The first time I used internet was with a Nokia java phone. Speed was 16KB and I was using only some websites to download "pirated" music or funny videos. I didn't knew then how piracy worked. Didn't know how to avoid it. Its been more than 10 years. The internet we have now is far more sophisticated.
Internet has impacted the most is how I learn things. Then I had to read books after books to find relevant materials. But now I can get that with some little monthly subscription fee. Another part it has impacted is communication. Before using the Internet as a communication method I used to text people and had to pay a overpriced tag. And now facebook or other social media apps has made that so easy.. Now I can use Internet to answer peoples "questions" on musing instantly no matter how far they are from me.. I think that's sufficient to prove how internet has changed my life.
