Question 3
(a) Using the AIT Lemass as an example, discuss practically the Quality of Service (QoS) levels in the areas that are measured when determining 3 the performance of a system. If any of the areas measured has a poor quality of service, discuss what could be done to improve upon its quality of service.
(b) Discuss practically the server form factor(s) you would consider for AIT and justify your choice with reasons
(c) Using the AIT Internet provision for lectures to be streamed online as a case study, discuss the kind(s) of challenge(s) faced by lecturers (e.g IT101) using the Internet service(s) provided by the school for the online streaming and its impact on students (both on campus and at home/hostel). Discuss what you think could be done to resolve such challenge(s)..
Given a sorted array of distinct integers and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order.
Ex 1:
Input: num = [1,3,5,6], target = 5
Out: 2
Ex 2:
Input: num = [1,3,5,6], target = 2
Out: 1
Ex 3:
Input: num = [1,3,5,6], target = 7
Out: 4
Ex 4:
Input: num = [1,3,5,6], target = 0
Out: 0
Ex 5:
Input: num = [1], target = 0
Out: 0
please follow the below program finish it in C language.
#include <stdio.h>
#include <stdlib.h>
int nums[1024];
int main(){
FILE *fp;
fp=fopen("binarysearch.txt","r");
if(fp==NULL){
printf("The input file does not exist.\n");
exit(-1);
}
int target,size = 0,i;
fscanf(fp, "%d", &target);
while (!feof(fp)){
fscanf(fp, "%d", &(nums[size]));
size ++;
