receive the broadcast frame. Broadcast domains and conflicting domains are particularly confusing concepts. We can distinguish them as follows: all devices connected to the two hubs constitute a conflict domain and a broadcast domain; the devices connected to each port on a vswitch without VLAN division belong to different conflict domains (each exchange port constitutes a conflict domain), but belong to the same broadcast domain. Bridging The so-called "bridging" mainly refers to transparent b

%. Therefore, our workshop will introduce you to the RHCE Lab Test process and skills, hoping to help you obtain your own RHCE certificate. RHCE is somewhat different from other MCSE and CCNA certificates because it not only tests the examinee's familiarity with RedHat Linux using multiple choice questions, but also requires a one-day internship, this includes the RedHat Linux installation settings and the Troubleshooting section. The method for apply

today will bring you a new technical introduction series, the name of this series is called "Routing technology in the enterprise's specific application" This is the first article series, "Static routing, default route NAT and static floating routing "I think when you see these nouns, you will not be unfamiliar, whether you are learning Cisco Certification system ( Ccna-ccie) , or to learn the Huawei Certification system (Hcna-hcie) friends may be in

, wireless, voice, data center and so on many aspects, so there are a lot of content need to learn and understand, but lofty high-rise flat, so the basis for the system operation and maintenance is the most important, for the network learning should start from the foundation, network knowledge of the beginning.Network Basic Learning SystemCisco Course System Overview (CCNA), although the knowledge content is not too much, the training cycle generally

wireless is basically from the terminal to a device transmission between the wireless technology, the ultimate backbone or cable or fiber media transmission.So routing switching is the basis of the foundation. This course will build the values of your entire IP network system, so it is recommended to start your network from this course. In-group recommendations: Routing switch learning, you can go to the wireless course, a lot of public CCNA

And the n

router receives a route from OSPF and a route from RIP, it chooses the OSPF route. Because the management spacing of OSPF is 110, the management spacing of RIP is 120. Here's another example: your router receives a route from EIGRP internal, and its management spacing is 90, but you accidentally enter a static route into an IP address where the spacing management address is 1. Then the router uses a static route and does not use EIGRP routing. (☆ Introduction to Programming Network ☆) Finally

Like mathematicians in solving the famous Goldbach conjecture, although there is no final solution to the problem, but in the course of the birth of many famous books related to number theory.Recommended reference BooksAlthough the compilation theory has developed to today, has already had the relatively mature part, but as a university student, must write a kind of compiler like Turboc C,java is still too difficult. Not only is it difficult to write compilers,

is that the school teachers speak more, the basic work is not used, and the teacher did not speak, or speak relatively little, the work is often used more. For example, in C language, the pointers, the structure of these, the school has little or no depth, we do not pay attention to, but to deal with the exam, but the work we need to always deal with them. Did you say you were a good study? This, in part, reflects the fact that there is a serious disconnect between school education and social
