Network

A network refers to a collection of two or more computers, or other electronic devices, that are connected via physical cables or wireless signals. This connection allows the devices to communicate and share resources such as data, files, printers, and internet access. The primary purpose of a network is to facilitate the exchange of information and enable data communications among users and devices.

Networks can be categorized based on their geographical scope and the technologies they employ:

The design and management of networks involve various devices such as routers, switches, and hubs, which help in directing and managing the traffic within the network. Security measures such as firewalls, encryption, and secure passwords are also integral to protect data and maintain the integrity and confidentiality of information as it travels across the network.

Overall, networks are foundational to modern communication, enabling not only the internet but also the myriad of enterprise, home, and mobile applications that rely on fast and reliable data exchange.
