    ____ are commonly hybrid networks. Often connect multiple network structures to create one large network.

    • WMAN

    • MAN

    • WAN

    • LAN

    Correct Answer
    A. WAN
    Explanation
    WAN (Wide Area Network) is the correct answer because it commonly consists of hybrid networks that connect multiple network structures to create one large network. WANs are designed to cover a wide geographical area and connect different locations, such as offices, buildings, or cities, allowing for communication and data transfer between them. This makes WANs suitable for organizations that have branches or offices in different locations and need to establish a unified network infrastructure.

    A high-speed network that can carry voice, data, and images at up to 200 Mbps or faster over distances of up to 75 km. Based on the network architecture, the transmission speed can be higher for short distances.

    • LAN

    • MAN

    • WAN

    • WMAN

    Correct Answer
    A. MAN
    Explanation
    MAN stands for Metropolitan Area Network, which is a high-speed network that can carry voice, data, and images at up to 200 Mbps or faster over distances of up to 75 km. It is designed to cover a larger geographical area than a LAN (Local Area Network) but smaller than a WAN (Wide Area Network). MANs are typically used to connect multiple LANs within a city or metropolitan area.

    A network connection device similar to a bridge except that is usually visible to the user.  It translates data between one type of network and another.

    • Bridge Routers

    • Gateways

    • Modems

    • Cables

    Correct Answer
    A. Gateways
    Explanation
    A gateway is a network connection device that is similar to a bridge but is usually visible to the user. It translates data between one type of network and another. Gateways are often used to connect networks with different protocols or technologies, allowing them to communicate with each other. Unlike bridges, which only connect networks of the same type, gateways can facilitate communication between different types of networks.

    A protocol that is used to break apart and rebuild information that travels over the internet.

    • TCP

    • HTTP

    • FTP

    • UDP

    Correct Answer
    A. TCP
    Explanation
    TCP (Transmission Control Protocol) is a protocol used to break apart and rebuild information that travels over the internet. It provides reliable, ordered, and error-checked delivery of data packets between devices. TCP ensures that data packets are transmitted in the correct order and that any lost or corrupted packets are retransmitted. It also manages the flow of data between devices to prevent congestion and ensure efficient transmission. TCP is widely used for applications such as web browsing, email, and file transfer, where reliable and accurate data transmission is crucial.

    ______ is used by a router to exchange the information with other routers.

    • UDP

    • ICMP

    • SMTP

    • SNMP

    Correct Answer
    A. ICMP
    Explanation
    ICMP (Internet Control Message Protocol) is used by a router to exchange information with other routers. ICMP is a network protocol that allows routers to send error messages and operational information to other routers or hosts in the network. It is commonly used for diagnostic and troubleshooting purposes, such as reporting errors, checking network connectivity, and determining the best path for data packets. Unlike UDP (User Datagram Protocol), SMTP (Simple Mail Transfer Protocol), and SNMP (Simple Network Management Protocol), ICMP is specifically designed for communication between routers and does not handle data transfer or email transmission.

    Bandwidth refers to the speed at which information can transfer and the amount of information that can transfer immediately. As the bandwidth increases, the network becomes more complex.

    • Size of network

    • Cost

    • Transfer of information

    • Compatibility

    Correct Answer
    A. Transfer of information
    Explanation
    The correct answer is "Transfer of information". Bandwidth refers to the speed at which information can be transferred and the amount of information that can be transferred immediately. Therefore, increasing the bandwidth allows for faster and more efficient transfer of information within a network.
