Answer:

The answer to this question can be described as follows:

Explanation:

Relational data model:

The use of data tables to organize sets of entities into relationships requires a relational data model. this model work on the assumption, which is a primary key or code, that is included in each table configuration. The symbol for "relational" data links and information is used by other tables.

Model Design:

This model is used for database management, it consists of structure and language consistency. It is design in 1969.

Importance of data model:

This provides a common standard for processing the potentially sound data in machines, that was usable on almost any one device.

What is segmentation and paging?

iogann1982 [59]

Over the years, operating systems have sought to be more efficient, which is why it is vital that the use of main memory such as ram be as intelligent as possible, so that operating systems are more efficient.

Segmentation is a process of dividing the program into logical units, such as sub functions, arrays, variables, etc., making it possible to have processes divided into pieces so that it is easy to access each of the processes that this leads to its execution. Segmentation allows the programmer to contemplate the memory as if it had several address spaces or segments. References to memory consist of an address of the form segment number - offset.

Pagination is a technique where memory space is divided into physical sections of equal size, called page frames. The programs are divided into logical units, called pages, that are the same size as the page frames. In this way, an information page can be loaded in any page frame. The pages serve as an information storage unit and transfer between main memory and auxiliary or secondary memory. Each frame is identified by the frame address, which is in the physical position of the first word in the page frame.

Tems11 [23]

Answer:

Explanation:

I do not have the files listed in the question so I have made two test files with the same names. This code is written in Python, we are assuming that the names on each file are separated by newlines.

f1 = open("GirlNames.txt", 'r')

f1_names = f1.read()

f1_names_list = f1_names.split('\n')

f2 = open("BoyNames.txt", 'r')

f2_names = f2.read()

f2_names_list = f2_names.split('\n')

print(f1_names_list)

print(f2_names_list)

boy_or_girl = input("Would you like to enter a boy or girl name or both: ").lower()

if boy_or_girl == 'boy':

name = input("Enter name: ")

if name in f2_names_list:

print("Yes " + name + " is in the list of most popular boy names.")

else:

print("No, it is not in the list")

elif boy_or_girl == 'girl':

name = input("Enter name: ")

if name in f1_names_list:

print("Yes " + name + " is in the list of most popular girl names.")

else:

print("No, it is not in the list")

elif boy_or_girl == 'both':

girlname = input("Enter Girl name: ")

if girlname in f1_names_list:

print("Yes " + girlname + " is in the list of most popular girl names.")

else:

print("No, it is not in the list")

boyname = input("Enter name: ")

if boyname in f2_names_list:

print("Yes " + boyname + " is in the list of most popular girl names.")

else:

print("No, it is not in the list")

else:

print("Wrong input.")
