Why angular packages are separated and why we need them

I started creating a new angular 2 application. I looked through the articles and downloaded some free applications from github, all of them have the angular / comman package along with some other packages. I installed the angular package and added "angular": "^1.6.5"to the package.json file. I'm not sure if we can have a complete package, then why do we install the command package separately?

When I checked another application, they basically have the following

"@angular/common": "2.0.1",
"@angular/compiler": "2.0.1",
"@angular/core": "2.0.1",
"@angular/forms": "2.0.1",
"@angular/http": "2.0.1",
"@angular/platform-browser": "2.0.1",
"@angular/platform-browser-dynamic": "2.0.1",
"@angular/router": "3.0.1",

Are they all part of the angular core? I do not see the angular package here.

Is there an article or recommendations for angular 2 packages?
