Answer 1

1ans:digital revolution makes huge impact on technology.in olden days we had only analog technology.analog values are 0 to 255. that makes the signal.but in digital we had only two signals high and low or binary zero or one.only two values there in digital 0 or 1.

2ans:digital data represented 0 or 1 only.sequence of 0 or 1 makes signal

each data we can represent in digital format only for example integer data 2 bytes that means 16bits

1bit=0 or 1

16 combination of 0 or 1 makes the integer.

we can represent 2^16 numbers by using n bytes like that based on the bytes we can represent the data

3ans:

accuracy and accessibility are advantages of digital data

4ans:data processing is nothing but retrieve the data and transform or classify the data.data is is any format either numeric data or image or video any kind of data.we need take the data and capture the data and observe the data and finally classify the data.

5ans:

first digital technology is shift from mechanical to digital electronics.in olden days only mechanical people can invented the any new object.but present every thing invented of based on digital electronics without human robots build the objects like mobiles or any electronic gadget.present most of sensors are invented this are very sensitive if we give analog data it will be destroyed.so thats why digital technology revolution done very rapidly

6ans:cloud computing are very useful for speed data transfer.while we are playing any game or watching any online video,we need speed of data transfer rate.our servers must be need sent the data very rapidly.our normal computers not capable to

process the huge amount of data.by using cloud computing technology we can do that kind of operations

7ans:server is the centralized system or router,their work is gather the information those who are connected to that server or router.like that cloud computing also give virtual machine to us.all are connected to the cloud and do their works without delay,.how huge amount of data is there.there is no problem to process the data

8ans:

IoT(internet of things)

by using iot technology we can control any electronic device from any where in the world.

examples:

home automation system

we can stop the fan where is located in the home but we can stop from anywhere in the world.by using mobile app if we press off on the app the fan will be stopped .if we press on the app it will working.
