To transfer data, the fiber optic wire used a high-speed data transmission medium, which includes a small glass or plastic polymers, that carry the light beam to transmit data through swift light flashes through the cable.
- It enables the transmission of data more quickly over larger distances.
- In this cable, the traditional cable use to provide web data transfer to cable TV, that why the given statement is true.
Answer:
for ( initialization; condition;increment)
{
code goes here;
}
in python:
for i in list/range:
code with proper indentation
By initialization above we mean, like int i=0; etc.
By condition like i<10;
and by increment it means like i++, ++i or i+=1; etc
And in python, i can be an integer value if the range is mentioned, and it can be an item of a list if the list is used. We can also use an array, string and various other data structures in python. like we can have characters in a string and so on.

Answer:
1. Classes and objects
2. Inheritance
3. Polymorphism
4. Data hiding/ encapsulation
5. Interfaces.
Explanation:
Classes and objects depict the major component of the OOP (object oriented programming). It explains the object like a ball in a soccer game development.
The inheritance is like the subclass of the object. Data hiding is a stage in oop where the codes or data are hidden from another users.
In the polymorphism stage, the object is given the ability to change to a sub-object, while in the interface stage a function or method signature is defined without implementing it.
