There are four different driver bridges or JDBC drivers defined by the JDBC specification from Sun.

Task Scheduling Algorithms in C
1. Min-Min Algorithm
#include
#includevoid main() {
int nT, nM; // number of tasks, number of machines
printf("\nEnter the number of machines and tasks: ");
scanf("%d%d", &nM, &nT);// Declare a 2D array of size nM x nT
// Data should be in the following format:
// T1 T2 T3
// M1 | 140 | 20 | 60 |
// M2 | 100 | 100 | 70 |
int min_min[nM][nT];
int tmp[nM][nT];
int makespan = 0;printf("\nFill Data:\n");
for (int i = 0; i < nM; i++) {
for (int j = 0; j < nT;

Common Threats
1. Zero-Day Exploits
- Definition: Targeting undisclosed software flaws, zero-day exploits vulnerabilities before developers can provide patches, posing a heightened risk due to the absence of immediate defenses.
2. Worms
- Definition: Autonomous malware, worms spread across networks without user interaction, exploiting vulnerabilities. They pose serious threats by rapidly infecting systems and consuming network resources.
