Computer Networks
We teach through the METIS Academy educational portal in a face-to-face (daily) form, during which there is direct communication and interaction of the student with the lecturer and with other students in the virtual classroom, while the student can be in any place and is connected online.
Who is the training for?
For everyone who wants to learn the basics of working with computer networks.
Entry profile/requirements/prerequisites
An experienced PC user who already knows how to use a computer correctly and confidently at an advanced level in the command line, knows the general basics of programming common to all programming languages, efficient handling of files and directories in the Windows operating system, or versioning of files/directories using GIT technology. He also masters the basic constructions of any of the programming languages - sequence, branching, cycle and typical file formats (XML, JSON, CSV).
