a lot of how an operating system works depends on the underlining
true or false
Answers
The operating system (OS) of the computer manages all of the hardware and applications. The basic functions it performs include processing input and output, managing files, memory, and processes, and controlling peripheral devices like disk drives and printers.
What elements impact how users perceive the operating system?Users' perceptions are influenced by the system interface they use. Some systems are designed so that a single user can fully utilize all of the resources to focus on their work. In these cases, the OS places little to no attention on quality and resource efficiency and is primarily designed for user-friendliness.
What factors influence an operating system's effectiveness?A number of hardware problems, such as those affecting the system's data and address buses, including their size and speed, might limit the performance of the overall system. The model, clock rate, and internal level-one (L1) memory cache size of the CPU or CPUs in the system.

True. Each page within a website/domain typically has a unique URL (Uniform Resource Locator) that identifies its specific location on the internet.
The URL serves as an address for accessing and referencing a specific webpage, allowing users to navigate to different pages within a website or SHARE the URL to direct others to a particular page.A URL (Uniform Resource Locator) is a specific web address that is used to locate and access resources on the internet. It provides a standardized way to identify the location of a web page, file, or any other resource. A URL consists of several components:1. Protocol: The protocol specifies the rules and procedures that determine how data is transferred between the client (web browser) and the server. Common protocols include HTTP (Hypertext Transfer Protocol), HTTPS (HTTP Secure), FTP (File Transfer Protocol), etc.
2. Domain Name: The domain name identifies the specific website or server hosting the resource. For example, in the URL "https://www.example.com," "www.example.com" is the domain name.
3. Path: The path specifies the specific location or directory within the website where the resource is located. It follows the domain name and is separated by slashes (/). For example

what benefit does udp have over tcp? question 14 options: efficiency error correction retransmission error detection
Answers
UDP (User Datagram Protocol) has several benefits over TCP (Transmission Control Protocol). One key benefit is efficiency. UDP is a lightweight protocol that does not require the establishment of a connection before data transmission. This makes it faster and more efficient for sending small, time-sensitive packets of data.
Another benefit of UDP is that it does not provide error correction or retransmission of lost packets. While this may seem like a disadvantage, it actually makes UDP ideal for applications where speed is more important than data accuracy, such as real-time streaming or online gaming.
Additionally, UDP does not perform error detection at the transport layer. In summary, the benefits of UDP over TCP include efficiency, lack of error correction and retransmission, and lower latency.

If the price of netflix decreases, what will happen in the market for hulu? (assume netflix and hulu are substitute goods.)
Answers
If the price of Netflix decreases, it is likely to have an impact on the market for Hulu. As Netflix and Hulu are substitute goods, a decrease in the price of Netflix would lead to a shift in consumer preferences towards Netflix, resulting in a decrease in the demand for Hulu.
When the price of a substitute good decreases, consumers tend to switch their consumption towards the cheaper alternative. In this case, with Netflix becoming relatively more affordable, consumers are likely to choose Netflix over Hulu, leading to a decrease in the demand for Hulu. As a result, the market for Hulu may experience a decrease in sales and a potential decrease in its market share.
However, the magnitude of the impact on Hulu's market will depend on several factors, including the extent of the price decrease of Netflix, the strength of consumer preferences for each platform, and the availability of other substitute goods in the market.

Write a class called Student.
Class Student must use private variables to store the following attributes for each student
- name
- surname
-mark
The values for name and surname must be set using an __init__ method when the class is first created. Mark should default to the value 0 until it is set by the user.
All three the above attributes should only provide access to the underlying data via appropriate get and set methods. However, the set methods for name and for surname should not change the value to these fields. Instead, any attempt to change the name or surname for a student object should be ignored and a message stating either "Student name changes are not allowed!" or "Student surname changes are not allowed!" should be displayed if the user tries to change these values.
The property for mark should only allow the user to set it number values between 0 or 100. If the user tries to enter a mark that is outside these boundaries the mark should remain unchanged and a message should be printed stating "Mark must be between 0 and 100"
In addition to the above, the class should have a single function called get_result
This method should be a function that returns a single capital letter representing the student's grade mark symbol for their mark. The following applies:
Grade mark symbols
A
Mark >= 90
B
Mark >= 80
C
Mark >= 60
D
Mark >= 50
E
Mark >= 40
F
Mark < 40
For example:
Test
Result
s1 = Student("Joe", "Black")
print(s1.name)
print(s1.surname)
Joe
Black
s2 = Student("Sue", "Brown")
s2.mark = 39
print(s2.get_result())
s2.name = "Test"
print(s2.name + ' ' + s2.surname + ' has a mark of ' + str(s2.mark))
F
Student name changes are not allowed!

PYTHON CODE ONLY
Answers
The given task requires implementing a class called "Student" with private variables for name, surname, and mark. The class should have getter and setter methods for accessing and modifying the attributes. However, attempts to change the name or surname should be ignored, and a message should be displayed.
The mark attribute should only allow values between 0 and 100, and an appropriate message should be printed if an invalid mark is entered. Additionally, the class should have a method called "get_result" that returns the grade mark symbol based on the student's mark. Here is the Python code that implements the class "Student" with the desired functionalities:
class Student:
def __init__(self, name, surname):
self.__name = name
self.__surname = surname
self.__mark = 0
def get_name(self):
return self.__name
def get_surname(self):
return self.__surname
def get_mark(self):
return self.__mark
def set_mark(self, mark):
if 0 <= mark <= 100:
self.__mark = mark
else:
print("Mark must be between 0 and 100")
def get_result(self):
if self.__mark >= 90:
return "A"
elif self.__mark >= 80:
return "B"
elif self.__mark >= 60:
return "C"
elif self.__mark >= 50:
return "D"
elif self.__mark >= 40:
return "E"
else:
return "F"
name = property(get_name, None, None, "Student name changes are not allowed!")
surname = property(get_surname, None, None, "Student surname changes are not allowed!")
mark = property(get_mark, set_mark, None, "Mark must be between 0 and 100")
In the above code, the class "Student" is defined with private variables for name, surname, and mark. The getter methods (get_name, get_surname, and get_mark) allow access to the respective attributes. The set_mark method checks if the mark is within the valid range (0 to 100) before updating it. The get_result method returns the grade mark symbol based on the student's mark.
To restrict changes to name and surname, properties are used. The properties for name and surname provide the getter methods but do not allow setting a new value. Instead, a message is displayed to indicate that changes are not allowed. Similarly, the property for mark allows both getting and setting, but if an invalid mark is provided, an appropriate message is printed, and the mark remains unchanged.

[This initialises c to 0]
c = 0
[The following iteration is repeated as long as c is less than 10]
while (c < 10):
[This increments c by 5]. Recall that c is initially 0. Hence, c becomes 0 + 5 = 5
c = c + 5
[This prints the value of c which is 5]
print(c)
The iteration is then repeated because the condition is still true i.e. 5 is less than 10
c = c + 5 = 5 + 5 = 10
[This prints the value of c which is 10]
print(c)
The iteration won't be repeated because the condition is now false i.e. 10 is not less than 10.
Hence, the output is 5 and 10.
