Answer:

Media queries

Explanation:

Today, websites have to take into account the increasing volume of users who navigate using smart devices, phones and tablets.

These devices generally have screen dimensions and resolutions much smaller than those offered by desktops and laptops for which many websites were initially designed.

Ideally, the design of the site should be adapted to these means, for which it needs to detect the characteristics of the device from which it is being accessed and adapt to it. Initially, the mechanism of the meta viewport tag was specified, which we have already studied in other articles. Currently, more precise control can be obtained using CSS media queries. With them, you can define sets of differentiated CSS rules for different screen resolutions, device orientations, etc., so that the design is adapted without generating a different HTML code for each type of device.

Media queries are used to associate a style sheet or style rule with a specific device or list of device features .This technique is used for delivering a tailored style sheet to different devices and applying CSS styles depending on a device's general type, specific characteristics or environment.

What set of code correctly initializes all elements of the array ar to the value 0, given the declaration

Veronika [31]

Answer:

The correct answer is:

C. ndx = 0;

while (ndx < 3) {

ar[ndx] = 0;

ndx++;

}

Explanation:

The declaration given is:

int ar[3];

This means the array consists of three locations and is named as ar.

We know that the indexes are used to address the locations of an array and the index starts from 0 and goes upto to 1 less than the size of the array which means the indexes of array of 3 elements will start from 0 and end at 2.

Now in the given options we are using ndx variable to run the while loop.

So the code to assign zero to all elements of array will be

ndx = 0;

while(ndx<3)

{

ar[ndx] = 0;

ndx++;

}

Hence, the correct answer is:

C. ndx = 0;

while (ndx < 3) {

ar[ndx] = 0;

ndx++;

}

Use semaphore(s) to solve the following problem. There are three processes: P1, P2, and P3. Each process Pi has a segment of cod

Lisa [10]

Answer:

See explaination

Explanation:

Here we will use two semaphore variables to satisfy our goal

We will initialize s1=1 and s2=1 globally and they are accessed by all 3 processes and use up and down operations in following way

Code:-

s1,s2=1

P1 P2 P3

P(s1)

P(s2)

V(s2) .

P(s2). .

. C2

V(s1) .

P(s1)

. . C3

V(s2)

Explanation:-

The P(s1) stands for down operation for semaphore s1 and V(s1) stands for Up operation for semaphore s1.

The Down operation on s1=1 will make it s1=0 and our process will execute ,and down on s1=0 will block the process

The Up operation on s1=0 will unblock the process and on s1=1 will be normal execution of process

Now in the above code:

1)If C1 is executed first then it means down on s1,s2 will make it zero and up on s2 will make it 1, so in that case C3 cannot execute because P3 has down operation on s1 before C3 ,so C2 will execute by performing down on s2 and after that Up on s1 will be done by P2 and then C3 can execute

So our first condition gets satisfied

2)If C1 is not executed earlier means:-

a)If C2 is executed by performing down on S2 then s2=0,so definitely C3 will be executed because down(s2) in case of C1 will block the process P1 and after C3 execute Up operation on s2 ,C1 can execute because P1 gets unblocked .

b)If C3 is executed by performing down on s1 then s1=0 ,so definitely C2 will be executed now ,because down on s1 will block the process P1 and after that P2 will perform up on s1 ,so P1 gets unblocked

So C1 will be executed after C2 and C3 ,hence our 2nd condition satisfied.

Time-management techniques work most effectively when performed in which order?

Sholpan [36]

Answer:

study-time survey, project schedule, prioritize tasks, reward system.

Explanation:

Time management can be defined as a strategic process which typically involves organizing, planning and controlling the time spent on an activity, so as to effectively and efficiently enhance productivity. Thus, when time is properly managed, it avails us the opportunity to work smartly rather than tediously (hardly) and as such making it possible to achieve quite a lot within a short timeframe. Also, a good time management helps us to deal with work-related pressures and tight schedules through the process of properly allocating the right time to the right activity.

Hence, time-management techniques work most effectively when performed in the following sequential order; study-time survey, project schedule, prioritize tasks, and designing (creating) a reward system.
