The router What is it? Is it different from a modem?
Routers also known as routers or routers are devices that make an interconnection between computers working in the field of a network. Its main function is that to take care of the construction of a route which it will reserve for each network packet within a set of computers. These devices are often used in homes to access broadband services.
They also provide connectivity within small offices and large enterprises where you can even find routers of all sizes. The routers currently on the market are not only routers, but are also equipped with the so-called Local Customer Equipment (CPE). Inside this equipment is the modem. Next we will see the functionality of this device.
Does the modem perform the same function as the router?
This device is responsible for transforming digital broadcasts into analog, a process known as 'modulation'. It also does the process in reverse, ie it converts analog signals into digital signals, which is called "demodulation". This is intended to allow communication between computers via a telephone line or cable modem and thus have access to the Internet.
In light of the above, we can identify two types of modems: analog and digital. In turn, the analog can be external (located near the computer) or internal (in forms of cards located in the expansion slots). In comparison, the digital type has a higher connection quality and takes much less time to install.
The WiFi access points, similar to a router or a modem?
A Wi-Fi access point is one that allows a connection between devices and an Internet network. They have radio transmitters and antenna and are mainly used in corporate environments allowing workers to connect from anywhere in the company. They are also able to provide wireless Internet access in places where there are several public places or commercial companies: bars, shops, etc.
The WiFi access point was like an extension of the router. Use an Ethernet cable to connect to it which allows a connection of higher quality and speed. So it is able to distribute the signal via WiFi to related devices and thus get a larger diameter of the signal.
When talking about the differences between these three devices, we can see that each performs specific functions. It is true that they are able to provide us with an Internet connection, however it is interesting to note that a WiFi access point depends on a reuter and in turn the reuter needs a modem.
The router, modem and WiFi access point working together are capable of connect a large number of users and offer them a good browsing experience. We hope that by explaining what they are and what their functions are, you have been able to clarify your doubts. Therefore, we would like to know your opinion on how this post has helped you.
