A home network is a system that connects various devices within a house, allowing them to communicate and share resources. This can include computers, smartphones, tablets, and smart home devices like smart speakers and security cameras. By using a router, these devices can access the internet and share files or printers with each other, making everyday tasks easier. Setting up a home network typically involves connecting a modem to a router, which then distributes the internet connection wirelessly or through cables. Home networks can be secured with passwords to protect personal information and ensure that only authorized users can access the network.
