    A tool used to secure a crimp onto the end of a cable is a _________.

    Explanation
    A crimper is a tool specifically designed to secure a crimp onto the end of a cable. It is used to create a secure and reliable connection by compressing the crimp onto the cable, ensuring that it does not come loose or disconnect. This tool is commonly used in electrical and telecommunications installations to terminate cables and ensure proper connectivity.

    With 10BaseT, the maximum distance between the hub and the node is ____ meters

    Explanation
    With 10BaseT, the maximum distance between the hub and the node is 100 meters. This is because 10BaseT is an Ethernet standard that uses twisted pair cables for communication. The "10" in 10BaseT refers to the maximum data transfer rate of 10 Mbps, while "Base" indicates baseband transmission. The "T" stands for twisted pair, which is the type of cable used. Twisted pair cables have a maximum length limitation due to signal degradation, and in the case of 10BaseT, the maximum distance is 100 meters.

    A properly running average Ethernet has up to _____ percent collisions.

    Explanation
    A properly running average Ethernet has up to 10 percent collisions. This means that out of all the packets being sent on the Ethernet network, only 10 percent of them collide with other packets. Collisions occur when two or more devices try to transmit data at the same time, causing the data to become corrupted. A lower collision rate indicates a more efficient and reliable network.

    What company originally developed Ethernet in 1993?

    Explanation
    Xerox is the correct answer because they originally developed Ethernet in 1973. Ethernet is a widely used networking technology that allows computers and devices to connect and communicate with each other on a local area network (LAN). Xerox's development of Ethernet revolutionized computer networking and paved the way for the internet as we know it today.

    Data that is broken down into smaller pieces which are transmitted between computers is know as what?

    Explanation
    Data that is broken down into smaller pieces and transmitted between computers is known as frames. Frames are used in networking to efficiently transmit data over a network. Each frame contains a portion of the original data along with additional information such as source and destination addresses. These smaller pieces allow for more efficient transmission and can be reassembled at the receiving end to reconstruct the original data.

    A method of connecting hubs that reverses the sending and receiving pairs on one end of a cable so that hubs can hear each other is by using _______ cables.

    Explanation
    Crossover cables are used to connect hubs or switches directly to each other, without the need for a router or a modem. These cables have the sending and receiving pairs reversed on one end, allowing the hubs to hear each other's signals. This allows for communication between the hubs and facilitates the exchange of data.

    With 10BaseFL, the maximum distance between the hub and the node is _____ meters

    Explanation
    With 10BaseFL, the maximum distance between the hub and the node is 2000 meters. This is because 10BaseFL is a type of Ethernet technology that uses fiber optic cables to transmit data. Fiber optic cables have the ability to transmit data over longer distances compared to other types of cables, such as twisted pair cables. Therefore, with 10BaseFL, the maximum distance between the hub and the node is 2000 meters.

    True or false? Bridges operate on Layer 2 of the OSI

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Bridges operate on Layer 2 of the OSI model. This means that they work with MAC addresses to forward data packets between different networks or segments. They analyze the destination MAC address of incoming packets and use a forwarding table to determine the appropriate port to send the packet to. By operating at Layer 2, bridges can efficiently connect and divide network traffic, improving network performance and reducing collisions.

    What is a name for any device that interprets ones and zeros coming in from a port that then repeats the same signal out of another connected port?

    Correct Answer
    repeater
    Explanation
    A repeater is a device that receives a signal consisting of ones and zeros from one port and then repeats the same signal out of another connected port. It is used to extend the range of a network by regenerating and amplifying the signal, allowing it to travel further without degradation. The repeater essentially acts as a signal booster, ensuring that the data transmitted from one device reaches its intended destination without loss or corruption.

    How many bytes of data can a single Ethernet frame carry?

    • 500

    • 150

    • 1500

    • 15000

    Correct Answer
    A. 1500
    Explanation
    An Ethernet frame can carry a maximum of 1500 bytes of data. This is the standard maximum payload size for Ethernet frames, which includes the data being transmitted along with other header and trailer information. This limitation is set to ensure efficient and reliable transmission of data over Ethernet networks.

    A basic Ethernet frame contains seven pieces of information: Preamble, MAC address of the recipient, MAC address of the sender, length, the data itself, a pad, and ______ which enables nodes to recognize when bad things happen to data.

    Correct Answer
    Frame check sequence (CRC), CRC, Frame check sequence
    Explanation
    The missing piece of information in a basic Ethernet frame is the Frame check sequence (CRC). This sequence is used to enable nodes to recognize when bad things happen to data, such as errors or corruption during transmission. The CRC is a mathematical calculation performed on the data in the frame, and the result is appended to the frame as the frame check sequence. This allows the recipient node to verify the integrity of the received data by performing the same calculation and comparing the result to the frame check sequence.

    Sniffers order a NIC to run in ________ mode, making it process every frame it sees on the cable regardless of the MAC address

    Correct Answer
    promiscuous
    Explanation
    Sniffers are network monitoring tools that capture and analyze network traffic. When a sniffer is set to run in promiscuous mode, it means that the network interface card (NIC) is instructed to process every frame it sees on the cable, regardless of the MAC address. This allows the sniffer to capture all network traffic, including packets not intended for the sniffer's own MAC address. By running in promiscuous mode, sniffers can effectively monitor and analyze all network activity on the cable.

    To connect two or more hub, hubs must be ___________ using one uplink port and one regular port

    Correct Answer
    daisy-chained, daisy chained
    Explanation
    To connect two or more hubs, they must be "daisy-chained" using one uplink port and one regular port. This means that the first hub's uplink port is connected to the regular port of the second hub, and so on. This creates a chain-like connection, allowing the hubs to communicate with each other and expand the network.

    Ethernet was based off of what network topology?

    • Ring

    • Star

    • Bus

    • Point-to-point

    • Point-to-multipoint

    Correct Answer
    A. Bus
    Explanation
    Ethernet was based off of the bus network topology. In a bus network, all devices are connected to a single cable called the bus. Each device on the network can transmit data onto the bus, and all other devices can receive that data. This allows for easy communication between devices, as any device can transmit data to all other devices on the network. Ethernet, which is a widely used networking technology, initially used a bus topology before evolving to support other topologies such as star and ring.
