This study focuses on the consumer experience of telecommunications service quality in Malaysia. Malaysia's penetration rate has gone over 100 percent, meaning that each person in Malaysia has at least one account registered with the telecommunications provider. Telecommunications industry competition is becoming fierce as there is a limited market available to share among the industry players. This study used a quantitative approach, using a questionnaire to collect data through random sampling. One hundred and fifty available respondents received, using SEM-PLS analysis. Results indicate that customers are more concerned with service quality and trust than brand image and price. Brand image and price did not impact consumer loyalty. One of the critical factors is that the facilities and packages provided are approximately the same price ranges for almost similar coverage areas. The service provider will use the outcome for their ongoing long-term plan.

Security is one of the most important aspects of data transmission. To provide controlled access to the network, user authorization and authentication are often used with the help of an AAA server. RADIUS servers provide users with access to data, user authentication, and configuration information. When designing networks with such access control method implementation, it is necessary to understand how the characteristics of the communication channel affect the switching time of IP-TV channels, and therefore the overall quality of IP-TV services. The principles of the main protocols for IP-TV using a RADIUS server are described. The main parameters of the communication channel were identified. The mathematical model and the graphs demonstrate how IP-TV service access time depends on telecommunication channel parameters. The results of a practical experiment are presented to prove the formed mathematical model. The results of a practical experiment and theoretical calculation are compared.

Available research suggests using Blockchain in electronic medical files to aggregate and integrate information. While reviewing authoritative articles and books, we analyzed the challenges and opportunities of using Blockchain this way. By using the specialists' opinion, completing a specialist questionnaire, using the DEMETEL technique and interpretive structural modeling (ISM) technique, this research investigated and analyzed the possibilities of using Blockchain in electronic medical files. The pair comparison technique was used to study and analyze the challenges of using Blockchain this way. The results are stated in this research. Research achievements include the design of a model using Blockchain for electronic medical files, analysis of Block chain's opportunities and challenges, measurement of the components, design and presentation of the model, and prioritizing the challenges of using Blockchain. This research suggests that the use of Blockchain in electronic medical files can reduce extra costs, create a comprehensive system for medical records to avoid additional costs, facilitate access to patient information, and reduce medical errors. The results obtained reveal that the components of immutability and the impossibility of data forgery of patient records (based on data integration in Blockchain) have the most impact on the system. Examination of the challenges reveals that blockchain technology's challenges (low speed, difficulty working with Blockchain, poor integrations between the software for various electronic health records) are of the utmost importance.

The article is devoted to a comprehensive analysis of peculiarities of the content types, which can be placed in social media and Ukrainian Internet media, its differences, types of manipulation, and methods of prevention, perception, and distribution of unreliable information, determination of difference between fact and judgment. The article also analyzes the statistics of social media usage in Ukraine and around the world, using Facebook as an example. Various kinds and types of media existing on the Internet and traditional, conducted a survey of the most popular content using the Starch method, it was possible to identify how a person perceives one content that is placed on different media. The relationship between content type and media type is established. The phenomenon of information restriction, arising as a result of modern algorithms embedded in the Internet companies and social media, their positive and negative aspects and why, therefore, we are deprived of a choice among a wide range of other topics, and learning some other points of view was considered. Examining the origin and meaning of the "Information Bubble" term, the authors propose to use a different term, "Membrane of Relevance", which, in their opinion, is more relevant to the essence of the said concept. The authors propose to use a taxonomy method to determine the impact of content on a particular type of media, which will greatly simplify the content analysis process.
