Network Standards/Protocols: OSI Quiz

2.

How many layers does the OSI model contain?

4
5
6
7

Correct Answer

A. 7

Explanation

The OSI model is a conceptual framework that standardizes the functions of a communication system into seven different layers. Each layer has a specific set of tasks and responsibilities, which collectively ensure the efficient transmission of data between devices. These layers include the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer. Therefore, the correct answer is 7.

3.

Network standards are the ________ that companies should follow when designing and manufacturing their equipment.

Correct Answer
guidelines

Explanation
Network standards are a set of established principles and protocols that serve as guidelines for companies when designing and manufacturing their equipment. These standards ensure compatibility, interoperability, and reliability across different network devices and systems. By adhering to these guidelines, companies can ensure that their equipment meets industry specifications and can seamlessly integrate with other network components. Following network standards also promotes consistency and uniformity in network infrastructure, making it easier to troubleshoot and maintain network functionality.

Network protocols are the common that computers use to with each other.

Correct Answer
language
communicate

Explanation
Network protocols are the common means that computers use to communicate with each other. These protocols serve as a set of rules and guidelines that allow different devices and systems to understand and exchange data effectively. By using a standardized language, computers can establish connections, transmit information, and ensure that data is received and interpreted correctly across the network.

5.

Layer 1 of the OSI model is the network layer?

True
False

Correct Answer

A. False

Explanation

Layer 1 of the OSI model is the physical layer

Rate this question:

6.

The physical layer of the OSI model is concerned primarily with transmitting?

Packets
Segments
Frames
Data bits (zeros or ones)

Correct Answer

A. Data bits (zeros or ones)

Explanation

The physical layer of the OSI model is responsible for transmitting data bits (zeros or ones) over the network. It deals with the actual physical transmission of data through the use of cables, connectors, and other hardware components. This layer is concerned with the electrical, mechanical, and functional aspects of the network, ensuring that the data is transmitted accurately and reliably.

7.

What layer of the ISO model works with routers?

Network layer
Presentation
Transport
Data Link

Correct Answer

A. Network layer

Explanation

The network layer of the ISO model works with routers. This layer is responsible for routing packets across different networks, determining the best path for data transmission, and addressing and forwarding data packets. Routers operate at this layer by examining the destination IP address in the packet header and making decisions on how to forward the packet to its destination. Therefore, the network layer is the correct answer for this question.

8.

Which layer of the OSI model works with cables, connectors, NIC's and HUB's?

Data Link Layer
Application Layer
Physical Layer
Presentation Layer

Correct Answer

A. Physical Layer

Explanation

The Physical Layer of the OSI model is responsible for the physical transmission of data over the network. It deals with the actual hardware components such as cables, connectors, network interface cards (NICs), and hubs. This layer ensures that the data is transmitted reliably and efficiently through the physical medium, such as copper or fiber optic cables. It defines the electrical, mechanical, and procedural characteristics of the physical connection between devices.

9.

The Application Layer performs error detection and correction?

True
False

Correct Answer

A. False

Explanation

The Data Link Layer performs error detection and correction and marks where a message starts and where it ends.

1

10.

Which layer is concerned with formatting and editing user inputs and outputs?

Application Layer
Presentation Layer
Network Layer
Physical Layer

Correct Answer

A. Presentation Layer

Explanation

The Presentation Layer is concerned with formatting and editing user inputs and outputs. This layer is responsible for translating data into a format that can be understood by the receiving application. It handles tasks such as data encryption, compression, and decompression. By formatting and editing user inputs and outputs, the Presentation Layer ensures that the data is presented in a consistent and standardized manner, regardless of the differences in the systems and devices involved in the communication process.

Rate this question:

11.

Which layer provides an interface to software that enables it to use network services such as file transfers, email and web services?

Presentation Layer
Network Layer
Data Link Layer
Application Layer

Correct Answer

A. Application Layer

Explanation

The Application Layer provides an interface to software that enables it to use network services such as file transfers, email, and web services. This layer is responsible for managing communication between applications and the network, allowing applications to access and utilize network services efficiently. It provides services and protocols that allow different applications to communicate with each other over a network, making it the correct answer in this context.

Rate this question:

12.

Which layer manages the diaglogue between applications on two different computers?

Session Layer
Physical Layer
Data Link Layer
Presentation Layer

Correct Answer

A. Session Layer

Explanation

The session layer is responsible for managing the dialogue between applications on two different computers. It establishes, maintains, and terminates connections between the communicating devices, ensuring that the data is properly synchronized and delivered in the correct order. This layer also handles session checkpointing and recovery, allowing for the resumption of interrupted sessions.
