Why OSI is called open system?

1 answer:

7 0

Answer: OSI system is called Open System Interconnection because It provides the collection of protocols for the connection of different system to connect with any dependence on any other system or network.

Explanation: Open system interconnection establishes a connection between the different system for the communication purpose using several protocols and software standards .It has no dependency or any network or other system to do the functioning and works using the seven layers of the OSI architecture.Thus, that is why OSI system known as open system.

Create a program that allows the user to pick and enter a low and a high number. Your program should generate 10 random numbers

Natalka [10]

Answer:

import java.util.Scanner;

import java.util.Arrays;

import java.util.Random;

public class Main {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.print("Enter low: ");

int low = scan.nextInt();

System.out.print("Enter high: ");

int high = scan.nextInt();

scan.close();

int rndnumbers[] = new int[10];

Random r = new Random();

for(int i=0; i<rndnumbers.length; i++) {

rndnumbers[i] = r.nextInt(high-low+1) + low;

}

for(int i=0; i<rndnumbers.length; i++) {

System.out.printf("%d: %d\n", i, rndnumbers[i]);

Code a call to the function anotherFunc passing the array myints.

mario62 [17]

Answer:

d)anotherFunc(myints);

Explanation:

When we call a function we just have to pass the names of the arguments to the function.In case of arrays we also just have to pass the name of the array.We don't have to worry about the square brackets.So the function call will be like this.

anotherFunc(myints);

Hence the answer is option d.

Write a program that reads in a temperature value in °F. Create a function ConvertFahrenheit that takes that value as a paramete

larisa86 [58]

Answer:

#include<stdio.h>

void ConvertFahrenheit(float);

void main()

{

float fahrenheit_temp;

printf("Input the temperature in Fahrenheit: ");

scanf("%f", &fahrenheit_temp);

ConvertFahrenheit(fahrenheit_temp);

}

void ConvertFahrenheit(float fahren) {

float c, k;

c = (fahren - 32)/1.8;

k = (fahren + 459.67)/1.8;

printf("Celsius = %f\n", c);

printf("Kelvin = %f", k);

}

Explanation:

Inside the main function, take the temperature in Fahrenheit as an input from user and call the ConvertFahrenheit function by passing it the fahrenheit_temp variable as an argument.
Create the ConvertFahrenheit function for the conversion and convert the fahrenheit value to the Celsius and Kelvin by using their conversion formulas respectively.
Lastly, display the result in Celsius and Kelvin.

Research 3 distributions that utilize the big data file systems approaches, and summarize the characteristics and provided funct

OlgaM077 [116]

Answer:

Explanation:

1: The three most popular data systems that make use of Big Data file systems approach are:

The HDFS (Hadoop Distributed File System), Apache Spark, and Quantcast File System(QFS).

HDFS is the most popular among these and it makes use of the MapReduce algorithm to perform the data management tasks. It can highly tolerate faults and can run on low-cost hardware. It was written in Java and it is an open-source software.

Apache Spark makes use of Resilient Distributed Data (RDD) protocol. It is much faster and lighter than the HDFS and it can be programmed using a variety of languages such as Java, Scala, Python, etc. Its main advantage over HDFS is that it is highly scalable.

While QFS was developed as an alternative to the HDFS and it is also highly fault-tolerant and with space efficient. It makes use of the Reed-Solomon Error Correction technique to perform the task of data management.

2: The NewSQL databases were developed as a solution to the scalability challenges of the monolithic SQL databases. They were designed to allow multiple nodes in the context of an SQL database without affecting the replication architecture. It worked really well during the starting years of the cloud technology. Some of the databases that make use of New SQL technology are Vitess, Citus, etc.

Vitess was developed as an automatic sharding solution to the MySQL. Every MySQL instance acts as a shard of the overall database and each of these instances uses standard MySQL master-slave replication to ensure higher availability.

While, Citus is a PostgreSQL equivalent of the Vitess. It ensures transparent sharding due to which it accounts for horizontal write scalability to PostgreSQL deployments.

NoSQL database technology was developed to provide a mechanism for the storage and retrieval of data that is modeled in a way other than the tabular relations used in the traditional databases (RDBMS). The most popular database that makes use of the NoSQL technology is MongoDB. It functions as a cross-platform document-oriented database. It is known for its ability to provide high availability of replica sets. A replica set is nothing but a bundle of two or more copies of the data
