Explanation:

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

Ethernet ensures that signals on a shared network never interfere with each other and become unreadable through the use of encapsulation and standard encryption protocols.

In Computer Networking, encapsulation can be defined as the process of adding a header to a data unit received by a lower layer protocol from a higher layer protocol during data transmission. This ultimately implies that, the header (segment) of a higher layer protocol such as an application layer, is the data of a lower layer such as a transportation layer in the Transmission Control Protocol and Internet Protocol (TCP/IP).

The TCP/IP model comprises of four (4) layers;

1. Application layer: this is the fourth layer of the TCP/IP model. Here, the data unit is encapsulated into segments and sent to the transport layer.

2. Transport layer (layer 3): it receives the segment and encapsulates it into packets and sends to the internet layer.

3. Internet layer (layer 2): packets are encapsulated into frames.

4. Network layer (layer 1): frames are then converted into bits and sent across the network (LAN).

Hence, the data unit encapsulated inside a packet is known as segment, which is typically referred to as packet segmentation.

Additionally, these data, segments, packets, frames and bits transmitted across various layers are known as protocol data units (PDUs).

Which of the following should get a Page Quality (PQ) rating of Low or Lowest? Select all that apply. True False A page with a m

Vikki [24]

The statement “All queries have only one intent: Know, Do, Website or Visit-in-Person intent” is True.

The statement “The intent of a Do query is to accomplish a goal or engage in an activity on a phone” is True.

The statement “The intent of a Website query is to find information” is True.

The statement “There is absolutely no information about who is responsible for the content of the website on a YMYL topic” is True.

The statement “All the Main Content(MC) of the page is copied and created with deceptive intent” is True.

The statement “A page with a mismatch between the location of the page and the rating location; for example, an English page for an English rating task’ is True.

“A file type other than a web page, for example; a PDF, a Microsoft Word document or a PNG file” is False.

Explanation:

The searcher tries to find out the Know queries. The action is taken by the searcher using the Do queries. The searcher looks for a site/ page using Website queries. The queries which are the same as they appear to be are Visit-in-Person queries.

The statement is true because in Do queries, the action is taken like the control of the smartphone is given to Google.

The search for a page or a site takes place using Website queries.

It is not always true that the Wikipedia pages should get high ratings for all user intents because information is helpful.

There is no surety that who will update the content of the website on a YMTL topic.

The Main Content (MC) of the low quality YMYL page helps the page to achieve its purpose. For YMYL the content is created with deceptive intent. The pages manipulate users to take action which will not help the users .

The PQ rating is lowest when there is a mismatch between the location of the page and the rating location, for example, an English rating task. Here, the purpose of the page is required to be understood to determine the rating.

The PQ rating is not determined by the type of the page but by the purpose of the page.
