There is an increasing demand in the industry for graduates with problem solving skills; those with the capability of applying the theories, methods and techniques learnt during their degree programme in solving real life problems. The goal behind applied computer science programme is to produce such graduates who can easily integrate into the industry immediately after college and become indispensable problem solvers. Another goal of the applied computer science programme is to produce entrepreneurs who can create opportunities and bring about innovative solutions. Knowing fully well the demand of the industry, Project 2 has been designed to help students consolidate the knowledge and skills acquired during the course of the degree programme by developing systems (hardware or software) that are applicable to the market. Such systems as a matter of fact should contribute by addressing gaps in the market and should mainly target areas that need solutions unique to the African region. This is not in any way to limit students’ horizon; they should think globally but be able also to customize their solutions to the region.

This course examines computers anthropologically, as artifacts revealing the social orders and cultural practices that create them. Students read classic texts in computer science along with cultural analyses of computing history and contemporary configurations. It explores the history of automata, automation and capitalist manufacturing; cybernetics and WWII operations research; artificial intelligence and gendered subjectivity; robots, cyborgs, and artificial life; creation and commoditization of the personal computer; the growth of the Internet as a military, academic, and commercial project; hackers and gamers; technobodies and virtual sociality. Emphasis is placed on how ideas about gender and other social differences shape labor practices, models of cognition, hacking culture, and social media.

Progressively more, people and organizations depend on the availability of computer networks to carry out various activities such as professional, academic or leisure. Computer networks have become a critical piece of any information system.

Imagine a single computer without being connected to any other computer: this machine will only have access to your information (found on your Hard Disk) or information that may come from floppies, flashes, CD’s and DVD’s.

When a computer is connected to a computer network, you can have access to information that comes to you and to present information on other computers connected to the same network, allowing a much larger number of possible information to access through that computer. However, it must recognize that computer networks today have little to do with networks used for several years, taking advantage of technological advances in transmission capacity of the physical, logical means, processing capacity of the equipment and functionality of the protocols and applications.

Throughout the module will use the term “computer network” when we want to mention a collection of autonomous computers connected by a single technology. Two computers are interconnected when they can exchange information. The connection do not need to be made by a copper wire; they can also use optical fibers, microwaves, infrared waves, and communication satellites. There are networks in many sizes, shapes and forms, as we shall focus on.

“Every program depends on algorithms and data structures, but few programs depend on the invention of brand new ones.”! “I will, in fact, claim that the difference between a bad programmer and a good one is whether he considers his code or his data structures more important. Bad programmers worry about the code. Good programmers worry about data structures and their relationships.”!

This course introduces students to data structures and algorithms, and how data structures can be created and used. The application of data structures will be presented on the basis of various algorithms. This course teaches learners the way information is organized in the computer and which have an impact on the performance of the computer. The purpose of this course is to provide the students with solid foundations in the basic concepts of programming: data structures and algorithms. The main objective of the course is to teach the students how to select and design data structures and algorithms that are appropriate for problems that they might encounter. This course is also about showing the correctness of algorithms and studying their computational complexities. This course offers the students a mixture of theoretical knowledge and practical experience. The study of data structures and algorithms is carried out within an object-oriented framework. When implementations are considered, the Java programming language is used.

This course focuses on basic and advanced techniques on data warehousing and data mining, the study of the processing, modelling, querying, organizing, classifying documents, identifying association rules and categorization.
