Correction: wireless AP = wireless switch.
1. Switch: usually refers to the device that sends and receives information in the second layer of the network, that is, packet exchange based on the mac address.
2. Router: is a device that works in the third layer of the network, which is to forward data based on the IP address.
3. wireless and wired: is the network side of the device (such as computers) and the network device "connectivity"
4. connectivity combined with the formation of network devices: switch with wireless access and router with wireless access.
5. Often routers with wireless also include wired switched access, so they are referred to as wireless routers.
6. The vast majority of switches with wireless do not include wired access and can be placed in hidden places such as ceilings and floors. In its effective signal range for wireless access, called Aess Point, referred to as AP, in fact, the word wireless is redundant, AP means wireless switch.
7. You can liken an AP to a cellular company's base station, which serves your cell phone, and a wired phone, which has to be connected to a switch at the telephone office.
What is the difference between a wireless AP and a wireless router or wireless switch?It should help you! Wireless AP to speak in layman's terms is simply to turn the wired signal into a wireless signal, generally only a network port; wireless router can be a proxy for the Internet can also do NAT so that you can use an account or IP multiple people on the Internet, that is, in the ordinary router on the addition of the wireless module. Wireless switch and wireless AP is almost the same, not commonly used, you can switch on the wireless module can be said to be a wireless switch.
What is the difference between the so-called wireless switch and wireless router?First of all, the home are generally to choose the router is the main, the switch is generally not used, and secondly, the switch only provides data exchange and does not mention the allocation of resources and other functions; furthermore, you buy a wireless router, the network operator will provide you with a broadband line to access the wan port of the wireless router, and then the desktop cable into the router's lan port, and then log on to the wireless router for the link setup, according to the different services provided by the network operator set up the wireless router. Network operators to provide different services to set up the dial-up link as an example (PPPoE) This time, first enter the user name provided by the network operator, and the password, and then set up a wireless link here to set the security mode, in which to enter the password, and then use your laptop to search for a wireless network, and when you find the network to enter the password you just set up can be used at the same time.
The difference between a router and a switch: a switch is mainly to realize that everyone has access to the Internet through a network cable, but everyone has access to the Internet through separate dial-ups, each using their own broadband, and everyone has access to the Internet without any impact, even if other people are downloading, and there is no impact on their own access to the Internet and all the computers that are using the same switch are on the same local area network (LAN). Router than the switch has a virtual dialing function, through the same router to access the Internet computer is **** with a broadband account, the Internet between everyone is the impact of each other, for example, a computer in the download, then the same router on the other computers will be very obvious to feel the Internet speed is very slow. The computers on the same router are also on a LAN.
A switch is a switched hub. The switch and the hub are roughly the same in terms of network performance. The biggest difference is that each port on the switch has an exclusive bandwidth and data exchange capability, which allows the network to transmit a larger amount of data at the same time, while the hub has all the ports to enjoy a bandwidth.
A router, also known as a gateway device, is used to connect multiple logically separated networks, where the so-called logical network represents a single network or a subnet. When data is transmitted from one subnet to another, it can be accomplished through the routing function of the router. Therefore, the router has to determine the network address and select the IP path function, it can be in a multi-network interconnection environment, the establishment of a flexible connection, available completely different data packets and media access methods to connect a variety of sub-networks, the router only accepts the source station or other router information, belongs to the network layer of a kind of interconnection equipment.
Wireless router as a wireless AP (wireless switch) use, how to set upIn the existing wired network to achieve wireless functionality, you can use the wireless router as a wireless AP (wireless switch) to use the setup steps are as follows: 1, stand-alone connectivity and log on to the wireless router, change the LAN port IP address of the wireless router, to avoid conflict with other devices in the intranet; turn off the wireless router DHCP function, and then set up the wireless router. DHCP function of the wireless router and restart; 2, the wireless router 1/2/3/4 port and wired network router or switch wired connection; 3, the operation of the network in the wireless network card to connect to the wireless router; 4, configure the wireless network card network parameters (automatic access or manual configuration, manual configuration parameters and wired consistent); (easy to use network )
wireless router and wireless switch The difference betweenwireless routers and wireless switches are as follows:
One: wireless routers than wireless switches more than a virtual dialing function, through the same router Internet access to the computer is **** with a broadband account.
Second: wireless switches work in the relay layer, the switch according to the MAC address addressing. Wireless routers work at the network layer and address based on IP addresses. Routers can handle the TCP/IP protocol, while switches cannot.
Three: the switch can make the connection to it more than one computer to form a LAN, if there is a proxy server can also be realized at the same time the Internet function and all computers on the LAN is *** enjoy its bandwidth rate, but the switch does not have a router to automatically identify the packet to send and arrive at the address of the function. The router can automatically identify the address of the packet sent and received, the router is equivalent to the police on the road, responsible for traffic guidance and directions.
Fourth: a few examples, the router is a small post office, an address (IP), responsible for a place to send and receive (personal computer, a server), the switch is a large postal center in the province, is responsible for an address to the various small places in contact. Simply put, the router is in charge of entering the network, the switch is only in charge of distribution, routing route is to find a way to help access the Internet, the switch is only responsible for opening the door, the switch to be no route above is not on the Internet.
Fifth: the router provides firewall services. Routers only forward packets of specific addresses, do not transmit packets that do not support routing protocols to transmit and unknown target network packets to transmit, thus preventing broadcast storms.
What is the difference between a wireless AP and a wireless router?AP is short for Aess Point, generally translated as "wireless access node", it is mainly to provide wireless workstations to the wired LAN and from the wired LAN to the wireless workstations access, access to the access point within the coverage area of the wireless workstations can communicate with each other through it. In a wireless network, the AP is equivalent to the hub of the wired network, which can connect each wireless client, the network card used by the wireless client is a wireless network card, the transmission medium is air.
Wireless Router (Wireless Router) is like a simple wireless AP and broadband router into one extended product, it not only has a simple wireless AP with all the features such as support for DHCP client, support for VPN, firewall, support for WEP encryption, etc., and also includes a network address translation (NAT) function, can support LAN users to enjoy network connectivity ****. It also includes Network Address Translation (NAT) function, which can support the network connection of LAN users***. It can realize the Inter connection in the home wireless network **** enjoy, realize ADSL and cellular broadband wireless **** enjoy access
What is the difference between a wireless router and a wireless AP? What is a wireless AP?Router
When two different types of networks are connected to each other, a router must be used. For example, if LAN2 is Toking Ring and LAN1 is Ether, a router is used to connect these two networks
A switch is similar to a HUB and can connect two LAN segments. It works at the data link layer and filters frames. a SWITCH detects the source and destination addresses of frames. If they are in the same network segment, they are not forwarded. If it is not in the same network segment, it forwards the frame to another network segment.
AP
AP, that is, the meaning of the access point, English for ACCESS POINT, also known as the wireless LAN transceiver, used for wireless networks, wireless HUB, is the core of the wireless network. It is a mobile computer users into the wired Ethernet backbone of the access point.
Wireless gateway, wireless router, wireless bridge actually refers to the same thing, it is the real standard name is "wireless router", or "with routing AP" (note that in the wired network, gateway, router, bridge). (Note that in a wired network, gateways, routers, and bridges are strictly different things, but wireless networking equipment is far from subdivided, so all three terms plus the word "wireless" actually refer to the same kind of wireless equipment used to interconnect different networks).
Those with routing are called wireless routers (i.e., switches with routing), and those without are called wireless hubs.
