Purchase of network card: According to statistics, the vast majority of local area networks use Ethernet technology, so we focus on the Ethernet network card as an example to talk about some Things you should pay attention to when purchasing a network card. When purchasing, you should pay attention to the following key points:
Application fields of network cards: Ethernet network cards include,,,/and Gigabit network cards. For large data volume networks, the server should use a Gigabit Ethernet network card. This network card is mostly used for the connection between the server and the switch to improve the response rate of the overall system. However, network cards, network cards, and network cards are commonly purchased and commonly used network equipment. The prices of these three products are not much different. The so-called / adaptive means that the network card can automatically negotiate with the remote network device (hub or switch) to determine the current available rate. For common file sharing and other applications, the network card is sufficient, but for possible voice and video applications in the future, the network card will be more conducive to the transmission of real-time applications. In view of the existing foundation of the technology (such as previous hubs and switches, etc.), the usual workaround is to purchase/network cards, which not only helps protect existing investments, but also facilitates further expansion of the network. In terms of overall price and technology development, it will still take some time for Gigabit Ethernet to reach desktop computers, but the era of Gigabit Ethernet is gradually gone. Therefore, for small and medium-sized enterprises, /network card should be the first choice when purchasing.
The switch can transmit data between multiple port pairs at the same time. Each port can be regarded as an independent physical network segment (note: non-network segment). The network equipment connected to it enjoys all the bandwidth by itself without competing with other equipment. When a node sends data to a node, node B can send data to the node at the same time, and both transmissions enjoy the full bandwidth of the network and have their own virtual connections. If b's Ethernet switch is used here, then the total traffic of the switch at this time is equal to bb, and when using b's shared B, the total traffic of one B will not exceed b. In short, a switch is a network device that is based on address recognition and can complete the function of encapsulating and forwarding data frames. The switch can learn the address and store it in the internal address table. By establishing a temporary switching path between the originator and the target receiver of the data frame, the data frame can directly reach the destination address from the source address
Switch The transmission modes include full-duplex, half-duplex, and full-duplex/half-duplex adaptive
Full-duplex of the switch means that the switch can also receive data while sending data, and the two are synchronized. It seems Just like when we talk on the phone, we can hear each other's voice while talking. All switches support full duplex. The advantage of full-duplex is small delay and high speed.
