Modems used to exploit Internet services of ISPs must be correct ( DSL, copper or optical ) to be able to run with the ISP provided. Modems mainly used are coaxial cable modems, ADSL and fiber optic cables. Meanwhile, the DSL modem ( dial-up form ) connects directly to the phone line.Īccording to Wikipedia, the modem ( modulator and demodulator ) is a device that converts analog (analog) signals into digital (digital) signals and vice versa. Through a coaxial cable or fiber optic cable from Internet-provided stations connected to your home, the modem will act as a transfer for data packets provided by the ISP to an Internet connection for the router or linked devices. Modem is a device that communicates with the network of Internet service providers (ISPs). Without a modem, the router only performs the function of setting up the internal network, not the international Internet connection. If the router is a child, the modem is the mother. The router will only be able to connect to the Internet by connecting a dedicated Ethernet cable to a modem. However, only for a router ( not 2-in-1 ), you can hardly connect to the Internet. Servers on the Internet will connect to the router via modem and this device is responsible for routing traffic to other devices on the network. The router receives Internet data from a modem and each router has a unique public IP address on the Internet. In addition, the router usually has quite a lot of Ethernet ports ( also called LAN ports ) that allows users to be able to connect with many other devices via cable connection ( wired or wired network ). This device allows creating a Wi-Fi network for use with many other devices. Currently, wireless routers are often equipped with one or more antennas known to users as "antennae" that allow them to adjust to improve the direction of the wave. A typical router today is a wireless router that broadcasts Wi-Fi ( some places are called access points or APs ). Routing occurs on the 3rd floor in the 7-tier OSI model.īut to understand, the router is a device for sharing the Internet to many other devices in the same network layer. Understandably, routers are routers or routers used to transfer data packets over a network to the terminals, through a process called routing. But there will probably be many people who cannot distinguish the differences between them. ![]() It exists anywhere with an Internet connection from family to office. ![]() Today, the concept of Modem and Router is no stranger to each of us. ![]()
