Questions and Answers
  • 1. 

    Narrowband lines typically have transmission speeds less than _____.

    Explanation
    Narrowband lines typically have transmission speeds less than 56 kbps. This means that the data transfer rate for narrowband lines is slower than 56 kbps. Narrowband lines are commonly used for voice communication and low-speed data transmission, such as dial-up internet connections. The term "narrowband" refers to the limited bandwidth available for these types of lines, which restricts the amount of data that can be transmitted at any given time.

    Which protocol standard used for wired LAN connections specfies hardware characteristics, such as which wire carry which signals?

    Explanation
    Ethernet is the protocol standard used for wired LAN connections that specifies hardware characteristics, such as which wire carries which signals. Ethernet is a widely used technology for local area networks, allowing devices to communicate and share resources over a wired connection. It defines the physical and data link layer specifications, including the wiring scheme, signaling, and transmission speeds. Ethernet uses various standards, such as 10BASE-T, 100BASE-TX, and 1000BASE-T, to define the specific characteristics of the wired connections.

    Which of the following is a component of the user tier?

    Explanation
    The user tier in a web application architecture consists of the computers that have browsers that request and process web pages. These computers are responsible for interacting with the application interface and displaying the content to the users. They send requests to the server tier to retrieve data or perform actions, and then process the received responses to present the information in a user-friendly manner. The user tier plays a crucial role in enabling users to access and interact with the web application.

    What is an IP address?

    Explanation
    An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. This address serves two main functions: identifying the host or network interface and providing the location of the device in the network. By using IP addresses, devices can communicate with each other and transfer data across the internet.

    In the three-tier architecture arrangement, what is the second tier?

    Explanation
    The second tier in the three-tier architecture arrangement is the server tier. This tier is responsible for processing and managing the business logic of an application. It handles tasks such as data processing, application logic, and communication between the presentation tier and the data tier. The server tier acts as an intermediary between the client-side interface and the database, ensuring smooth and efficient operation of the application.

    When an individual uses the Internet, but not the Web, he or she is using ____.

    Explanation
    When an individual uses the Internet, but not the Web, he or she is using FTP. FTP stands for File Transfer Protocol, which is a standard network protocol used to transfer files between a client and a server on a computer network. Unlike the Web, which is a system of interconnected documents and resources accessed through the Internet, FTP specifically focuses on the transfer of files. Therefore, if someone is using the Internet for file transfer purposes, they are using FTP.

    .  The distinguishing characteristic of a LAN is______.

    Explanation
    A LAN (Local Area Network) is a network that connects devices within a limited area, such as a home, office, or building. The distinguishing characteristic of a LAN is that it connects at a single location, meaning that all devices within the network are physically connected to a central point, such as a router or switch. This allows for efficient and high-speed communication between devices within the LAN, facilitating file sharing, resource sharing, and collaboration among users.

    Which of the following is true of an ISP?

    Explanation
    An ISP, or Internet Service Provider, is a company that provides internet access to users. They serve as the connection between the user's device and the internet, acting as a gateway. The ISP provides the necessary infrastructure and services to enable users to access the internet, such as providing a modem or router, establishing the connection, and managing the network. Without an ISP, users would not be able to connect to the internet and access online services and websites.

    A(n) _____ s a set of rules that two communication devices follow.

    Explanation
    A protocol is a set of rules that two communication devices follow. These rules define the format, timing, sequencing, and error control of data transmission between devices. By adhering to the same protocol, devices can communicate effectively and ensure that data is transmitted accurately and efficiently.

    Each device on the LAN has a hardware component called the _____ that connects the device’s circuitry to the cable.

    Explanation
    The correct answer is NIC. A NIC (Network Interface Card) is a hardware component that connects a device's circuitry to the cable in a LAN (Local Area Network). It allows the device to send and receive data over the network by converting digital signals from the device into analog signals that can be transmitted over the cable, and vice versa. The NIC acts as the interface between the device and the network, enabling communication between them.

    Which of the following provides reliable Internet transport?

    Explanation
    TCP (Transmission Control Protocol) is a reliable internet transport protocol because it ensures that data packets are delivered accurately and in the correct order. It establishes a connection between the sender and receiver, performs error checking, and retransmits any lost or corrupted packets. TCP also implements flow control mechanisms to prevent congestion and ensure efficient data transfer. Overall, TCP provides a reliable and robust transport mechanism for internet communication.

    Which of the following is true of Web servers?

    Explanation
    Web servers are responsible for sending and receiving web pages to and from clients. When a client sends a request for a web page, the web server processes the request and sends the requested web page back to the client. This communication between the web server and the client allows users to access and view web pages on the internet. Therefore, the statement that web servers send and receive web pages to and from clients is true.
