IntroductionNetwork Topology is a network of computers that are connected and arrange in a specific manner. In Networks, computers are connected with other computers this structure and design are called topologies.
In this article, we are going to learn and discuss 10 applications of star topology in Computer networks and what is star topology.
Let’s get started.
Applications of Star Topology
Let us try to understand and discuss 10 applications of star topology.
- Star topology is the most used and popular topology using LANs. The star topology was first seen by ARCNET [Attached Resource Computer Network]
- Star topology is used in small networks.
- They are used in small organizations
- They use LAN connections for high speed up to 100MBPS.
- Star Topology is used in small institutes.
- All the devices are connected to each other via HUB or SWITCH
- All the nodes are connected to the central HUB and if any node is failed doesn’t harm or damage the entire network.
- These star networks are quiet cheaper compares to other network topologies.
- They are very easy in maintenance and up gradation.
- They are scalable node can be added any time user request or demand.
What is Star Topology?
In Star topology computers, laptops, printers, and scanners are connected with a networking device known as HUB.
The HUB acts as the communicating device which receives and transfers information and data between computers and laptops through them [HUB].
Whenever the computers and laptops in the computer network need to communicate with each other i.e. receive or transfer data and information they need to interact with the HUB.
And hence HUB acts as the intermediate device which helps in communicating with other devices in the network.
HUB is centered in the structure or the design of the star topology where all the devices like laptops, computers, and printers are connected to each other.
The design and structure form a figure like a star, therefore, this type of topology is called as Star Topology.
Which Devices are used in Star Topology?
The devices which are used in the star topology
- Switch or HUB
- Cable Cat5 and Cat6
- RJ45 or RJ11
- Coaxial Cable
- Optic Fiber
- Twisted Pair Cable
- Computer and Laptops
Advantages of Star Topology
- The computer, laptop, scanner and printer are called nodes in the star topology. If any of the node is fail doesn’t affect whole network.
- They are easily installed and maintained
- They can be easily updated and up-graded new nodes can be easily added anytime users demands.
- They are cheap.
- They are easy to troubleshoot
- They are fast networks.
Disadvantages of Star Topology
- The star topology is heavily dependent on centralized HUB or SWITCH.
- The number of devices connected to the star network depends on the switch or HUB.
- If majority of the nodes are operating at the same time put loads on the network and hence the speed is decreased considerably.
- To manage and maintained can be costly sometimes depending upon some conditions.
- They are dependent on electric supply.
Types of Computer Topology
There are five computer topologies that are
- Bus Topology
- Ring Topology
- Star Topology
- Mesh Topology
- Tree Topology
