Building and exploitation of smaller enterprise computer network

The main aim of this work is to describe the gradual building, exploitation, and dissemination of specific enterprise computer network in the Czech company VHL Ltd. The pivotal challenge was not only write down the process, but in practice also the extension of the network by server, the wireless segment, and the connection of two remote computer networks with reference not only to functionality, but also for safety. To achieve the results it was therefore necessary to combine theory with practice. Individual work procedures have been tried, tested and evaluated. In the negative results the whole process had to be repeated several times so. In the bachelor's thesis, there are many instructions on what to do in setting up individual network services as well as ensure their security. The first chapter deals with the theoretical knowledge about LAN and WLAN networks. More closely are describe various standards, network elements and their characteristics, and provided services. The second examines the evolution from the beginnings to the present network. More detailed is describe the enlarging of the wireless network, its construction, security, and testing. The point of third chapter is to give overall view of the extension by network server. It describes the choice of hardware with using multicriterial selection, and the selection, evaluation and installation of the operating system. Subsequently, it deals with hardware and software security of the server and with connection of the remote networks through VPN instrument. In conclusion, there are attended a few words to the potential innovation.
