RE: the characters entered through keyboard gets conve...
Not exactly the keys from the keyboard are not directly converted to ASCII values keyboard generated a specific key code for every key pressed which is not the ASCII equivalent of that key. This keycode is then trapped by the OS which has a Key Table with it which has the mapping for the Key Code and its corresponding ASCII code . We are generally using QWERT style keyboards the keycode for A on QWERTY style keyboard might be different than a DOVARK style keyboard. It is the responsibility of the OS to make that transparent for us.

RE: the characters entered through keyboard gets converted to equivalent ASCII code & stored on RAM in the binary form. What is exact procedure to happens on hardware that converts the ASCII value to equivalent binary form?
The keyboard itself sends a binary signal to the keyboard driver of the OS which then interprets the signal from the keyboard as the OS sees fit - in Windows these values are generally stored as 2-byte ANSI Unicode values based on the language code page in use.
