what happens when two insulated wires are twisted around each other in a way that reduces and cancels out electromagnetic induction?

• they create a circuit that can transmit data.
• they block out all viruses and security breaches.
• they encourage crosstalk and unwanted signal transfer.
• they prevent designers and users from shielding their own wires from network interference.

simon connects to the internet using available telephone wires that do not have interruptions to service. what specific type of broadband connection does simon have?

• fiber optic
• satellite
• cable
• digital subscriber line (dsl)

Explanation:

For Question 9: Twisted pairs reduce electromagnetic induction (interference), enabling reliable data transmission. Other options are incorrect: they don’t block viruses, reduce crosstalk (opposite), and don’t prevent shielding.
For Question 10: DSL uses existing telephone wires for broadband without service interruptions. Fiber uses cables, satellite uses signals, cable uses coaxial—only DSL matches telephone wires.

Answer:

Question 9: A. They create a circuit that can transmit data
Question 10: D. digital subscriber line (DSL)
