Network Topologies

Question 1

It is a schematic description of a network arrangement , connecting various nodes (sender and receiver) through lines of connections

Answer 1

Network Topologies

Question 2

in this type of topology, the computers are connected to a single hub through a cable. This hub is the central node while all other nodes are connected to it.

Answer 2

Star Topology

Advantages: New nodes can easily be added to the network. Communicatio data must be forwarded by the central node, which facilitates network monitoring.

Disadvantages: Faults on the central node affect the entire network’s communication.

Question 3

a network type in which **every computer and network device is connected to a single cable. **When it has exactly two (2) endpoints, then it is called Linear Bus Topology. All nodes are connected through a bus (ex. coaxial cable)

Answer 3

Bus Topology

Advantages: The installation is simple and cable resources are saved. Generally, the failure of a node does not affect the communication of the entire network.

Disadvantages: A bus fault affects the communication of the entire network. The information sent by a node can be received by all other nodes, resulting in low security

Question 4

forms a ring as each computer is connected to another computer, with the last one (1) connected to the first - exactly (2) neighbors for each device.

Answer 4

Ring Topology

Advantages: Cable resources are saved
Disadvantages: It is difficult to add new nodes. The original ring must be interrupted before new nodes are inserted to form a new ring.

Question 5

has a root node and all other nodes are connected to it forming a hierarchy. It is also called hierarchical topology. It should at least have three (3) levels to the hierarchy.

Answer 5

Tree Topology

• Advantages: Multiple star networks can be quickly combined
• Disadvantages: A fault on a node at a higher layer is more severe.

Question 6

a point-to-point connection to other nodes and devices. All the network nodes are connected.

Answer 6

Mesh Topology

Question 7

Two (2) Types of Mesh Topology

Answer 7

• Partial Mesh Topology
• Full Mesh Topology

Question 8

in this topology, some systems are connected in the same fashion as mesh topology, but some devices are only connected to two (2) or three (3) devices

Answer 8

Partial Mesh Topology
Advantages: The cost of partial-mesh network is lower than that of full-mesh network.
Disadvantages: The reliability of a partial-mesh network is lower than that of a full-mesh network.

Question 9

each node or device is connected.

Answer 9

Full Mesh Topology

Advantages: It has high reliability and high communication efficiency
Disadvantages: Each node requires a large number of physical ports and interconnection cables. As a result, the cost is high, and it is difficult to expand.

Question 10

it consists of mix of two (2) different types of topologies merging as one network

Answer 10

Hybrid Topologies

• In actual networking, multiple types of topologies may be combined based on the cost, communication efficiency, and reliability requirements.
