hello! I would like to thank you for your input. I remember the day when my father bought the next computer. It was a huge thing for me then, it was my first computer. It had 8mb of RAM. Now computers have 8GB of RAM. this change in 20 years is incredible. as you told in the beginning of your writing now we can buy 1TB hard drive for $50! ıt is a memory that no one in 1990s could have imagined. ın the future, no more than 20 years, maybe we will be able to use thousands of terrabites like we are using gigabites we are using today!
