Which of the following groups correctly identifies examples of broadband Internet connection technologies?

Introduction / Context:
Broadband Internet access refers to high-speed, always-on connections that provide much higher data rates than traditional dial-up. There are several physical and wireless technologies that can deliver broadband service to homes and businesses. This question asks you to identify which option lists actual connection technologies associated with broadband Internet.

Given Data / Assumptions:

• Broadband technologies include wired and wireless access methods.
• Examples are DSL, cable, fiber-to-the-premises, Wi-Fi hotspots, and fixed wireless links.
• Some acronyms in the options refer to protocols or generic terms rather than access technologies.
• We want the option that lists only connection technologies, not protocols or generic identifiers.

Concept / Approach:
Digital Subscriber Line (DSL) uses telephone lines for broadband. Wi-Fi is a wireless LAN technology that can provide broadband connectivity within its coverage area. Fixed wireless refers to point-to-point or point-to-multipoint radio links that deliver broadband access without wired last-mile connections. By contrast, IP (Internet Protocol) is a network-layer protocol, FTP is a file transfer protocol, and OSP is not a standard access technology acronym in this context. The correct option must list technologies used to provide broadband access, not protocols used on top of those connections.

Step-by-Step Solution:
1. Examine Option A: DSL, Wi-Fi, and fixed wireless are all recognized methods of delivering broadband Internet.2. Examine Option B: IP is a protocol, not a specific connection technology, and FTTP is fiber-to-the-premises, which is broadband, but the set mixes protocol and technology inconsistently.3. Examine Option C: FTP is an application-layer file transfer protocol, OSP is not a standard broadband technology term here, and IP is a protocol, not an access method.4. Examine Option D: OSP and FTP again are not access technologies, and while cellular networks can provide broadband, the grouping is still incorrect and mixes protocols with access.5. Option A is the only option that cleanly lists three access technologies that are commonly used for broadband Internet connections.6. Therefore, Option A is correct.

Verification / Alternative check:
Telecommunication providers commonly advertise DSL, Wi-Fi hotspots, and fixed wireless services as forms of broadband access. Documentation from ISPs and standards bodies classifies these as broadband technologies. By contrast, IP and FTP are listed among network and application protocols in reference material, not as access technologies, confirming that they should not be grouped as broadband connection types.

Why Other Options Are Wrong:
Option B is wrong because IP is a protocol that runs over many different access technologies; it is not itself a physical or radio access type.Option C is wrong because FTP and IP are protocols; none of the three entries is purely an access technology.Option D is wrong because it combines a vague abbreviation, a protocol, and a generic network type without clearly listing common broadband technologies.

Common Pitfalls:
Students often confuse protocols (like IP and FTP) with access technologies because both are related to getting data onto the Internet. Remember that broadband connection types refer to how your device physically or wirelessly connects to a provider's network, while protocols describe how data is formatted and transmitted over those connections. Recognising this distinction will help you quickly identify the correct group of broadband technologies in similar questions.

Final Answer:
DSL, Wi-Fi, fixed wireless
