Step-by-step explanation:
Networks are essential in computer systems because they enable communication and resource sharing between different devices and users. Through a network, computers can exchange data, access shared files and resources, and collaborate on projects. For example, in a local area network (LAN), computers in a school or office can connect to each other to share printers, access the internet, and transfer files.
In addition, networks are crucial for accessing the internet, which is a global network of networks. The internet allows users to connect to websites, send emails, stream videos, and engage in various online activities. It has revolutionized communication, commerce, and information sharing on a global scale.
Moreover, networks have played a significant role in the development and advancement of technology. They have paved the way for innovations such as cloud computing, online gaming, social media platforms, and remote collaboration tools. These technologies rely on networks to function and provide services to users.
