The modern education system, one way or another, aims to form students' abilities to work with information. It is no coincidence that the prior areas of education development pay special attention to form skills of information processing, which later becomes the mainstay of professional activity of graduates in the information society, a necessary component of information culture. In such circumstances, students will acquire the necessary knowledge to express themselves creatively, learn to evaluate the accuracy of the information, develop critical thinking, and distinguish information and knowledge.
Local networks are common in the education field. Most schools and other educational institutions have computers connected to a local network. At the same time, modern technologies allow to connect even the computers that are on different continents, and not only in the same room or building. Numerous educational institutions have branches in different countries, with computer connected via local network. Moreover, local area networks can connect computers from different colleges or universities.
Using Internet, any student can get public access to education materials that can be presented in the form of simple textbooks (e-text), as well as in the form of complex interactive systems, computer models of virtual learning environments, etc. The number of users and information sources of Internet is continuously increasing. In addition, there is a constant quality of telecommunications services improvement. Because of this, not only companies and organizations operating in the economic and other fields have a high-quality access to the Internet, but also educational institutions.
Many systems are susceptible to vulnerabilities that can take full control of critical resources (e-mail systems, network equipment management and others). Critical vulnerabilities are often associated with the use of outdated versions of software and operating systems.
Studies have shown that the modern corporate networks are quite vulnerable to attacks from internal and external intruders. The ability to access the critical resources of most examined systems leads to the conclusion about the necessity of the information security measures improvement, particularly in the area of password policies, web application protection, providing regular security updates and protection of privileged accounts. For safety deficiencies early detection, system administrator should regularly conduct security analysis, including the form of penetration testing.
A Campus Area Network (CAN) is a computer network that links the buildings and consists of two or more local area networks (LANs) within the limited geographical area. It can be the college campus, enterprise campus, office buildings, military base, industrial complex. CAN is one of the type of MAN (Metropolitan Area Network) on the area smaller than MAN.
The Campus networks usually use the:
- LAN technologies,
- such as Ethernet,
- Token Ring,
- Fiber Distributed Data Interface (FDDI),
- Fast Ethernet,
- Gigabit Ethernet
- Asynchronous Transfer Mode (ATM).

Campus network can be additional to the set of wireless connections, connect several buildings to the same network, but it's not the same thing. A campus network should be broad enough to cover a large territory, while the point-to-point access simply distributes a separate network within the territory of several buildings. Project Athena at MIT and Stanford University Network at Stanford University are the most well-known networks. Athena was launched in 1983 and it still works. It’s primary purpose was to share experience, code and ideas among students, to found a base of knowledge for the future generations and to develop educational tools. This project influenced the development of instant messaging, online help systems, improved client–server model of distributed computing, developed Kerberos protocol for encrypted authentication and authorization and has many other functional and system management advantages. Some of Athena architecture design features are used beyond MIT, for example in Iowa State University and North Carolina State University.
All networks designed with ConceptDraw DIAGRAM are vector graphic documents and are available for reviewing, modifying, and converting to a variety of formats (image, HTML, PDF, MS PowerPoint, Adobe Flash or MS Visio).

A network diagram represents the set of computers and network devices and the connections among them. This scheme can be developed for any institution or establishment. To illustrate this concept let’s take for example, a hotel network topology diagram or a school network diagram. These diagrams depict access points, servers, workstations, firewalls and another equipment needed to provide a network.
On this masterpiece drawing one will see a simple scheme a of connecting computers together. Such form of connecting can be applied for a hotel, guest house, bungalow, hut or something else. This diagram shows the images of the real LAN components. So, it represents a physical category of a network construction. It looks similar to a star - so this network configuration is named a star topology. The typical feature of this construction is a center point - usually it is hub, or router. The rays of this star means network connections. Computers, peripherals and other network details are placed on the ends of the star rays.

A list of parameters on which networks differ is very long. A large network with a range up to 50 kilometers is called metropolitan area network (MAN), and this type of network can include several local area networks. Metropolitan networks in their turn connect into global area networks.
Here you will see a Metropolitan Area Network (MAN). This is an extensive network which occupies a large territory including a few buildings or even the whole city. The space of the MAN is bigger than LAN, but lower than WAN. MAN comprise a lot of communication equipment and delivers the Internet connection to the LANs in the city area. Computer and Networks solution for ConceptDraw DIAGRAM provides a set of libraries with ready-to-use vector objects to design various kinds of computer networks.

As restaurant industry is growing rapidly nowadays, researches show that almost half of the adults have worked in a restaurant or a cafe. Moreover, many of them dream to start their own someday. Unfortunately, it takes a lot of time to write a business plan and to find a great location, although some know how to create a restaurant floor plan in minutes or how to plan budget effortlessly. Hiring employees can also cause a lot of headache, but this is crucial for further success, because every guest comes to restaurant for a good service and delicious food. It is also worth noting that restaurant concept is also important, because it defines target audience and influences the menu.
This diagram represents the floor plan of an ongoing sports-theme establishment - restaurant, cafe, or other food service. A number of widescreen monitors installed along the perimeter provide visitors the opportunity to follow the course of a match from anywhere in the dining room of restaurant or cafe. The most of sports fans believe that food and alcohol is a big part of any sports show. That is why the dining room takes the most space - almost 60% of the total establishment space. Nearly all sports fans consume beverages while watching sports - beer, soda or water at least. Thus, the restaurant floor plan designers added a large lavatory there. Moreover, project developers considered unnecessary the gender division of such delicate place - perhaps they guess that only men are watching football, or believe that alcohol will eliminate the most of gender differences.
