He router and the modem they are devices in charge of the internet connection for a business or home, but they have several differences that we detail below.
Differences between Router and Modem
To talk about the difference between modem and router Remember that both are responsible for the internet connection, but then their differences are highlighted:
- level In a modem The level of the data link is Second layerwhile on a router it is from third layer.
- Function He modem It makes the internet connection easier thanks to the transmission and reception of data, highlighting that the transmission is executed through telephone lines. A ruoter directs the data inside a network, so the data moves between interconnected devices and the modem.
- Ports In a modem The usual thing is that there are two, one to connect to the server (ISP) and the second to connect to the router if the network is large. A router It has 2, 4 and sometimes 8.

- Type of device He modem is an interconnection team and the router It is a connection device.
- Connections A moden It can be connected to a computer through the Ethernet port and also emits signals via WiFi. He router It can be connected with multiple gadgets such as cell phones or tablets, both via Ethernet or WiFi.
- Need for an internet connection A modem necessary, Meanwhile he router It is not necessarily because your work is more related to providing extra security and enabling multiple connections simultaneously.
- Independence He modem It is independent and does not require the router, since its job is to deliver information to a device. On the other hand the router You will share information between devices, but not be useful without a modem that allows internet connection.
- Security He modem Complies with the basic safety standards. A router provides security conditions and measures on a larger scale so that the network is protected.

What is a router?
A router, router or rter, is a device that provides connectivity conditions at the network level or at level three according to the OSI model. In that order of ideas it is a device that allows different networks or computers to connect to each other, as is the case of sharing the same internet connection.
To function, the router It uses a protocol for routing, thus enabling it to communicate with other routers and therefore share information with each other, to identify the route that is most appropriate and fast when sending data.
What is a Router for?
He router serves in its most common use so that an office, house or small business can easily access the same internet connection. Therefore, it is a device that acts as a receiver of the network connection to distribute it among the other computers that are connected. Therefore, it connects to an Internet network or if you want to a local area.
In the last time they have developed wireless routers, which functions with mobile and fixed networks, which is why they are going to provide Wi-Fi connections to the other devices in an office, housing or larger spaces.

Routers provide connectivity and accordingly can be classified into types:
- Connectivity Small fice, Home Office (SOHO) They are used with frequencies in homes to connect to a broadband service such as IP over cable or ADSL.
- Company router In companies, routers are of all sizes, so depending on the needs of the team.
- Access They include SOHO and are on customer sites such as a branch.
- Distribution Add traffic to multiple access routers, both for the same site or when obtaining data flows that come from multiple sites
- Core In certain cases the router can be a backbone to interconnect and thus distribute connectivity on several levels.
- Edge They are responsible for linking autonomous systems with a backbone internet network or other kind of autonomous systems.
- Wireless routers Traditionally they are linked to fixed networks, but nowadays wireless routers are a reality for fixed and mobile networks (WiFi, Edge, GPRS, UMTS, Fritz! Box, WiMax, among others). The principle is the same, but in this case the connection is wireless with the devices.
- Domestic routers They are the ones that sell in a typical way for homes and in reality they are nothing more routers, but customer local teams They have modem, router, switch and sometimes WiFi access points.
What is a Modem
A modem It is a computer device that converts a digital signal into analog and vice versa, which is why they will be able to transmit in an understandable way. It is also a peripheral input Y peripheral output which can be internal or external. It also allows you to establish a connection to a telephone network and access other networks such as the Internet.
What is a Modem for
He modem it serves in essence so that the signals that are transmitted are understandable, one of the main problems that occurred during the development of the telecommunications, where these types of stable connections over long distances were not as common as they are today.
In this way, the modem serves to communicate two computers with each other, which is why it fulfills the task of exchanging digital data. It is recalled that a conventional telephone line transmits waves and not impulses of information or information technology and in this case the modem assumes the task of converting that data into digital information.
Analog modem It is a modem that converts the digital signals of a computer to analogue telephone signals or vice versa. Thus the transmission and reception of the data is given thanks to a standard telephone line. They are divided into:
- External modem They are located near the computer and connect to the side, while the other is connected to the telephone line.
- Internal modem Its shape is that of a card and they are located in an expansion slot. They only have an external output for the telephone line.
Digital modem They require a digital telephone line called ISDN or Integrated Services Digital Network for proper operation. It is possible to use copper wires for an analog line connection so it is a simple change to a digital line.
Cable modem It is a device that allows access to the internet at a high speed thanks to the cable TV. They are external boxes that connect to the computer. They have two connections, one for the wall connection cable and the other for the computer on an Ethernet interface. They are classified in:
- Coaxial fiber optic modem It is a bidirectional device with a upload speed between 3 to 30 Mb and download between 128 kb and 30 Mb.
- Unidirectional Modem It is a line preceding the coaxial fiber optic and requires a conventional modem for functional. The upload speed is approximately 2 Mb.
