What is a cable modem?

NETGEAR Cable Modem CM600


High-speed cable modems are basically hardware that connects computers and other digital devices to an internet service provider or ISP. It is called a cable modem because it uses a coax cable instead of a DSL line or a telephone line. This coax cable uses a similar infrastructure that carries television to homes or businesses. In essence, cable modems are like digital translators which receive data through signals from the ISP network and then translate the data into a language which routers can then transmit across a network through Wifi Connection.

Design and Components

In terms of physical design, the CM600 has a beveled body with triangular cutouts for ventilation. Its LED panel displays five icons that light up and is held at the left of the bevel. The position of the LED panel makes it inconvenient to monitor the network status. It would be better if there was a direct view of the illuminated icons.

Since the modem is standing diagonally, the panel is facing the left instead of the front and this is something that needs consideration on when the device is being placed. The reset button, Gigabit Ethernet port, power input, coaxial connection, and the power button are all found in the back panel – a convenient feature that is often overlooked by many manufacturers.
