Lydia used software to calculate the budget for each department. To create this budget, she used a spreadsheet.
Answer:
So, 11001000 is the binary equivalent of decimal number 200 (Answer).
1) You don't know if the source is reliable.
2) It is better to cite reliable sources so.
Answer:
The answer is "Option D".
Explanation:
Trojan program is a malicious code that is also known as a virus. It is a rootkit, that aims to infect the computer to hide or obscure an object. These programs are mainly used to download additional content, such as additional pieces of malware, to the infected computer, and other options are wrong that can be defined as follows:
- In option A, It is not correct, this option infects the system.
- In option B, It is used for infects another computer that's why it is incorrect.
- In option C, It is incorrect because it is used in cybersecurity.
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.
