Computer science is behind everything from the numerical analysis needed to make Covid's antidote to submitting electricity bills at home, using GPS in a car to find a place to communicate with a friend or relative in a distant country.
Of course, mobile or computer also helps us in many household chores. In the last 20-25 years, with the advancement of technology, the world of computer science has expanded in a way that has opened a new career path to the new generation.
Let me give you an example. With just a few mouse clicks, we can buy products of our choice from any e-commerce website. But behind the mouse click, the events that happen one after the other, the things that you like come to your house, you do not even notice.
The first thing you need to look for is an e-commerce website. That request immediately goes to a computer in a distant country. From the list of millions of product information out there, more products like your favorite product can be found in a blink of an eye. Various 'algorithms' help in these.
If you want to buy the product of your choice this time, add it to the e-cart. Money is then exchanged through a third party financial transaction portal. Millions of rupees are transacted online in the world every day. Needless to say, this would not have been possible if the transaction had not been secure enough. Behind this security are the theories of ‘cryptography’ and ‘network security’, which are taught in computer science classes. E-commerce websites also recommend buying other items in line with what you buy. Behind this is the theory of 'recommendation systems'. Web technology makes the whole thing possible. Knowledge of computer science is the main tool of those who are working behind the scenes to enhance your e-commerce website experience.
As the needs of our lives change over time, so do our daily problems. In the words of Bill Gates, co-founder of Microsoft, "The computer was born to solve a new generation of new problems." As a result, knowledge of computer science is very necessary in today's world. Think for yourself if you are interested in it.
