Network setup refers to the process of establishing a communication system that connects multiple devices, such as computers, printers, and smartphones, to share resources and information. This involves configuring hardware components like routers, switches, and access points, as well as setting up software settings to ensure devices can communicate effectively. During network setup, users typically need to assign unique IP addresses to each device, configure firewalls for security, and establish Wi-Fi connections for wireless devices. Proper network setup ensures reliable connectivity, efficient data transfer, and protection against unauthorized access, making it essential for both home and business environments.
