A) It simplifies the process by providing a single user interface for multiple software tools.
Explanation:
Prototype is a working model for a product only for testing purposes
3. 8.1
Looking at the functions "average", and "mystery" it's pretty obvious that "average" returns a double precision average of the value of an integer array. The function "mystery" returns an array of integers with each value in the array being the length of the string in the array of strings passed to "mystery" in the same ordinal position.
The main body of the code initializes an array of strings and then passes that array to "mystery" who's output is then passed into the function "average". Since the lengths of the words passed to "mystery" is 7, 5, 6, 10, 10, 8, 13, 6, 8, 8, the sum will be 81, so the average will be 81/10 = 8.1 which matches option "3".
Answer:
In the context of cyber security, social engineering (SE) is a deceptive practice that exploits human <u>weaknesses </u> by inducing victims to interact with a digital device in a way that is not in their best interest. Many of these attacks begin with<u> spam</u> , which is defined as unsolicited messages that are usually sent in massive numbers using electronic mail systems. A spam <u>filter</u> uses a set of rules to examine email messages and determine which are spam. There are four common types of spam filters.<u> Content </u>filters examine the content within a message for certain words or phrases commonly used in spam emails.<u> Header</u> filters review the email header for falsified information, such as spoofed IP addresses. <u>Blacklist</u> filters block mail that originates from IP addresses of known spammers. <u>Permission </u> filters block or allow mail based on the sender's address. <u>Phishing</u> is an email scam that masquerades as a message from a(n) legitimate company or agency of authority, such as the IRS. <u>Pharming</u> redirects Web site traffic to fraudulent Web sites that distribute malware, collect personal data, sell counterfeit products, and perpetrate other scams. A rogue <u>antivirus </u> exploit usually begins with a virus warning and an offer to disinfect the infected device. Some software is not exactly malware, but it is a nuisance. A <u>PUA </u>takes up residence on a digital device and seems impossible to disable or remove.
Answer:
Time taken to travel from one track to the next = 0.08ms
Initial track= 15 0
4 (15-4)*(0.08)= 0.88
40 (40-4)*(0.08)= 2.88
35 (40-35)*(0.08)= 0.4
11 (35-11)*(0.08)= 1.92
14 (14-11)*(0.08)= 0.24
7 (14-7)*(0.08)= 0.56
----------------------------------------------
Total seek time=0.88+2.88+0.4+1.92+0.24+0.56=6.88ms
Explanation:
We caculate the seek time for each request, and then add them together to find the total seek time. The final track number for the current request becomes the current track of next request, and this process is repeated till the last request is processed.
