How does a modum work?
A modem converts the digital signals(used by computer)into analog signals(in telephones) and vice versa.
What is a transcode?
The conversion of analog video to a digital format, or vice-versa.
How does internal modem work?
An internal modem converts digital data from a computer into analog signals that can be transmitted over telephone lines and vice versa. It connects to the computer's motherboard through a PCI or PCIe slot, allowing it to communicate with the operating system and applications. When sending data, the modem modulates the digital signals into analog waves, and when receiving data, it demodulates the analog signals back into digital form for the computer to process. This enables internet connectivity over traditional phone lines, allowing for dial-up internet access.
What does modem stand for anyway (search the webopedia site)?
The term "modem" stands for "modulator-demodulator." It refers to a device that converts digital signals from a computer into analog signals suitable for transmission over telephone lines and vice versa. This process allows for data communication between digital devices and analog communication systems. Modems are essential for internet connectivity, enabling the transfer of information over various types of networks.
What are Modems used for in Internet?
Basically, modem is used to connect the analog world to the digital world. In other words, you can say it is the device that is used to convert the analog signal to digital signal. For eg. the modem connected with a computer is usually converts the analog signal that comes through the wire to the digital bit bcoz computer can only understands the digital signal...
How does a UART convert an analog signal to a digital signal?
A UART does not convert an analog signal into a digital signal. It converts a serial digital signal into a parallel digital signal, and vice versa. The letters UART stand for Universal Asynchronous Receiver Transmitter. It is, fundamentally, a pair of shift registers.
How is a modem facilitats communication different between computer?
a modem is a tool which can change analog sinal to digital signal and vice-versa. when the communication has to take place between the two computers then there is involvement of wires or some wireless technology. if communication exists between then it is through analog signals and computer can accept only digital signal. so,basically modem changes the analog signal to digital when the data is to be received at computer's end and hence it works and facilitates the commmunication between two or more computers.
What is A type of communications device that connects a communications channel to a sending or receiving device is a?
A type of communications device that connects a communications channel to a sending or receiving device is a modem. Modems modulate and demodulate signals for transmission over various types of media, such as telephone lines or cable systems. They enable digital devices to communicate with each other by converting digital data into analog signals and vice versa.
Input and output of a modem?
A modem (modulator-demodulator) converts digital data from a computer into analog signals for transmission over telephone lines or other communication media (modulation) and vice versa (demodulation). The input of a modem is typically digital data from a device like a computer or router, while the output is an analog signal suitable for transmission. Conversely, the input received by the modem is an analog signal from the communication medium, which it converts back into digital data for the receiving device. This process enables internet connectivity and data communication over various types of networks.
How do you know if your TV is digital or analog?
"Standard-definition" (meaning 480i) Cathode-ray tube televisions are analog. CRT TV's are easily identifiable by their immense weight and the fact that their depth nearly matches their width and height. Newer, hi-def (720p, 1080i/p) televisions are almost all either lcd, plasma, or dlp, all of which are digital. for digital TV monitor shouldnot be of CRT.
