Exercise 1: Why TCP/IP Won Through Deployment, Not Technical Superiority — Possible Solution
====================================================================

Explanation:

Per the chapter, "OSI was designed as an actual protocol suite by an
international standards committee, meant to be deployed, not just
referenced. TCP/IP came out of DARPA-funded ARPANET research and was
deployed and battle-tested in the real world starting in the 1970s and
80s. By the time OSI's own protocol suite was anywhere near finished,
TCP/IP was already running the growing internet -- a real-world
deployment winning out over a more theoretically complete design that
arrived too late to matter."

The key distinction the chapter draws is timing and real-world use,
not which design was technically better on paper. TCP/IP had the
advantage of being built, deployed, and iterated on directly against
real operational networks for years while OSI's own protocol suite was
still being finalized through a formal standards process. By the time
OSI's actual protocols were ready for real deployment, an entire,
functioning, already-adopted network already existed running on
TCP/IP -- and migrating an already-successful, already-deployed network
to a completely different protocol suite would have meant discarding
real, working infrastructure and accumulated practical experience in
favor of a competing design that offered no urgent, compelling reason
to switch.

This is specifically a "real-world deployment" argument rather than a
"technical superiority" argument: the chapter never claims TCP/IP was
inherently better-designed than OSI's protocols -- only that it got
there first, in a form people were actually running, while OSI was
still being finished. Being first, proven, and already widely adopted
turned out to matter more than which design was theoretically more
complete or elegant.

WHY THIS WORKS AS AN ANSWER
------------------------------
This frames the answer specifically around timing and real-world
adoption (TCP/IP deployed and battle-tested first) rather than
claiming TCP/IP was technically superior, matching exactly what the
chapter itself argues rather than substituting a different, unstated
reason.
