Answer:
False
Explanation:
Moore's law observes the principle that the computing speed and capability of computers doubles after every two years, because of increases in the number of transistors a microchip can contain. This increase in coputational power will rather help banks and e-commerce sites (the defenders) much more than it will help the attackers. This is so because cryptographic systems are designed so that a small amount of extra work by the defender leads to an much much greater amount of work for the attacker.
Answer:
def cost(quantity, unit_price, taxable):
if taxable == "Yes":
total = (quantity * unit_price) + (quantity * unit_price * 0.07)
elif taxable == "No":
total = quantity * unit_price
return total
q = int(input("Enter the quantity: "))
p = float(input("Enter the unit price: "))
t = input("Is %7 tax applicable? (Yes/No): ")
print(str("$" + str(cost(q, p, t))))
Explanation:
- Create a function called cost that takes three parameters, quantity, unit price, and taxable
- If the tax is applicable, calculate the total with tax. Otherwise, do not add the tax.
- Return the total
- Ask the user for the inputs
- Call the function with given inputs and print the result
Answer:
1. Scanner = reading passports.
2. Barcode reader = automatic stock control.
3. pH sensor = monitor soil in a greenhouse.
4. Microphone = voice recognition.
Explanation:
1. Scanner: Copies paper documents and converts the text and pictures into a computer-readable form. Therefore, it can be used for reading passports.
2. Barcode reader: reads labels containing parallel dark and light lines using laser light or LEDs; the width of each line represents a binary code. Therefore, it is used for automatic stock control.
3. pH sensor: detect changes in acidity levels; data is often in analogue form. Thus, it is typically used to monitor soil in a greenhouse.
4. Microphone: allows audio signals to be converted into electric signals; these can be interpreted by a computer after being converted into digital form. Microphones are used for voice recognition.
