Answer:
t= 8.7*10⁻⁴ sec.
Explanation:
If the signal were able to traverse this distance at an infinite speed, the propagation delay would be zero.
As this is not possible, (the maximum speed of interactions in the universe is equal to the speed of light), there will be a finite propagation delay.
Assuming that the signal propagates at a constant speed, which is equal to 2.3*10⁸ m/s (due to the characteristics of the cable, it is not the same as if it were propagating in vaccum, at 3.0*10⁸ m/s), the time taken to the signal to traverse the 200 km, which is equal to the propagation delay, can be found applying the average velocity definition:
If we choose x₀ = 0 and t₀ =0, and replace v= 2.3*10⁸ m/s, and xf=2*10⁵ m, we can solve for t:
⇒ t = 8.7*10⁻⁴ sec.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is the planning stage. Because the planning stage represents the development of documents that provide the basis for acquiring the resources and for developing the requirement document. at this stage, you plan about what you are going to develop and how to develop it. At this stage, you come out mainly with two documents i.e. project proposal and requirement document.
Other options are not correct because:
In the project management, after planning, you will start designing the product, and after designing you start developing the product, and at the implementation stage, you implement or deploy the product to the customer or to the client. The requirement document that is developed at the planning stage can be used in the later stages of the project.
Answer:
d. To help security professionals better understand and protect against threats to the system
Explanation:
The main purpose of a honeypot is to attract potential hackers and allow them to have access to a network system that is not the actual live network with close monitoring. This is done so as to learn and understand the intentions of the hacker and how they execute an attack. With this knowledge security professional are in a better position to deal with potential threats and keep the network secure.
Answer TCP/IP is the most common protocol in Local Area Networks.
