The Chinese terms '聯(lián)網(wǎng)' (liánwǎng) and '連接' (liánjiē) both relate to the concept of connection or linking.

'聯(lián)網(wǎng)' specifically refers to connecting to a network, such as the internet, a local area network (LAN), or wireless network. It implies joining a system or infrastructure that enables communication or data exchange between devices, systems, or users.

'連接' is a broader term that means 'to connect' or 'to link.' It can refer to physical connections (like plugging in a cable), logical connections (such as establishing a relationship between data points), or abstract connections (like linking ideas).

In summary, '聯(lián)網(wǎng)' focuses on network connectivity, while '連接' is a general-purpose term for any type of connection.
