Producer of Android operating system have been trying to offer ways to protect digital data on devices since 1st version of this platform. Development of possibilities of operating system and new technological solutions allows to launch more innovate protections, which are not only more secure, but also very comfortable in everyday usage. This article presents comparison of available solutions, both in terms of the best protection and convenience of usage. The topic of convenience of usage required research to collect information about the most popular configurations among users. The analysis of security level of available locks and obtained results allowed to verify whether owners of devices running Android operating system are properly securing digital data stored in internal memory of their devices.

The article presents the results of a study that will help for user to create a end-user parameters database using other web-sites as the primary source. The main goal of the work is making analysis to obtain information about the user of social networks. Next goal is analysis of the gathering data and the possibility of their use. The experiment was done using two methods of text analysis: parsing and scraping. The results are presented graphically and critical compared to each other.

This article presents time analysis of performance of Windows 10 and Windows 8.1. Presented research was mainly focused on performance comparison of mobile device system elements which are relevant from end user point of view like main processor, RAM and mass storage throughput, image generation speed by the graphics processor and access time to devices. In order to measure the performance of the above elements a mobile benchmark application was created. The hypotheses set in the article have been verified and partially confirmed.

The aim of the article is to compare the tools for automating user interface tests on the example of Sikula and AutoIT. The conducted research has focused on the time of testing scripts, their complexity, ease of maintenance and reliability. For the purposes of the study, an application in C # was created and several representative automatic tests were written in each tool.

Comparison of efficiency is not a trivial phenomenon because of disparities between different database systems. This paper presents a methodology of comparing relational database systems in respect of mean time of execution individual DML queries containing subqueries and conjunction of tables. The presented methodology can be additionally accommodated to studies of efficiency in a range of database system itself (study of queries executed directly in database engine). The described methodology allows to receive statement telling which database system is better in comparison to another in dependency of functionalities fulfilled by external application. In the article the analysis of mean time of execution individual DML queries was performed.Two research hypotheses have been put forward: "Microsoft SQL Server database system needs less time to execute INSERT and UPDATE queries than Oracle database" and "Oracle database system needs less time to execute DML queries with binary data than SQL Server".

The paper describes results of the possibility analysis of environmental monitoring and detection threats with the Arduino platform. Sensors compatible with Arduino enabling environmental monitoring were used to conduct research. The research consisted in monitoring environmental parameters, monitoring among others air temperature and humidity, sound level or gases harmful to health., Capabilities of the platform have been analyzed based on the obtained results.

The article compares two modern integration platforms used in production and test environments. These are, a free integrity solution WSO2 data bus and OSB bus, called Oracle Service Bus, which is a commercial software. The tests that were carried out on the abovementioned buses and results were discussed. In addition, a comparison of results with conclusions that were drawn after the tests was attached.

Automation tests are used for verification of functionality of developing applications. The performance of automation tests written in HP UFT and Selenium WebDriver was compared. There were created 3 tests for both technologies that were executing the same tasks. According to the obtained results, it was concluded which technology is a better choice if the time efficiency of tests execution is important.
