Answer
First part:
The transmitted 8-bit sequence for ASCII character '&' with odd parity will be 00100110. Here leftmost bit is odd parity bit.
Second part:
The invalid bit sequence are option a. 01001000 and d. 11100111
Explanation:
Explanation for first part:
In odd parity, check bit of either 0 or 1 is added to the binary number as leftmost bit for making the number of 1s in binary number odd.
If there are even number of 1s present in the original number then 1 is added as leftmost bit to make total number of 1s odd.
If there are odd number of 1s present in the original number then 0 is added as leftmost bit to keep the total number of 1s odd.
Explanation for second part:
A valid odd parity bit sequence will always have odd number of 1s.
Since in option a and d, total number of 1s are 2 and 6 i.e. even number. Therefore they are invalid odd parity check bit sequences.
And since in option b and c, total number of 1s are 5 and 7 i.e. odd numbers respectively. Therefore they are valid odd parity check bit sequences.
Answer:
the HTML tag for the paragraph is <p>.
Explanation:
To insert the paragraph in the website, use the <p> tag to start the paragraph and to end the paragraph, use the closing paragraph tag that is </p>.
The paragraph tag is used inside the body tag. for example,
<html>
<head></head>
<body>
<p>this is a paragraph
</p>
</body>
</html>
The answer is A) Double.
The return type is specified before the method's signature, and the signature is composed of the the method's name and parameters.
In this case, the method is named mynewFunction, takes in an integer as a parameter, and returns a double.
Also, fun fact which is kind of unrelated: if two or more methods have the same name, they can have different functionality as long as their signature is different (different parameter types).
Answer:
Your computer now has the IP address of that website cached, and no longer has to lookup the IP address of that domain name. The TTL of the first query is bigger than the TTL of the second query as less time was taken to execute the request.
Explanation:
On the first request to the website, the computer needs to contact other machines to find the record of the IP address.
On the second request, the computer already has the IP address and can use that to connect.
