Networked Windowing Systems

We introduce networked windowing systems here as from the point of view of distributed systems they are really a communications mechanism. They have interesting requirements from the lower layers that distinguish them from other conventional communicating applications. We shall see in chapter 8 how they can be distributed to multiple users. Because all these machines have completely incompatible hardware, lots of different window systems have evolved. A consortium of computer manufacturers, software vendors and researchers decided to rectify this, by designing and implementing a free, portable windowing system. They called it X.
