○ modulation
○ optical recognition
○ demodulation
○ virtualization

1. a(n) ____ is a private network that connects more than one organization.

○ intranet
○ extranet

1. ____ describes how a network is arranged and how resources are coordinated and shared.

○ proxy structure
○ node topology
○ network architecture
○ base strategy

Explanation:

For question 7, the process of converting from analog to digital is called digitization and none of the given options are correct. But modulation changes the characteristics of a carrier signal based on the input signal (can be analog - to - digital conversion in some cases), optical recognition is about identifying optical data, demodulation is the reverse of modulation, and virtualization is about creating virtual resources.
For question 8, an extranet is a private network that connects more than one organization. An intranet is internal to an organization, the internet is a public network, and Ethernet is a local - area network technology.
For question 9, network architecture describes how a network is arranged and how resources are coordinated and shared. A proxy structure is related to proxy servers, node topology is about the layout of nodes, and base strategy is not the correct term for this concept.

Answer:

1. None of the above
2. B. extranet
3. C. Network architecture
