Answer:

b. Synchronous replication

Explanation:

Replication of data in storage partitions or in a number redundant array of independent disk drives helps to promote redundancy, as implied, and faulty tolerance to reduce loss of data.

There are two categories of replication and they are synchronous and asynchronous replication.

Synchronous replication requires low latency network site to mirror data, while asynchronous replication mirrors data in large metropolitan area in high latency networks.

2) Please create a C program for the following: (25 points) a. Suppose the US dollar to Korean Won is 0.85 dollars to 1000 won.
Zanzabum

Answer:

In C:

#include <stdio.h>

int main(){

       float won,usd,rupee,dinar,peso;

       printf("Won: ");

       scanf("%f", &won);

       usd = won * 0.85/1000;

       rupee = won * 0.85 * 0.14/1000;

       dinar = won * 0.85 * 0.048/1000;

       peso = won * 0.85 * 1.41/1000;

       printf("USD = %f\n", usd);

       printf("Rupee = %f\n", rupee);

       printf("Dinar = %f\n", dinar);

       printf("Peso = %f\n", peso);

   return 0;

}

Explanation:

This declares all variables as float

float won,usd,rupee,dinar,peso;

This prompts the user for Korean Won

       printf("Won: ");

This gets the input for won

       scanf("%f", &won);

This converts to usd

       usd = won * 0.85/1000;

This converts to rupee

       rupee = won * 0.85 * 0.14/1000;

This converts to dinar

       dinar = won * 0.85 * 0.048/1000;

This converts to peso

       peso = won * 0.85 * 1.41/1000;

The next four lines print the converted currencies

       printf("USD = %f\n", usd);

       printf("Rupee = %f\n", rupee);

       printf("Dinar = %f\n", dinar);

       printf("Peso = %f\n", peso);

A device is sending out data at the rate of 1000 bps. How long does it take to send
vredina [299]

Answer:

0.01 second ; 0.008 seconds; 800 seconds

Explanation:

Given that:

Sending rate = 1000 bps

Rate of 1000 bps means that data is sent at a rate of 1000 bits per second

Hence, to send out 10 bits

1000 bits = 1 second

10 bits = x

1000x = 10

x = 10 / 1000

x = 0.01 second

2.)

A single character 8 - bits

1000 bits = 1 second

8 bits = (8 / 1000) seconds

= 0.008 seconds

3.)

100,000 characters = (8 * 100,000) = 800,000

1000 bits = 1 second

800,000 bits = (800,000 / 1000)

= 800 seconds
