Building and use of small computer networks
Loukota, Jan ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
This work deals with design of home computer network. It is divided on theoretical and practical part. The theoretical part is written about technologies used in practical part name-ly computer networks, topologies, active and passive elements, RAID arrays, network at-tached storage and wireless technology. The practical part is further divided to four sub-parts. First deals witch description of current state of rebuilding network. It involves meas-uring of speeds and pointing out of it's shortcomings. The second sub-part is about plan-ning new state of network and choosing new components. The third sub-part deals with installing and configuring components. The last sub-part is testing of the new state. The end of this work is dedicated to evaluation of rebuilding process and fulfilment of de-manded goals.

Malá, Kateřina ; Sigmund, Tomáš (advisor) ; Vaněk, Jiří (referee)
This thesis addresses the issue of ethics on the Internet. The first part focuses on a brief history of the development of ethics and ethical principles used even today. The second part is devoted to information ethics, which is an integral part of the Internet, since it deals with the creation, dissemination, transformation, storage, search, use and organization of information, and also deals with specific standards, codes and principles that were created either specifically for the Internet or are now an integral part. The third part is devoted to valid Czech and European legislation in the field of information work in various media, including on the Internet. The final section is devoted to the evaluation of the current situation of ethics on the Internet, where they described the problems with which we meet today. Such problems are violations of copyright law, whether piracy or plagiarism, threats associated with Internet communications, kyberstalking, cyberbullying, kybergrooming or activity on social networks. In addition, problem situations are mentioned online trading, which are currently controlled by many associations, consumer protection or influence of the media and advertisements, and incessant problem of censorship.

Possibilities of usage of social networks in business practice
MARTÍŠEK, Petr
Communication is the basis of the human society; Internet has contributed to that in recent decades. Mass interconnection of people by means of social networks is a phenomenon of recent years. The purpose of my thesis was to map the situation in the area of the use and development of social networks, advantages and disadvantages in the area of communication, their development and their future. In my analysis, I also dealt with possible ways of using these networks in business. Two surveys have become the basis of my evaluation. The survey in the field of consumer market evaluated the extent and orientation of the use of social networks by people in the Czech Republic; the other one concentrated on business entities and mapped the way how companies use social networks for communicating with customers and general public.

Possibilities and conditions of increasing the competition abilities of companies by social networks
Jaščur, Miroslav ; Molnár, Zdeněk (advisor) ; Měsíček, Libor (referee)
In this diploma thesis I deal with possibilities and conditions of increasing the competition abilities of companies by social networks. In the theoretical part I target essence and history of formation of social networks. I also looked at basic principles of their behaviour and discribed their sources of income. In the practical part I used various statistics of popularity and I chose social networks which can offer the highest increase of share at the market to companies which are interested. Consecutively I created analysis of penetration of chosen social networks to czech bussiness environment and I gave an objective account on this issue using case studies of the companies. At the end I suggested principles for successful managing of social networks comunity which should lead towards the increase of the ability to compete. The thesis will not be the most extensive one analysing social networks but it is a good summary of theoretical and practical knowledge and will serve as a very good inspiration for deeper research of with possibilities and conditions of increasing the competition abilities of companies by social networks.

Redesign of information systems in multimedia laboratory(GML) on VSE
Burda, Adam ; Horný, Stanislav (advisor) ; Krsek, Libor (referee)
This paper aims to describe and propose solutions to problems impairing the functionality of the Prague School of Economics' Graphics and Multimedia Laboratory (GML). The problems to be solved arise in the current information technology devices, more specifically in data back-up, usuitable hardware and lan connection as well as missing software. Finally, the paper discusses the idea of puchasing devices to be used outside the GML. The multimedia laboratory is concerned with issues relating to graphics creation and video adjustment. The solution put forward in this paper proposes using specific hardware designed for editing and graphics applications. While an effort is made to seek a multiple solution, the proposed adjustments require purchasing new hardware and software which are innovative if rather costly. Financially demanding as those are, both the optimal and the more budget-friendly options are introduced. Finally, an overview table summarises the costs, supplemented by detailed calculations. The solutions proposed are based on generally accepted procedures. These are modified in view of the author's experience of network administration and devising specific coputer systems.

Methods of protection against eavesdropping and snooping in digital networks
Pokorný, Tomáš ; Šalamon, Tomáš (advisor) ; Štorková, Veronika (referee)
The aim of this work is to provide a comprehensive overview of eavesdropping and snooping in digital networks, describe possible threats and show technological and organizational precautions against them. The first chapter introduces the reader into the topic and shows all the main threats. The second chapter describes technological precautions with the emphasis on data flow. The first part of this chapter explains the terminology. Next part tries to solve the security of each type of a communicational channel followed by the virtual private networks issues, physical networks and the risks of encryption. The third chapter analyses organizational issues with the emphasis on legislation. Precautions in this chapter make the technology from the previous chapter more effective. The fourth chapter uses the findings from previous chapters and tries to secure a company in all its complexity. This allows the estimation of total cost. The practical part of this thesis should serve for companies with already developed infrastructure who want a transparent solution that would protect them from eavesdropping and data thefts.
