If you have enabled Customer Registration and have not checked the option to require registration to checkout then the shopping cart will display links for the shopper to Sign in or Register but they will not be required to in order to checkout. They will be able to click the checkout button and continue without registering.
If you check the box to require registration in order to place an order the shopping cart will still have the same look but they will not be able to checkout without registering or signing in.
Commerce Setup > Customer Registration is where you configure the registration options.
