Answer 1

But after this i cannot type anything in command prompt

The program that waits for your input is called shell and when you type ng serve this shell program runs ng program and passes control to ng . ng doesn't expect any input from you so you can't type in anything. In order to be able to input again you have to:

1. either exit ng and pass control back to shell by pressing Ctrl+C , but this stops ng program.
2. run ng serve in background - START /B ng serve for Windows and long-ng serve & for Unix environments

See this answer for running programs in background in Windows.

Answer 2

From a web browser open http://localhost:4200

To kill the ngCli development server use ctrl+c in the command prompt.

You won't be able to run other commands in the command prompt while the development server is running. Simply open another command prompt to run other tasks.
