Operating Systems by Mind Map: Operating Systems

1. Cellphone operating system

1.1. Pros: The largest library of programs and applications. Some commercial games work only with Windows and DirectX. Almost all hardware has drivers which are compatible with Windows. Most widely used.

1.2. Cons: Prone to viruses, spyware, and adware if proper steps not taken such as installation of internet security software, which reduces performance speed. Requires regular maintenance to avoid system errors and reduced performance. Even with maintenance, issues can slowly accumulate requiring a re-installation of Windows to restore performance and fix software issues. Purchasing a Windows license/install disk can be relatively expensive Windows Vista, the most recent version of Windows, has high system requirements.

2.2. Cons: 1) Accessories tend to be more expensive (hello TV tuners!). 2) Not compatible with a LOT of PC hardware. 3) Safari & FireFox on Mac don't work for all websites. 4) Command key is in an awkward position.
