Hey mate ,
Here is your answer
1) a) INTERNET
A global computer network which provides variety of information and communication facilities consisting of interconnected network using standardized communication protocols.
b) Who controls it ?

2) Device ??
a) Which device?
An analog to digital converter ( ADC ) is a device that converts digital signals into analog signals for transmission of telephone lines.
b) Why is it Necessary ?
Telephones work on the same principle. If ADC device is not there then we couldn't convert the digital signals into analog signals. Telephones couldn't have come to use so its very important

1.The internet is a globally connected network system that uses TCP/IP to transmit data via various types of media. The internet is a network of global exchanges – including private, public, business, academic and government networks – connected by guided, wireless and fiber-optic technologies.
The terms internet and World Wide Web are often used interchangeably, but they are not exactly the same thing; the internet refers to the global communication system, including hardware and infrastructure, while the web is one of the services communicated over the internet.
2. a modem
it is necessary because communication channel carry analog signals. But computer generated data is digital. so modem converts it . also computers cannot understand analogue signals.
