Editor's Notes
- #8 Mach provides memory management; support for remote procedure calls (RPCs) and interprocess communication (IPC) facilities, including message passing; and thread scheduling. The BSD component provides a BSD command-line interface, support for networking and file systems, and an implementation of POSIX APIs, including Pthreads. I/O kit for development of device drivers and dynamically loadable modules (which Mac OS X refers to as kernel extensions)
- #9 Cocoa Touch is an API for Objective-C that provides several frameworks for developing applications that run on iOS devices. The media services layer provides services for graphics, audio, and video. The core services layer provides a variety of features, including support for cloud computing and databases. The bottom layered presents the core operating system, which is based on the kernel environment of MAC OS X.
- #10 Linux is used primarily for process, memory, and device-driver support for hardware and has been expanded to include power management. frameworks for developing web browsers (webkit), database support (SQLite), and multimedia. The libc library is similar to the standard C library but is much smaller and has been designed for the slower CPUs that characterize mobile devices.
