A local network is a group of interconnected devices within a limited area, such as a home, school, or office. These devices can include computers, printers, and smartphones, allowing them to share resources and communicate with each other. Local networks often use wired connections, like Ethernet cables, or wireless connections, such as Wi-Fi. Local networks can be set up using various hardware, including routers and switches. They enable users to access the internet, share files, and use shared devices like printers. Security measures, such as firewalls and passwords, help protect the network from unauthorized access.
