Which of the following performs modulation and demodulation?
-
Fiber optics
-
Satellite
-
Coaxial cable
-
Modem
Correct Answer
A. ModemExplanation
A modem performs both modulation and demodulation. Modulation is the process of converting digital signals into analog signals for transmission over a communication channel. Demodulation, on the other hand, is the process of converting analog signals back into digital signals for reception. A modem allows computers to transmit and receive data over various communication channels, such as telephone lines or cable lines, by modulating and demodulating the signals. Therefore, a modem is the correct answer as it is the device responsible for performing both modulation and demodulation.Rate this question:

Which data type is better to use for storing phone number in the following format “977-1-1234567”?
-
Text
-
AutoNumber
-
Number
-
Currency
Correct Answer
A. TextExplanation
The phone number format "977-1-1234567" contains hyphens and is not a numerical value, so it cannot be stored as a Number or Currency data type. The Text data type is more suitable for storing this format as it allows for the inclusion of non-numeric characters like hyphens. The AutoNumber data type is not applicable in this case as it is used for generating unique, sequential numbers for record identification, not for storing phone numbers.Rate this question:

Which criteria do not return the position “Officer” as a match?
-
Position = “*ff*”
-
Position = “O??icer”
-
Position = “ ?ff*”
-
Position = “O#r”
Correct Answer
A. Position = “O??icer”Explanation
The criteria "position = “O??icer”" does not return the position "Officer" as a match because the question marks in the criteria represent wildcard characters that can match any single character. Therefore, the question marks in the criteria can match any character in the position string, but the actual position string "Officer" has specific characters ('f' and 'i') in those positions, which do not match the wildcard characters in the criteria.Rate this question:
