Answer:
When there's a comparison between binary files with diff, there's a message from the utility that says there's a difference when the files differ or there's no message when the two are same. ASCII files comparison is made by the diff utility line-by-line. there's no provision to make comparisons on a byte by byte basis. in that case use cmp.
Explanation:
Answer:
E = b-a
Explanation:
In this questions what we are been asked is for the expected value E, to solve the problem we need to recognize the random variables and their respective probability.
- x1 = roll a 1 -> P1 = 1/6
- x2 = roll a 2 -> P2 = 1/6
- x3 = roll a 6 -> P3 = 1/6
- x4 = roll a 1, 4 or 5 -> P4 = 1/2
E = P1*x1 + P2*x2 + P3*x2 + P4*x4
x1 is equal to zero (no points and the game stop), x2 is equal to E-a (lose a points, affecting the expected value), x3 is equal to E+b (win b points, affecting the expected value) and x4 is equal E (no points are lost and the game continues, therefore the expected value is not affected)
E = 1/6*0 + 1/6*(E-a) + 1/6*(E+b) + 1/2*(E)
1/6*E = 1/6*b - 1/6a
Solving for E
E = b-a
Conclusion: If you get a 3, 4 or 5 the game is unaffected (in terms of points), you need to pay special attention to x1, x2 and x3 (all with the same probability) that are the results that are going to affect your game.
Answer: ensuring that a system is not changed by a subject that is not authorized to do so
Explanation: Access control refers to pribcues which are employed in the bid thlo ensure the security of data and information. It provides the ability to authenticate and authorize access to information and data thereby preventing unwarranted access and tampering of the information. Integrity in terms of data security and access control is is concerned with modification to an existing or original data by unauthorized sources. When unauthorized addition or subtraction occurs on a data, the integrity of such data has been compromised. Therefore, authorization is required whenever a source is about to access certain information whereby only those with the right authorization code will be allowed, Inputting an incorrect pass code after a certain number of tries may result in system lock down as access control detects a a possible intrusion
Answer: Business intelligence(BI) system is the tool that is used in the business field through companies and organization. The main cause of using BI system because it acts as the collection of the methods and technologies that help in the changing the raw and rough data to useful information which improves the functioning of the organization.
It provides better functioning by identification of the appropriate data,managing the information and making it efficient in a manner to make it presentable. These features make the organization to easily access the data and improves operations.
