What are the types of network topologies?





                                                                                                                                                               
💻What is network topology?
-Refers to the network's layout or structure as it relates to data flow. This is the arrangement of the elements (links, nodes, and so on) of a communication network. It refers to the physical or logical arrangement of your network's nodes, devices, and connections. It shows how devices are connected and data is sent from one computer to another in a network.

                                                                                                                                                  

💢Types of Network Topologies

                                                                                                                                                  

☆ Star Topology
- It use a central device known as a hub, from which cables extend in all directions.

☆ Advantage of star topology
- Lack of disruptions to the network when connecting or removing devices.

☆ Disadvantage of Star topology 
-If the hub fails, attached nodes will not be able to use the network resources.

                                                                                                                                                               

🚌Linear Bus Topology
- Connects computers and other devices to a single lengthy connection referred to as a backbone.

🚌Advantages of Linear Bus Topology
1.  Cost effective. 
2.  Less cables required.
3.  Easy installation, each cable needs to be connected with 
      backbone cable.

🚌Disadvantage of Linear Bus Topology
- The disadvantage is that the entire network shuts down if there is a break in the backbone.

d                                                                                                                                           
    
💍 Ring Topology
-Is a network topology in which nodes are linked to one another in a ring configuration to produce a single contiguous pathway.

💍 Advantage of Ring topology
-There's no need for a network server to manage workstation connectivity.

💍Disadvantages of Ring Topology

1.  Data traffic issues.
2.  If a node fails, then the entire link gets disrupted.

                                                                                                                                              
 
💮Mesh Topology
- Are network architectures in which every nodes on the network may autonomously route data flow

💮Advantages of Mesh Topology

1. The central device handles all data traffic and user requests.
2. No data traffic issues.
3. Secure.


💮Disadvantage of Mesh Topology
- If the connection to the central hub breaks down, then all communication is lost between that node and the network.

                                                                                                                                               

⛶ Hybrid Topology
- Is a network that com
bines two or more distinct topologies in such a way that the resulting network does not display one of the standard topologies' features.

⛶ Advantage Hybrid Topology
-We can choose the topology based on the requirement for example, scalability is our concern then we can use star topology instead of bus technology.

⛶ Disadvantage Hybrid Topology
1. Fault detection is difficult.
2. Installation is difficult.
3. Design is complex so maintenance is high thus expensive.

 What is a network or IP address?                                                                                                           💻What is that? 💻     -  An IP address is a one-of-a-kind identifier for a device on the internet or within a local network. The term  (IP) "Internet Protocol" refers to a collection of rules that regulate the format of data transferred over the internet or a local network. 💻  - A series of digits separated by periods makes up an IP address. IP addresses are made up of four numbers; for example, 192.158.1.38 is an example address. The set's numbers can vary from 0 to 255. As a result, the entire IP addressing range is 0.0.0.0 to 255.255.255.255.   ...

 What are the types of computer networking? ddddddddddddddddddddddddddddddddddddddddddddddddddddd 💓Metropolitan area network (MAN)   - is a computer network that connects  computers  in a metropolitan region,  which can be a single large city, a  collection of cities and towns, or  any other large area with several buildings. 💓Wide area network (WAN) -  is a huge network of data that isn't bound to a single location. Through a WAN provider, WANs can permit communication, information sharing, and much more between devices all over the world. 💓 Personal area network (PAN) - It establishes a connection between electronic devices within a user's close vicinity. A PAN can be anything from a few millimeters to several meters in length. The link between a Bluetooth earpiece and a smartphone is one of the most common real-world instances of a PAN. Laptops, tablets, printers, keyboards, and other technological devices can all  be connected using PA...
