Which of the following is a benefit, as well as a risk, associated with client/server networks?

List at least six things you would check for if you were asked to evaluate the workspace of an employee for ergonomics

Evgen [1.6K]

Assessing the risk that surrounds stationary work of employees spending hours at their stations is essential. Below is a list of fundamental ergonomic principles that help identify ergonomic risk factors.

1. Are the employees maintained in a neutral posture?

2. Does the stationery allow for movement and stretching?

3. Is there adequate lighting?

4. Are chairs adequately adjustable?

5. Are there appropriate foot rest?

6. Is there extra storage for better desk organization?

1- Design a brute-force algorithm for solving the problem below (provide pseudocode): You have a large container with storage si

sladkih [1.3K]

Answer:

Pseudocode is as follows:

// below is a function that takes two parameters:1. An array of items 2. An integer for weight W

// it returns an array of selected items which satisfy the given condition of sum <= max sum.

function findSubset( array items[], integer W)

{

initialize:

maxSum = 0;

ansArray = [];

// take each "item" from array to create all possible combinations of arrays by comparing with "W" and // "maxSum"

start the loop:

// include item in the ansArray[]

ansArray.push(item);

// remove the item from the items[]

items.pop(item);

ansArray.push(item1);

start the while loop(sum(ansArray[]) <= W):

// exclude the element already included and start including till

if (sum(ansArray[]) > maxSum)

// if true then include item in ansArray[]

ansArray.push(item);

// update the maxSum

maxSum = sum(ansArray[items]);

else

// move to next element

continue;

end the loop;

// again make the item[] same by pushing the popped element

items.push(item);

end the loop;

return the ansArray[]

}

Explanation:

You can find example to implement the algorithm.

Consider the following relation:CAR_SALE(Car#, Date_sold, Salesperson#, Commission%, Discount_amt)Assume that a car may be sold

GalinKa [24]

Answer:

The answer to this question can be given as:

Normalization:

Normalization usually includes the division of a table into two or more tables as well as defining a relation between the table. It is also used to check the quality of the database design. In the normalization, we use three-level that are 1NF, 2NF, 3NF.

First Normal Form (1NF):

In the 1NF each table contains unique data. for example employee id.

Second Normal Form (2NF):

In the 2NF form, every field in a table that is not a determiner of another field's contents must itself be a component of the table's other fields.

Third Normal Form (3NF):

In the 3NF form, no duplication of information is allowed.

Explanation:

The explanation of the question can be given as:

Since all attribute values are single atomic, the given relation CAR_SALE is in 1NF.
Salesperson# → commission% …Given Thus, it is not completely dependent on the primary key {Car#, Salesperson#}. Hence, it is not in 2 NF.

The 2 NF decomposition:

CAR_SALE_1(Car#, Salesperson#, Date_sold, Discount_amt)

CAR_SALE_2(Salesperson#, Commission%)

The relationship in question is not in 3NF because the nature of a transitive dependence occurs
Discount_amt → Date_sold → (Car#, Salesperson#) . Thus, Date_sold is neither the key itself nor the Discount amt sub-set is a prime attribute.

The 3 NF decomposition :

CAR_SALES_1A(Car#, Salesperson#, Date_sold)

CAR_SALES_1B(Date_sold, Discount_amt)

CAR_SALE_3(Salesperson#, Commission%)

Program documentation _____. Group of answer choices describes the inputs, outputs, and processing logic for all program modules

valentinak56 [21]

Answer:

In the given question the first line is correct, i.e. "Describes the inputs, outputs, and processing logic for all program modules".

Explanation:

The documentation is a recorded text or image, which is preceding or in the code base of the programs, whether it describes how well the program works and how it is being used, and things in various positions can be influenced by people, and the wrong option can be described as follows:

In the documentation, it can't consist of rules and data.
In can't include a dictionary, flow maps, screen designs and device requests that began the program.
In can't provide links within the program.
