Demystifying Computer Networks.

Before we connect the dots and explore the world of computer networks, it's essential to understand the basic concept of what the term 'computer network' actually means.

In simple words, we can understand it as when two or more computers are connected to each other for the purpose of sharing data or resources. This connection allows these devices to communicate and share information, and collectively, they create a computer network.

For example: - In a computer network, a sender machine can send a message or data to a receiver machine, and this communication occurs through a connection, which can be either wired (e.g., Ethernet cable) or wireless (e.g., Wi-Fi or cellular network). The data travels from the sender to the receiver over this connection.
