Step-by-step explanation:
The student is asking to match each internet connection type with its corresponding property. Here are the correct matches:
A) Dial-up - Makes your phone line "busy"
B) DSL - Uses a higher frequency band than voice calls
C) Cable internet - Uses coaxial television cables
D) Mobile internet - Uses the cellular network
Here's how they work:
Dial-up internet operates by connecting a computer to the internet via a telephone line, which makes the line busy while using the internet.
DSL (Digital Subscriber Line) uses the existing telephone lines without blocking voice calls because it operates at a higher frequency.
Cable internet provides internet access through the coaxial cables that are also used to deliver cable television service.
Mobile internet leverages the same cellular networks that cell phones use to provide wireless internet access.
