Local name resolution refers specifically to the process of resolving computer names to their corresponding network addresses within a local network. This is typically accomplished through protocols such as NetBIOS, WINS, or local host files, allowing devices on the same network to communicate efficiently by using easily recognizable names instead of numerical IP addresses.

When a user attempts to connect to another device on the same network, the local name resolution method ensures that the correct network address is determined quickly, enabling seamless communication.

The other options relate to broader or different contexts of name resolution. Mapping IP addresses to domain names pertains to the function of the Domain Name System (DNS) at a global level. Caching DNS responses deals with storing DNS query results to improve speed for future requests, focusing on efficiency rather than local resolution. Providing external DNS queries involves contacting external DNS servers to resolve names not contained within the local network, which is not the focus of local name resolution tasks.
