Answer: A) Your user inadvertently downloaded a macro virus using IM

Explanation:

As the user has downloaded a file from a prospective client ad the file was account.doc, but since then the system of the user has not been behaving normally so the most possible reason could have been the user has inadvertently downloaded a micro virus using the IM. These micro virus are invisible programs which can be transferred inadvertently from one user to another another. They can be transported over the network.

Option b is not correct as the user has not download a rootkit as it would require special privileges.

Option c is not correct as the user upon changing a setting in the system can reset it.

Option d is not correct as using the IM is not unstable to the system.

So, the correct option is A.

A biologic reaction is produced by 4 Gyt of a test radiation. It takes 16 Gyt of 250-kVp x-rays to produce the same biologic rea
Shalnov [3]

Answer:

4

Explanation:

Relative Biological Effectiveness (RBE) =

Standard Radiation dose / Test Radiation dose

for achieving the same biological effect.

The absorbed radiation dose is measured in units of Gyt(Gray in tissue).

In the given scenario, Standard radiation dose of 250 KVp X-rays = 16 Gyt

Corresponding Test Radiation dose = 4 Gyt

Therefore, Relative Biological Effectiveness = 16/4 = 4

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.

Purpose computer been found is to do huge calculation. “Compute” word has been derived to computer. Computer later stage it diverted is purpose from calculation to information store device.

Computers have heavy effect the communication in normal word and business world. Especially social media took over the control of computers. In today’s world four type of ethical issue are known in computer mainstream in the workplace they are.
