Question

1. which url is considered a complete address?

www.business - skills.weebly.com
microsoft.com/en - us/download/details.aspx?id = 18302

1. what is a domain name?

the www. part of a web address
a set of numbers that represent an address
a user - friendly, alphabetic web address/name
the http:/ part of a web address

Explanation:

For question 15: A complete URL should have a protocol (like http:// or https://), domain name, and path (if applicable). The first option is missing the protocol. The second option, although it may seem like it's missing the protocol (in a real - world context, browsers assume http/https), but in terms of a more complete structure (if we consider the general form), it has a domain (microsoft.com) and a path (/en - us/download/details.aspx?id = 18302).
For question 16: A domain name is a user - friendly, alphabetic web address/name. The "www." is just a sub - domain prefix. A set of numbers representing an address is an IP address. The "http:/" is the protocol part of a web address.

Answer:

1. microsoft.com/en - us/download/details.aspx?id = 18302
2. a user - friendly, alphabetic web address/name
