What is the Internet?
Publicly accessible network of interconnected computers which communicate via software protocol standards
Easily accessed (via modem and phone line, ISDN, direct cable landline, satellite)
Expanding global infrastructure; is pan-national (no central control)
Regarding information delivery, the most significant change since the development of the printing press in the 15th century!
Basic Internet Terminology
What is the Internet?
The Internet is a network of computers around the world that are linked together by telecommunications in order to share information. It is a network of networks. Different types of computers make up the network. Some computers contain information(host computers) or servers, others (clients) access the host or server to retrieve needed information.
The Internet is a network of Computer Networks. Each computer on the network has a unique address, the Internet Protocol address (IP). It is made up of lots of servers and clients that hold and exchange information all over the world. The network is self organizing and self governing. There is no group that or individual that heads the network of net works. The computers are able to communicate with each other because they use a common set of rules or protocols
The protocols Transmission Control Protocol/Internet Protocol (TCP/IP) allows the connection and exchange of information between computers. There are a number of Internet protocols that make communication and information retrieval possible on the WWW.
Telecommunications:
The computers are able to communicate and exchange information because they use a common set of rules or protocols. These protocols allow us to connect to a remote computer(server) and access the information on it and perform any number of activities. The computer Networks communicate with each other.They are able to communicate because they use a common set of rules known as Internet Protocols.

12. Internet Growth Exponential growth for the last few years
In 1993, 90,000 people used the Internet; in 2002, 600 million people used the Internet; in 2007, over 1 billion people used the Internet
Hardware costs are decreasing year on year
Over the next 10 years electronic commerce will boom, reaching $100s of billions by the year 2010

16. Internet Services
The World Wide Web or a system of interlinked hypertext documents accessed via the Internet (multiple delivery options)
Search tools via WWW (search engines, databases, gateways and portals)
Communication ( )
Retrieval/information transfer (File Transfer Protocol - FTP)

17. The World-Wide Web WWW, web, W3, World-Wide Web
Often what people mean by the Internet
Based on hypertext - the ability to link text and documents dynamically and interactively
Uses hypertext markup language - HTML
The WWW is a global standard
Can use text, graphics, sound and video
Anyone can link to and make use of the web

20. INASP Cascading Workshop: Introduction to Using the Internet: Module 2
Access Speed Issues
Cables vary in speed and amount of information they can carry
Sometimes cables are slow in carrying information or lose the signal, especially if:
information must cross long distances
too much traffic on the cable
cable capacity, or bandwidth, is low
When the desktop client and the remote server are handing information back and forth, the information is being transmitted via a variety of ways. Some of these ways are wireless through broadcast signals (like radio), but most often the information is transmitted through cables of varying materials and speeds like telephone wires or fiber optic cables. You can think of these cables as pipes that, because of their varying materials and sizes and ability to handle traffic, are able to carry more or less information. The cable’s information carrying capacity is bandwidth. If you are connected to the Internet through a telephone line then your bandwidth is much lower than someone connected to the Internet through a large cable like a T1 line, and consequently you may not receive as much information as fast or you may have difficulty connecting to large resources at all.
For example, if you are trying to download a file, if you are on a high bandwidth connection, it may take only minutes. However, if you are on low bandwidth connection, it may take hours or may not download at all.
If you have used AGORA or other Internet resources and have noticed difficulties with the length of time it takes to log on, navigate to other websites, or download articles, it may be because of bandwidth. We will discuss these issues further later in the workshop.
