Course Overview

Basic knowledge of the Internet V.1.1. Course Topics

1. Basic concepts and architecture of the Internet

1.1. What is the Internet and where is it located in ICT?

1.2. Physical and logical structure of the Internet (Network of Networks) (Done)

2. Data transfer and practical network diagnostics

2.1. Data packets and protocols (How is data fragmented? IP, TCP, UDP funds)

2.2. Process of data transmission (Role of routers, operation of the TCP/IP model from source to destination)

2.3. Network diagnostics in everyday life (Let's look behind the scenes: a ping and a traceroute practical use)

3. The Domain Name System (DNS)

3.1. What is DNA and how does it work? (The role of the translation agency, queries from the root servers to the browser)

3.2. Network protection at DNS level (How to use DNS to filter and block malicious pages)

4. Web operation, cloud and data sovereignty

4.1. Web servers and web language (role of HTML, CSS and JS, client-server communication)

4.2. Secure data exchange: HTTP vs. HTTPS (What's the difference and why SSL/TLS is now mandatory?)

4.3. Data sovereignty and self-hosted systems (Public cloud vs. own server, vendor lock-in avoidance. For example, run a Paperless document manager on your own Apollo, or separate development environments to Cronos.)

5. Internet services and applications

5.1. Email systems and file transfer (How does the mail travel? SMTP, IMAP, POP3 and FTP basics)

5.2. Streaming and cloud services (Operation of video-sharing and the modern SaaS, i.e. the software-as-a-service model)

6. Security on the Internet and the User's Responsibility

6.1. The most common modern threats (data theft, hacking, malware and social engineering)

6.2. User protection in practice (The correct implementation of password managers and the life-saving role of 2FA/MFA authentication)

7. Future technologies and data protection challenges

7.1. Internet of Things (IoT) and 5G (All Networked: balance of comfort and vulnerability)

7.2. Artificial Intelligence on the Internet (Locally run AI models vs. privacy and business risks of public cloud LLM solutions)
