Modem full form in computer

(m dem) (n.) Short for modulator- demodulator. A modem is a Standard Modem Interface The Early telelphone modems used a RS-232. Consequently, any external modem can be attached to any computer that has an RS-232 onboard or internal modems. Protocols for Formatting Data While the modem interfaces are standardized, a number of different Aside from the transmission protocols that they support, the following characteristics distinguish one modem from another: • bps : How fast the modem can transmit and receive data. At slow rates, modems are measured in terms of • voice/data: Many modems support a • auto-answer :An auto-answer modem enables your computer to receive calls in your absence. This is only necessary if you are offering some type of computer service that people can call in to use. • data compression :Some modems perform data compression, which enables them to send data at faster rates. However, the modem at the receiving end must be able to decompress the data using the same compression technique. • flash memory : Some modems come with flash memory rather than conventional • fax capability: Most modern modems are To get the most out of a modem, you should have a package,a program that simplifies the task of transferring data.

Modulation Demodulation - A modem( 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. Modems can be used over any means of transmitting analog signals, from light emitting diodes to radio. The most familiar example is a voice band modem that turns the digital data of a personal computer into modulated electrical signals in the voice frequency range of a telephone channel. These signals can be transmitted over telephone lines and demodulated by another modem at the receiver side to recover the digital data. Modems are generally classified by the amount of data they can send in a given time unit, normally measured in bits per second (bit/s, or bps). They can also be classified by the symbol rate measured in baud, the number of times the modem changes its signal state per second. For example, the ITU V.21 standard used audio frequency-shift keying, aka tones, to carry 300 bit/s using 300 baud, whereas the original ITU V.22 standard allowed 1,200 bit/s with 600 baud using phase shift keying.

The correct answer is Modulator-Demodulator. Key Points Modem: • It acts as a bridge between the internet/telephone line and the computer. • It maintains a dedicated connection with the ISP to get the internet conn ection for home or business. • The reason to use the modem for an internet connection is that both the internet and the computer take two different signals. It means that the internet sends the analog signal, but the computer system can only understand the digital signal. • So, we need a device that can convert an analog signal to a digital signal and vice versa. To do this, we need a modem. • A modem modulates the incoming analog signal from the internet to a digital signal and directs it to the computer, and vice versa. That is why it is called a device that modulates or demodulates the signal or MODEM.

Dennis Hayes’s company, Hayes Microcomputer Products, is a modem manufacturer. His company’s Hayes Command Set is widely used in most modern-day modems. 3 Facts About The Modem • “Modem” is an abbreviation of the device’s function, which is to act as a modulator-demodulator for data signals traversing analog and digital networks. • As the product evolved, the transfer speeds increased not only because of the actual transfer rate, but also because of the protocols used to transfer data. Eventually data compression was used which helped move data faster while not having to increase the bit/s rate. • The modulator-demodulator was initially used by news agencies to send data faster. Over time it served the United States during the Cold War, and eventually became a household item as computers and the Internet became more popular among society. AT&T’s modem from 1958 Quick Facts Created The earliest form of a modem in its true sense was created in the 1920’s. Creator While the concept for the modem had been around since the 1920’s, the first modem made specifically for personal computers was invented by Dale Heatherington and Dennis Hayes. Original Use The modem has always been used to convert analog data into a digital format, and vice versa. Cost Different brands and types of modems have been sold throughout the years at varying costs. Modem History The earliest types of modems have been around since the 1920’s. Back then the main function of a modem was to transmit data types...

MODEM Full Form What Is The Full Form Of MODEM? Modem stands for Modulator-Demodulator. It is a device that converts digital data from a computer or other digital device into an analog signal that can be transmitted over a telephone or cable line, and then converts the analog signal back into digital data at the receiving end. The modem is the essential component that allows computers to communicate over telephone or cable lines. The modem converts the digital data from the computer into an analog signal that can be transmitted over the telephone or cable line. The modem also converts the analog signal back into digital data at the receiving end, so that the computer can understand the information that was sent. Modems come in a variety of speeds, with the most common being 56kbps, which is the fastest speed available for telephone lines. Cable modems, which use cable television lines to transmit data, can be much faster, with speeds up to 100Mbps or more. The faster the modem, the more quickly data can be transmitted. Modems can be either external or internal. External modems connect to the computer through a serial or USB port, while internal modems are built into the computer and connect to the motherboard. External modems are typically easier to install and troubleshoot than internal modems, but internal modems take up less space and are generally more reliable. Modems can also be classified by their type of connection: dial-up or broadband. Dial-up modems use telephon...
