Create a computer network: Terminology, NIC, Computer Network and Network Protocol

The video tutorial introduces key networking concepts, starting with the importance of understanding terms and communication methods. It explains the role of network interface cards (NICs) in connecting devices to networks, both wired and wireless. The tutorial highlights the basic concept of a computer network as two devices sharing information and introduces network protocols as the rules governing communication between devices. The video also mentions the OSI model, which defines layers of networking protocols.

Describe the analogy used to explain network protocols in everyday life.

What is the Open Systems Interconnection (OSI) model and how many layers does it define?
