A computer network is a set of computers that are connected together so that they can share resources. The most common resources shared are files and internet access. The computers on a network can be connected through cables, telephone lines, radio waves, satellites, or infrared light beams.

The process of setting up a computer network is called network architecture. It involves several key components, including:

1. Nodes: These are the individual computers connected to the network, also known as network devices. They can include personal computers, servers, phones, routers, switches, or other devices.

2. Network Connections: These are the links that connect the nodes. They can be physical, like cables, or wireless, like Wi-Fi or cellular signals.

3. Network Protocols: These are the rules and conventions for communication between network devices. Protocols define the processes and methodology for data exchange, including error checking, data compression, and data rates.

The Internet has had a profound impact on the world, changing the way we work, learn, communicate, and entertain ourselves. Here are a few ways the Internet has changed the world:

1. Communication: The Internet has made it easier than ever to communicate with people all over the world. Email, social media, video conferencing, and instant messaging have all made communication faster and more efficient.

2. Information Access: The Internet has made a vast amount of information available at our fingertips. We can access news, research, statistics, historical information, and more from anywhere in the world.

3. Education: Online learning has become a reality thanks to the Internet. Students can now take courses from universities all over the world, and access resources and materials that may not be available locally.

4. Business: The Internet has transformed the business world, enabling e-commerce, online marketing, and global collaboration. It has also made it possible for small businesses and entrepreneurs to reach a global market.

5. Entertainment: The Internet has revolutionized entertainment, with streaming services, online gaming, and social media providing new ways to relax and have fun.

In conclusion, a computer network is a system of interconnected computers that share resources and information. The Internet, as a global network of networks, has significantly impacted various aspects of our lives, including communication, information access, education, business, and entertainment.
