Answer 1

Answer:

D. Web Server

Explanation:

When you type cengage.com in your browser, the browser takes this request and sends it to a server via a HTTP(Hypertext Transfer Protocol) server.The web server is responsible for responding to this request with the appropriate response. Every response received from the Webe server has a response code.  Here are some of the responses that you can get:

1. 200 (ok): this means that the request was processed successfully and the appropriate webpage or resource is returned.
2. 400(bad request) this means that the web server could not understand the request that was sent, because of a bad/syntax error.
3. 401(unauthorized request) : this means that the person/client sending this request does not have the appropriate permission to get access the resource. Authentication is needed.
4. 404(not found): this means that the resource or webpage being requested for cannot be found.

These are few among several other response codes that exist.

In the case of this question, the Page not found error(also known as 404 error) is received because the website page(cengage.com) being requested for by the browser was not found on the web server.
