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.

I am having trouble figuring out if this is correct. Can someone please help me ASAP?
CaHeK987 [17]

Explanation:

The X's have been correctly placed in the chart

A surge suppressor, which is also commonly known as a surge protector, is an important equipment that helps prevent damage to electric components from an unexpected increase of voltage. Let’s assume that you are living in a county where the effective utility voltage is between 110 to 120 volts. Assume that the accepted peak voltage should not be anything higher than 170 volts. If there is a surge and this surge reaches peak levels of 170 volts and higher, surge suppressors should jump in and prevent the peak AC voltage from going above the threshold.

People tend to confuse line conditioners and surge suppressors. While surge suppressors protect components from surges, line conditioners are built to make up for the loss of voltage from the lines. It does so by storing some power energy. This stored energy can later be modified and used when the volts drops to the desired 110 volts.

A UPS has DC battery power that provides battery backup power when the electricity goes off or when the levels of voltage drop significantly. When the electricity goes off means that the voltage is at 0 volts and it is the work of the UPS to kick its backup power in.

Crazy boy [7]

A(n) client exists a computer that requests and utilizes network resources from a(n) server.

<h3>What is a computer network?</h3>
  • A computer network is a collection of computers that share resources that are available on or provided by network nodes.
  • The computers communicate with one another via digital links using standard communication protocols.
  • These links are made up of telecommunication network technologies that are based on physically wired, optical, and wireless radio-frequency means and can be configured in a variety of network topologies.
  • Nodes in a computer network can be personal computers, servers, networking equipment, or other specialized or general-purpose hosts.
  • They can be identified by network addresses and have hostnames.
  • Local-area networks (LANs) and wide-area networks (WANs) are the two basic network types.
  • A(n) client exists a computer that requests and utilizes network resources from a(n) server.
