Chapter 1
Functioning of the computer, programs and documents, the importance of the operating system
A basic chapter in which you learn how computers work. Fortunately, it's not too complicated, the basic principle of how computers work, valid for more than 70 years, comes from the cooperation of only three basic parts.
- 1.1 Basic (three) computer parts and their functions
- 1.2 Programs and documents, data storage. Computer operating principle
- 1.3 Composition of the current computer, terms HW, SW
- 1.4 Operating systems (OS)
- 1.5 Link of operating system control to the computer operating principle
- 1.6 Folder structure
- Open Chapter 1 lessons
Chapter 2
LOCAL AREA NETWORK AND INTERNET
A computer that is not connected to some kind of network today is more or less useless. Here you will learn how both local area networks (LANs) and worldwide networks (the Internet) work.
- 2.1 Types, services and importance of LANs
- 2.2 Technical operation of LANs, packet data transmission, IP address
- 2.3 Origin, composition and principles of the Internet
- 2.4 Extension: LAN to Internet routing, firewall
- 2.5 Datacenters, cloud
- 2.6 GSM and GPS networks
- Open Chapter 2 lessons
Chapter 3
WEB, BROWSERS, SECURITY AND PRIVACY

- 5.3 Attackers' targets and methods
- 5.4 Technical computer security
- 5.5 Data backup and archiving
- 5.6 System approach to computer security
Chapter 6
DATA ENCODING AND COMPRESSION, HARDWARE
A computer is a digital device, it uses a binary system... What this means and how computers encode data is the focus of this chapter.

- 6.9 HW: Ports and connectors - what to connect where
- 6.10 Expansion: Current hardware
- Open Chapter 6 lessons
Chapter 7
BREAKTHROUGH MOMENTS IN HARDWARE AND SOFTWARE DEVELOPMENT
Technology didn't suddenly appear in the year 2000; the first efforts at automated computing date back more than 150 years. The way technology has evolved also implies many important things for its current use.
- 7.1 Abacus, Analytical Engine, the first computers
