Two forms of compression are lossy and lossless. State giving reasons which

Computers and Technology
1 answer:
Helen [10]3 years ago
4 0

Answer:

(i) When transmitting a draft manuscript for a book, the lossless compression technique is most suitable because after decompression, the data is rebuilt and restored in its form as it was from where it originated

(ii) When transmitting a video recording which you have made of the school play, a lossy compression technique is most suitable because the large size of video files require the increased data carrying capacity which is provided by the lossy transmission technique. The quality of the video can be reduced without affecting the message intended to be delivered

Create a base class named rectangle that contains lenght and width data members.
kumpel [21]

Answer:

class Rectangle:  

   

   def __init__(self, length, width):

       self.length = length

       self.width = width

       

   

   def area(self):

       area = self.length*self.width

       return area

   

   

class Box (Rectangle):

   

   def __init__(self, length, width, height):

       super().__init__(length, width)

       self.height = height

       

   def volume(self):

       volume = self.length * self.width * self.height

       return volume

   

   def area(self):

       area = 2*(self.length*self.width) + 2*(self.length*self.height) + 2*(self.width*self.height)

       return area

rec_1 = Rectangle(2,4)

box_1 = Box(2,2,6)

print(box_1.length)

print(box_1.area())

   

print(rec_1.length)

print(rec_1.area())

Explanation:

The programming language used is python.

class Rectangle

The class Rectangle is created with attributes length and width.

The class attributes are initialized using the __init__ constructor.

In the rectangle class, a method/function is declared to return the area of the rectangle.

class Box

This class is a child of rectangle and it inherits all its attributes and methods,

It has an additional attribute of depth and its constructor is used to initialize it.

The class contains a volume function, that returns the volume and an override function 'area()' that displaces the area from the parent class.

Finally, some instances of both classes are created.
