1. Create a detail report that will display all SCR courses in alphabetical order, with the course name and the instructor name

in a group header; the Social Security number, name, and telephone number of each current student in the detail section; and the student count in group footer. 2. Create a switchboard design with control buttons that lead to students, instructors, courses, course schedules, and course rosters. Allow a user to add, update, or delete records in each area. Jesse wants to see storyboards that show the proposed screens. 3. Suggest data validation checks for data entry screens. 4. Create a source document for an SCR mail-in registration form. Also need a design for a Web-based course registration form.

Answer:The interface is the means by which a user communicates with a system, whether to get it to perform some function or computation directly (e.g., compute a trajectory, change a word in a text file, display a video); to find and deliver information (e.g., getting a paper from the Web or information from a database); or to provide ways of interacting with other people (e.g., participate in a chat group, send e-mail, jointly edit a document). As a communications vehicle, interfaces can be assessed and compared in terms of three key dimensions: (1) the language(s) they use, (2) the ways in which they allow users to say things in the language(s), and (3) the surface(s) or device(s) used to produce output (or register input) expressions of the language. The design and implementation of an interface entail choosing (or designing) the language for communication, specifying the ways in which users may express ''statements" of that language (e.g., by typing words or by pointing at icons), and selecting device(s) that allow communication to be realized-the input/output devices.

Box 3.1 gives some examples of choices at each of these levels. Although the selection and integration of input/output devices will generally involve hardware concerns (e.g., choices among keyboard, mouse, drawing surfaces, sensor-equipped apparel), decisions about the language definition and means of expression affect interpretation processes that are largely treated in software. The rest of this section briefly describes each of the dimensions and then examines how they can be used

1. What are the advantages and disadvantages of technology in communication?
Gennadij [26K]

Answer:

ADVANTAGES:

First, the evolution of technology is beneficial to humans for several reasons. At the medical level, technology can help treat more sick people and consequently save many lives and combat very harmful viruses and bacteria.

2-Technology has also increased the productivity of almost every industry in the world. Thanks to technology, we can even pay with bitcoins instead of using banks

DISADVANTAGES:

1-Lack of Privacy. You might think that a quick text or IM offers more privacy than a telephone call in a crowded room. ...

2-Distraction from Real Life. ...

3-Potential for Misunderstanding. ...

4-Decline of Grammar and Spelling...

5- Near people are far and far people are near through communication technology. we have no time to sit with our relatives but constantly communicate far away people . I think this is biggest <em>disadvantage </em>

Using Matlab programming I need to rotate the line defined by x,y by 45 degrees around 2,2
belka [17]

Answer:

% here x and y is given which we can take as

x = 2:2:10;

y = 2:2:10;

% creating a matrix of the points

point_matrix = [x;y];

%  center point of rotation  which is 2,2 here

x_center_pt = x(2);

y_center_pt = y(2);

% creating a matrix of the center point

center_matrix = repmat([x_center_pt; y_center_pt], 1, length(x));

% rotation matrix with rotation degree which is 45 degree

rot_degree = pi/4;      

Rotate_matrix = [cos(rot_degree) -sin(rot_degree); sin(rot_degree) cos(rot_degree)];

% shifting points  for the center of rotation to be at the origin

new_matrix = point_matrix - center_matrix;  

% appling rotation  

new_matrix1 = Rotate_matrix*new_matrix;          

Explanation:

We start the program by taking vector of the point given to us and create a matrix by adding a scaler to each units with repmat at te center point which is (2,2). Then we find the rotation matrix by taking the roatational degree which is 45 given to us. After that we shift the points to the origin and then apply rotation ans store it in a new matrix called new_matrix1.

In mathematics, the notation n! represents the factorial of the nonnegative integer n. The factorial of n is the product of all
hram777 [196]

Answer:

The program to this question can be given as:

Program:

factorial=1 #declare a variable.  

number=int(input("Enter a positive integer:")) #input a number.  

while (number>0): #loop  

   factorial= factorial*number # holding value in factorial variable  

   number=number-1  

print('=',factorial) #print value.

Output:

Enter a positive integer:6  

= 720  

Explanation:

The description of the above python program can be given as:

  • In the above program firstly we define a variable that is "factorial". In this variable, we assign a value that is 1 and it is used to calculate the factorial value.  
  • We define a variable "number". The number variable is used to take input from the user.  
  • Then we define a loop in the loop we calculate the factorial and hold the value in the factorial value in the last we print the value.
