Complete Question:
Recall that with the CSMA/CD protocol, the adapter waits K. 512 bit times after a collision, where K is drawn randomly. a. For first collision, if K=100, how long does the adapter wait until sensing the channel again for a 1 Mbps broadcast channel? For a 10 Mbps broadcast channel?
Answer:
a) 51.2 msec. b) 5.12 msec
Explanation:
If K=100, the time that the adapter must wait until sensing a channel after detecting a first collision, is given by the following expression:
The bit time, is just the inverse of the channel bandwidh, expressed in bits per second, so for the two instances posed by the question, we have:
a) BW = 1 Mbps = 10⁶ bps
⇒ Tw = 100*512*(1/10⁶) bps = 51.2*10⁻³ sec. = 51.2 msec
b) BW = 10 Mbps = 10⁷ bps
⇒ Tw = 100*512*(1/10⁷) bps = 5.12*10⁻³ sec. = 5.12 msec
Answer:
nrToCheck = int(input("How many numbers do you need to check? "))
nrEven = 0
nrOdd = 0
for i in range(nrToCheck):
number = int(input("Enter number: "))
if (number % 2):
nrOdd = nrOdd + 1
print("{} is an odd number".format(number))
else:
nrEven = nrEven + 1
print("{} is an even number".format(number))
print("You entered {} even number(s).".format(nrEven));
print("You entered {} odd number(s).".format(nrOdd));
Answer:
In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" (zero) and "1" (one). The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit, or binary digit.
Explanation: and the key to reading binary is separating the code into groups of usually 8 digits and knowing that each 1 or 0 represents a 1,2,4,8,16,32,64,128, ect. from the right to the left. the numbers are easy to remember because they start at 1 and then are multiplied by 2 every time.
Answer:
<HTML> tag
Explanation:
The first tag in any HTML file is the <HTML> tag. This tells web browsers that the document is an HTML file
