  • 2. 

    On the osi model what is level 4?

    • Transport layer

    Correct Answer
    A. Transport layer
    Explanation
    The correct answer is the transport layer. The OSI model is a conceptual framework that defines the functions of a communication system. It is divided into seven layers, with each layer responsible for a specific set of tasks. The transport layer, which is level 4 of the OSI model, handles the reliable delivery of data between two endpoints. It ensures that data packets are delivered in the correct order and without errors. This layer also provides mechanisms for flow control and error recovery, making it essential for establishing a reliable communication channel.

    On the osi model what is level 5?

    • Session layer

    Correct Answer
    A. Session layer
    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 role and interacts with the layers above and below it. Level 5 in the OSI model is the session layer. This layer is responsible for establishing, managing, and terminating sessions between applications. It ensures that data is transferred smoothly and error-free by handling synchronization, checkpointing, and recovery of data exchange. The session layer also manages security and authentication processes during communication sessions.

  • 4. 

    On the osi model what is level 2?

    • Data link layer

    Correct Answer
    A. Data link layer
    Explanation
    The correct answer is the data link layer. In the OSI model, level 2 is known as the data link layer. This layer is responsible for the reliable transmission of data between two nodes on a network. It handles error detection and correction, as well as the formatting and organization of data into frames for transmission. The data link layer also manages access to the physical network medium and controls how data is sent and received over the network.

    Rate this question:

  • 5. 

    On the osi model what is level 1?

    • Physical layer

    Correct Answer
    A. Physical layer
    Explanation
    The correct answer is physical layer. In the OSI model, the physical layer is the lowest level and is responsible for the actual transmission of data bits over a physical medium. It deals with the electrical, mechanical, and procedural aspects of the physical connection between devices. This layer defines the physical characteristics of the network such as cables, connectors, and signaling. It ensures that data is transmitted reliably and accurately across the network.

    Rate this question:

  • 6. 

    What hardware devices does the transport layer deal with?

    • Gateway

    Correct Answer
    A. Gateway
    Explanation
    The transport layer of the network protocol stack is responsible for managing the end-to-end communication between two devices. It ensures reliable and efficient data transfer by breaking the data into smaller segments and reassembling them at the receiving end. A gateway is a hardware device that acts as an interface between different networks. It can connect networks with different protocols or architectures, allowing data to flow between them. Therefore, the transport layer may interact with gateways to facilitate communication between devices on different networks.

  • 7. 

    What is IRQ 3 used for?

    • Com2 or com4

    Correct Answer
    A. Com2 or com4
    Explanation
    IRQ 3 is used for the communication ports COM2 or COM4. These ports are commonly used for serial communication in computer systems. IRQ (Interrupt Request) is a signal that allows devices to request attention from the CPU. In this case, IRQ 3 is specifically assigned to handle communication for COM2 or COM4 ports, which are used for connecting external devices such as modems, printers, or serial mice to the computer.

    Rate this question:

  • 8. 

    What is IRQ 13 used for?

    • Math co processor

    Correct Answer

    Rate this question:

  • 9. 

    What is IRQ 6 used for?

    • Floppy disk controller

    Correct Answer
    A. Floppy disk controller
    Explanation
    IRQ 6 is used for the floppy disk controller. This means that when a device connected to the floppy disk controller requires attention or wants to communicate with the computer's CPU, it will send an interrupt signal on IRQ 6. This allows the CPU to prioritize and handle the request from the floppy disk controller in a timely manner.
