Answer: Local Area Network (LAN)
Explanation:
A Local Area Network (LAN) is a computer network that interconnects computers within a limited physical area such as a residence, school, laboratory, university campus or office building.
An example of LAN network is "Phone, Computer and TV connected to a single network (such as a Home Network) via Cables, Wifi, Bluetooth or Hotspot". When the devices are interconnected or connected to a LAN, it becomes accessible between each other.
A simplest example of a LAN Device is a <em>Home Router.</em>
I guess the correct answer is concurrency control
Cοncurrеncy cοntrοl is a databasе managеmеnt systеms (DBMS) cοncеpt that is usеd tο addrеss cοnflicts with thе simultanеοus accеssing οr altеring οf data that can οccur with a multi-usеr systеm.
In database systems, the DBMS enforces rules about which user can perform which action when. The rules are known as concurrency control.
Answer:
Connection-oriented is the method which is implemented in the transport and data link layer. It is basically depend upon the physical connection in the network system.
Transmission control protocol (TCP) is the connection oriented and user datagram protocol (UDP) is the connection less network transport layer. The TCP and UDP both are operate in the internet protocol (IP).
It basically require connection and it can be establish before sending data. This is also known as reliable network connection service. The connection oriented service establish connection between the different connection terminal before sending any data or information. It can easily handle traffic efficiently.
Answer:
We can protect the server from the modification by using the non root users in many ways as follows:
- By modifying the PHP settings in the server and by using the configured file as, the configuration of the file is basically depend upon the linux and the PHP script.
- By disabling the URL from the function of file handling that basically accept the local file as the parameters but it also accept the URL. It can even now get to outer destinations by utilizing fsockopen or any of the CURL capacities.
- The safe mode of PHP is presumably probably the best alternative to secure your server however it very well may be prohibitive. Whenever initiated, experimental mode averts access to records not claimed by Apache and access to condition factors and execution of double projects are likewise debilitated.
Answer:
The code solution is written in Java.
- import java.util.Scanner;
-
- public class TestScore {
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
-
- System.out.print("Please enter first score: ");
- double firstScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(firstScore));
-
- System.out.print("Please enter second score: ");
- double secondScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(secondScore));
-
- System.out.print("Please enter third score: ");
- double thirdScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(thirdScore));
-
- System.out.print("Please enter fourth score: ");
- double fourthScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(fourthScore));
-
- System.out.print("Please enter fifth score: ");
- double fifthScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(fifthScore));
-
- System.out.println("Average score: " + calcAverage(firstScore, secondScore, thirdScore, fourthScore, fifthScore));
-
- }
-
- public static double calcAverage(double score1, double score2, double score3, double score4, double score5){
- double average = (score1 + score2 + score3 + score4 + score5) / 5;
- return average;
- }
-
- public static String determineGrade(double score){
- if(score >= 90){
- return "A";
- }
- else if(score >= 80 ){
- return "B";
- }
- else if(score >=70){
- return "C";
- }
- else if(score >=60){
- return "D";
- }
- else{
- return "F";
- }
- }
- }
Explanation:
Firstly, create the method, <em>calcAverage()</em>, that takes five test scores. Within the method, calculate the average and return it as output. (Line 33 - 36)
Next, create another method, <em>determineGrade()</em>, which takes only one score and return the grade based on the range of the score. (Line 38 -54)
Once the two required methods are created, we are ready to prompt use for input five test scores using Java Scanner class. To use get user input, create a Scanner object (Line 7). Next, use getDouble() method to get an input score and assign it to variables firstScore, secondScore, thirdScore, fourthScore & fifthScore, respectively. Once a score input by user, call determineGrade() method by passing the input score as argument and immediately print out the return grade. (Line 9 - 27)
At last, call calcAverage() method by passing the first test score variables as argument and print out the returned average value. (Line 29).
