Answer:
The correct answer is: 255.255.255.192.
Explanation:
A subnet mask complements an Internet Protocol (IP). Thanks to subnet masks IP addresses can be identified because they seem to be all the same but the subnet mask avoids confusion. If four subnets are to be created for the IP 192.168.90.0 3 bits of that IP must be used to create the subnet resulting in 255.255.255.192. Then:
- <em>Number of subnets</em>:

- <em>Number of hosts per subnet</em> =

Answer:
The correct option is Option C: It matches a new problem with a previously solved problem and its solution.
Explanation:
Case-based reasoning (CBR) is used when someone tries to solve new problems based on old problems that were similar. The person applying case-based reasoning would look for the solutions to these similar past problems and try to apply them to the new case. For example, a doctor who tries to treat a patient based on what was successful with a prior patient with a similar problem is applying case-based reasoning. In some instances, these problems are available in a database and ideally, that is how it is conceived, but it would depend on the field and the kind of problems. There is no universal global network dedicated to CBR as a whole (other than generic searches on the internet in general). One example of a specific CBR database is the European Nuclear Preparedness system called PREPARE.
Solution :
Public Function Is a Leap_Year(Year As_Integer) As Integer
'Dim Tor_F for local variable declaring if value is t/f.
Dim TorF As For Boolean
'Pre conditions: Year > 1581 and Year < 3000
If Year > 1581 And Year <> 1700 Or 1800 Or 1900 Then
IsLeapYear = Year / 4
Else
IsLeapYear = False
TorF = False
End If
End Function
I would suggest the use of a
disk quota.
Using a disk quota would limit the available space that
users could have used to store data. The New Technology File system (NTFS) has
several features like disk quotas to see which users are uploading the most
space. The windows interface Open
Computer Management is also another option that limits the number of users of a
shared folder.
