Berkeley Sockets in writing distributed applications

Question

In what respects is Berkeley Sockets an inefficient way to write distributed applications?

Answer 1

Berkeley Sockets use message passing between client and server without caring the required conversion for data formats, supported by heterogeneous hosts. The (remote) procedure's (local data) parameters into a format suitable for network transportation and again into a format that can be used on the remote host. The network-transparent transmission of data makes sure both end machines can interpret the information content correctly.
