Short Description:

Software technology. Software life cycle, development process models, modularity. Data structures. The meaning of table. Records, linked lists. Abstract data types. Trees - binary trees. Graphs. Files structures. Databases and database models. Relations, entities, fields. Base operations. Structured Query Language (SQL). Data compression (image, sound, video). Data security, public and private encryption key. Authentication, key management, digital signature. Calculation theory. Introduction to artificial intelligence (knowledge representation, expert systems, visual processing, pattern recognition). The course is combined with tutorials and labworks on such topics as networks, algorithm development, databases, audio and visual processing, programming in assembly language and high level language.

Objectives - Learning Outcomes:

The course is the continuation of the TEC110 course.
The aim of the course is to set the introductory bases for understanding the capabilities of Computer Science. The basic principles of operation and the structure of computers are briefly covered, while at the same time introducing the basic chapters concerning Computer Science, such as Computer Logic, Data Organization and various other advanced topics, e.g. Compression of Data, Computer Security and Computer Theory. The emphasis is on Students learning how to search for new sources of knowledge, apply this knowledge to other subjects of the Department Curriculum, to use it in problem analysis and in the creation or evaluation of Audiovisual Art (interactive, web-based, video, game, etc.).
