General review and evaluation
Students present their projects with practical examples

The aim of this course is to develop students'algorithmic thinking skills and help them understand the logic of data structures while learning how to use them to ensure data security, integrity, and efficient access.
Students will explore fundamental data structures such as arrays, linked lists, stacks, queues, trees, and graphs, and will learn their applications in cryptographic algorithms, log analysis, access control systems, and network security through practical exercises.
