Computer And Media Studies: Quiz 3 - Quiz


This quiz covers the networks, internet, internet safety and operating systems lectures from the past two weeks.


Questions and Answers
  • 1. 

    What piece of hardware allows a computer to communicate on a network?

    • A.

      BIOSs

    • B.

      Applications

    • C.

      Operating Systems

    • D.

      A network card

    Correct Answer
    D. A network card
    Explanation
    A network card, also known as a network interface card (NIC), is a piece of hardware that enables a computer to communicate on a network. It is responsible for connecting the computer to the network, allowing it to send and receive data. Without a network card, a computer would not be able to access or interact with other devices on the network.

    Why is Hypertext Transfer Protocol important?

    • A.

      Without it there wouldn’t be any standard way to transfer data on the internet.

    • B.

      It was written by Bill Gates and thus is worth a lot of money.

    • C.

      It is a very important piece of computer hardware that is in charge of booting the BIOS.

    • D.

      All of the above.

    Correct Answer
    A. Without it there wouldn’t be any standard way to transfer data on the internet.
    Explanation
    Hypertext Transfer Protocol (HTTP) is a protocol that allows the transfer of data on the internet. It provides a standard way for web browsers and servers to communicate and exchange information. Without HTTP, there would be no standardized method for transferring data, which would hinder the functioning of the internet as we know it. The other options provided in the question are incorrect and do not accurately describe the importance of HTTP.

    What does LAN stand for?

    • A.

      Learn About Nematodes

    • B.

      Large Actual Numbers

    • C.

      Local Area Network

    • D.

      Large Amphitheater Network

    Correct Answer
    C. Local Area Network
    Explanation
    LAN stands for Local Area Network, which is a network that connects computers and devices within a limited area such as a home, office, or building. It allows for the sharing of resources, such as files and printers, and enables communication between devices within the network. "Learn About Nematodes," "Large Actual Numbers," and "Large Amphitheater Network" are not relevant and do not represent the correct meaning of LAN.

  • 6. 

    Servers turn on and off all the time.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement "Servers turn on and off all the time" is false. Servers are typically designed to run continuously without frequent shutdowns. They are built to handle high workloads and provide uninterrupted services. Turning servers on and off frequently can disrupt operations and cause downtime. Therefore, it is not common for servers to be regularly powered on and off.

    The internet has been around since the early 1900’s.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because the internet was not around in the early 1900s. The internet as we know it today was developed in the late 1960s and early 1970s. It was initially used by the military and research institutions and was not widely accessible to the public until the 1990s. Therefore, the internet has not been around since the early 1900s.

    WAN stands for Wide Area Network.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because WAN stands for Wide Area Network. A WAN is a network that covers a large geographical area, typically connecting multiple local area networks (LANs) together. It allows for the transmission of data, voice, and video across long distances, often using public or private telecommunications infrastructure.

      A computer network covering a small physical area

    Correct Answer
    D. A computer network covering a small physical area
    Explanation
    A LAN, or Local Area Network, is a computer network that covers a small physical area, such as a home, office, or school. It allows computers and devices within this area to communicate and share resources, such as files and printers. Unlike wide area networks (WANs) that cover larger geographic areas, LANs are typically confined to a single building or campus. LANs are commonly used in homes and businesses to connect computers, servers, and other devices together for efficient communication and data sharing.
