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

While using a Web-based order form, an attacker enters an unusually large value in the Quantity field. The value she entered is

maxonik [38]

Answer: integer overflow

Explanation:

The type of attack has occurred in this scenario is a integer overflow. An integer overflow occurs when there's an attempt by an arithmetic operation to create a numeric value which is outside the range which the given numbers are able to represent.

In this, the integer overflow occurs when the result of the integer operation cannot be able to fit in the allocated memory space which then brings about an unexpected result.

I believe it is corn. ethanol can be produced from corn biomass, and is commonly used to make gasoline. i’m not sure if this answers your question, or counts as a type of energy but i tried.

What happens if you try to compile and run this program?

Lynna [10]

Your question is poorly formatted

#include <stdio.h>

int main(void) {

int i, t[4];

t[3] = 0;

for (i = 1; i >= 0; i--)

t[i] = t[3] * i;

printf("%d", +t[1]);

return 0;

}

Answer:

It outputs 0

Explanation:

I'll start my explanation from the third line

This line declares an integer variable i and an array of 4 elements of type integer

int i, t[4];

This line initialize the 3rd index element to 0

t[3] = 0;

The next two lines is an iteration;

The first line of the iteration iterates the value of i in descending order from 1 to 0

for (i = 1; i >= 0; i--)

This line of the iteration calculates t[1] as t[3] * i and t[0] as t[3] * i; Since t[3] is 0; both t[1] and t[0] will be 0

t[i] = t[3] * i;

This line prints t[1] which is 0

printf("%d", +t[1]);
