modem
B1Neutral to technical
Definition
Meaning
A hardware device that converts digital data from a computer into a signal suitable for transmission over a telephone line or cable, and vice versa.
Any device that provides connectivity between a local network and a wider network (e.g., the internet), often combining modem, router, and Wi-Fi functions in a single unit (commonly called a 'router' in everyday language).
Linguistics
Semantic Notes
The term is a portmanteau of 'modulator' and 'demodulator'. While the core function remains, the physical form has evolved from dial-up devices to broadband (DSL, cable) units, and the term is now often used interchangeably with 'router' by non-technical users.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'модем' (direct cognate, same meaning).
- Do not translate as 'маршрутизатор' (router) – though devices are often combined, they are distinct functions.
Common Mistakes
- Using 'modem' to refer only to the Wi-Fi broadcasting function (which is the router's job).
- Pronunciation: Incorrect stress (e.g., mo-DEM) is common among learners.

FAQ
Frequently Asked Questions
No, they are different. A modem connects your home to your Internet Service Provider. A router creates a local network and distributes the internet connection to your devices, often wirelessly. Many devices now combine both functions.
The noise was the 'handshake' – the process where two modems established a connection by agreeing on communication protocols. It was the sound of the analogue signals being sent over the phone line.
Yes, but it's often a different type called an optical network terminal (ONT) or a fibre modem. It performs a similar gateway function but for fibre signals instead of telephone/cable signals.
Yes, a single computer can be connected directly to a modem via an Ethernet cable for internet access. However, to connect multiple devices or use Wi-Fi, you need a router as well.
