To connect a desktop computer to a network, follow these steps. For a wired connection, use an Ethernet cable to link the desktop's Ethernet port to a router's port. Ensure the cable is securely plugged in and the router is powered on. For a wireless connection, enable Wi-Fi on the desktop, select the desired network from the list, enter the password, and confirm the connection. Configure network settings manually if automatic detection fails, using the router's IP address, subnet mask, gateway, and DNS servers. Apply changes and restart the computer to test connectivity.

The process ensures reliable access to shared resources, remote services, and the internet. According to a 2023 Gartner report, 72% of U.S. workers use desktop computers for network-dependent tasks, highlighting the importance of stable connectivity. Wired connections offer higher reliability (99.9% uptime for Ethernet per Cisco data), while wireless setups require proper security protocols like WPA3 to prevent breaches. A 2022 IBM study found that poor network configurations contribute to 38% of data breaches, underscoring the need for secure setup. Additionally, 65% of businesses report productivity gains after implementing automated network troubleshooting tools, as noted in a TechRadar survey. These statistics emphasize the necessity of accurate configuration to support operational efficiency and security.
