What is the difference between a modem and a codec?
* Codec is for coding analog data into digital form and decoding it back. The digital data coded by Codec are samples of analog waves. * Modem is for modulating digital data into analog form and demodulating it back. The analog symbols carry digital data.
What is the difference between analog and digital communications?
Analog means continuous transmission of data whereas digital means discrete transmission of data. In analog communications we are transmitting finite amount of data in infinite amount of information. so,there is a possibility of occurrence of noise. where as in digital we are transmitting finite amount of data in finite amount of information. so , out of these two, digital is most efficient.
Difference between analog and digital control systems?
An analog control system is one that presents data by measuring a continuous variable. This reports the data back in voltage or pressure.
What is the difference between bluetooth and wifi?
wifi is a wap (wireless access point (used for internet)) bluetooth is a data conecction (used 4 sending data)
What is difference between analog and digital data.how they different in their transmission?
Analog data differs in intensity. Digital consists of ones and zeros. Think of the difference as being like the difference between a drum and a violin. A drum is either on or off, and so is a piano. Although a violin does turn on and off, it constantly gives out information without turning on and off and it gradually goes between loud and soft. In a car, your speedometer is analog. Your headlights are digital. (They are either on or off) At one time they were transmitted differently. Analog data was sent by changing the height or frequency of a electronic sigh wave. Today, both are sent by a series of ones and zeroes. Then a receiver changes them back to analog or digital.
What is the difference between a digital phone and analog cordless phone?
Digital phones are more secure, can send both voice and data transmission, and has better sound quality. Analog phones are less expensive and only transmit voice.
What is data analog?
analog data are continuous and take continuous values
