hardware of the computer display (what you see)
- Operating systems give programmers a common set of commands to
consistently interact with the hardware
- Good OS and software can catalyze network effects (Eg apple apps)
- Firmware: control programs stored on chips -- > smaller, special-purpose
computing devices EG OS in an iPod, mobile phone, or TV box
- Embedded system: special software designed and included in physical
products. Often stored as firmware too.
- Moore’s Law enables embedded systems
- Platform: operating systems create a platform so that programmers can
write additional applications. EG iPhone, Wii, windows.
- Application software: performs the work that users and firms are directly
interested in accomplishing --- the more application software that is available
for a platform (eg more apps for your phone), the more valuable it
potentially becomes.
