Answer:
True.
Explanation:
Microsoft Word refers to a word processing software application or program developed by Microsoft Inc. to enable its users to type, format and save text-based documents.
In Computer science, there are specific key combinations (short cut) that avail end users the opportunity to perform specific functions without having to go through a series of step.
For example, when you press the Alt button and function key 4 (F4) at the same time, it would close the current open window.
Hence, Alt + F4 is a short cut key that can be used to close a document in MS word.
Answer:
for count in range (5,8): numA=numA+count print(numA)
Explanation:
When a formula produces output that is too lengthy to fit in the spreadsheet cell, the error that will show is "#####". When you enter an invalid cell reference in a formula, for instance using "AVE(" instead of "AVERAGE("; the error that will show is "#NAME?". When you type text in cells that accept numeric data, for instance adding 1 + 1 + A; then the error that will show is "#VALUE". Lastly, when you type in a cell reference that does not exist, the error that will show is "#REF".
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:
1. FDD is a process and Analysts can use a FDD to create and use business functions and processes. It Requirements models are used when gathering requirements for a new system.
2. BPM is used on an ongoing basis for business process improvement. It is meant to improve order, insight and efficiency of the collective workflows that make up any given business process. BPM is meant to reduce any chaos within those collective workflows that make up a process and eliminate ad hoc workflow management. BPM means Business Process Management.
3. DFDs stands for Data Flow Diagram which will help software developers and designers to understand how they can take their next step to fit into the overall business process. DFDs paly key role for a successful requirements modeling.
4. UML can be used for modeling a system independent of a platform language. UML is a graphical language for visualizing, specifying, constructing, and documenting information about software-intensive systems. UML gives a standard way to write a system model, covering conceptual ideas.
Explanation:
Functional decomposition diagram (FDD) is used to identify functions and define their structure. It is a technique to decompose the complex problem into manageable pieces or individual elements to develop the application or product.
DFDs: It contains a process (shape) that represents the system to model, in this case, the "Food Ordering System". It also shows the participants who will interact with the system, called the external entities. In this example, Supplier, Kitchen, Manager and Customer are the entities who will interact with the system.
Unified Modeling Language (UML): Edraw UML Diagram is the application of choice for many software engineers and designers. The software is fully compatible with 64 and 32-bit Windows platforms from Windows XP to Windows 10.
