Consider a file system with a graphical user interface, such as Macintosh’s Finder, Microsoft’s Windows Explorer, or Linux’s KDE. The following objects were identified from a use case describing how to copy a file from a USB flash disk to a hard disk: File, Icon, TrashCan, Folder, Disk, Pointer. Specify which are entity objects, which are boundary objects, and which are control objects?

Answers

Answer 1

If we have a graphical user interface (GUI) based file system and objects were identified from a use case describing how to copy a file from a USB flash disk to a hard disk, then the entity objects are file, folder and disk, the boundary objects are icon, trash can and pointer and none of the objects given are control objects.

Entity objects are the system components that represent a particular domain concept in the application. These objects do not have knowledge of other parts of the system and only respond to specific queries from the control objects. The entity objects in this context are file, folder and disk.

Boundary objects in the system refer to the components that provide a bridge between the outside world and the application. They are responsible for collecting data from the user and passing it to the control objects for processing and also for retrieving processed data from the control objects and presenting it to the user. The boundary objects in this context are icon, trash can, and pointer.

Control objects are the application components that are responsible for processing data from the boundary objects and manipulating the entity objects. They implement the business logic of the application and decide what to do with the data provided by the boundary objects and how to manipulate the entity objects. So, none of the objects listed in the question is a control object as they do not have any ability to process data on their own.

an insurance agent is paid a salary of 200gh cedis and a commission of 3% on all sales over 2000gh cedis per month. if his total income in a particular month was 530gh cedis, what was the amount of his sales for that month? ​

Answers

Answer: 11000gh cedis

Explanation:

Since the salary of the insurance agent is 200gh cedis and his total income for the month was 530gh cedis, that means that the commission he got was:

= 530gh cedis - 200gh cedis

= 330gh cedis

Since he gets 3% on all sales and made 330gh as commission, the amount of sales for the month will be:

3% of x = 330

0.03 × x = 330

0.03x = 330

x = 330/0.03

x = 11000

Therefore, the sales was 11000gh cedis

find the id, first name, and last name of each customer that currently has an invoice on file for wild bird food (25 lb)

Answers

To provide the ID, first name, and last name of each customer who currently has an invoice on file for wild bird food (25 lb), the specific data from the database or system needs to be accessed. Without access to the specific data source, it is not possible to provide the direct answer.

To find the required information, you would typically need to query a database or system that stores customer and invoice data. The query would involve joining tables related to customers and invoices, filtering for invoices with the specified product (wild bird food, 25 lb). The specific database schema and structure would determine the tables and fields involved in the query.

Here's an example SQL query that demonstrates the concept, assuming a simplified database schema:

```sql

SELECT c.id, c.first_name, c.last_name

FROM customers c

JOIN invoices i ON c.id = i.customer_id

JOIN invoice_items ii ON i.id = ii.invoice_id

JOIN products p ON ii.product_id = p.id

WHERE p.name = 'wild bird food' AND p.weight = 25;

```

In this example, the query joins the `customers`, `invoices`, `invoice_items`, and `products` tables, filtering for the specified product name ('wild bird food') and weight (25 lb). The result would include the ID, first name, and last name of each customer who has an invoice on file for that particular product.

Please note that the actual query may vary depending on the specific database schema and structure, and the query language being used.

Without access to the specific data and database structure, it is not possible to provide the direct answer to the query. However, the explanation and example query provided should give you an understanding of the process involved in retrieving the required information from a database or system.

A CSIRT model that is effective for large organizations and for organizations with major computing resources at distant locations is the ____. a. central CSIRT
b. coordinating team
c. organizational CSIRT
d. distributed CSIRT

Answers

The distributed CSIRT model is the most suitable option for large organizations with major computing resources at distant locations. A distributed CSIRT (Computer Security Incident Response Team) model is effective for large organizations and organizations with major computing resources at distant locations.

In this model, the CSIRT is divided into multiple teams or sub-teams that are geographically distributed across different locations. Each team is responsible for handling security incidents within their respective area of coverage. The distributed CSIRT model allows for faster response times and efficient management of incidents across multiple locations. It also enables organizations to leverage the expertise and resources available at each location, ensuring that incidents can be effectively addressed regardless of their origin.

On the other hand, the other options mentioned are as follows:

a. A central CSIRT refers to a single centralized team responsible for handling security incidents across the entire organization. It may not be as effective for large organizations with widespread computing resources.

b. A coordinating team typically works in conjunction with other teams, including a CSIRT, to coordinate incident response efforts. While it plays a role in incident response, it is not specifically designed for large organizations with major computing resources.

c. An organizational CSIRT is a general term that encompasses any CSIRT within an organization, whether it's centralized or distributed. It does not specifically refer to a model designed for large organizations with major computing resources at distant locations.

How to build adjacency matrix for undirected/directed graph?

Answers

An adjacency matrix is a 2D array in which each row and column represent a vertex in the graph. The value stored in the matrix indicates whether the two vertices have an edge between them or not. The adjacency matrix for an undirected graph is symmetrical along the diagonal, whereas the adjacency matrix for a directed graph is not.

Both the rows and columns in an adjacency matrix for an undirected graph have the same number of entries. Additionally, when there is an edge from vertex i to vertex j in an undirected graph, the value at A[i,j] and A[j,i] is 1. It is symmetrical about the leading diagonal in this way. Furthermore .

An adjacency matrix for a directed graph, on the other hand, is not symmetrical around the main diagonal. The number of entries in the rows and columns may vary in an adjacency matrix for a directed graph, depending on the number of incoming and outgoing edges for each vertex. If there is an edge from vertex i to vertex j, the value in A[i,j] is 1, but the value in A[j,i] is 0 if there is no edge from j to i. An example of a directed graph's adjacency matrix is given below:

Unix-based systems with access control lists might raise problems such as limiting the system administrator's ability to manage security settings or fix potential issues, leading to increased complexity in managing user permissions.


In general, access control lists are an important security feature of Unix-based systems, as they allow administrators to manage access to resources on a granular level. By restricting root access to the ACL, system administrators can help ensure that changes to the system are made intentionally and with appropriate oversight. Additionally, by limiting the number of users who can modify the ACL, system administrators can help prevent accidental changes or unauthorized access to sensitive resources.

Explain how Steve Jobs created and introduced the iPhone and iPad.

Answers

Answer:Today, we're introducing three revolutionary products. The first one is a widescreen iPod with touch controls. The second is a revolutionary mobile phone. And the third is a breakthrough Internet communications device. So, three things: a widescreen iPod with touch controls, a revolutionary mobile phone, and a breakthrough Internet communications device. An iPod, a phone, and an Internet communicator. An iPod, a phone...are you getting it? These are not three separate devices. This is one device. And we are calling it iPhone. Today, Apple is going to reinvent the phone.

Late last year, former Apple engineer Andy Grignon, who was in charge of the radios on the original iPhone, gave behind-the-scenes look at how Apple patched together demos for the introduction, with Steve Jobs showing off developmental devices full of buggy software and hardware issues. The iPhone team knew that everything had to go just right for the live iPhone demos to succeed, and they did, turning the smartphone industry on its head even as Apple continue to scramble to finish work on the iPhone.

Apple had actually been interested first in developing a tablet known as "Safari Pad", but as noted by a number of sources including Steve Jobs himself, the company shifted gears once it became clear how revolutionary the multi-touch interface developed for the tablet could be for a smartphone. Apple's tablet wouldn't surface until the launch of the iPad in 2010, three years after the introduction of the iPhone.

Seven years after the famous Macworld 2007 keynote, the iPhone has seen significant enhancements in every area, but the original iPhone remains recognizable as Apple has maintained the overall look of a sleek design with a larger touchscreen and a single round home button on the face of the device.

how many 8-bit strings contain 5 or more 1’s?

Answers

There exist 37 8-bit strings contain  5or more 1s.

What are strings?The strings, which make up the majority of the orchestra, are composed of four sizes: the violin, which is the smallest, viola, cello, and double bass, also known as the contrabass. Text and character storage is done through strings. A string of characters is, for instance, "Hello World."In C programming, a string is a collection of characters that is terminated with the null character "0." An array of characters is how strings are defined. A string and a character array vary in that a string is finished with the distinctive letter "0." A string is a programming data type that represents words rather than integers.

We need to consider 3 different cases. In each case, the 8-bit string is entirely determined by the location of the \($1 \mathrm{~s}$\).

Case 1: there are six 1s. We need to find how many ways there are to arrange\($61 \mathrm{~s}$\)among 8 positions. This is \($C(8,6)$\).

Case 2: there are seven 1s. Following the same logic as in case 1 , there are \($C(8,7)$\)strings that contain seven 15.

Case 3: there are eight 1s. There's only one 8-bit string that has eight \($1 \mathrm{~s}$\) since \($C(8,8)=1$\).

Since there is no overlap between these three cases, the addition principle is used to determine the total number of 8 -bit strings that contain at least six \($1 \mathrm{~s}$\) :

\($$C(8,6)+C(8,7)+C(8,8)=28+8+1=37$$\)
