Answer:
a. facilitate improvements but do not necessarily cause them.
Explanation:
Decision Support Systems are interactive Information systems that assist decision makers in coming up with strategies that help the organisation achieve its goals .The model base of the DSS uses mathematical and statistical models to analyse information then it generates reports and suggest possible solutions that can be implemented .The system is capable of giving a specific solution and some even allow the decision makers to give input before suggesting the most applicable solution.The effectiveness of a DSS is equally as important as its efficiency .The DSS unlike the conventional decision-making process should be able to analyse information effectively and come up with solutions in the shortest possible time frame.
Answer:
The answer is "2".
Explanation:
In the given question some information is missing, that is "The propagation time for satellite to earth" which is "270 milliseconds" so, the description to this question can be defined as follows:
Given values:
Bandwidth = 64 kbps
Data frames = 512 bytes
Propagation Time (tp ) =270 ms
Change Bandwidth kbps to bps:
1 kb= 1024 bytes
calculated bandwidth= 64 kbps = 64×1024 bps = 65536 bps
1 bytes = 8 bits
512 bytes = 512 × 8 = 4096 bits
Frame length = 4096 bits
Formula
Transmission time (Tt) = Frame length /Bandwidth
Window size = 1+2a
where a = Propagation time/Transmission time
Calculate Transmission time:
Transmission time (Tt) = 4096 / 65536
Transmission time (Tt)= 625 m.sec
Calculate Window size:
Window size = 1+2(270/625)
Window size
= 1+2(0.432)
Window size
= 1+0.864
Window size = 1.864
Window size
= 2

Answer:
Option B is the correct answer for the above question.
Explanation:
The control structure is a decision type structure which can be either true or false. It has two options-- If this then, does this otherwise do this. When the user wants to write he control structure then he can do this by the help of the following syntax in python language--
if(condition):
do this
else:
do this
The above question wants to ask about the concept which is used in the programming for a decision then the answer is control structure which is referred from the option B. Hence B is the correct option while the other is not because--
- Option A states about the flowchart which is the picture form of the instruction.
- Option C states about the pseudocode which is the language form of the instruction.
- The operator is also not the correct option because it is used to perform the operation.
