A user’s house is connected to a network through their laptops, desktop computers, cellphones, and other smart appliances and digital gadgets, creating a home area network (HAN). Thus, it makes it easier for digital gadgets linked to a home’s network to communicate with one another. Wireless or wired home networks are both possible. For HAN, wireless networks are primarily used. The Network Address Translation function is performed by a single, centralized device (NAT). This home area network enables resource sharing and communication between smart devices via a network connection.
