Cable broadband

Definition

Cable broadband is a high-speed internet connection that uses coaxial cable television infrastructure to deliver internet service to homes and businesses. This technology allows for faster download and upload speeds compared to traditional DSL and dial-up connections, making it a popular choice for many users. Cable broadband can provide multiple services, such as television and phone, all over the same connection, which enhances its value proposition.

5 Must Know Facts For Your Next Test

1. Cable broadband typically offers download speeds ranging from 25 Mbps to over 1 Gbps, making it significantly faster than many other types of internet connections.
2. The technology relies on the existing cable TV infrastructure, which allows providers to deliver internet service without needing to lay new lines.
3. Cable broadband often shares bandwidth among multiple users in a neighborhood, which can lead to slower speeds during peak usage times.
4. Some cable broadband providers also offer bundled services, combining internet with television and phone services for added convenience and cost savings.
5. In many areas, cable broadband competes directly with fiber-optic internet services, which can provide even higher speeds but may not be as widely available.

Review Questions

• How does cable broadband compare to other types of internet connections in terms of speed and infrastructure?
  • Cable broadband generally offers higher speeds than DSL and dial-up connections due to its use of coaxial cable infrastructure. It can provide fast download speeds, often ranging from 25 Mbps to over 1 Gbps, which makes it suitable for activities like streaming and gaming. In contrast, DSL connections depend on telephone lines, which typically offer slower speeds. Additionally, cable broadband utilizes the existing cable TV network, allowing for quicker deployment compared to new fiber-optic installations.
• What are some advantages and disadvantages of using cable broadband as an internet service option?
  • One major advantage of cable broadband is its high speed and reliability compared to traditional DSL or dial-up services. It also allows for bundling with television and phone services, providing greater convenience. However, a disadvantage is that bandwidth is shared among users in the same area, which can result in slower speeds during peak times when many people are online. This variability can be a concern for users who require consistent high-speed access.
• Evaluate the impact of competition between cable broadband and fiber-optic services on consumer choices and market dynamics.
  • The competition between cable broadband and fiber-optic services significantly affects consumer choices by driving innovation and price adjustments within the market. As fiber-optic providers often offer faster speeds with more stable connections, traditional cable providers may need to enhance their offerings or lower prices to retain customers. This dynamic encourages better service quality and options for consumers but can also lead to monopolistic practices in areas where one service is dominant. The ongoing competition shapes the landscape of broadband access policies by influencing regulatory considerations aimed at promoting fair competition and expanding access.
