Paragraph 1: Cats
Why is it called a Moden, a Moden, a Moden, a Moden, a Moden, a Moden, a Moden, a Moden, a Moden, a Moden.
Your computer ability undertakes dial-up to get online, some small area or a few areas have omitted to use cat this step, give you a network cable directly, insert a computer to be able to dial directly.
I used an5006-01 A (optical cat), which converts the optical fiber into A network cable that can be plugged directly into the computer
Generally, there are three cases of surfing the Internet
Segment 2: Router
As we all know, the router can share the network with multiple computers by inserting the network cable and setting up the dialing. Generally, the router consists of two parts, WAN and LAN. WAN is used for dialing.
A LAN is used to exchange data within a local area network (LAN). Just like a switch, our computers plug into a LAN port to access the Internet.
For example, when a computer plugged into a router needs to access the Internet, the WAN port connects to the Internet and sends data to the LAN port, which then sends data to the computer. How does a wireless router work? The wireless part of a wireless router usually belongs to a LAN.
So generally called WLAN, so he is with the function of the LAN port is the same, can be connected to the wireless router device to access the Internet, if the wireless part of the WAN, then the wireless can only be used when dialing, such as connecting to the CMCC, with the router to rub the neighbor’s WIFI.
Why do you plug in the route to access the Internet? Because the DHCP server built into the route can automatically assign IP addresses to computers using the route, so they can plug in and access the Internet.
Why does someone use a router slow down, because the route can not take up so many computers, an ordinary household route with 20 computers, your 1000M network line is still out of line, slow download, the exchange performance of the route is too low.
A router is like a small computer, consisting of CPU and memory. If the CPU is low, the switching performance is low, the data exchange is slow, and the network speed is slow. There may be problems with the router firmware, so it is recommended to carefully choose a router when buying it.
My Mercury wired router has no wireless capability
My Huawei HG255d modified version of wireless router, OPENWRT firmware, can be one line multiple dial, free to improve the network speed
Segment 3: Routing cat
A router cat is a combination of a router and a cat. It functions as both a cat and a router
My ZTE H618B, this is the wireless routing cat, and ordinary router no different, but in the need of the cat environment, can be a person when two roles
Segment 4: Switch
Finally arrived the switch, the switch simply said, namely cannot dial the router, so understood, he has LAN only, do not have WAN, the switch is how to get online?
Plug the network cable into any port on the switch, plug the computer into any port on the switch, and plug computer 2 into any port on the switch, so that both computers need to dial up to access the Internet.
Is broadband connection, the switch and did not use the router dial method is the same, so the switch is used for data exchange, not to say more, I will draw it out.
