NETWORK TOPOLOGY
Hello guys! It's me Isma here , i'm back again after 1 week break from updating my blog😂 I hope you guys have a nice and beautiful day ,don't be stress for those who have less than 1 month to facing the PSPM 😕
Okay!So today I am going to share about Network Topology 🔰
What is the definition of Network Topology ?
A network topology refers to the layout of the computers and devices in a communication. (easy to memorise right ? ) 😏
What are of Network Topology ?
- Physical topology - The arrangement of cabling , including the devices, location and cable installation.
2.Logical Topology - The path that data travels between computers on a network explained how data is actually transferred in a network as opposed to its physical design.
Time for video 😍
Opps sorry , check it by yourself using the link provided 😈😉

What are types of Network Topology ?
1)STAR TOPOLOGY
What is the definition ?
All the computers and other nodes on the network connect to a central device,thus forming a star.
How the data send and receive ?
- Use a central device where are nodes are connected using cables
- Data that travels from one node to another passes through the hub or switch until reach destination nodes.
What are the advantages using Star Topology ?
- Easy to install and maintain.
- If one node fails,only that node is affected.The other nodes continue operate normally.
- Easy to troubleshoot.
What are the disadvantages using Star Topology ?
- Requires more cable.
- More expensive.
- If one hub or switch fails,the entire network will be inoperable until the device is repaired.

2)BUS TOPOLOGY
What it's physical ?
- Consists of a single central cable(backbone), to which all computers and other devices connect
- Each devices is connected to the backbone through T-Connecter.
How do its's work ?
A signals are send as electrical pulse that travel along the cable to all nodes and only recipient accept data.
What are the advantages using Bus Topology ?
- Inexpensive and easy to install.
- Failure of one node usually does not affect the rest of the bus network
- Can be attached and detached at any point on the bus without disturbing the rest of the network.
What are the disadvantages using Bus Topology ?
- Difficult to identify the problem if the entire network failed/shutdown.
- If the backbone fails,the entire bus network will be affected.

.........OKAY LETS MOVE TO ANOTHER TYPES OF NETWORK TOPOLOGY 😔😆...
no video hmmm
3)RING TOPOLOGY
Explanation ?
A cable forms a closed loop(ring) with all computers and devices arranged along the ring.
How do it's work ?
Data travels from one node to another node in one direction until it reaches its destination by using token passing.
What are the advantages of using Ring Topology ?
- The transmission of data is relatively simple as packets travel in one direction only.
- Cable faults are easily located,making trouble-shooting easier.
- The uses of token passing enables all nodes in a ring topology to share the network resources fairly.
What are the disadvantages of using Ring Topology ?
- A failure in any cable or device breaks the loop and can take down the entire network.
- Data packets(token) must pass through every computer therefore,it makes it slower.
- Adding or removing nodes bring down the network temporary.
So , thats all I want to share for today blog.I hope you guys can read through it and learn something 💗 Thankyou ! And stay tuned to the following blogs 💁
