New topic was introduced at ICT classes: Computer Networks. It turned out that this is a very interesting issue, because you can get familiar with general rules for operations and transfer of data between computers. The teacher started the lesson by introducing the concepts such as: computer networks, protocols, IP address, and acquainted us with the structure of the data and introduced two network models: OSI and TCP / IP. I had difficulty to understand why to transfer data across the network layers are required in models and that each layer works with different protocols. I spent a lot of time searching for information on the Internet, checking the available books and repeatedly talked to the teacher to clarify issues of my interest. Finally, I realized that the sense of the creation of computer networks was to improve and bring a higher level of communication and data sharing in the world (it works practically in the whole world). The network allows quick and easy access to the published data, as well as opens the technical ability to create and use common resources.
