Print preview allows you to view the layout of your paper before you print it hence the pre part of preview.

A feature called print preview shows what a printed copy would look like on the screen. By checking the layout using print preview before printing, you can detect any potential problems and prevent the need for multiple prints, saving ink or toner and paper.

You can examine a page in landscape mode by switching the page orientation in the print preview from portrait to landscape. Sadly, not all software supports this function.

You are unable to see how your page will print in landscape format if the program you are using lacks any settings or print preview features.

Therefore, Print preview allows you to view the layout of your paper before you print it hence the pre part of preview.

Answer:

The correct option is B. Set all Organization-Wide Default security to be "Private" for both internal and external users and use Sharing Rules to grant the desired access.

Explanation:

Note: This question is not complete as the options are not included. The complete question with the options is therefore provided before answering the question as follows:

Universal Containers is designing a new community using the Customer Community license type. They would like to have the users complete survey questions through the community interface and store the responses in a Custom Object that has a lookup to the account object. Any internal user who has access to the account should be able to see all survey responses. All Customer Community users should be able to see surveys filled in by other users for their company, but not surveys for other companies. What are the correct security settings to achieve this?

A. Set all Organization-Wide Default security to be "Public Read/Write" for internal users and "Private" for external users.

B. Set all Organization-Wide Default security to be "Private" for both internal and external users and use Sharing Rules to grant the desired access

C. Set all Organization-Wide Default settings to be "Public Read/Write" for both internal and external users.

D. Set the custom object to be master-detail to the Account and leave the Organization-Wide Default settings as their default values.

The explanation of the answer is now provided as follows:

Organization Wide Default security refers to settings that provides most restrictive settings that may be opened up by Role Hierarchy and Role hierarchy can be opened by Sharing rules. And the visibility of records at the record level is determined by all of these factors. Private, Public Read, Read/Write, and Read/Write & Transfer are the four permissions available in Sharing Rules.

The rules that are used to offer sharing access to users in public groups, roles, or territories are referred to as sharing rules. By introducing automatic exceptions to your org-wide sharing policies, sharing rules allow certain users more access.

By implication, the correct security settings to achieve the objective stated in the question is to set all Organization-Wide Default security to be "Private" for both internal and external users and use Sharing Rules to grant the desired access.

Therefore, the correct option is B. Set all Organization-Wide Default security to be "Private" for both internal and external users and use Sharing Rules to grant the desired access.

Answer:

standardization

Explanation:

A problem can be defined as an issue or challenge encountered by a person, which typically requires a solution.

Generally, problems are considered to be either simple or complex depending on the individual, parameters, and factors involved.

This ultimately implies that, problems are relative in nature but always require that a solution be proffered.

In this scenario, a broken monitor on a desktop system needs to be replaced. You then decided to replace the monitor with a spare monitor that wasn't being used.

Although, the spare (replacement) monitor was manufactured by a different manufacturer than the desktop computer but it still worked with the computer. Thus, the computer design concept which makes this possible is referred to as standardization.

Standardization can be defined as a design concept which avails users the opportunity to use various components from different manufacturers interchangeably without any defect or compromise of the integrity of a system. The most important criteria to be considered is if the components meet set standards i.e specifications of the system.

[tex]= I \times 0.01 \times 10 = 0.1 I[/tex]

Data miss cycles[tex]= I \times 0.05 \times 10 \times 0.40 = 0.2 I[/tex]  

The Secondary to main Memory Instruction miss cycle[tex]= I \times 0.01 \times 200 \times 0.0002 = 0.004 I[/tex]

Data miss cycles[tex]= I \times 0.05 \times 200 \times 0.0002 = 0.002 I[/tex]

Total memory stall cycle [tex]= ( 0.1 + 0.2 + 0.004 + 0.002 ) I =0.306 I[/tex]
