D413 - Telecommunications and Wireless Communications Exam
Questions and Answers | 2026 Update | 100% Correct.
1. Network: Interconnected collection of computers and communication devices
2. Node: Individual computer or device connected to a network
3. Host: Computer or device connected to a network that provides services
4. Advantages of Networking: Sharing equipment and data
5. Disadvantages of Networking: Personnel and cost increase, vulnerabilities to cyberattacks
6. Local Area Network (LAN): A network that is usually confined to a single building and managed by a single entity. Example:
Oflce Building
7. Metropolitan Area Network (MAN): Consists of two or more LANs connected with private or public communication lined
within the same geographic area—for example, a computer network used by governmental employees of an entire city.
8. Wide Area Network (WAN): Consists of a large number of networks and PCs connected with private and public
communication lines throughout many geographic areas; for example, computers used by the US government.
9. Personal Area Network (PAN): A small network, perhaps consisting of a single computer and mobile device.
10. Campus Area Network (CAN): A network spread across multiple buildings in the same geographical location, much like a
college campus.
11. Global Area Network (GAN): Any network that spans multiple countries, for example, the Internet.
12. Star Topology: A topology that involves running cables from each node to connect a single point. The center is usually a
device known as a hub.
13. Ring Topology: Common network topology with devices connected in a circular loop
14. Bus Topology: Network topology that uses a single cable or conductor to connect all nodes on the network.
15. Mesh Topology: A network topology where each node is connected to each of the other nodes. The number of cable paths
rapidly increases as more nodes are added.
, 16. Centralized Administration: Methodology used to administer a client/server network
17. Decentralized Administration: Methodology used to administer a peer-to-peer network
18. Cloud Computing: Otters services including SaaS, PaaS, and IaaS
19. Private Cloud: Type of cloud that is not accessible to the general public
20. Public Cloud: Type of cloud that is accessible to the general public
21. Hybrid Cloud: Type of cloud that combines private and public cloud services
22. Network Operating System (NOS): Provides a communication system between nodes. Examples include Windows Server
2008/2012/2016, Unix, and Linux.
23. Data Segments: Divided parts of data to be transmitted on a network
