Answer 4

client-to-server

Question 5

Answer 8

LAN

Question 9

What organization is responsible for developing standards for fiber optic, bluetooth, 802.11 and 802.3?

Answer 9

IEEE

Question 10

networks that are designed to connect similar computers that share data and software with each other are called:

Answer 10

peer-to-peer networks

Question 11

In order to connect these networks together, you need to select a topology that allows you to send confidential information the fastest, and does not allow adversaries to inject themselves in your topology as a new “legitimate” node to pass traffic through.

Which topology discussed in todays lesson is the best for this goal?

Answer 11

point-to-point

Question 12

What type of cable connection, discussed today, is most desirable for transmissions that exceed 400m and require large data throughput?

Answer 12

fiber

Question 13

Which topology does not have a network outage if a singular node goes out, but DOES have a single point of failure within its centralized network management?

Answer 13

star

Question 14

Which IT Infrastructure does the DOD use to globally interconnect information?

Answer 14

DODIN

Question 15

Which topology can be identified by the following characteristic:

A terminator at each end, that dissipates signal to reduce collisions?

Answer 15

bus

Question 16

Which topology is the most flexible to build and requires knowledge of how various topologies can communicate with each other?

Answer 16

hybrid

Question 17

Which type of network is preferrable if your environment has and/or needs the following attributes:
- Very small geographic location
- Ability for users to roam and stay connected
- Both wired and wireless technologies (Ethernet, Wi-Fi, etc)
- Service to individuals and their personal devices (laptop, printer, smart tv, and tablet)

Answer 17

PAN

Question 18

What is the purpose of a standard?

Answer 18
