*Python Selenium Architecture has below components *
- Client Libraries
- Json Wire Protocal
- Browser Driver
- Real Browser
Client Libraries are the map to work with selenium directories, which will enable to work / communicate with selenium.
Client libraries provides necessary things for selenium to perform any action which then selenium will communicate with Json wire protocol.
Json Wire Protocol it convert into light weight data for communicating with browser driver.
Json wire protocol allows all respective drivers to communicate with their browser to perform an action.
Browser Driver acts as a bridge between libraries and browsers, every browsers has their own drivers which can be downloaded from web, eg., chrome browser has chrome driver, firefox browser has geckodriver and so on..
Browser driver communicate with real browsers.
Real Browsers - selenium supports different browsers like chrome, firefox, microsoft edge, safari, etc.. and supports on different operating systems like Mac, windows, linux..
and finally selenium API, which supports software to software interactions.
