This document discusses different types of internet connections and technologies. It describes how ISPs (Internet service providers) provide access to individuals and companies. It also explains WAP (Wireless Application Protocol) which standardizes how wireless devices can access the internet. Finally, it summarizes various types of internet connections including dial-up, wireless, cable, leased lines, and hotspots.

4. ISPs
An ISP (Internet service provider) is a company
that provides individuals and other companies
access to the Internet and other related services
such as Web site building and virtual hosting.

5. Wireless Application Protocol (WAP)
WAP (Wireless Application Protocol) is a
specification for a set of communication protocols
to standardize the way that wireless devices, such
as cellular telephones and radio transceivers, can
be used for Internet access, including e-mail, the
World Wide Web, newsgroups, and instant
messaging.

6. Types of Internet connections
• Dial-up Internet Access
• ISDN - Integrated Services Digital Network
• Wireless Internet Connections
• Cable
• Leased Line
• Hotspots

7. Dial-up Internet Access
Dial-up connections require users to link their
phone line to a computer in order to access the
Internet.
This particular type of connection—also referred
to as analog—does not permit users to make or
receive phone calls through their home phone
service while using the Internet.

8. Packet-Switched Networks
Packet-switched describes the type of network in
which relatively small units of data called packets
are routed through a network based on the
destination address contained within each packet.
Breaking communication down into packets allows
the same data path to be shared among many users
in the network.

11. ISDN - Integrated Services Digital
Network
• ISDN (Integrated Services Digital Network) allows users
to send data, voice and video content over digital
telephone lines or standard telephone wires.
• The installation of an ISDN adapter is required at both
ends of the transmission—on the part of the user as
well as the Internet access provider.
• There are quite a few other Internet connection
options available, including T-1 lines, T-3 lines, OC
(Optical Carrier) and other DSL technologies.

12. Wireless Internet Connections
Wireless, or Wi-Fi, as the name suggests, does
not use telephone lines or cables to connect to
the internet. Instead, it uses radio frequency.
Wireless is also an always on connection and it
can be accessed from just about anywhere.

13. Cable
Cable Internet connection is a form of
broadband access. Through use of a cable
modem, users can access the Internet over cable
TV lines. Cable modems can provide extremely
fast access to the Internet.

14. Leased Line
Leased connection is also known as direct
Internet access or Level Three connection. It is
the secure, dedicated and most expensive, level
of Internet connection. With leased connection,
your computer is dedicatedly and directly
connected to the Internet using highspeed
transmission lines. It is on-line twenty-four
hours a day, seven days a week.

15. Leased Line
T-1 lines are a popular leased line option for businesses
connecting to the Internet and for Internet Service
Providers (ISPs) connecting to the Internet backbone.
T-3 lines are dedicated phone connections supporting
data rates of about 43 to 45 Mbps. It too is a popular
leased line option. A T-3 line actually consists of 672
individual channels, each of which supports 64 Kbps. T-3
lines are used mainly by Internet Service Providers (ISPs)
connecting to the Internet backbone and for the
backbone itself.

17. Hotspots
Hotspots are sites that offer Internet access over a
wireless local area network (WLAN) by way of a
router that then connects to an Internet service
provider.
Hotspots utilize Wi-Fi technology, which allows
electronic devices to connect to the Internet or
exchange data wirelessly through radio waves.
Hotspots can be phone-based or free-standing,
commercial or free to the public.
