|Aims |The module is structured following the Open Systems |
| |Interconnect (OSI) model and consists of two parts. |
| |The first part of the module focuses on the concepts|
| |and mechanisms that are employed in the 2nd layer of|
| |the OSI model, the data link layer. This layer is |
| |concerned with the delivery of data between two |
| |immediately connected devices i.e. devices that |
| |share a common physical medium. The layer |
| |coordinates the access to the physical medium and |
| |attempts to detect and correct errors introduced by |
| |the transfer of signals over the physical medium. |
| |The concepts that are employed in this layer are |
| |discussed and the students exercises that |
| |demonstrate the application of these concepts. |
| |The second part of the course focuses on the 3rd and|
| |4th layer of the OSI model. The 3rd layer, the |
| |network layer, focuses on the connection of local |
| |area networks (LANs). This layer employs concepts |
| |that hide the communication through a LANs and |
| |provide an abstraction that allows the communication|
| |across various interconnected LANs. This abstraction|
| |forms the foundation for today's internet and |
| |represents essential knowledge for today's computer |
| |science graduates. The 4th layer, the transport |
| |layer, provides services such as reliable transport |
| |to applications. The understanding of the mechanisms|
| |employed in this layer is essential to the |
| |understanding of the implementations and performance|
| |of current network technology. |
|Learning |When students have successfully completed this |
|Outcomes |module they should be able to |
| |explain the key concepts of networking technologies.|
| | |
| |describe different mechanisms for error detection |
| |and correction. |
| |illustrate the communication between networked |
| |applications. |
| |analyse communication problems between devices |
| |connected by various media. |
