Answer:
1. get the absolute path to the file
2. load the file as a table (dataframe in python)
3. to insert a row;
create a dataframe of the same field typeconcatenate the new dataframe horizontally with the same dataframe4. to delete a row, select and drop the row where the 'Number' field matches a value.
5. to update the values in row, use the number field as a key to replace the existing values.
6. print of save to a variable the rows where the number field matches a given value.
Explanation:
Follow the report template to create a report for the algorithm.
The algorithm gets the absolute path to the file and loads the file as a tabular file from there the data can be queried without accessing the main file. The insert algorithm creates a new dataframe and appends it to the main dataframe.
The delete, update and retrieve all use the same subalgorithm, getting the rows with the number field as the key value.

You need to replace a broken monitor on a desktop system. You decide to replace it with a spare monitor that wasn't being used. Even though the monitor is made by a different manufacturer than the desktop computer, it still works with the computer. Which computer design concept makes this possible
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.

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
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.
