Moreover, many routers also contain built-in switches that allow you to connect multiple wired devices. It has one connection to the internet and one connection to your private local network. How Router Works?Ī router connects multiple networks and tracks network traffic between them. The device sends and receives an electrical signal with the help of wires, using a few MHz. These copper wires travel from your property to a neighborhood node, and to your service provider, which may be several miles away. The modem connects with ISP that offers either cable or DSL Internet service.
It allows you to split your internet connection to all of your devices.Have protection against the overload problem.Put the demodulate into RS-232 format connect to RS-232 interface.
Receiving the analog signal and demodulate them.Offer protection against line overload and other problems.įunction to be performed at the receiving end:.Send the dialing signal if the modem is designed to dial without the presence of a user.Perform the line control and signaling to other ends of a phone line.Convert the data (0s and 1 s) into an appropriate analog signal.Functions of Modemįunction to be performed at the transmitting end: This router allows interfaces with an ATM (Asynchronous Transfer Mode) network.ĭistribution routers aggregate traffic from multiple access routers, which is used for enforcing the quality of service across a WAN.Ī core router is a router designed to operate in the Internet backbone, or core. This type of router provides the Network Address Translation (NAT), which is required to support several computers.īrouter is a network device that works as a bridge and as a router. However, if we are using the half-duplex mode, then the same frequency can be used for transmission as data flows in the same direction only at a time.Ī wireless router combines multiple base stations (wireless access points) as well as a number of wired LAN switches.Ī modem router helps to connect more than one computer to a single DSL line for Internet access. Two-Wire Modem: This type of modem uses a pair of wires for both incoming and outgoing carriers. Therefore, the same frequency can be used for transmission at both ends. These types of modems have two carriers on the line.įour Wire Modem: It is a separate pair of wires that is used for the incoming and outgoing carrier. So, if the modem is receiving the incoming signal, then it displays indication light to the sending point to stop transmitting data till the time it completes the process of receiving signals.įull Duplex Modem: This type of modem permits transmission in both directions at the same interval of time. Half Duplex Modem: This type of modem allows you to transmit a signal in one direction at one time. They can also be inserted inside the USB port for internet access.

They come built-in with a PC or a laptop. Mobile Broadband Modems: This type of modem makes use of mobile telephone lines such as GRPS, Wi-Max, UMTS, etc. It can be configured internally/ externally with the television line to convert the signals into the compatible mode.
It offers to speed up to 2 Mbps and even more, which depends upon the type and configuration.Ĭable Modem: This type of modem is designed in a way to carry radio and television signals. It will radiate at higher frequencies and cover more distance than the dial-up modems. It modulates the binary data into the carrier signal on the telephone line.ĭSL Modem: DSL model uses twisted pair cable for transmission of signals. It offers an interface between the digital system and an analog system. Dial-up Modem: This type of modem are using the analog telephone line to connect two end devices like two personal computers.
