The modem connects with ISP that offers either cable or DSL Internet service. DSL, however, still allows you to use your landline telephone while connected to the internet.įiber-optic technology doesn’t require a modem for its Internet service. This type of modem delivers high speed internet to your device.ĭSL and dial-up modems use a cable that connects to your phone line. A cable modem uses coaxial cables that connect to the back of the modem and the bolt-like outlet in your wall or on your cable box. There are three types of modems: cable, digital subscriber line (DSL) and dial-up. Modems are not needed for fiber optic connections because the signals are transmitted digitally from beginning to end. NOTE: Since a modem converts analog signals to digital and vice versa, it may be considered an ADC or DAC. Most modern cable modems support DOCSIS (Data Over Cable Service Interface Specification), which provides an efficient way of transmitting TV, cable Internet, and digital phone signals over the same cable line. Cable modems send and receive data over standard cable television lines, which are typically coaxial cables. This allows for higher data transfer rates than dial-up modems and enables them to not interfere with phone calls. DSL modems operate over standard telephone lines, but use a wider frequency range. Modern modems are typically DSL or cable modems, which are considered "broadband" devices.

Dial-up modems also required full use of the local telephone line, meaning voice calls would interrupt the Internet connection. These modems operated over standard analog phone lines and used the same frequencies as telephone calls, which limited their maximum data transfer rate to 56 Kbps. The first modems were "dial-up," meaning they had to dial a phone number to connect to an ISP. Similarly, it converts digital data from a computer or other device into an analog signal that can be sent over standard telephone lines. It converts or "modulates" an analog signal from a telephone or cable wire to digital data (1s and 0s) that a computer can recognize.
Modem is short for "Modulator-Demodulator." It is a hardware component that allows a computer or another device, such as a router or switch, to connect to the Internet. In wireless networks, by configuring VPN in routers, it can be used in the client-server model, which allows sharing the internet, video, data, voice, and hardware resources.

Then the router provides the executive the method to share his software tools and other applications with the manager with the help of routers by connecting their PCs to the router using WAN architecture. For example, the software manager of an organization is located in Agra, and its executive is located at a different place like Pune or Bangalore. Routers are also used by software testers for WAN communications. It can be configured in a way that allows for few users to access the overall data and allows others to access the few data only, which is defined for them. Furthermore, it can send data all over the world with the help of an IP address of the destination. Internet service providers widely use routers to send the data from source to destination in the form of e-mail, a web page, image, voice, or a video file. It provides support for a fast rate of data transmission because it uses high STM links for connectivity that's why it is used in both wired or wireless communication. Routers are used to connect hardware equipment with remote location networks like BSC, MGW, IN, SGSN, and other servers. There are various areas where a router is used: The static routing tables are configured manually, and the dynamic routing tables are updated automatically by dynamic routers based on network activity. There are two types of tables in the router that are static and dynamic. For example, the office router along a single default path instructs all networks to its internet services provider. So, it may fail to find the best way to forward the data for a given packet. It uses the routing tables to determine where to send data and from where the traffic is coming.Ī routing table mainly defines the default path used by the router. Most of the routers have several ports to connect different devices to the internet at the same time. Routers use a modem such as a cable, fiber, or DSL modem to allow communication between other devices and the internet.
