COMP18112: Fundamentals of Distributed Systems (2012-2013)
Distributed systems take many forms, and many of the best known and most widely used computer systems are as prevalent as they are because of their distributed nature. This course unit introduces some of the essential concepts underlying distributed systems.
Students are guided into an exploration of exemplar distributed applications (such as the web, email, internet telephony and multi-user gaming ) and, through these exemplars, are introduced to the basic concepts that underpin modern distributed computing.
Recurring themes will include how distributed systems offer transparencies of various kinds and how they must contend with a range of complex issues to achieve that.
This course unit aims to provide students with a basic understanding of distributed computing, drawing on their general experience as users of distributed applications to inform the discovery, description and classification of fundamental concepts in distributed systems.
This course unit builds on the knowledge gained by students in COMP10120: The First Year Team Project course unit and aims to equip them better to benefit from more technically-demanding course units in second and third years (in particular, the course units on Computer Networks, Distributed Computing and Mobile Systems).
After a brief introduction that contrasts the distributed view of computing with the centralized one presented in other course units, the course unit progresses by studying a few exemplar distributed applications, one by one. Each exemplar application is chosen with a view to illustrating issues and challenges arising in distributed systems.
After each dissection of an exemplar application, time is taken to make explicit, in a more systematic way, some of the basic principles involved, how tools and techniques have been developed that enforce those principles, and how these tools and techniques both give rise and presuppose the distributed computing infrastructures that pervade

Conclusion: A Look Into the Future 
There are no books that cover the syllabus exactly. The book by Tanenbaum and van Steen (details below) is used in the second-year Distributed Computing course unit but it is far too advanced for COMP18112. Nonetheless, in the COMP18112 website (see link above) there's some information linking topics and lectures in COMP18112 to sections and places in the Tanenbaum and van Steen book where a more advanced treatment is provided.
