Detailed explanation-1: -There is little or no security which can leave them vulnerable. Users can access shared data which is centrally controlled. If any part of the network fails, a lot of disruption can occur.
Detailed explanation-2: -Disadvantages of the client-server network: A specialist network operating system is needed. Specialist staff such as a network manager is needed. Its cost is not affordable for normal users. If a large number try to send requests at the same time frame then a traffic congestion problem can be created.
Detailed explanation-3: -An important disadvantage of the client-server model is that if too many clients simultaneously request data, the server could become overloaded. This can cause network congestion or result in a denial of service.
Detailed explanation-4: -Servers can be expensive to buy and maintain. A network technician will often be required. Trickier to set up with specialist knowledge needed. Over-all set up cost is more expensive than a peer-to-peer network. Server failure will probably disrupt all computers on the network.
