Answer:
4
Explanation: All the other ones are a rushed way of storing files
Answer:
C. Binary can be used to represent more complex, higher level abstractions, including but not limited to numbers, characters, and colors. D. When data is large enough computers switch to using decimal representation instead of binary, because you can represent larger numbers with fewer digits
Explanation:
Answer: This is a python code
def lightyear():
rate=3*100000000 //speed of light
seconds=365*24*60*60 //number of seconds in 1 year
return str((rate*seconds)/1000)+" km" //distance=speed x time
print(lightyear()) //will print value of light hear in kilometers
OUTPUT :
9460800000000.0 km
Explanation:
In the above code, there is a variable rate, which stores the speed of light, i.e. distance traveled by light in 1 second which is in meters. Another variable is seconds, which store the number of seconds in 1 year, which is no of days in 1 year multiplied by the number of hours in a day multiplied by the number of minutes in an hour multiplied by the number of seconds in a minute. Finally, distance is speed multiplied by time, so distance is printed in kilometers and to convert distance in kilometers it is divided by 1000.
There are some function which can be performed with database but not with a spread sheet, these functions include:
1. Enforcement of data type.
2. Support for self documentation.
3. Defining the relationship among constraints in order to ensure consistency of data.
Answer: Business intelligence
Explanation:
Most of the enterprises and organizations collects huge amount of data through the use of MIS. These data can be based on any aspect of the business. But the collection of such large sets of data is useless until and unless there is a business intelligence associated with it. the work of business intelligence is to use software tools for analysis of the collected data so that it could be useful for enterprise or company to look for patterns and trends in the market.
The outcome of such business intelligence is very helpful particularly to managers, executives for taking particular decisions in the greater interest of the company.
So we can say, business intelligence is an approach to boundary spanning that results from using sophisticated software to search through large amounts of internal and external data to spot patterns, trends, and relationships that might be significant.
