  • 2. 

    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:

  • 3. 

    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.

    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.

    Rate this question:

  • 5. 

    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.

    Rate this question:

  • 6. 

    The term OSI stands for?

    • Operation Systems Internet

    • Open Systems Interconnection

    • Open Service Interconnection

    • Open Source Interconnection

    Correct Answer
    A. Open Systems Interconnection
    Explanation
    The term OSI stands for Open Systems Interconnection. This is a reference model that describes how different computer systems can communicate and exchange data with each other. It provides a framework for understanding and implementing network protocols, ensuring that different systems can work together effectively.

    Rate this question:

  • 7. 

    The IEEE is a professional organisation made up of engineers, scientists, researchers and students who have provided the standards in local and wireless networking. What does IEEE stand for?

    • Independent Electrical and Electronic Engineers

    • Institute of Energy and Economic Evaluation

    • Institute of Electrical and Electronic Engineers

    • Independent Organisation of Standardisation

    Correct Answer
    A. Institute of Electrical and Electronic Engineers
    Explanation
    The correct answer is "Institute of Electrical and Electronic Engineers." The IEEE is a professional organization that sets standards in various fields, including electrical and electronic engineering. It is made up of professionals and students in these fields and is known for its contributions to local and wireless networking standards.

    Rate this question:

  • 8. 

    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.

    Rate this question:

  • 9. 

    What PDU contains a source and destination address?

    • Bit

    • Frame

    • Segment

    • Packet

    Correct Answer
    A. Packet
    Explanation
    A packet contains the network address of the source and destination device.

    Rate this question:

  • 10. 

    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:

  • 11. 

    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.

    Rate this question:

  • 12. 

    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.
