Friend,
Although human is the ultimate , and complex machine ever built , it is the human which has given inteligence to the computer , but computers are essential to perform tasks much more faster then humans.
Thats cuz they have millions of transistors , which perform the task much more effectively and in milliseconds.
And humans if do the same operation again and again , they loose interest and get fedup , but a computer dose not.
In simple words we can say , they have there brain working at full speed and capacity , as compare to a human who cannot use 100% of his brain , in fact a average person uses only 8 to 12 % of his brain during his life span.
In modern times , computer literacy is essential for every person , i will like to encourage our baloch kids , brothers , sisters , to learn and spread the knowledge.
Mereen Baluch , Thanks for starting such a informative topic.
