Answer:
The correct options are;
-Position the keyboard directly in front and close to you so you don't have an excessive reach
-Keep your shoulders, arms, hands and fingers relaxed
-Position your wrists straight or in neutral position while typing
-Adjust your chair height and position so your feet rest flat on the floor, or add a footrest to compensate for a higher chair
-Adjust the keyboard height so that your shoulders can relax and your arms are straight in front of you
Explanation:
1) It is important to keep the fingers in a relaxed position when typing
2) Ensure to type in a tapping fashion when typing rather than pressing on the keys of the keyboard
3) The fingernails should be kept short when frequent typing is done
4) The wrist is better kept above the keyboard than resting on it
5) Ensure that the mouse is easily reached.
Answer:
All flags are On ( c, z , N )
Explanation:
Given data:
4-bit operation
Assuming 2's complement representation
<u>Determine status flags that are on after performing </u> 1010+0110
1 1
1 0 1 0
0 1 1 0
1 0 0 0 0
we will carry bit = 1 over
hence C = 1
given that: carry in = carry out there will be zero ( 0 ) overflow
hence V = 0
also Z = 1
But the most significant bit is N = 1
Answer:
import java.util.Scanner;
public class num8 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter month's budget");
double monthBudget = in.nextDouble();
double totalExpenses = 0.0;
double n;
do{
System.out.println("Enter expenses Enter zero to stop");
n = in.nextDouble();
totalExpenses += n;
}while(n>0);
System.out.println("Total expenses is "+totalExpenses);
System.out.println("The amount over your budget is "+ Math.abs(monthBudget-totalExpenses));
}
}
Explanation:
- Using Java programming language
- Prompt user for month's budget
- Use Scanner class to receive and store the amount entered in a variable
- Use a do while loop to continuously request user to enter amount of expenses
- Use a variable totalExpenses to add up all the expenses inside the do while loop
- Terminate the loop when user enters 0 as amount.
- Subtract totalExpenses from monthBudget and display the difference as the amount over the budget
Answer:
1. A browser is used to access websites and web pages whereas a search engine is used to search for particular information.
2. Indexing is the process by which search engines organise information before a search to enable super-fast responses to queries.
3.Search engines are used to find specialized data rapidly whereas web directory is used to find a list of different sites.
4. The working behind the PageRank algorithm is that a page with a large number of in- links(a link from an important page) to it, then its outgoing links to other pages also become important. It gives more importance to back links of a web page and propagates the ranking through links.
5. Look for Sites from Established Institutions 2. Look for Sites with Expertise 3. Steer Clear of Commercial Sites 4. Beware of Bias 5. Check the Date 6. Consider the Site's Look 7. Avoid Anonymous Authors 8. Check the Links
