• Based on the presentation last Friday, what were the circumstances that drove the people during that time to developed technologies towards inter-networks? 

before in 1957 all computers worked only on one task at a time, and they called it batch processing. they invented many things so that people can easily use the computers, and after many years, they finally invented the new technology, "the Internet".

• How did the different technologies contribute to the evolution of the modern Internet?   

the different technologies before contributes a lot to our modern internet today, because technologies before are working very slow. that's why they give idea to the people to invent new. and they discovered the internet. 

• If you could change or improve something in the internet and/or its services, what would it be?

 If i have a chance to change or improve something in the internet, it would be the speed of the internet when it is raining. because sometimes when it rains our internet is very slow, sometimes it is not running or working.
