IT in a Nutshell

These are the basic things in Information Technology:

1. Physicalization (hardware abstraction)

  • OS (operating system)
  • Desktop virtualization (Virtualbox)
  • Server virtualization (ProxMox)

2. Virtualization (service abstraction aka cloud computing)

  • IaaS (infrastructure as a service)
  • PaaS (platform as a service)
  • SaaS (software as a service)

3. Client/server architecture

4. Peer-to-peer architecture

5. Programming (compiler)

6 Scripting (interpreter)

7. Virtual machine (VM) coding (JVM, .NET)

IT revolves around these basic units of computing.
