    Correct Answer
    A. Kernel
    Explanation
    The kernel is the component of the UNIX operating system that interacts directly with the system hardware. It is responsible for managing resources, such as memory and CPU, and provides an interface for other software components to access these resources. The kernel also handles device drivers, which allow the operating system to communicate with hardware devices. Therefore, the kernel plays a crucial role in facilitating the interaction between the operating system and the system hardware.

    Which interrupt request (IRQ) line number is normally used for the floppy disk controller?

    • 2

    • 4

    • 6

    • 8

    Correct Answer
    A. 6
    Explanation
    The floppy disk controller typically uses IRQ line number 6. IRQ stands for Interrupt Request, and it is a mechanism used by devices to request the attention of the CPU. Each device is assigned a specific IRQ line number, and in the case of the floppy disk controller, it is usually assigned to IRQ 6. This allows the controller to interrupt the CPU when it needs to transfer data to or from the floppy disk.

    Which is not a characteristic of high-order languages?

    • They are nearly self-documenting

    • They use English-like statements

    • Source codes that are written closest to machine language

    • Programs are transportable between computers with few changes

    Correct Answer
    A. Source codes that are written closest to machine language
    Explanation
    The characteristic of high-order languages is that they are not written closest to machine language. High-order languages are designed to be more user-friendly and abstract away the complexities of machine language. They use English-like statements and are nearly self-documenting, making them easier to read and understand. Additionally, programs written in high-order languages are portable between different computers with minimal changes, further highlighting their user-friendly nature.

    What best describes programming machine code?

    • Another term for firmware

    • Statements that correspond to complex actions

    • Instructions in a form that is acceptable to the computer

    • Source code that, when compiled, is appropriate for the computer

    Correct Answer
    A. Instructions in a form that is acceptable to the computer
    Explanation
    Programming machine code refers to the set of instructions that are written in a form that the computer can understand and execute. These instructions are in a low-level language that directly communicates with the computer's hardware. It is different from source code, which needs to be compiled before it can be executed. Machine code is the most basic level of programming and is often used to control the behavior of computer hardware.

    Which protocol is commonly used for managing the security of a message transmission on the internet?

    • Secure socket layer (SSL)

    • Public Key infrastructure (PKI)

    • Data encryption standard (DES)

    • Transport layer security (TLS)

    Correct Answer
    A. Secure socket layer (SSL)
    Explanation
    The correct answer is Secure Socket Layer (SSL). SSL is commonly used for managing the security of a message transmission on the internet. It provides encryption and authentication to ensure that the data being transmitted between a client and a server is secure and cannot be intercepted or tampered with by unauthorized parties. SSL establishes a secure connection between the client and the server, encrypting the data that is being transmitted, and verifying the identity of the server to ensure that it is trusted. SSL has been widely adopted and is used for secure communication in various applications, including websites, email, and online banking.

    What kind of server contains the master listing of all active directory objects in the forest?

    • Dynamic host configuration protocol (DHCP)

    • Domain controller

    • Global catalog

    • Member

    Correct Answer
    A. Global catalog
    Explanation
    The global catalog is a type of server that contains the master listing of all active directory objects in the forest. It stores a partial replica of all objects in the forest, making it easier and faster to search for and locate objects across different domains. This allows users to access resources and services in the network efficiently. The global catalog is essential for functions such as authentication, user and group membership lookups, and directory searches in a multi-domain environment.

    What defines the rules by which operations can be performed on a particular resource?

    • Rights

    • Permissions

    • Access control lists

    • Hardware configuration

    Correct Answer
    A. Permissions
    Explanation
    Permissions define the rules by which operations can be performed on a particular resource. They determine what actions a user or group can take on a resource, such as read, write, execute, or delete. Permissions are typically set by the system administrator or owner of the resource and help to ensure that only authorized individuals can access or modify it. Access control lists and rights are related concepts that can also play a role in defining these rules, but the most direct and specific term for this is permissions. Hardware configuration, on the other hand, refers to the physical setup and settings of computer hardware and is not directly related to defining rules for resource operations.
