Explain the importance of networking standards
Protocols - A set of rules which govern communication.
Devices can only communicate if they are using the same protocols as each other, similar to how humans can only effectively communicate if they speak the same language.
Different protocols serve different purposes, like for sending web resources, emails, the transmission media, how data is formatted, etc.
Layer - a group of protocols that serve a specific function in network communication.
Layers are useful for splitting up the complex task of network communication into smaller, easier-to-deal-with chunks. Each layer can be developed independently of each other.
