The cable modem is known as the broadband device as it allows the computer to communicate with ISP over a landline connection.It uses a PSTN facility (Public Switched telephone network) and provides a transmission speed of 56kb/sec.Dial-up modem establishes the internet connection by connecting the ISP to the computer using the conventional telephone line.These modems use radio frequencies to transmit the data through the air and also provides good transmission speed.Wireless modems are connected to the computer systems without any cable, and most people use these modems for their personal use.The installation is complex, and its data transmission speed is also slow hence it is used for the dedicated computer in homes/ or small spaces.It looks similar to an electronic circuit and mounted into an expansion slot of the motherboard.As its name suggests, the internal modem is installed over a PC's motherboard, termed as the internal modem.It is expensive but still used due to its high-speed data transmission in offices, mostly to avoid interruption in network connectivity.The installation is very easy, and it also provides a high data transmission rate.
#Router vs modem serial#
The external modem is connected outside the computer system using a serial cable.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.
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.
