The existence of a faculty is based on two necessary parts: the professors and the students. During the years the last one have not been organized so, to be able to defend their rights with all the power necessary. In the 2001 a group of young enthusiastic students took the decision to organize the students from the Faculty of Automation, Computers and Electronics. So started OSACE, the student organization. One of the most important parts in a student organization and in fact in a very large group of people is the information. Having this in mind I decided to make a student network in the office of the Student Organization (OSACE) and also a web page containing the information necessary for the students. The web page also contains a forum for all the discussions needed. Now after a hard work all these exist. In the OSACE office there are 3 computers with access to Internet opened to all the students from Faculty of Automation, Computers and Electronics. One of them is server where it is also the web page with the forum. It also exists a separate group of discussion where now are enrolled almost 70% of our students.
II. COMPUTER NETWORKS
New business practices are driving changes in enterprise networks. Employees at corporate headquarters and in worldwide field offices, as well as telecommuters in home offices, need immediate access to data, regardless of whether the data is on centralized or departmental servers. Enterprises such as corporations, agencies, schools, and other organizations that tie together their data communication, computing, and file servers need:
- interconnected LANs that provide access to computers or file servers in other locations
- high bandwidth onto the LANs to satisfy the needs of the end users
- efficient WAN(s) to interconnect the LANs
To improve communication with partners, employees, and customers, enterprises are implementing new applications such as electronic commerce, videoconferencing, voice over IP, and distance learning. Businesses are merging their voice, video, and data networks into global enterprise networks as shown in These enterprise networks are viewed as critical to the organization's business success.
Enterprise networks are designed and built to support current and future applications. To accommodate increasing requirements for bandwidth, scalability, and reliability, vendors and standards bodies introduce new protocols and technologies at a rapid rate. Network designers are challenged to develop state-of-the-art networks, even though what is considered state-of-the-art changes on a monthly, if not weekly basis.
Dividing and organizing the networking tasks into separate layers/functions allows new applications to be handled without problems. The OSI reference model organizes network functions into seven categories, called layers. Data flows from upper-level user applications to lower-level bits that are then transmitted through network media. The task of most wide area network managers is to configure the three lowest layers.
