DOM ( Document Object Model ) The DOM is like a map of a webpage or document. Imagine a webpage (HTML) as a tree where each part—like headings, paragraphs, buttons, or images—is a branch or a leaf. The DOM is the structure of this tree that makes it easy for programs to understand and interact with the webpage. ...

Electro Magnetic Field Learning about Electronics , signals , communication Communication Communication is sending information from one place to another. In wireless communication, we don’t use wires or cables — instead, we use waves to send information. Wave is simply a way to move energy or information from one place to another. Imagine throwing a pebble in a pond, ripples carry energy outwards Waves in communication work in a similar way, but instead of water, they travel through air or space. ...

Google doc link Async Programming Basics of Async Programming At any single time, a single CPU thread executes only a single function ( no multiprocessing happens ) atleast in the case of python !! Its just smart switching Pick up a event loop / create a event loop Create / Add tasks in it Check for the status and if done return the result Coroutines : A coroutine is a special function that can give up control to its caller without losing its state. ...

Activation / Non-linear function A non-linear function is one in which cannot be expressed from y = mx + c lets suppose a function with y = x * W1 * W2 .. Wl Linearity with respect to x, this means rest of the variable are constant and only x is changing , so linearity with respect to x is linear Linearity with respect to Wi, this means rest of the variable (x here) is constant and only weights are changing , so linearity with respect to W is non-linear ...
