Networking Fundamentals Assessment

What are the three main types of networks?

• Virtual Area Network (VAN)

• Local Area Network (LAN), Wide Area Network (WAN), Metropolitan Area Network (MAN)

• Global Area Network (GAN)

• Personal Area Network (PAN)

Define a Local Area Network (LAN).

• A Local Area Network (LAN) is a type of network that only connects wireless devices.

• A Local Area Network (LAN) is a network that connects devices over the internet.

• A Local Area Network (LAN) is a network that connects devices across multiple cities.

• A Local Area Network (LAN) is a network that connects devices within a small geographic area.

What is the primary purpose of a Wide Area Network (WAN)?

• To enhance the performance of a local network.

• To connect multiple LANs over large distances.

• To provide internet access to a single device.

• To connect devices within a single building.

List the layers of the OSI model from top to bottom.

• Application, Transport, Network, Data Link, Session, Presentation, Physical

• Physical, Data Link, Network, Transport, Session, Application, Presentation

• Session, Application, Presentation, Physical, Data Link, Transport, Network

• Application, Presentation, Session, Transport, Network, Data Link, Physical

What is the function of the Transport layer in the OSI model?

• The Transport layer handles physical connections between devices.

• The Transport layer manages end-to-end communication, error recovery, and flow control.

• The Transport layer is responsible for data encryption and decryption.

• The Transport layer manages the routing of packets across networks.

Describe the TCP/IP model and its significance.

• The TCP/IP model is a five-layer framework used exclusively for email transmission.

• The TCP/IP model has three layers that focus on hardware communication.

• The TCP/IP model is only relevant for local networks and not the internet.

• The TCP/IP model is a four-layer framework for network communication, crucial for internet functionality and interoperability.

What is data encapsulation in networking?

• Data encapsulation is the method of securing data against unauthorized access.

• Data encapsulation refers to the physical transmission of data over a network.

• Data encapsulation is the process of wrapping data with protocol information at each layer of the OSI model.

• Data encapsulation is the process of compressing data for storage.

which one is faster ?

• TCP

• UDP

What are the key characteristics of the UDP protocol?

• Key characteristics of UDP include connectionless communication, low latency, minimal overhead, and lack of delivery guarantees.

• Connection-oriented communication

• High latency

• Guaranteed delivery of packets

Name some common uses of computer networks in everyday life.

• Common uses of computer networks include internet access, email communication, media streaming, online shopping, and social networking.

• Playing video games offline

• Using a typewriter for documents

• Sending letters through postal mail
