Increasing of security and performance of local area networks

To reach the newest and accurate information has become fairly important in recent years. Computer and enformatik science progress continually and very fast to facilitate obtaining the information that is necessary in a short time. Networks should be established to use information and sources more effectively. These are the structures that enable users to share the existing information and sources available on the separate computers, and to communicate. The power of networks depends on how accurately this structure is used. Today, the use of local area networks is inevitable where computers are used. Providing continuous information has become more important than sharing the sources available on the networks. Availability and proficiency of topology adjustment of the connection hardware, determination of the features of the protocols used and the factors having effect on the security and performance should be precisely known to provide the users with constant share of information. This study focuses on the brief explanation of structures used in the computer networks and the recommendations on the improvement of the networks.
