What are the "Common Physical Components of a Network"
Correct Answer(s)
A. Switch
B. PC
C. Cable
Explanation
The common physical components of a network include a switch, which is a device that connects multiple devices together and allows them to communicate with each other. A PC, or personal computer, is another component that is connected to the network and can send and receive data. Cables are used to physically connect the devices together and transmit the data. MS Windows, which is a computer operating system, is not a physical component of the network. Electric power is necessary for the network components to function, but it is not considered a physical component of the network itself.
2.
Waht are the main Characteristics of a Network
Correct Answer(s)
A. Speed
D. Security
E. Scalability
Explanation
The main characteristics of a network are speed, security, and scalability. Speed refers to the rate at which data can be transmitted and received within the network. Security involves measures taken to protect the network from unauthorized access and ensure the confidentiality and integrity of data. Scalability refers to the ability of the network to accommodate increasing demands and expand its capacity without significant performance degradation. These characteristics are essential for a network to efficiently and effectively handle data flow and ensure smooth operations.
3.
What is the Network Topology
Correct Answer
B. pHysical layout of the devices and cabling
Explanation
The correct answer is "Physical layout of the devices and cabling." Network topology refers to the arrangement of devices and cables in a network. It describes how devices are connected and the physical layout of the network, such as whether it is a bus, star, ring, or mesh topology. The other options mentioned, such as shapes and size of the network, network structural design, and type of cabling used, are related to network topology but do not fully encompass its definition.
4.
What are the 3 main type of the Topology ?
Correct Answer(s)
A. BUS
D. Star
E. RIng
Explanation
The 3 main types of topology are BUS, Star, and Ring. In a BUS topology, all devices are connected to a single cable, forming a linear network. In a Star topology, all devices are connected to a central hub or switch, creating a centralized network. In a Ring topology, devices are connected in a circular manner, where each device is connected to two other devices, forming a closed loop network.
5.
What is the Bus Topology
Correct Answer
C. Linear BUS
Explanation
The correct answer is "Linear BUS." The bus topology is a network configuration in which all devices are connected to a single cable called a bus. In this topology, data is transmitted in a linear manner from one device to another. Each device on the network receives all transmitted data, but only the intended recipient processes it. This topology is simple and cost-effective, but it can be prone to performance issues if there are too many devices or if the main cable fails.
6.
What is logical bus topology
Correct Answer
A. Ethernet hub.
Explanation
The correct answer is "Ethernet hub." In a logical bus topology, all devices are connected to a central hub using a single cable. The hub acts as a central point for data transmission and allows multiple devices to communicate on the same network. This topology is commonly used in Ethernet networks, where the hub facilitates the communication between devices using the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol. It is important to note that logical bus topology refers to the way devices are connected and communicate, rather than the physical arrangement of cables.
7.
What is Star and Extended-Star Topologies
Correct Answer
A. Star network is expanded to include an additional network device
Explanation
The correct answer is "star network is expanded to include an additional network device". This means that in a star topology, where all devices are connected to a central hub or switch, an extra network device is added to expand the network. This could be another hub or switch that connects to the existing central device, allowing for more devices to be connected to the network. This expansion helps to increase the capacity and reach of the network.
8.
Extended-Star Topology are (choos 2 options)
Correct Answer(s)
A. A common deployment of an extended-star topology
B. Star hierarchical design of the network
Explanation
The correct answer options, "A common deployment of an extended-star topology" and "Star hierarchical design of the network," both describe characteristics of an extended-star topology. In an extended-star topology, multiple star topologies are interconnected, creating a hierarchical network design. This design allows for scalability and easier management of the network. Each star within the extended-star topology has its own central connection point, such as a hub, switch, or router, which connects to the central device of the overall network. This design is more efficient and easier to implement than a physical bus topology, where each device is connected to a single shared communication line.
9.
What is the problem with the pure extended star Topology
Correct Answer
A. If the central node point fails, large portions fail
Explanation
In a pure extended star topology, all nodes are connected to a central node. If the central node fails, it means that the entire network loses its connectivity. Since the central node is responsible for connecting all the other nodes, if it fails, it will result in a failure of a large portion of the network. Therefore, the correct answer is "if the central node point fails, large portions fail."
10.
What most of extended-star topologies employ (Choos 1 options)
Correct Answer
A. A redundant connection to a separate set of connection devcies
Explanation
Most extended-star topologies employ a redundant connection to a separate set of connection devices. This means that there is an additional connection available in case the primary connection fails, ensuring a backup and maintaining network reliability. By having a separate set of connection devices, the network can continue to function even if one set of devices experiences issues.
