NETWORK TOPOLOGY

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 ?

1. 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 ?

1. Consists of a single central cable(backbone), to which all computers and other devices connect
2. 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.

NEXT...VIDEO...😏

.........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 💁
