Business networks are undergoing a series of transformations, due to technological advances, but also to the change in the IT approach, which brings them closer and closer to being the true drivers of business objectives. 

Beyond the flexibility and dynamism that networks now require in their implementation and administration, the proliferation of the use of personal devices in companies has required the opening of networks to this phenomenon, as well as a growth in the reach of networks wireless, and the restructuring of access and security policies. Similarly, delivery times are getting shorter, which leads to seek greater automation of functions and simplification of network administration, often in virtualized environments or using cloud platforms. Today, the internet is, for many, an almost indispensable tool for working, interacting with others and even planning different types of activities.

In its fair measure, its use is positive, since it is used as a means to facilitate and make different aspects of everyday life much easier. However, there are those who cannot live without social networks. Such is the addiction that they modify many situations, routines and even their interpersonal relationships.

Purpose of Network Specialist

The course is available as part of the Cisco Extreme Network Specialist Academy international program and involves obtaining international certificates. The training is conducted at one of the leading Russian Networking Academies of Cisco under the guidance of Cisco certified world-class instructors. The curriculum is built according to the traditional “from simple to complex” scheme for Cisco academy courses, from the very beginning setting solid theoretical ground on the basis of which practical skills are given. Electronic course materials include many laboratory works that allow you to have a versatile look at the principles and technologies being studied. Access to the course materials can be obtained using a personal smartphone, tablet, laptop or desktop computer.


Training on the CCNA Routing and Switching course allows students to effectively prepare for the exam for obtaining the CCNA (Cisco Certified Network Associate) industrial certificate - certificate No. 1 of a specialist in the field of network technologies.

The goal of the course is to train a network specialist who can serve real corporate networks, so this program will be a good start for those who are looking for the opportunity to quickly master the practical skills of a network engineer without special training in the field of information technology.

From the previous video we learned about the basics of the network, and today we’ll talk about the OSI model and the TCP / IP model. When I speak of models, I mean nothing more than a set of rules, or a set of standards. You may ask, why do we need a set of rules or standards in the computer industry? To understand this, we need to learn a little about the history of the computer industry.

Not so long ago, a fierce battle took place between IBM and Digital Equipment Corporation (DEC) over which of them is a leading computer manufacturer. But there was a problem. Both of these manufacturers produced computer equipment that was incompatible with each other. That is, if you bought an IBM computer, then you had to purchase a monitor, printer and everything else from IBM as well. Similarly, if you bought a device from DEC, you had to buy all the accessories and other devices of the same manufacturer in order to be able to use them.

There were many companies that bought equipment from both manufacturers, so that, for example, there were IBM computers in the accounting department, and the marketing department was equipped with DEC computers. As a result, these devices could neither communicate nor share information with each other. Thus, the absence of a single standard did not allow computer technologies to move forward. This happened around the time when the International Standards Organization, known as ISO, came to the conclusion that there was a need to create a common computer standard. ISO has developed OSI - the Open System Interconnect, or OSI reference model. Around the same time, a competing standard was created - the TCP / IP model, which was promoted by the Department of Defense. The TCP / IP model is more like a stripped-down version of the OSI model and, due to its relevance, has become an industry standard.
