The modem can be of various types based on data transmission and how it is installed. Without a modem, we cannot connect to the internet. The below diagram is converting the incoming analog signal coming from telephone-lines/optical fiber to a digital signal and sending it to the PC. Or it is connected with the router to connect with multiple devices. It connects the ISP(internet service provider) to the home network directly for the single PC. It connects the devices with the ethernet port given in it. The modem is placed between the telephone line and the computer system or router. The working principle of the modem is based on the same process.
It speed-up the process of transmission of data by grouping the data and send it in one go.Īs you must have understood till now that modem is responsible for modulating and demodulating the signal. It also performs data compression, error correction and controls the flow of information.Usually, we get the modem from the ISP only when we take a new internet plan.It modulates the incoming analog signal from the internet to digital signal and directs it to the computer, and vice versa.So, we need a device that can convert an analog signal to a digital signal and vice versa. It means that the internet sends the analog signal, but the computer system can only understand the digital signal. The reason to use the modem for an internet connection is that both the internet and the computer take two different signals.It acts as a bridge between the internet/telephone line and the computer.It maintains a dedicated connection with the ISP to get the internet connection for home or business. A modem is a device that modulates or demodulates the signal.In this topic, we will understand the difference between the modem and router, but before understanding the main differences, we will first understand what Modem and Router are, their features, how they work, and what feature makes them different. Although most of the time people get confused to identify both the devices, both devices have two different roles on a network that we will know on this topic. But to get the internet connection for our home/office network, we need both modem and router either integrated or individual. Nowadays, both the devices are integrated and usually provided by the ISP(Internet Service Provider) when we take the new internet plan. The router is also a box-type device that enables multiple computer systems (either wired or wireless) to simultaneously use the internet. Router | Difference between Modem and RouterĪ modem is a box-type device that connects your home/office network directly to the internet.
