I am a computer science and technology major, engaged in a wide range of networks. Basically, anyone majoring in computer can engage in networking, but it depends on whether you have a solid network foundation. The foundation is the most important, such as many important protocols such as TCP/IP, which must be mastered. There are also some routing aspects, and network operators have a wide range of knowledge. General network operators do some things about the establishment of LAN topology, the setting and configuration of servers and routes, network maintenance and network security.

Let me introduce the company with the strongest online training in the world today, that is "Cisco". Cisco has done everything in network technology. Now Cisco network engineer training is available in large and medium-sized cities in China. Cisco network engineer certification is divided into the following categories:

Authentication system:

CCIE cisco certified Internet Work Expert

CCDE cisco certified design expert.

CCNP cisco certified Senior Network Engineer (Cisco Certified Network Expert)

CCDP cisco certified Senior Design Engineer (cisco certified Design Expert)

CCIP cisco certified Senior Internet Engineer (cisco certified Internet

Work major)

CCSP cisco certified security expert.

CCVP cisco certified Senior Phonetic Engineer (cisco certified Phonetic Expert)

CCNA cisco certified network assistant

CCDA cisco certified Design Assistant.

These certifications are necessary to pass regular training exams. Cisco pays attention to operation, but the exam content is mainly in English. Ccna is easier to test, but the higher the level, the more difficult it is to test. It is understood that only a few thousand people in ccie have passed the exam.

If you are interested in the network, you can take part in the training, so that you can learn the real network professional technology.

I'm a freshman majoring in computer science this year, and now I'm attending training at Cisco. . ITAA is really good. I ask everyone to master the learning content and operate it every day. I feel that I have improved a lot. Thank you.
