Exempel på hur man kan använda MODEM i en mening

• Ambient Technologies, semiconductor company specialising in modem ICs, spun off from Cirrus Logic in 1999 and purchased by Intel in 2000.
• In modern usage, the key has no well-defined purpose, but while this is the case, it can be used by software for miscellaneous tasks, such as to switch between multiple login sessions, to terminate a program, or to interrupt a modem connection.
• It formally defines signals connecting between a DTE (data terminal equipment) such as a computer terminal or PC, and a DCE (data circuit-terminating equipment or data communication equipment), such as a modem.
• In the computer hacking scene of the 1980s, demon dialing was a technique by which a computer was used to repeatedly dial a number (usually to a crowded modem pool) in an attempt to gain access immediately after another user had hung up.
• 4 kbit/s, introduced at a price of $129 (this modem is also compatible with the Palm III and Palm IIIx devices).
• Fall back is a feature of a modem protocol in data communication whereby two communicating modems which experience data corruption (due to line noise, for example) can renegotiate with each other to use a lower-speed connection.
• Channel bonding (or modem bonding), an arrangement in which two or more network interfaces on a host computer are combined.
• For example, when a computer communicates with another device such as a modem, the two devices will signal each other that they are switched on and ready to work, as well as to agree to which protocols are being used.
• In telecommunications, a narrowband modem is a modem whose modulated output signal has an essential frequency spectrum that is limited to that which can be wholly contained within, and faithfully transmitted through, a voice channel with a nominal 4 kHz bandwidth.
• The TA therefore fulfills a similar function to the ones a modem has on the POTS network, and is therefore sometimes called an ISDN modem.
• A modem whose modulated output signal can have an essential frequency spectrum that is broader than that which can be wholly contained within, and faithfully transmitted through, a voice channel with a nominal 4 kHz bandwidth.
• A cable modem is a type of network bridge that provides bi-directional data communication via radio frequency channels on a hybrid fibre-coaxial (HFC), radio frequency over glass (RFoG) and coaxial cable infrastructure.
• The console supports limited online gaming for a few games via a GameCube broadband or modem adapter and can connect to a Game Boy Advance with a link cable for exclusive in-game features using the handheld as a second screen and controller.
• Dial-up connections use modems to decode audio signals into data to send to a router or computer, and to encode signals from the latter two devices to send to another modem at the ISP.
• Automatic baud rate detection (ABR, autobaud) refers to the process by which a receiving device (such as a modem) determines the speed, code level, start bit, and stop bits of incoming data by examining the first character, usually a preselected sign-on character (syncword) on a UART connection.
• The computer sends and receives data via an input/output device; examples: storage device (such as disk drive, solid-state drive, USB flash drive, memory card and tape drive), modem, router, gateway and network adapter.
• For example, in a modem, which is a contraction of the terms modulator/demodulator, a demodulator is used to extract a serial digital data stream from a carrier signal which is used to carry it through a telephone line, coaxial cable, or optical fiber.
• Usually, the DTE device is the terminal (or a computer emulating a terminal), and the DCE is a modem or another carrier-owned device.
• Where a system (such as a modem) involves round-trip analog-to-digital processing, a distinction is made between analog loopback, where the analog signal is looped back directly, and digital loopback, where the signal is processed in the digital domain before being re-converted to an analog signal and returned to the source.
• Initially only offering dial-in services via modem and ISDN, it later expanded to offer dial-up access as well as ADSL, VDSL, and fiber-optic (FTTH) services as well as mobile internet (but no calling or texting).
