The most often used information technologies in the future professional activity of students of pedagogical universities are computer technologies of text, tabular and graphic data processing, work with multimedia data, as well as computer telecommunications. Mastering the skills of working with these technologies involves the study of office suites that allow you to perform data processing work. The use of information and communication technologies provides ample opportunities for the organization of educational and cognitive activities of students.
