This module aims to provide you with an understanding of the fundamental behaviour and components of a typical computer system, and how they collaborate to manage resources and provide services in scales from small embedded devices up to the global internet. You will be introduced to IP networks exemplified through the TCP/IP and OSImodels. Laboratory sessions will give you hands-on experience on constructing and configuring network devices. You will use the Cisco CCNA introduction to data network technology course which is the first of four Cisco courses that can be used to obtain a Cisco CCNA qualification. This module will lay the foundation of and prepare you for the computer software, computer networking and cyber security sector to name a few.

During this module you will be introduced to the fundamental features of modern operating systems, their components and their use. We will look at key concepts including the kernel and its modes; memory and resource management; file systems, security and authentication; single and multi-tasking; interrupts, hardware and device drivers and command line and graphical user interfaces (GUI). Case studies will introduce you to command line interface (CLI) commands and scripting in both the Windows CLI and a Linux shell and allow you to develop simple scripts to automate activities in both operating system environments. You do not need any special technical knowledge before undertaking the module, however a basic user level familiarity with a GUI based operating system (such as Windows) will be useful. The skills acquired in the module will enable you to go on to study material in later modules which involve topics such as system administration, network and server configuration and technical support, all of which are key skills you may need as a graduate when working in the systems and network support industries.

As a student embarking on a degree in computer science or a closely related discipline, this module will equip you with the core mathematical skills needed to succeed. This module also contributes to the professional body accreditation of your programme of study, reflecting the criticality of mathematics/statistics skills in professional computing roles and in computer science research. During much of the module, you will be studying topics in discrete mathematics, such as set theory and logic, Boolean algebra, functions, matrices, sequences/series and product/summation notations. Further topics include probability and statistics, which are useful in understanding the behaviour of non-deterministic algorithms, data visualisation, and in the design and implementation of computer science research projects. The topics you will study will be directly related to computing principles. For example the use of set theory for: the representation of computational structures such as lists, trees and graphs; computations on discrete collections of data (such as in databases); the relationship between number classes and data types and in evaluating computability; and parallels between set theoretic operations and programming logic. The relationship between Boolean algebra and logic operators used in computer programming will be discussed, along with topics like the evaluation and simplification of Boolean expressions. Topics such as sequences and series will be related to elementary algorithm complexity (e.g., linear, logarithmic, and exponential functions), and mathematical functions (injective, surjective, bijective) will be related to program functions, with common functions found in nearly all non-trivial computer programs (such as modulus, floor/ceiling, and numerical operations such as gcd and lcm) being introduced and demonstrated in context. Permutations and combinations will be related to computer security, and the notion of intractable computational problems. Matrices will be in discussed in terms of their ability to represent computational structures such as images, graphs, and computer networks. Core descriptive and inferential statistics used for data visualisation and hypothesis testing (including histograms, distribution types, measures of central tendency and dispersion, and basic inferential statistics such as t-tests and linear correlation) will be examined. Mathematics and statistics skills are regarded as a core competency in computing professionals, and graduates with these skills are highly valued by employers in all job roles in computing and more widely.

Data Structures and Algorithms is described in the ACM/IEEE Joint Task Force for Computing Curricula as being 'Fundamental to computer science and software engineering' which also notes that 'Algorithms are essential in all advanced areas of computer science: artificial intelligence, databases, distributed computing, graphics, networking, operating systems, programming, security, and so on'. In this module you will examine the core data structures and algorithms used in all nontrivial software, enabling you to make sound decisions in the construction of computing solutions that have specific constraints in terms of time (speed) and space (memory). You will learn how to compare the asymptotic behaviour of fundamental computational structures and algorithms and develop the critical skill of making evidence-based choices when selecting from among multiple possible approaches to a given computational problem. To accomplish this, you will study the core mathematical concepts that provide a framework for computational and analytical thinking independently of any particular programming language or computing architecture. In a highly cited cover article by the IEEE Computer Society, What knowledge is important to be a software professional?, the results of a survey of 186 software professionals are presented in which they were asked which topics in Computer Science degree programmes they believed to be the most important. Data Structures & Algorithms was rated the second most important topic, preceded only knowledge of "specific programming languages". The importance of this module to your future career in software development or technical/scientific computing cannot be overemphasised.
