What is a Modem?
The modem is a device – of box shape – that ensures connectivity between your home and your internet service provider. The primary function of a modem is to receive and translate the signals coming from your ISP for the devices in your home or office. A unique IP address is ascribed to every modem that is used to identify it on the internet.
Typically, modems are provided by internet service providers. In case of any dysfunctionality, they charge a fixed cost to either repair or replace it. In receiving and transmitting signals, a modem works independently. Modems can be divided into four basic types: DSL modems, cable modems, dialup modems, and broadband modems.
A modem builds connectivity by translating signals coming from lines; therefore, it offers a speedier internet. Modems come in a variety, depending on their price and usage scope. Since modem also regulates the security of a network, expensive and latest modems are designed the way to provide an unbreachable security layer to the connected devices.
What is a Router?
A router is a vital component of every network – be it small or large. It is a device that connects multiple users on the internet and regulates their connection by ensuring safer and faster communication. When a modem is connected to the ISP, it is followed by a router to form a network. The router takes the translated signals from the modem and uses them to distribute to the connected devices on the web.
Mainly there are two types of routers: wired and wireless. The wired router is connected to the modem through a cable and uses multiple wires to transmit data packets to other connected devices. The wireless router also uses a wire to connect to the modem; however, it sends the signals to other devices wirelessly. Just as where there is the internet, there are security concerns – a router is at times vulnerable to cyber attacks.
Routers with high-level security are relatively expensive because their manufacturers roll out frequent updates to strengthen the safety of their routers. By default, a router’s administrative controls are not protected by a security wall of a personalized username and password. In order to make it secure, these credentials are set by the user.
Difference Between Modem and Router
- The modem connects a place to ISP, whereas the router distributes signals to the devices.
- The modem translates the signals coming, whereas the router delivers them to users.
- The modem is independent in functionality, whereas the router requires the modem to work.
- The modem is a wired device, whereas a router can be wired and wireless.
- The modem plays less role in the regulation of a network, whereas the router is the sole regulatory component.
Comparison Table Between Modem and Router
| Parameters of Comparison | Modem | Router |
| Function | To connect your place to ISP and translate signals | To distribute signals on a network |
| Wired/Wireless | Modems are wired in their connection to ISP | A router can be wired or wireless as per choice |
| Working Requirement | Works independently in receiving signals | Needs a modem to get internet connectivity |
| Network Security | The modem has more role in network security | Routers do play a role in security but less than a modem |
| Network Regulation | A modem does not regulate the network | Routers are responsible for handling a network |
