<span>a. DA
Given the question and available options, this looks like a question about Ethernet frames. So let's look at the options and see what makes sense.
a. DA
* DA - Destination address. And the question pretty much defines what it is. So this is the correct choice.
b. SA
* SA - Source address. This is the physical address that the frame was sent from. And since the question is mentioned who the frame is intended for, this is obviously the wrong choice.
c. SFD
* SFD - Start Frame Delimiter. This is a special CONSTANT sequence of bits that terminates the preamble. It's purpose is to indicate the start of the frame payload. Since it's a constant value, it does not indicate in any way where the frame is intended to go. So this is a bad choice.
d. Preamble
* Preamble - is a pattern of alternating 0 and 1 bits intended to synchronize receivers so that the rest of the frame is interpreted correctly. This too is a constant value and as such can't indicate the destination of the frame, so it's a bad choice.</span>
Answer:
I dont know about 1800 words but I sure can tell you abit about array
Explanation: Array in simple sense refers to a collection of similar data. It holds data which is homogeneous in nature, meaning they are all alike. The use of array provide a lot of advantages in the fields of computer programming. When you declare a variable for an array, you can store as much data as you wish in the same variable without having to declare many variables. A 2X2 dimensional array can also be used in programming which represents matrices as well. The search process in an array too is really convenient and time saving. Also in an array, accessing an element is very easy by using the index number.
R₂ and R₃ can be replaced by:
The total R of the circuit is R₁+R₅+R₄ = 706 2/3
So the current in the circuit I=V/R is 100/(706 2/3) = 15/106 A
(I'm deliberately not trying to round the result)
The voltage drop over R₄ is V=I*R = 15/106 * 500 ≈ 70
So answer C would be my choice.
Error-correcting code memory
def recursiveFactorial(number):
if number > 0:
return number * (recursiveFactorial(number - 1))
else:
return 1
stringNum = input("Enter a positive integer: ")
num = int(stringNum)
print(recursiveFactorial(num))
I hope this helps!
