R installation version
I had installed R version 4.0.5. While I open the R console it doesn't match with the tutorial. In that tutorial, the Working environment divided into 2 parts, one for R console, and another one for Environment and history tab and also it contains the file which contains the current working data frames. But while I opened the R environment it only contains the console. My doubt is where I can find the history tab and environment tab.

You need to install RStudio along with R. RStudio is a friendly UI for R and it contains all of the tabs which you are looking for. Kindly refer to the following link to install RStudio - https://www.rstudio.com/products/rstudio/download/
