The scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. The scientific inquiry is a way to investigate things and purpose explanation for their observations. Data is gathered, hypothesis suggested, and observations recorded.

Several different troubleshooting methods already exist but according to CompTIA; there are six steps to solve a problem. Drawing a parallel these steps are all included into the scientific method, but how?

Scientific method CompTIA troubleshooting Method, Ask a Question - Identify the problem, Do Background research - Establish a theory of probable cause, Construct Hypothesis Test - the theory to determine the cause, Test your hypothesis by Doing experiment - Establish a plan of action to resolve the problem and implement a solution, Analyze your Data and draw a Conclusion - Verify full system functionality and if applicable implement preventive solution, Communicate your result Document -findings, actions, and outcomes.

How these affect our daily job, life or activities?

In the Information Technologies (IT) field, we are constantly using the scientific method to solve various problems. Let take a real example: One of ours customer called and state that her computer stop to working this morning. But yesterday before she left her office the computer was working well, this morning she cannot access to the internet or even the website of the company.

1. In this case we need first to identify the problem, to do that we ask some basic questions, what was the last thing that she remember having done, when? Is the computer connect in a network environment, did she turned the computer off? Did someone else have access to the computer? Any question, response or information provided this time will be helpful to identify the problem. In our situation the computer is in the office with network infrastructure, the computer is in the open place easily accessible by another employee, and the problem is connectivity.

2. The second step will be the why? Because the customer said: the computer was working well yesterday; they are in the network environment, and someone else might use the computer it could be a software problem. In this step, we can build a variety of hypothesis on what happening or can happen in this or that situation. Therefore why a computer does not connect?  The problem might be the network card, the switch or router, maybe the internal protocol (IP) address is misconfigured, maybe the driver is corrupted.  The scientist view will assimilate that to emitting hypothesis.

3. Theories of probable cause (hypothesis): For the purpose of this assignment, let assume that probably the Network Interface Card is faulty, then we need experiment to support our thoughts. The network interface controller (NIC) also called Network Card is a piece of hardware that connects a computer to a network. There are two common culprits for network interface card failure; one will affects the NIC hardware, and another which damages software associated with the NIC card. These are known as power surges and malware.

Power surges are short, fast spikes in the electricity being supplied to a power outlet. They are most likely caused by lightning strikes, the power outages, short circuits, electromagnetic pulses, turning on or off large machines which share the same power line.  All the computers plugged in the same outlet, or into the same switch or router are affected by the power surges.
            The other common culprit of internal network card failure is malware. Given the crucial role that NIC cards play in connecting computers to networks, network cards are a major target
