Carol purchases a computer. She installs speech recognition software on the computer.

Leno4ka [110]

B. Microphone helps Carol to use the speech recognition software.

Explanation:

A microphone is a hardware device which converts the sound waves in the air into electronic signals. The electrical signals are transferred to a recording medium. Four main types of microphones are as follows:

i) Cardioid

ii) Super cardioid

iii) Omni

iv) Figure 8

Handheld microphone can be used better with the home theater or a karaoke machine. The speech recognition software can be used with the help of microphone. Cabling problem can be avoided with the use of microphone, thus cable trip hazard can also be avoided.

To reduce the number of used digital outputs of the microcontroller, the display board is connected to the main board through th

Luda [366]

Answer:

The program in Python is as follows:

BCD = ["0001","0010","0011","0100","0101","0110","0111"]

num = input("Decimal: ")

BCDValue = ""

valid = True

for i in range(len(num)):

if num[i].isdigit():

if(int(num[i])>= 0 and int(num[i])<8):

BCDValue += BCD[i]+" "

else:

valid = False

break;

else:

valid = False

break;

if(valid):

print(BCDValue)

else:

print("Invalid")

Explanation:

This initializes the BCD corresponding value of the decimal number to a list

BCD = ["0001","0010","0011","0100","0101","0110","0111"]

This gets input for a decimal number

num = input("Decimal: ")

This initializes the required output (i.e. BCD value) to an empty string

BCDValue = ""

This initializes valid input to True (Boolean)

valid = True

This iterates through the input string

for i in range(len(num)):

This checks if each character of the string is a number

if num[i].isdigit():

If yes, it checks if the number ranges from 0 to 7 (inclusive)

if(int(num[i])>= 0 and int(num[i])<8):

If yes, the corresponding BCD value is calculated

BCDValue += BCD[i]+" "

else:

If otherwise, then the input string is invalid and the loop is exited

valid = False

break;

If otherwise, then the input string is invalid and the loop is exited

else:

valid = False

break;

If valid is True, then the BCD value is printed

if(valid):

print(BCDValue)

If otherwise, it prints Invalid

else:

print("Invalid")

Option D Use Amazon SQS to decouple the application components and keep the requests in queue until the extra Auto-Scaling instances are available.

Explanation:

Amazon SQS is a service that user to decouple the application components and keep the request in queue. This is useful to ensure the distribution of message can be done more reliably and without losing the message. Amazon SQS increase the system fault tolerance. Multiple duplicated copies of the message will be stored across several availability zones to ensure the message are always available whenever it is needed.
