You have just taken over management of a server on which the previous server administrator has set up several server components,

including the hard drives to be hot swappable. However, you notice that server performance is slow and disk reading and writing sometimes is delayed. What step can you take to improve the performance of the disk drives?a. Check the disk controllers for a switch you can set for faster disk rotation.b. Use the Control Panel Disk applet to double the disk transfer speedc. Allocate more RAM for disk transfersd. Ensure file caching and flushing are enabled for all disk drives

Answer:

d. Ensure file caching and flushing are enabled for all disk drives.

Explanation:

When the disk reading and writing is delayed and the server performance is also slow after taking over management of a server.Previously the server has several server components.So to increase the performance we should ensure caching of the file and make sure that the flushing is enabled for all disk drives.Hence the answer to this question is option d.

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.

Which of the following is not a valid SQL command? (Points : 2) UPDATE acctmanager SET amedate = SYSDATE WHERE amid = 'J500';
Volgvan

Answer:

UPDATE acctmanager WHERE amid = 'J500';

Explanation:

The statement written above is not valid SQL statement because there is no SET after UPDATE. Update is always used with SET.If you are updating something then you need to specify the value with which that value should be replaced.

UPDATE acctmanager SET amname = UPPER(amname);

This statement does not contains WHERE clause but it will run all the values of amname column will get updated in the table acctmanager.
