Use the following rules:
- The sum of currents that enter and exit a node (junction) is always zero. So if you have 3 wires that connect, through one flows 2A, the other 3A, then the third must deliver 5A (taking the direction into account!)
- The sum of voltages across different components should always add up. So if you have a battery of 10V with two unknown resistors, and over one of the resistors is 4V, you know the other one has the remaining 6V.
- With resistors, V=I*R must hold.
With these basic rules you should get a long way!

From scientists planing to share information across countries. Letters and the mail system took to long for certain situations.
Answer:
Phishing means cyber theft in which the cyber thief sends the target PC a malicious email, which looks like coming from some known source, and they ask for certain critical information, which must not be leaked. Similarly, In ransomware, they send the phishing email with malicious code, and they hack the computer system. They then ask for a ransom as a return for reactivating your PC. Distributed Denial of service attack happens when the traffic flood the bandwidth and the resources of a PC, and finally a lot of are denied of access to them. Ransomware, when it attacks a bank account, becomes a Denial of service attack, as multiple users are stopped from accessing their account. All of these are hence, almost the same and revolves around the phishing email.
