NIC different classification: According to the different network technologies, network adapters also have different categories, such as ATM adapter, token ring and Ethernet network adapters and other adapters. There are about 80% of the local area network are using Ethernet Network Adapter according to statistics. Ethernet Network Adapter is specifically designed according to the objects of the working characteristics of different service devices, so it is more expensive, but the performance is good.
There are 10M, 100M, 10M/100M and Gigabit LAN products of RJ45 Ethernet Network Adapter. For large data network, the server should use Gigabit RJ45 Ethernet Network Adapter which are used for connections between servers and switches to enhance the response rate of overall system. Peope are often purchasing the 10M, 100M and 10M/100M Ethernet Network Adapters which is used in network equipment, and the price of these three is very simliar. The adaptive ability of Ethernet Network Adapterrefers to the so-called 10M/100M card with remote network device (hub or switch) auto-negotiation to determine the current available rate is 10M or 100M. For the usual file sharing applications, 10M Ethernet Network is enough, but the potential for future voice and video applications, 100M adapter will be more conducive to the transmission of real-time applications. In view of the foundation 10M technology already have (such as previous hubs and switches, etc.), the usual solution is to buy 10M/100M Ethernet Network Adapter. Ethernet Network not only protecte the existing investment, but also conducive to the further expansion of the network. It will take some time when Gigabit Ethernet to the desktop machine accoring to current price and technology development, but time has gradually gone of 10M. So to the SMEs, 10M/100M adapter should be the preferred procurement.
