Brief History – How Internet Connections Have Evolved

In the early days of the internet, options for accessing the online world were extremely limited. Most users connected via slow dial-up connections using analog phone lines and modems.

As technology advanced, new types of high-speed “broadband” internet connections emerged, including:

  • DSL: Uses copper phone lines to deliver faster speeds than dial-up.
  • Cable: Utilizes the same coaxial cables that deliver cable TV signals.
  • Fiber optic: Transmits data as light through flexible glass fibers offering unparalleled speeds.
  • Satellite: Leverages orbiting satellites to provide internet access virtually anywhere.

Wireless connectivity also expanded rapidly, with WiFi and mobile broadband giving users convenient untethered access:

  • WiFi: Allows devices to connect to the internet wirelessly over short distances.
  • Cellular mobile broadband: Uses cellular networks to deliver connectivity across wider areas.

Let’s explore each of the main connection types in more detail…


Dial-up connections use analog telephone lines to dial into an Internet Service Provider (ISP) to get online.

At speeds of just 56kbps, dial-up is extremely slow by today’s standards. However, it remains a cheap option for light internet users with no broadband availability.

How Dial-up Internet Works

Dial-up connections use telephone lines and modems to connect to the internet:

[Diagram showing dial-up connection process]
  1. A modem converts the digital data from your computer into analog signals for transmission over phone lines.
  2. Your modem dials and connects to your ISP’s modem bank.
  3. Analog signals are converted back into digital data for access to the internet.

With a dial-up connection, you cannot use your phone line for calls while online.


Maximum speeds reach 56kbps, but actual speeds often average around 40kbps. This makes simple web browsing possible but multimedia content frustrating.


  • Extremely cheap option available virtually everywhere
  • Modest speeds suffice for basic light usage


  • Very slow speeds by today’s standards
  • Ties up your phone line whenever online
  • Analog signals susceptible to line noise/interference

Examples of Dial-up Providers

Some ISPs still offer dial-up access, but most major broadband providers have phased it out. NetZero offers ad-supported free plans or paid plans starting at $9.95 per month.

Use Cases

Dial-up remains a viable option for extremely light internet users on a budget, such as:

  • Checking emails
  • Looking up information
  • Reading news/content

Multimedia activities will prove largely frustrating at typical dial-up speeds.


ISDN (Integrated Services Digital Network) represented an early evolution toward faster “broadband” internet connections. Offering speeds many times faster than dial-up internet, ISDN encodes data digitally for clearer and quicker transmission.

How ISDN Internet Works

ISDN connections work over digital telephone lines, structured into channels:

[Diagram showing ISDN connection utilizing channels over digital telephone line]

Most residential ISDN connections use Basic Rate Interface (BRI) comprising two 64kbps B-channels for data and one D-channel for control signals. This structure allows simultaneous use for internet access, telephone calls, and faxing.


Typical ISDN connection speeds include:

  • Basic Rate Interface (BRI) — 128kbps
  • Primary Rate Interface (PRI) — 1.5Mbps or higher

So substantially faster than dial-up internet.


  • Much faster speeds than standard dial-up
  • Ability to handle voice and data simultaneously
