Router has a WAN input jack (connector) to connect the cable from the Internet provider and several LAN connectors, with which to dock the cables of fixed network devices (computers). The desired number of outputs is used. This part of the device can be thought of as a router without wi-fi.
Wireless router: how it works without a phone
The Internet is gradually gaining a leading position in the field of receiving information. More and more means of its delivery are becoming available. Users of the World Wide Web have a variety of modern devices at their disposal. To use them together without interfering with each other helps to organize a wireless router.
It is important to note that router and router are physically the same device.
Router is an English word. Router is the Russian translation of it.
The router's operating principle is to distribute information flows – incoming and outgoing – according to a route map stored in its memory under the control of its own processor. This map (routing table) is a database with a set of rules that determine the best way to transmit packets of information and is stored in the memory of the device.
The number of routes is determined by the number of devices operating in the network created by the router at a given time. The router has its own IP address on the Internet. It itself, in turn, is constantly addressing elements of the local network, using the IP addresses it has created for them. In this way several devices simultaneously gain access to the global network using Wi-Fi technology.
Types of Wi-Fi routers
Wi-Fi technology allows you to transmit messages using radio waves.
Wireless quality or wireless fidelity is a literal Russian translation of the English acronym.
Equipment using this technology is used to organize local wireless networks. These networks are deployed in places where the use of cable lines requires high costs.
Router in wireless networks acts as a dispatcher and works both as a transmitter and receiver of radio signals. What kind of routers are there? According to the technology of data transmission to the router from the Internet provider there are three groups:
Devices in the first group receive information over telephone two-wire communication lines. The speed of data transfer at the present stage of development can not meet the requirements of most consumers.
For routers of the second group, you need a special cable to exchange information. It consists of two twisted pairs, one of which is used to receive and the other to transmit output information. The speed at which such routers work satisfies most consumers (up to 100 Mbps). This method is currently the most efficient and reliable.
Using twisted pair allows you to answer the question how to get internet in the apartment without a phone.
For LTE routers to work there is no need to lay cables. The exchange between the Internet service provider and the access point, which is a Wi-Fi router, is carried out over the air via radio waves.
They work with 3G and 4G mobile networks. The transmit-receive speed is not yet high. The need to use such routers occurs where there is no access to communication using cable.
Modern routers are the centers of corporate and home networks. They organize the exchange between its individual elements (participants) both by means of cable lines and by means of a radio signal. They are combined devices, taking advantage of different types of consumer connections depending on the tasks assigned to each of them.
What is the difference between a router and a router
When first encountering terms like router and router, some people assume that we are talking about two different devices related to wireless access. However, we are actually talking about the same equipment, with the Russian and English versions of the name.
What is a router? The name itself comes from the concept of "route", that is, the device paves the way from the signal source to the connected gadgets and back. What is a router? It's essentially the same thing. Route in English means a path, a road, a route, a router indicates a route.
The name router is most commonly used in technical literature and as the official name of manufacturers. The word can often be found on the price tags in hardware stores. However, retailers themselves call the small box with antennas a router, as do Internet service providers. Therefore the answer to the question, what is the difference between the router and the router, is obvious – nothing.
What is the difference from the modem
Often people, far from computer terminology, confuse a modem with a router, thinking that they are the same thing. However, they are two completely different types of equipment aimed at performing different tasks. A modem is a transmitter that connects one device, such as a computer, to the World Wide Web. Modems can be of the built-in type as well as of the external connection, connected to the device via a USB connector or a telephone cable. The latter are rarely used today, as they have low signal rates. Cellular operators offer subscribers 3G and 4G models of modems, which are indispensable where there is no possibility of laying cable.
A modem and a router can't replace each other, but they almost always work in tandem – the first one picks up the signal and transmits it to the main device, while the second one distributes the network from the hub to the users.
