Postavení a možnosti sociálních sítí v době koronavirové krize

This bachelor thesis is focused on using social networks and other means of online communication during the pandemic of SARS-CoV-2, which for the first time appeared in Czech Republic in March 2020. For this reason, there has been a significant change in the lifestyle of every citizen. The biggest change probably occurred in the area of social contacts and communication. The main goal of this thesis is to find out whether this fact is reflected in the number of users older than fifty years or in the reasons for which social networks or other means of communication are used. This research is carried out using an internet questionnaire. In the individual chapters two researched groups of services, which are being used for communication over the internet, are characterized. Further on their specific examples are described, including their functions and history. A description of the most common threats that anyone may encounter when communicating online is also included. The practical part evaluates the answers received from the survey. In conclusion, in addition to the results of the survey, there is also a reflection of the work, evaluation of the objectives and recommendations for those who would try to perform their own research with a similar focus.
