25
What is a P2P network model?
A decentralized network composed of interconnected nodes that communicate and share resources directly.
26
What are the advantages of a P2P network?
Easy to set up Does not require a network operating system Self-organizing
27
What is a Virtual Private Network (VPN)?
A VPN establishes a digital connection between your computer and a remote server owned by a VPN provider.
28
What is the purpose of a VPN?
To encrypt personal data, mask IP address, and ensure online experiences are private and secure.
29
What does LAN topology refer to?
The physical and logical arrangement of the interconnected devices within a local network.
30
Name some common LAN topologies.
* Bus * Star * Ring * Mesh * Hybrid * Tree
31
What is Bus Topology?
All devices are connected to a single cable or backbone for communication.
32
What is an advantage of Bus Topology?
It is simple and inexpensive.
33
What is a disadvantage of Bus Topology?
The entire network shuts down if there is a break in the main wire.
34
What characterizes Star Topology?
All devices are connected directly to a central hub or switch.
35
What is a disadvantage of Star Topology?
If the central hub fails, the entire network becomes unusable.
36
What is Ring Topology?
Devices are connected in a circular fashion, forming a continuous loop.
37
What is a disadvantage of Ring Topology?
If a single device or connection in the ring fails, the entire network can be disrupted.
38
What is Tree Topology?
Devices are connected in a hierarchical structure, resembling the shape of a tree.
39
What is a disadvantage of Tree Topology?
If the root fails, the entire network will fail.
40
What is Mesh Topology?
Each node is connected to one or more other nodes, creating a multi-path network.
41
What is an advantage of Mesh Topology?
Multiple redundant paths provide alternative routes in case of node or connection failures.
42
What is Hybrid Topology?
A network topology that combines two or more different network topologies.
43
What is a disadvantage of Hybrid Topology?
It can be high cost and complex.
44
What is Hybrid Topology?
A network topology that combines two or more different network topologies to leverage the advantages of each. ## Footnote Advantages include flexibility, scalability, and easier management for large networks. Disadvantages include high cost and complexity.
45
What are Network Protocols?
A set of rules outlining how connected devices communicate across a network to exchange information easily and safely. ## Footnote Divided into three groups: Network Communication Protocols, Network Security Protocols, and Network Management Protocols.
46
What is the OSI Model?
A 7-layer model that describes how different layers of a communication system should interact with each other. ## Footnote The seven layers are: Application, Presentation, Session, Transport, Network, Data-link, and Physical.
47
What is the responsibility of the Transport Layer?
Process to process delivery and ensures reliable transfer of data between users. ## Footnote It is one of the layers in the OSI model.
48
Fill in the blank: The _______ layer is responsible for host to host delivery.
Network Layer
49
What is encapsulation in network protocols?
The process of wrapping data with protocol information at each layer of the OSI model. ## Footnote Each layer adds its own header, creating segments, packets, and frames.
50
True or False: Packet switching provides a direct connection between devices.
False
51
What are the two leading technologies used in switched networks?
Circuit switching and packet switching. ## Footnote Circuit switching is used in traditional telephone networks, while packet switching is used for computer communication.
52
What is the main advantage of packet switching over circuit switching?
More efficient and less expensive. ## Footnote Packet switching divides messages into packets, which can take different paths to the destination.
53
What does the Transmission Control Protocol (TCP) do?
Defines how Internet-connected computers can exchange, control, and confirm messages.
54
What is a Virtual Private Network (VPN)?
Creates a secure private network connection between your computer and the organization. ## Footnote It is commonly used for secure communication over the internet.
55
What are LAN protocols?
A collection of networking standards that cover the physical and data link layer specifications for technologies such as Ethernet and Wi-Fi.
56
What are the operating frequencies of Wi-Fi?
5.0 GHz and 2.4 GHz. ## Footnote A 6 GHz frequency is expected to be introduced soon.
57
What is the primary function of a firewall?
Controls access to a network and protects against external threats.
58
What is the difference between wired and wireless home networks?
Wired networks use Ethernet connections while wireless networks use Wi-Fi and radio signals. ## Footnote Wireless networks require a wireless adapter or router.
59
What is the role of an Intrusion Detection System (IDS)?
Works with the firewall to analyze all incoming and outgoing network traffic for security.
60
Fill in the blank: _______ is the most-used LAN protocol.
Ethernet
