The PC computer has Ethernet or wireless network card to access the Internet.
The network device is a device responsible for protocol conversion and message forwarding, such as a wireless Access Point (AP), and when our mobile phone accesses the AP through WiFi, the AP is responsible for converting a wireless message between the mobile phone and the AP into a wired message from the AP to a network switch. In addition, switches, routers, repeaters, base stations, etc. are all network devices, and are mainly responsible for forwarding information.
Several major wireless communication technologies currently include: wireless mobile communication technology, wireless local area network communication technology, personal wireless local area network communication technology and interphone wireless communication technology, wherein the wireless mobile communication technology comprises GSM, GPRS, 3G and 4G, is currently the most mainstream mobile communication technology, a mobile phone is accessed to a base station through authorized frequency, and the base station is accessed to a core network through optical fibers. The distance between the mobile phone and the base station can reach tens of kilometers. Cell phones, base stations, core network systems, BOSS systems, etc. require operators to build and operate infrastructure, users also require costs for using the network, and the technical standards are dominated by the standard alliance. The wireless local area network communication technology, also called as WiFi technology, works in an ISM frequency band, is used as extension of wired network access, can solve the problem of short-distance wireless communication, and the AP is used as a gateway to complete protocol conversion, and the technical standard is formulated by an IEEE802.11 working group. The personal wireless local area network communication technology works in an ISM frequency band, mainly uses a Bluetooth technology, and realizes short-distance wireless transmission.
