It is expensive to set up

|
|
Expensive to add new devices
|
|
|
Very poor data security
|
Detailed explanation-1: -High cost: Central device Dependency: High maintenance: Prone to damage: Low data transfer rates in the wireless system: Immobile network system:
Detailed explanation-2: -Star topologies are easy to manage in most ways but they are far from cheap to set up and use.
Detailed explanation-3: -In Star Topology, the data travels from the central hub or router to all the nodes. In Mesh Topology, the data travels from one node to the other. Star Topology is very good extensible and which can be used in LAN as setup is easy too. Mesh Topology is poor extensible and which can be used in WAN.
Detailed explanation-4: -The main disadvantage of this topology is that it requires a network protocol to detect when two nodes are transmitting at the same time. It also does not cope well with heavy traffic rates.
