Answer:
Two Dutch spectacle-makers and father-and-son team, Hans and Zacharias Janssen, create the first microscope in 1590.
Explanation:
A microscope is an instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by the unaided eye. The most familiar kind of microscope is the optical microscope, which uses visible light focused through lenses. Eeuwenhoek observed animal and plant tissue, human sperm and blood cells, minerals, fossils, and many other things that had never been seen before on a microscopic scale. He presented his findings to the Royal Society in London, where Robert Hooke was also making remarkable discoveries with a microscope.
Well, CEOs are on the top of the food chain. It takes a lot of work and ambition to become one, and once they are one, <span>CEOs accept a huge amount of responsibility - that means having to take blame if things go wrong and </span><span>having more tasks to complete such as having to attend numerous meetings, make decisions. They are also on the board of directors.</span>
Assistants do not have to do as much, they likely won't have that much responsibility or experience, their tasks revolve around ensuring meetings are scheduled and performing other ad-hoc duties.
Answer:
The programming code can be found in the explanation part, please go through it.
Explanation:
Code:
#include<stdio.h>
#include<stdlib.h>
#include <pthread.h>
// function check whether a number
// is prime or not
int isPrime(int n)
{
// Corner case
if (n <= 1)
return 0;
// Check from 2 to n-1
for (int i = 2; i < n; i++)
if (n % i == 0)
return 0;
return 1;
}
void* printPrimes(void *vargp)
{
int *n = (int *)vargp;
int i=0;
for (i=2;i<=n;i++)
{
if (isPrime(i)) printf("%d\n", i);
}
}
// Driver Program
int main(int argc, char* argv[])
{
int n = atoi(argv[1]);
pthread_t tid;
pthread_create(&tid, NULL, printPrimes, (void *)n);
pthread_exit(NULL);
return 0;
}
I think it should be in the design tab
That would be a star network. A star network isn't necessarily shaped like a star, of course, but like you mention this topology has a central device, usually a server of some sorts, and then many different endpoints coming out of that central device, such as the client computers for the server.
