Specialists in computer sciences (CS) are engaged in data and information gathering, storing and processing with different information technologies and facilities including software development. Thus, CS students are familiar with various operating systems, and they understand the special features of a program code and everything it conceals.
The students may try their hand at big data filed, data science, system and software design, web design, algorithm writing or data structures creation.
