The Internet
The Internet is a global network of interconnected computers that communicate using standardized protocols.
Key Concepts:
- Protocols: Rules for communication (e.g., HTTP, FTP).
- IP Addressing: Unique identifiers for devices.
- Routing: Directing Data packets through interconnected networks.
Components:
- DNS: Converts human-readable names to IP addresses.
- TCP/IP: Ensures reliable transmission of data.
Security Concerns:
- Vulnerabilities such as DDoS attacks or phishing.
- Solutions include encryption, authentication, and safe algorithms.
