What is an ADSL modem?
Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data communications technology that enables faster data transmission than a conventional modem can provide. A modem which can do such a job is called an ADSL modem.
What is A technology that uses cable TV lines for data transmission?
cable modem - A technologythat uses cable TV lines for data transmission
What are the characteristics of cable modem transmission systems?
Television channels are used as data upload and download channels. Bandwidth is shared between subscribers in one area.
What is the first commercial modem that was manufactured by AT and T in 1926?
The first commercial modem manufactured by AT&T in 1926 was the Bell 103 modem. It was designed for data transmission over telephone lines and could transmit data at speeds up to 300 bits per second. This innovation laid the groundwork for future advancements in modem technology and data communication.
What is meant by OSI modem?
An OSI modem refers to a modem that operates within the Open Systems Interconnection (OSI) model, which is a framework used to understand and implement network protocols in seven layers. Modems typically function at the physical layer (Layer 1) and the data link layer (Layer 2) of the OSI model, facilitating the modulation and demodulation of signals for data transmission over communication channels. Essentially, an OSI modem translates digital data from a computer into analog signals for transmission over phone lines or cable systems and vice versa.
When using a cable modem to connect to the internetthe data transmission shares the cabling with what other technology?
TV
Is modem is a data terminal equipment?
No, a modem is not classified as data terminal equipment (DTE); it is considered data communication equipment (DCE). DTE refers to devices like computers and terminals that generate or consume data, while DCE, such as modems, facilitates the transmission of data between DTEs over a communication channel. Modems convert digital data from a DTE into analog signals for transmission and vice versa.
When using a cable modem to connect to the internet the data transmission share cabling with what other technology?
Cable TV
What did the P C Modem invented By Dennis C. HayesDo?
The modem, which is short for modulator/demodulator, "packages" data according to a certain protocol for transmission to another computer, and it unpacks incoming data so the receiving computer can understand it.
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.
What is the process in which a user sends computer information from his computer to another computer through modem.?
The process of sending computer information from one computer to another through a modem is called data transmission. This involves the user encoding the data into a digital format, which is then modulated by the modem into a signal suitable for transmission over communication lines. The receiving modem demodulates the signal back into its original format, allowing the recipient computer to process the information. This entire process typically follows communication protocols to ensure data integrity and proper formatting.
