The modem connects the telephone line to the computer system or router. Join DataFlair on Telegram!! How does a Modem work? Stay updated with latest technology trends It accelerates data transfer by combining data and sending it all at once. It also does data compression, error correction, and information flow control. We usually get the modem from the ISP only when we sign up for a new internet package. It converts incoming analog signals from the internet to digital signals and sends them to the computer, and vice versa. As a result, we require a device capable of converting an analog signal to a digital signal and vice versa. That is, the internet delivers an analog signal, but the computer system can only read digital signals. The rationale for using a modem to connect to the internet is that the internet and the computer utilize two distinct signals. It serves as a link between the internet/phone line and the computer. It keeps a dedicated connection with the ISP in order to obtain an internet connection for home or business. What is a Modem?Ī modem is a device that either modulates or demodulates a signal. However, in order to connect to the internet for our home/office network, we need both a modem and a router, either integrated or separate. Both devices are now integrated and are normally delivered by the ISP (Internet Service Provider) when we sign up for a new internet plan. The router is also a box-type device that allows many computer systems (wired or wireless) to access the internet at the same time.

In comparison, Routers come with 2, 4 or 8 ports for enabling wired connection to multiple devices in addition to providing wireless connection via WiFi Network. While the Router in most cases is equipped with firewalls to screen the data, before transmitting it to other devices.Ī Modem has 2 ports, one port connects to the Internet Service Provider and the other one can be connected to Router or computer. While the Router can be connected to multiple devices using wired connection (using Ethernet cables) and wireless connection (WiFi network).Ī modem receives data from Internet Service Provides and transmitts that data without screening it. Modem vs router define Pc#Difference Between Modem and RouterĪ Modem can only connect to one device, it can either be connected to PC or the Router. This offers you with more control (parental Control Settings) and better performance, especially if your own Router is more advanced compared to the ISP provided Modem/Router combo. However, you can still use your own Router by plugging your own Router to one of the Ethernet ports of the combo device. While Routers and Modem serve different functions, most Internet Service Providers offer combo devices that function both as Modem and Router. Desktop, Laptops, Tablets, Printers, Phones and other devices connect to Router for Internet Combined Routers and Modems Router gets internet connection from the Modem and creates a Home or Local Wi-Fi NetworkĤ. Modem gets internet connection from the wall mounted Cable Port/Socketģ. Internet Service Provider (ISP) brings connection to the wall mounted Cable port/SocketĢ. Here is what a typical home network looks likeġ. Hence, Router needs to be connected to Modem, in order to create a WiFi Network that multiple devices in your home or Office can connect to. While a Modem can provide wired connection to a single device, it cannot provide wired and wireless connectivity to multiple devices. In comparison, Modern Routers can provide both wired and wireless Internet connectivity to multiple devices like laptops, tablets, printers, phones and other smart devices. Initial routers only had multiple Ethernet ports that allowed devices to connect to a Local Area Network (LAN). What is Router?Ī Router can be defined as a networking device that allows various devices to share a network connection. The Wall Socket is connected to the telephone network of your service provider. Going by the nature of connection, Modems can be classified as Cable Modems and DSL Modems.Ĭable Modems make use of a Coaxial Cable Connection (similar to Cable TV) to connect to the Cable Port on the Wall of your home, which in-turn is connected to the cable network of your Internet Service Provider.Ī typical DSL Modems is connected to the telephone socket on the Wall of your home or office using a telephone cable and a connector known as RJ-11 jack.
