3. Overview
Internet Service Providers (ISP’s), which first began to
emerge in the late 1980s and early 1990s, are the
businesses and organizations that provide users with
Internet access and related services. These providers
connect customers to customers of other service
providers by way of networks. Often, Internet Service
Providers (also called Internet Access Providers) are
companies that provide telecommunications services
including data communications access and telephone
connection. The majority of telephone companies now
function as Internet Access Providers as well. ISP’s may be
commercial, non-profit, privately owned or community-
owned.

4. Types of ISPs
Access ISPs — Employ a variety of technologies to facilitate consumers’ connection to their
network. These technologies may include broadband or dialup. Always-on types of
broadband connections comprise cable, fiber optic service (FiOS), DSL (Digital Subscriber
Line) and satellite. A number of access providers also provide email and hosting services.
Mailbox ISPs — Offer email mailbox hosting services and email servers to send, receive and store
email. Many mailbox ISPs are also access providers.
Hosting ISPs — Offer email, File Transfer Protocol (FTP), web-hosting services, virtual machines,
clouds and physical servers.
Transit ISPs —Provide large amounts of bandwidth needed to connect hosting ISPs and access
ISPs together.
Virtual ISPs (VISP) — Purchase services from other ISPs to allow customers Internet access.
Free ISPs (free nets) – Provide service free of charge and often display advertisements while
users are connected.

8. Types of link to ISP
1. Wireless
Radio frequency bands are used in place of
telephone or cable networks. One of the greatest
advantages of wireless Internet connections is the
“always-on” connection that can be accessed from
any location that falls within network coverage.
Wireless connections are made possible through
the use of a modem, which picks up Internet signals
and sends them to other devices.

2. Mobile Phones
Many cell phone and smart phone providers offer voice
plans with Internet access. Mobile Internet connections
provide good speeds and allow you to access the Internet
on the go.
3. 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.

4. Broadband
This high-speed Internet connection is provided
through either cable or telephone companies. One
of the fastest options available, broadband
Internet uses multiple data channels to send large
quantities of information. The term broadband is
shorthand for broad bandwidth. Broadband
Internet connections such as DSL (Digital Subscriber
Line) and cable are considered high-bandwidth
connections.

11. Types of link to ISP
• Satellite
• In certain areas where broadband connection
is not yet offered, a satellite Internet option
may be available. Similar to wireless access,
satellite connection utilizes a modem.
