Answer:
Let's take an example of the embedded system, which is a perfect example of this question as a computer system. Suppose we want the embedded system to record the details related to soil of agricultural land. We will take an IoT device which will be a sensor that can register soil properties, and get connected to the computer system through the internet. And we design an embedded system that registers these values and then copy them like somewhere in DB space on Amazon cloud or Google cloud. And finally display on some LCD or a big projector, or whatever, and like we design. Thus we have designed, and now when we install this on agriculture land, we implement it, and since check regular for correct performance, we maintain this embedded or a mini-computer system as well. This is what design, implement and maintain computer systems mean.

They are needed because of the following reasons :
》The storage capacity of primary memory is limited.
》 Primary memory (RAM) is volatile in nature.
》 RAM is not portable memory.
》 RAM chips are expensive. Increasing RAM will increase the price of the computer.
So, for the above reasons we need to use the Secondary memory devices.

Every image editing software has a crop tool that allows you to trim or eliminate the edges of an image. Cropping tools in Ms.word allow you to hide portions of picture that you do not want to be displayed in the final result.
Answer:
The output of the following code is 3.
Explanation:
In the following Python Programming Language, the output is 3 because the variable x is equal to 21, then the user check the condition is the variable x is greater than 21 then print it print 1, otherwise the user check that the variable x is less than 21 then print 2, otherwise it print 3. So, the variable x is not greater than 21 or not less than 21, it is equal to 21. That's why the code execute the else block and print 3.
