Bridging refers to the transfer of assets across different blockchain networks. Bridges are the platform and infrastructure used to execute the transfer and share data across chains.

Cross-chain swaps provide a similar function to bridges and enable users to transfer tokens across different blockchain networks and receive different output tokens than the token input (Ex, USDC on ETH swapped for ETH on Arbitrum).
