What is the range of the well-known ports used by tcp and udp?

1 answer:

8 0

/etc/services on my CentOS machine goes up to 49000. Reserved ports are less than 1024.

Well known and reserved ports are two different things. Well known ports only need a registration with IANA. Reserved ports, on *nixes, requires root for a deamon to bind to the port.

Construct a SQL query that displays a list of colleges, their sity/state, the accrediting agency, and whether or not the school

Alex787 [66]

Answer:

SELECT college, city_state, accre_agency, distance LIMIT 10

Explanation:

Given

Table name: College

See attachment for table

Required

Retrieve top 10 college, state, agency and school distance from the table

To retrieve from a table, we make use of the SELECT query

The select statement is then followed by the columns to be selected (separated by comma (,))

So, we have:

SELECT college, city_state, accre_agency, distance

From the question, we are to select only first 10 records.

This is achieved using the LIMIT clause

i.e. LIMIT 10 for first 10

So, the complete query is:

SELECT college, city_state, accre_agency, distance LIMIT 10

Iven an array temps of double s, containing temperature data, compute the average temperature. Store the average in a variable c

ale4655 [162]

Answer:

import java.util.Arrays;

import java.util.Scanner;

public class num1 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter length of the array:");

int len = in.nextInt();

double [] temps = new double[len];

double avgTem;

int k =0;

double total = 0;

for( k=0; k<temps.length; k++){

System.out.println("Enter values for the array");

temps[k]=in.nextDouble();

}

System.out.println("The Arrays contains the following values");

System.out.println(Arrays.toString(temps));

// Computing the average of the values

for(k=0; k<temps.length; k++){

total = total+temps[k];

}

avgTem = total/(temps.length);

System.out.println("The average Temperature is: "+avgTem);

}

Explanation:

Using Java programming language
Import the Scanner class to receive user input
Prompt User for the length of the Array, receive and store in a variable len;
Declare a new double array of size len double [] temps = new double[len];
Using a for loop, continually prompt user to enter values into the array
Display the values of the array using Java's Arrays.toString method
Use another for loop to add up all the elements in the arraay and store in the variable called total
Outside the second for loop calculate the average avgTem = total/(temps.length);
Display the average temp.

EleoNora [17]

Answer:

C Programming language.

Explanation:

A scripting language is a type of programming language, so D cannot be correct.
A markup language is a way to edit documents, so A cannot be correct.
An indexed language refers to linguistics and is thus irrelevant.
