Bus Topology
Overview:
Bus topology is a network setup where each computer and network device is connected to a single cable or backbone. This type of topology is easy to install and doesn't require much cable compared to other topologies, making it cost-effective for small networks.
Advantages:
Simple to set up and extend, requires less cable length than a star topology.
Disadvantages:
If the main cable fails, the entire network goes down. Troubleshooting can be difficult.
// Example of a simple bus network setup in a pseudo-code
class BusNetwork {
public static void main(String[] args) {
String[] devices = {"Computer1", "Computer2", "Computer3"};
String backbone = "MainCable";
for (String device : devices) {
System.out.println(device + " connected to " + backbone);
}
}
}
Console Output:
Computer1 connected to MainCable
Computer2 connected to MainCable
Computer3 connected to MainCable
Star Topology
Overview:
In a star topology, all nodes are connected to a central hub or switch. This topology is commonly used in home networks and large organizations due to its reliability and ease of troubleshooting.
Advantages:
Easy to install and manage, failure of one cable doesn't affect others.
Disadvantages:
If the central hub fails, the whole network is affected. Requires more cable than bus topology.
// Example of a star network setup in a pseudo-code
class StarNetwork {
public static void main(String[] args) {
String hub = "CentralHub";
String[] devices = {"Computer1", "Computer2", "Computer3"};
for (String device : devices) {
System.out.println(device + " connected to " + hub);
}
}
}
Console Output:
Computer1 connected to CentralHub
Computer2 connected to CentralHub
Computer3 connected to CentralHub
Ring Topology
Overview:
Ring topology connects each node to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring. Data travels in one direction, reducing the chance of packet collisions.
Advantages:
Data packets travel at great speed, no data collisions.
Disadvantages:
Failure of a single node can disrupt the entire network. Difficult to troubleshoot.
// Example of a ring network setup in a pseudo-code
class RingNetwork {
public static void main(String[] args) {
String[] devices = {"Computer1", "Computer2", "Computer3"};
for (int i = 0; i < devices.length; i++) {
System.out.println(devices[i] + " connected to " + devices[(i + 1) % devices.length]);
}
}
}
Console Output:
Computer1 connected to Computer2
Computer2 connected to Computer3
Computer3 connected to Computer1
Mesh Topology
Overview:
Mesh topology involves each node being connected to every other node in the network. This provides high redundancy and reliability, as data can be rerouted if one path fails.
Advantages:
Highly reliable and redundant, easy to detect faults.
Disadvantages:
Expensive due to the large number of cables required, complex installation and management.
// Example of a mesh network setup in a pseudo-code
class MeshNetwork {
public static void main(String[] args) {
String[] devices = {"Computer1", "Computer2", "Computer3"};
for (String device1 : devices) {
for (String device2 : devices) {
if (!device1.equals(device2)) {
System.out.println(device1 + " connected to " + device2);
}
}
}
}
}
Console Output:
Computer1 connected to Computer2
Computer1 connected to Computer3
Computer2 connected to Computer1
Computer2 connected to Computer3
Computer3 connected to Computer1
Computer3 connected to Computer2
Hybrid Topology
Overview:
Hybrid topology combines two or more different types of topologies. For example, a star-bus topology is a combination of star and bus topologies, providing flexibility and scalability.
Advantages:
Flexible and scalable, can be designed to suit specific needs.
Disadvantages:
Complex design and implementation, can be costly.
// Example of a hybrid network setup in a pseudo-code
class HybridNetwork {
public static void main(String[] args) {
String[] starDevices = {"StarDevice1", "StarDevice2"};
String[] busDevices = {"BusDevice1", "BusDevice2"};
String centralHub = "CentralHub";
String mainCable = "MainCable";
for (String device : starDevices) {
System.out.println(device + " connected to " + centralHub);
}
for (String device : busDevices) {
System.out.println(device + " connected to " + mainCable);
}
}
}
Console Output:
StarDevice1 connected to CentralHub
StarDevice2 connected to CentralHub
BusDevice1 connected to MainCable
BusDevice2 connected to MainCable
Tree Topology
Overview:
Tree topology is a combination of star and bus topologies. It features a root node and all other nodes are connected to it, forming a hierarchy. This topology is ideal for large networks.
Advantages:
Scalable, easy to manage and maintain. Ideal for hierarchical networks.
Disadvantages:
If the root node fails, the network becomes unstable. Complex to configure.
// Example of a tree network setup in a pseudo-code
class TreeNetwork {
public static void main(String[] args) {
String root = "RootNode";
String[] level1 = {"Node1", "Node2"};
String[] level2 = {"Node3", "Node4"};
for (String node : level1) {
System.out.println(node + " connected to " + root);
}
for (String node : level2) {
System.out.println(node + " connected to Node1");
}
}
}
Console Output:
Node1 connected to RootNode
Node2 connected to RootNode
Node3 connected to Node1
Node4 connected to Node1
Point-to-Point Topology
Overview:
Point-to-point topology is a direct connection between two nodes. It is the simplest and most straightforward topology, ideal for small networks where only two devices need to communicate.
Advantages:
Simple and easy to understand, requires minimal configuration.
Disadvantages:
Limited to two nodes, not scalable.
// Example of a point-to-point network setup in a pseudo-code
class PointToPointNetwork {
public static void main(String[] args) {
String device1 = "Computer1";
String device2 = "Computer2";
System.out.println(device1 + " connected directly to " + device2);
}
}
Console Output:
Computer1 connected directly to Computer2
Daisy Chain Topology
Overview:
Daisy chain topology connects each node to two others, forming a chain. It is a simple and cost-effective way to connect a series of devices in a linear sequence.
Advantages:
Simple to implement, requires fewer cables than a full mesh topology.
Disadvantages:
If one node fails, it can disrupt the entire chain. Not suitable for large networks.
// Example of a daisy chain network setup in a pseudo-code
class DaisyChainNetwork {
public static void main(String[] args) {
String[] devices = {"Computer1", "Computer2", "Computer3"};
for (int i = 0; i < devices.length - 1; i++) {
System.out.println(devices[i] + " connected to " + devices[i + 1]);
}
}
}
Console Output:
Computer1 connected to Computer2
Computer2 connected to Computer3
