The department store should consider using RFIDs (Radio Frequency Identification) for tracking inventory. Unlike the wireless barcodes, RFID uses radio waves to communicate with readers. One very common advantage of an RFID is the scanning range. Wireless barcodes, for instance, requires the reader to be close to the barcode before it can see it to scan it. However, RFID systems can scan a tag as long as it is within range. This is important because it reduces wastage of time on labor-intensive processes and increases task speed, convenience, and project turnover.
Many passive RFIDs use tags that are powered by electromagnetic energy. Such energy does not consume power.
Answer:
Following are the program in Python langauge
person_name = input() # Read the person name by the user
person_age=0 #declared a vaiable person_age
person_age = int(input()) # read person_age by the user
person_age=person_age+5 # add 5 to person_age
print('In 5 years',person_name,'will be',person_age) # display the output
Output:
Amy
4
In 5 years Amy will be 9
Explanation :
Following is the description of code:
- Read the value of the "person_name" variable by the user by using the input function.
- Declared a variable person_age and initialized 0 with them.
- Read the value of "person_age" variable by user by using input function and convert into int by using int function
- Add 5 to "person_age" variable and store again them into the "person_age" variable.
- Finally, display the output which is mention in the question.
Answer:
True
Explanation:
If s=abcd is a string defined over {a,b,c,d}, it corresponds to a regular expression which can be represented using a finite automata. Then the reverse of the string essentially corresponds to another finite automata where the starting state becomes the accepting state and vice versa.Moreover all the directions of state transitions will be reversed for each of the transitions in the original automata.
With these modifications, the new finite automata will accept a string which is reverse of the original string ,namely, dcba and this string will ne part of the reverse language.
Answer:
18, 13, 19
Explanation:
Number of computer programmers proficient only in Java = 45 - ( 1+1+6) = 37
Number of computer programmers proficient only in C++ = 30 - (6+1+5) = 18
Number of computer programmers proficient only in python = 20 - ( 1+1+5) = 13
Number of computer programmers are not proficient in any of these three languages = 100 - ( 37 + 18 + 13 + 1+ 1+ 5+ 6 ) = 100 - 81 = 19
