What is meant by the phrase keying in?
The definition for "keying in" depends on the device being used. For telephones (including mobile phones), "keying in" information means using the numeric keypad to provide information (e.g., account number, spelling of last name, etc.). For calculators, "keying in" information means using the calculator keypad to enter numbers and execute operations on those values. For computers with a numeric keypad, "keying in" information means entering numbers into a particular program. For computers with a standard keyboard "keying in" information means typing in information.
HOW DO WE DIFFERENTIATE BETWEEN an input device and office data entry device?
An input device is any device that enables feeding of information into a computer, including office data entry devices. An office data entry device is one that is purely used for keying in data into a computer e.g. a mouse and a keyboard.
The shift keying process uses changes in voltage level of the carrier signal to represent the binary ones and zeros in the digital information signal?
Amplitude

What is amplitude shift keying modulation?
micxingthe between the phasr and frepaancy shift keying
Does the term WYSIWYG saves you the most time when keying a document?
WYSIWYG helps you save most of your when keying in a document.
What does the acronym 'BPSK' mean?
The acronym "BPSK" stands for burst pulse shift keying. Burst pulse shift keying is the simplest form of phase shift keying or PSK known currently to exist.
What is the difference between amlitude shift key and frequency shift key?
Amplitude shift keying changes the height/power of the transmitted signal without altering the frequency. Frequency shift keying changes the frequency of the transmission without altering the height/power of the transmitted signal. Morse code is an example of amplitude keying where the amplitude is 0 or 100%. RTTY teleprinter uses FSK with two frequencies and the codes that represent text characters are sent with patterns of the two frequencies.
What is the exact definition of differential phase shift keying?
differential phase-shift keying (′dif·ə′ren·chəl ′fāz ′shift ′kē·iŋ) (communications) Form of phase-shift keying in which the reference phase for a given keying interval is the phase of the signal during the preceding keying interval. Also known as differentially coherent phase-shift keying.Above retrieved from Answers.comViper1
