Desktop computers and notebooks - expandability and architecture
Jančík, Jakub ; Jandoš, Jaroslav (advisor) ; Čech, Milan (referee)
This bachelor thesis compares expansion possibilities and architecture of desktop PCs and notebooks. It analyses different types of computers for personal use, desktops and notebooks, it categorizes them and analyses contemporary available on the Czech market. The goal of this thesis is to analyze expansion possibilities and also analyze the issue of using notebooks as desktop replacements. In relation to notebooks expandability this thesis analyses docking stations and possibilities that arise from their using. The thesis consists of five major sections, where chapters about desktop PCs and notebooks contain theoretical knowledge which are basis to a comparison of desktops and notebooks. As a possible solution of expansion of notebooks should be considered possibility of docking this is analyzed in a separate section. Conclusions are verified by a survey which is aimed at contemporary using of computers and their expandability with focus on docking stations.

Disk arrays, use in small business
Sládek, Petr ; Jandoš, Jaroslav (advisor) ; Čech, Milan (referee)
Thesis aims to examine issues of disk arrays and their deployment in small business. It will focus not only on theoretical description of technologies, but also to carry out practical tests and performance characteristics, conduct or analysis in the field of non-standard situations. To describe the theoretical background of the problem, I used the available literature and web resources. The practical test then served on borrowed Adaptec RAID controller and on the motherboard Asus. Given the rapid evolution of SSD drives in my test also included the performance tests of this device. Recent work also includes a survey among small business company, which serves to assess the various criteria for evaluation. Currently, it is very difficult to find specific tests of controllers or less usual levels of disk arrays, which many manufacturers use. The results can therefore serve as a valuable source of information for users seeking the best solution for their needs. They may be useful as theoretical tests and service experience. From the previous lines then follows the structure of work. The first part is purely theoretical, and aims to acquaint the reader with problems. The second part focuses on the synthetic and practical test of arrays and SSD and is accompanied by a description of the behavior of various configurations of hard disk failure. The last two parts evaluates the results, the criteria are partially dependent on the results of the survey, which can be found in the last part.

Analysis of mobile operators’ services
Pávek, Jan ; Jandoš, Jaroslav (advisor) ; Ćech, Milan (referee)
The theme of this bachelor thesis is the analysis of mobile operators' services. The first part is to map technologies for operation of mobile networks. Furthermore, these technologies will be assigned to particular Czech mobile operators. For each technology I will introduce the actual coverage. The acquainting the reader with the technological aspect is followed by an analysis of the offered services. I will take into account all Czech mobile operators. It concerns companies Telefónica O2 Czech Republic a.s., T-Mobile Czech Republic a.s., Vodafone Czech Republic a.s. and Mobilkom a.s. I also chose a foreign mobile operator -- T-Mobile Deutschland. At the end I make a practical test of selected technologies for mobile data transfer. The aim of this study is to compare the Czech mobile operators in technological point of view and also in offered services aspect. I will concentrate on supply to end consumers. Services are divided into categories: prepaid cards, voice flat-rates tariffs and mobile broadband tariffs. Within each category are made recommendations for specific customer groups. Analysis of the German mobile operator is to confront the Czech mobile operators with foreign countries. In a practical test, I verified the actual parameters of the recently launched 3G network of mobile operator Vodafone. Overall, the work could help in the orientation of technologies for mobile networks and should facilitate the selection of appropriate mobile services, including the choice of mobile operator. For elaboration of the subject I used technical literature dealing with mobile communications. Presentation of mobile operators was held at the base of their press releases and selected articles on the Internet. Current price lists of mobile operators have been the source of information for analysis of mobile services. Practical test was executed with equipment borrowed by Vodafone Czech Republic.
