Answer:
HDLC is one of the most commonly used internet protocols (IP) in what is Layer 2 of the industry communication reference model called Open Systems Interconnection (OSI).
Explanation:
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:
<em>Internet backbone</em>
Explanation:
The internet backbone is made up of multiple networks from multiple users. It is the central data route between interconnected computer networks and core routers of the Internet on the large scale. This backbone does not have a unique central control or policies, and is hosted by big government, research and academic institutes, commercial organisations etc. Although it is governed by the principle of settlement-free peering, in which providers privately negotiate interconnection agreements, moves have been made to ensure that no particular internet backbone provider grows too large as to dominate the backbone market.
Answer:
The answer is "Actual products".
Explanation:
The key purpose of this research is to better analyze the concepts, which is done to establish customer buying expectations and perceptions of the item. The key point is to assess the consumers ' initial response to the product idea.
- This concept testing is also known as a creation, it is an advantage, which can be conveyed to the user to test their reactions.
- In conceptual testing, it is a quality check between the design definition and the actual production of the product.
