Read more →3 Programs
Programs make it possible to use a computer’s hardware components to perform the user’s digital operations. A device’s software consists of several levels. This is necessary for …
Read more →4 Principles of computer computation
Electrical voltage can be used to transmit digital values. Abstractly: there is voltage (higher voltage) = on state = 1; no voltage (lower voltage) = off state = 0. This fully fits …
Read more →5 Principles of network connectivity
Connectivity between computers is possible by means of network protocols. Large blocks of data are not transmitted as a continuous stream. Using information exchange protocols, …
Read more →6 Virtualization
Virtualization of computing resources makes it possible to run isolated environments on shared physical hardware. This chapter will be expanded.
