Switch.
Adding a switch improves network performance by allowing for dedicated pathways for data to travel between devices, reducing congestion and collisions that can occur in shared networks. Switches can also store and forward data packets more efficiently, leading to lower delays in transmitting information compared to traditional hub-based networks.
There is no need to use subnetting if you have no wish to further divide up your network into smaller, logical networks.
provide connectivity between smaller local networks
When you borrow bits for a subnet you are intruding into the client portion of an IP address. As a result, you will lose clients in your network because the "borrowed" portion becomes the extended network prefix. This allows you to separate your bigger network into smaller, logical networks (subnets). The number of bits borrowed will indicate the total number of smaller subnets that you can support in your network. In each case, regardless of class of address, borrowing 4 bits gives a total of 14 subnets (in the classical sense) and 16 subnets (in Cisco).
Security. People on the larger network can't see the smaller subnet, good for departments like Research.
Definition: A subnet is a logical grouping of connected network devices. Nodes on a subnet tend to be located in close physical proximity to each other on a LAN.The pourpose of subnetting is not to provide extra addresses, but to keep network data separated to prevent congestion.
