VLAN

VLAN suitable for small network
 

  Well, I can't list the uses of VLAN because it's too many, but note that the most important use of VLAN is management. A network telecommunicate and transport information, using VLAN lets you determine who gets what data, so privacy and confidentiality is not compromised. Think about a supermarket, the office needs data about what fruit they need from the farmer next day, while the cashier only need network connectivity to send the cashing data to the Finance department. If no VLANs exist, all data gets mixed together, may create a heavy traffic load and compromise the data.

  So, to conclude, here I point out at least 4 advantages of using VLAN:
1) management,
2) security,
2) bandwidth usage, or traffic,
4) separation of data
