How to choose a notebook built-in wireless network card

not significantly improved) About compatibility issues. About the compatibility of wireless card, has been very annoying. The main compatibility problem occurs between the router and the NIC and the match between the NIC and the host. In general, if the network card and routers use different brands of the chip, there may be compatibility issues, but this situation is very rare, the current mainly occurs in foreign companies and domestic production equipment. One of the more obvious compatibil

The evolution of Enterprise planning system: from ERP to APs to SCP

Planning is the brain of supply chain operation. For decades, planning has evolved from MRP development to ERP to APs to SCP, from part to overall, from static to dynamic, from enterprise to supply chain. The efficiency of the supply chain depends on planning. Planning is not in place, and any execution is afterwards saved.This is an article by a friend of mine, Ms. Chen. Ms. Chen is Microsoft China's chief Solution architect (manufacturing, energy, retail logistics). He has served as Senior con
