Installable device drivers allow the OS to support new devices without updating the OS.
The Google Chrome OS is primarily aimed at smaller devices such as NetBooks rather than desktop type PCs. The OS will run on hardware incorporating an x86 or ARM-based processor and Google suggests the use of solid-state drives rather than standard hard discs although the OS can support both.
Omnigaffle is a charting software, similar to Microsoft Visio. Omnigaffle is compatible with Apple devices: Mac OS X Leopard, Mac OS X Snow Leopard, Mac OS X Lion and iOS (iPad).
The operating system (OS) manages input and output devices through a system of device drivers and a unified interface. Device drivers are specialized programs that translate OS commands into device-specific operations, enabling communication between hardware and software. The OS uses a layered architecture to abstract device operations, allowing applications to interact with I/O devices without needing to know the details of their implementations. Additionally, the OS employs buffering, caching, and scheduling techniques to optimize data transfer and resource management for these devices.
Though Google Play (previously called Android Market) is generally available for Android OS 2.2 and above, it may be limited for use on devices with Android 2.1, and/or the device itself might not be compatible to use it.
If your taking about installing an OS, you will definitely need hard drive. But for storing files, you can always use Removable Devices, USB Flash Drive or CD-Rs.
