Basically, a modem is used for transmitting and receiving data over a communication channel, such as twisted-pair telephone lines, coaxial cables, and optical fibres. Currently the purpose of a modem is to convert a computer's data stream to analog format so that it can be transmitted over the analog telephone line.

There are two different types of modem: Ethernet modems that plug into the network card in the computer, and wireless modems that connect to a computer using a wireless LAN (WLAN). Some modems offer dual Ethernet and USB connection. There are also routers with integrated ADSL modem.
The main benefit of a modem is that it allows you and your devices to access the internet and communicate with the outside world. The downside is that a modem can allow viruses and hackers to enter your network.

Router. A router is hardware device designed to receive, analyze and move incoming packets to another network. It may also be used to convert the packets to another network interface, drop them, and perform other actions relating to a network.
The router sits in between your Internet connection and your local network. But you can't connect directly to the Internet with just a router. Instead, your router must be plugged into a device that can transmit your digital traffic over whatever type of Internet connection you have. And that device is a modem.
The Modem. The modem is an input and an output device. It is used for sending and receiving information and data over telephone lines. Therefore, a translator is needed to put the digital information and data from the computer into analogue form so the data can be sent over the telephone line.
The CPU is the Central Processing Unit and thus is the place where all calculation are completed. In this sense, the CPU is both an input device and output since it is both reading and writing (albeit to memory). In the traditional sense, input devices take external information of some form and deliver it to memory.
The modem provides access to the Internet, and the router broadcasts a WiFi signal, allowing your devices to connect to each other and the Internet. A WiFi-capable device can then use this signal to connect to the Internet. Routers are available from many different manufacturers.
The modem is an input and an output device. It is used for sending and receiving information and data over telephone lines. There are at least two ways that can be used to represent data and information electronically. One way is digital and another way is analogue.

The short answer is yes; companies often upgrade their hardware every few years. As download speeds increase, companies have to provide more sophisticated modems. What you want to know is whether your modem is keeping up with the demands of your service.
Automatic firmware updates ensure that important security updates are automatically delivered to your router to increase the security of your home network. Automatic firmware updates restart your router as part of the update process, which means that you lose Internet access for a few minutes.
There is no way for an end-user to update cable modem firmware manually. To make sure you have the latest firmware update from us: Power off your cable modem for 15 seconds, and then turn it on again. As it reboots, your modem will check if it's running the latest code from your service provider.

Check with your cable company and see if they're made the switch. Then, Google the model number of your current cable modem and see if it's a DOCSIS 3.0 modem. If it is, you're good to go and you don't need to upgrade. If your modem isn't a DOCSIS 3.0 modem, it's time to go shopping.

Click Start, then "Control Panel," then "Phone and Modem." Click the "Modems" tab. Select the modem from the list. If the modem does not appear, it is not installed in Windows or Windows does not detect it.
Short for modulator-demodulator. A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves.
Here's how to find the modem in Windows.
- Choose Control Panel from the Start menu, and then choose Phone and Modem Options. You see one of two dialog boxes.
- Fill in your initial location information.
- Click the Modems tab.
- Select your laptop's modem from the list.
- Click the Properties button.
In short, your router creates a network between the computers in your home, while your modem connects that network—and thus the computers on it—to the internet. When you connect to Wi-Fi, you're really connecting to your router, which forwards traffic between the internet and your computer.
