Describe the ways in which the request-reply protocol masks the heterogeneity of operating
systems and of computer networks.

What will be an ideal response?


(i) Different operating systems may provide a variety of different interfaces to the communication protocols.
These interfaces are concealed by the interfaces of the request-reply protocol.
(ii) Although the Internet protocols are widely available, some computer networks may provide other
protocols. The request-reply protocol may equally be implemented over other protocols.
[In addition it may be implemented over either TCP or UDP.]
