There are multiple devices that emit radio waves. The most obvious is are radiod and microwaves (yes, the food cooker). Wireless applicances also emit radio waves. But don't confuse everything to use microwaves. Some applicances use frequencies instead of radio waves. Some applicances that use frequencies are toy control remotes and a garage door.
I hope this helps! Please make sure ask me if you need more clarity!
# Written in python
a = int(input("Enter an integer: "))
b = int(input("Enter an integer: "))
sum = a + b
# subtract the smaller number from the bigger
if a < b:
dif = a - b
else:
dif = b - a
prod = a * b
print("The sum is", sum)
print("The dif is", dif)
print("The product is", prod)
Technical skills is when you are advanced or know lots in Electronics. You are able to diagnose problems and fix them. They help in the computer field so much because they help fix everything if no one had these skills we wouldn’t be able to even use brainly
