It really depends on your type of data, if it's sensitive data or not. And it also depends on what type of backup (Incremental, Decremental, etc.). But you should aim to backup at least once a week, and also do a backup of your original backup.
Answer:
1. C) Embedded Style
2. C) User Agent Style
Explanation:
1. Alex will use Embedded style to create styles that apply only to the HTML document that the style was created. With Embedded styling; the rules can be embedded into the HTML document using the <style> element.
2. Since Alex has forgotten to give any style for all of his pages, the style that will be applied to his pages is User Agent Style. User Agent Style is the default style of a browser. The browser has a basic style sheet that gives a default style to any document and this style is called User Agent.
Answer:
Option d is the correct answer for the above question.
Explanation:
- The first loop of the program has a second loop and then the statement. In this scenario, the second loop executes for the value of the first loop and the statement executes for the value of the second loop.
- The first loop executes 4 times, Then the second loop or inner loop executes n times for the n iteration of the first loop, for example, 1 time for the first iteration of the first loop, 2 times for the second iteration of the first loop and so on.
- Then the inner loop executes (1+2+3+4) iteration which gives the result 10 iterations.
- The sum initial value is 0 and the "sum++", increase the value of the sum by 1.
- So the value of the sum becomes 10 after completing 10 iterations of the inner for loop.
- Hence the 10 will be the output. So the Option d is the correct answer while the other is not.
Answer:
Multiprogramming will be extremely difficult to be achieved.
Explanation:
If every byte of data read or written is handled by the CPU the implications this will have for multiprogramming are not going to be satisfactory.
This is because, unlike before, after the successful completion of the input and output process, the CPU of a computer is not entirely free to work on other instructions or processes.
