Modem is a what not a who. A computer modem is a device that uses an analog carrier signal to encode digital information. The modem is how you connect to dial up Internet.
Modem (from modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. That is the definition of Layer 1.
The definition of a digital device is an electronic device that processes its operations using individual distinct and separate digits and numbers. Digital devices can send, receive, process and store digital information.
An Electronic Device
Yes, it is a method for inputting information; it is a peripheral device
It outputs information from the computer.
A modem is a modulator and demodulator device that modulates the analog carrier signal to encode the digital information and demodulates the signal to decode the transmitted information. The modem usually produces a signal that can be transmitted easily and decoded to reproduce the original data.
The controller processes the input information from sensors.
nops its not a digital device
A byte is neither an input or output device. A byte is a unit of measurement, a unit of digital information.
A digital camera is an input device because it captures information and stores it on the device via the memory card(which is a storage device).
"Digital" is related to the word "digit", in its sense of a number. In a device like a computer, all of the information is translated to binary numbers. Sounds and photographs are reduced to numbers, and are referred to as "digital sounds" or "digital numbers". A digital camera is a camera which records images in this way. In terms of a display, a "digital display" on a clock or speedometer or such similar device displays numbers, digits, to convey the information. An "analog display" on the other hand, displays the information on a dial.
