Lectures are in room MU011 on Tuesday from 15.15 to 17.15. The practicals are in rooms MF124 (Group 1) from 09.15 to 12:05 & MF124 (Group 2) from 12.15 to 15:05 The Syllabus lists some of the core texts and finer details of this module from an administrative viewpoint.
The philosophy of this module is not to confuse you with ‘spagetti code’ for low level network device handling but rather to provide you with a theoretical underlying knowledge of networking and within the practicals to demonstrate the relative ease with which modern networks can be programmed to send information.
