Learning Objectives

By the end of this chapter, you will be able to:

  • Describe the role of an Internet Service Provider (ISP).
  • Differentiate between wired and wireless internet connections.
  • Identify common types of broadband connections.

Connecting to the Internet

To connect to the internet, you need a connection from an Internet Service Provider (ISP). An ISP is a company that provides access to the internet. The connection from your home or business to the ISP is often called the “last mile.”

There are two main categories of internet connections:

1. Wired Connections (Broadband)

Broadband refers to high-speed internet access. Common types of wired broadband connections include:

  • Cable: Uses the same coaxial cable network as cable television to provide internet access.
  • DSL (Digital Subscriber Line): Uses existing telephone lines to provide internet access.
  • Fiber Optic: The fastest type of broadband, which uses light to transmit data through fiber optic cables.

2. Wireless Connections

  • Wi-Fi: Allows you to connect to the internet wirelessly within a limited area, using a router that is connected to a wired broadband service.
  • Cellular Data: Allows you to connect to the internet from a mobile device using your cellular provider’s network (e.g., 4G, 5G).
  • Satellite: Provides internet access via communication satellites, often used in rural or remote areas where wired broadband is not available.

Summary

Connecting to the internet requires a service from an ISP. This connection can be wired, using broadband technologies like cable, DSL, or super-fast fiber optics, or it can be wireless, using Wi-Fi for local access and cellular or satellite for mobile or remote access. Most users today use a combination of these technologies to stay connected.

Key Takeaways

  • An ISP provides access to the internet.
  • Wired broadband connections include cable, DSL, and fiber.
  • Wireless connections include Wi-Fi, cellular, and satellite.
  • Fiber is the fastest type of wired broadband connection.
