Answer: False
Explanation:
This means that the mappings between the two schemas may be specified in either one of these languages.In most relational DBMSs today, there is no specific language that performs the role of SDL. Instead, the internal schema is specified by a combination of functions, parameters, and specifications related to storage. These permit the DBA staff to control indexing choices and mapping of data to storage
Answer:
mylist = [ ]
for i in range(7):
mylist.append (int(input("Enter the number of bugs for each day ")))
print(mylist)
print("The highest number of bugs is ")
print(max((mylist)))
Explanation:
- Create and Initialize an empty (mylist)
- Using the .append method, we request and add the bugs for each day into the list
- print out the list
- Use the max function to find the highest number of bugs in the list and print it out

Answer:
Explanation:
Given a class C IP address
195.1.1.0
Existing mask is 255.255.255.0
We want to have 12 hosts on 10 subnets.
A class C address has 8 bits of the host which will give, n=8
2ⁿ - 2 = 254 hosts
Current mask= 255.255.255.0
Bits needs for 10 subnets
2ⁿ = 10, n = 4bits
n = 4 = 2⁴ = 16 possible subnets
Now, bit needed for 12host, n =4bits
2⁴-2 = 14 possible host,
Total of 8 bits needed so therefore we can use as 4bits for the subnet.
So we could have
4 bit subnet and 4 bits hosts
11110000 = 240decimals
Final possible masks is
255.255.255.240
