A Network switch is a type of network device used to connect multiple devices in a local area network (LAN). It can receive and forward data packets through physical or wireless interfaces, sending data packets from the source device to the target device. Network switches can identify and forward packets based on MAC addresses so that data can be accurately transmitted to the target device.

According to the website of the National Development and Reform Commission, the National Development and Reform Commission recently deployed price departments at all levels to strengthen market price supervision during the 2013 New Year and Spring Festival and to regulate the market price order. In the notice, the NDRC stressed in particular that “we must focus on the promotion behavior of large e-commerce operators.â€
According to the NDRC, it is necessary to continue to carry out rectification of the price order in the retail trade, and to inspect large-scale and influential supermarkets, department stores, shopping malls and other commercial and retail enterprises, focusing on the promotion of large-scale e-commerce operators. Strictly investigate and prosecute the illegal sales price higher than the original price, not fulfilling price commitments, and concealing price attachment conditions, and standardize the promotion activities such as price reductions, discounts, rebates, gifts, etc., to create a good consumer environment.
The notification requires that the competent price departments at all levels should strengthen the monitoring and supervision of the daily necessities of grain and oil, liquefied gas, meat and eggs, and milk vegetables, especially basic vegetable varieties, and the local residents' daily consumption of specialty foods, and focus on investigating and managing the use of fabricated products. Spread prices, reluctant sellers and other means to drive up prices, and the use of monopoly sources, mandatory agency, negotiate alliances and other means to manipulate prices, actively prevent and properly respond to abnormal market price fluctuations, and maintain normal market price order.
In addition, it is necessary to strengthen the supervision of the tourism market price during the holiday season and investigate and punish the behaviors of tourism operators in the use of false or misleading prices such as “zero negative tour fees†and “special price†to promote, recruit and organize tourists, and provide services. Disguised price increase or price fraud, build a good tourism market environment.
A network switch usually has multiple ports, each of which can connect to a device, such as a computer, server, printer, etc. When a device sends a packet, the switch forwards the packet to the corresponding port according to the MAC address of the target device, thus achieving communication between devices.
The network switch can also divide the virtual local area network (VLAN) into multiple logical subnets, so that different devices can communicate independently on the same physical network, improving network security and performance.
In short, a network switch is a network device used to connect and forward packets, which can realize communication and network management between devices. It is an important part of building local area networks and enterprise networks.
