What is the difference between trusted ip and login ip range in Salesforce?

Trusted IP range: It defines a list of IP addresses from which users can log in without receiving a login challenge for verification of their identity, such as a code sent to their mobile phone.
Login IP range: You can control login access on a user’s profile by specifying a range of IP addresses. When you define IP address restrictions for a profile, any login from a restricted IP address is denied.
