Merdeka.com – We’ve often heard the word router. We know that this router is the tool behind the internet network that we often feel every day. But what exactly is this tool?
Routers are hardware used to connect multiple networks, be they the same network or misaligned networks. Routing is the process of sending data packets over a network based on one device to another.
Each router has several facilities, namely DHCP (Dynamic Host Configuration Procotol) & NAT (Network Address Translator) facilities. A DHCP facility is a service that can distribute other IP addresses on a computer device.
While NAT is a facility that allows an IP address or internet connection can be shared with other IP addresses. By getting this other IP address, a device can connect to another device.
For more details, here we summarize from various sources, some things about the function of the router, the type of router, the difference in using a modem, and how the router works.
Besides being able to connect 2 or more networks, the router function is also useful as follows:
The first function of the router is as a network link. As already explained, the router has a function to connect several networks so that the user can send data packets based on one network to another network.
The connection process works using a way of distributing ip addresses to every computer in the network, either inactively or using DHCP (Dynamic Host Configuration Procotol).
The second function of the router is to transmit news. Another function of the router is to transmit information or data based on a network to another network where the system works such as a network bridge or bridge.
Connecting Network to DSL
The third function of the router is to connect a local network using a DSL (Digital subscriber line) connection or better known as using a DSL router. Today’s router technology is more sophisticated, where its use not only uses LAN cable connections, but also by using wireless technology.
Wired routers are generally connected directly to a modem or Wide Area Network (WAN) over a network cable. These routers are generally installed using a port connected to the modem to connect using the internet.
Routers can also connect wirelessly to devices that support the same wireless defaults. Wireless routers can receive facts & send information to the internet.
4 by five pages Different Routers using Modem
Because modern modems are often equipped using built-in routers, the difference between modems and routers is sometimes unclear. But those who remember the beginning of the advent of the internet will know that the two have different functions.
You need a modem to connect to the internet through your ISP. While you need a router to connect poly devices in a network, including your modem.
Therefore, routers allow your modem and other devices to transfer data by one location to another. A modem is a channel that sends data to the internet and receives data according to the internet.
You need a modem because the type of signal used by personal computers with those used by the internet is generally not the same. Computers and mobile devices use digital signals, ad interim internet works on analog signals.
The modem switches these frequencies to a valid format. So, this signal conversion is a special function based on the modem. While the router function works to coordinate the frequencies.
five out of five pagesHow the router works
Simply put, the way a router works is to connect devices that are on the network by forwarding data packets between them. This data can be sent from one device to another, or based on the device to the internet.
Routers can do this by assigning local IP addresses to each device on the network. This serves to ensure that the data packet ends up in the right place, and does not get lost on the network.
You can imagine this data to be the courier delivering the package. Couriers need the perfect delivery address so that the package can get to the perfect recipient.
Your local computer network is like a suburban street. It needs a clear and precise location in the vast area where we live.
If the location address is not clear, then the package can easily end up in the wrong house due to limited news. With this image, it provides an explanation that the router is useful to ensure that each location (device) has a unique number so that the packet goes to the correct address.
If you need to return data to the sender, or send your own packet, the router can also be used to do this job as well. Although on handling each packet separately, routers do this job using very quickly as a result of which it feels instant, even when there are multiple devices sending data simultaneously. [ank]
