1. How did the Internet evolve?
The internet, also called the Net, is a worldwide collection of networks that links millions of business, government agencies, educational institutions, and individuals. The Internet has its roots in a networking project started by the Pentagon’s Advanced Research Projects Agency (ARPA), an agency of the US Department of Defense. ARPA’s goal was to build a network that allowed scientists at different locations to share information and work together on military and scientific projects and could function even if part of the network were disabled or destroyed by a disaster such as a nuclear attack. The network called ARPANET, became functional in September 1969, linking scientific and academic researchers across the United States.
As researchers and others realized the great benefit of using ARPANET to share data and information, ARPANET underwent phenomenal growth. By 1984, ARPANET had more than 1000 individual computers linked as hosts. Today more than 550 million hosts connect to the internet.
Some organizations connected entire networks to ARPANET to take advantage of its high-speed communications. In 1986, the National Science Foundation (NSF) connected its huge network of five supercomputer centers, called NSFnet, to ARPANET. This configuration of complex networks and hosts became known as the internet.

Why Is Computer Literacy Vital in Today’s World? 
Computer literacy is important and essential in today's world as much of the world relies on computers for doing the day-to-day activities. Computer literacy is the knowledge and the ability to use the computers and technology efficiently. The goal of every computer literate person is to be able to use and learn the computer programs without much help. As computers become more a part of everyday life, many people believe that computer literacy is vital to success.

What Is a Computer, and What Is the Relationship between Data and Information?
A computer is an electronic device, operating under the control of instructions stored in its own memory, that can accept data, process the data according to specified rules, produce results, and store the results for future use. The relationship that lies between data and information is a solid one. Data is termed as raw facts such as phone numbers or addresses, while on the other hand information is the actual organization of these raw facts in a meaningful manner. This information may be in the form of a well-organized report or table and but not always be meaningful to everyone. Data is a collection of unprocessed items, which can include text, numbers, images, audio, and video. Information conveys meaning and is useful to people.
