network topology advantages and disadvantages

DatabaseType Characteristics Advantages Disadvantages relational databaseSQLite, Oracle, MySQL 1, relational database, refers to the use of a relational model to organizeDatabase of data;2, the most characteristic of relational database is the consistency of affairs;3, in simple terms, the relational model refers to the two-dimensional table model,A relational database is a data

support the "IP Tunneling" (IP Encapsulation) protocol, the server may only be limited to some Linux systems. Iii. Direct routing mode (VS-DR) Principle: Both the Load balancer and RS use the same IP external service, but only Dr responds to ARP requests, all RS to the ARP request of itself this IP is silent that is to say, the gateway to the service IP request all directed to the DR, and Dr received the packet according to the scheduling algorithm, find the corresponding RS, To change the d

complexity of the application index-ready file is O (n).C) Poll use Nfds to specify the maximum number of file descriptors and events to listen to, this number can reach the system agreed to open the largest file description of the descriptor. That is, 65535.D) can only work in the LT mode.3) Epoll:A) epoll the file Description descriptor and events of the user's booklet into the event table in the kernel. Provides a stand-alone system call Epoll_ctl to manage user events, and epoll the way cal

such a structure, there is no need for another interconnected device. Instead, it is directly connected through a bus, so the cost of networking is low; 2) because each node in this network shares the bus bandwidth, the transmission speed will decrease as the number of users accessing the network increases; 3) Flexible expansion of network users: you only need t

that the server and client exchange for information when they connect. Each of these technologies has advantages and disadvantages. Exactly which technology you use depends on the specific needs of the WEB application you are developing. The Web 2.0 feature package provides support for these protocols on both the server side and the client, helping to simplify WEB development. The center of Figure 1 is a

Research on topology control of wireless sensor network based on energy levelabsrtact: in the planning and design of wireless sensor network, it is the first important problem to reduce the energy consumption of the nodes, prolong their working time and maximize the life cycle of the network. This paper designs a

Facebook: an innovative data center network topology Facebook aerial bird chart in the data center of alitabane artuna Facebook's data center receives billions of user requests every day. As the company continues to add members and introduces new features, the number of requests continues to increase. This is basically a good thing for Facebook, but it is a challenge for Facebook's

Wireless network interfaces have many advantages. They do not need to be covered by wireless network signals. Some people say that wireless network interfaces do not need Wireless LAN to access the Internet. Can this happen? Next we will analyze the disadvantages of wireless

The IP address of IPv4 has come to an end, so it is extremely important to use the IPv6 network protocol. So is IPv6 only used to relieve the Internet address pressure? Of course, the answer is NO. So what advantages is it worth using? Now let's take a look at how it is said in the article. (1) huge address space The source and target addresses of IPv6 are both 128-bit (16 bytes) and can provide IP addresse

the subnet. It can work with DHCP, and does not need new routing protocols. Fast Convergence: With this feature, you can use hardware to assist in failed operations on entries in the information flow to respond to route failures and changes in the routing topology. Recovery capability: Provides the advantages of HSRP, but does not require additional configuration. With this feature, when the primary router

Therefore, it also has its unique advantages when applied to network management. Transparency: you do not need to modify the endpoint system or rename the subnet. It can work with DHCP, and

In modern society, the role of information has been paid more and more attention. The international Internet is developing at an incredible speed. For the first time, people are facing the ocean of information. The international Internet provides new communication methods. The emergence of the Internet has allowed information transmission to go beyond the limitations of time regions, making it easy and convenient to transmit information. As a new form of media, the Internet has obvious

The state of the art of Non-linearity was to use ReLU instead of sigmoid function in deep neural network, what is the Adva Ntages? I know that training a network when ReLU was used would be faster, and it's more biological inspired, what's the other A Dvantages? (That's, any disadvantages of using sigmoid)?Best answer in Stackexchange:Additional major benefits of
