Networking is the practice of connecting computers and other devices to share resources and information. It involves both hardware (such as routers and switches) and software (such as protocols and operating systems).

Network security involves protecting the integrity, confidentiality, and availability of data as it is transmitted and received across a network. It aims to prevent unauthorized access, misuse, or destruction of data.

Understanding these fundamentals will give you a solid foundation in both networking and security, setting the stage for more advanced concepts as you dive deeper into these fields.
