Symbian is a joint venture (Motorola has withdrawn) from Motorola, Siemens, Nokia, and other large mobile communications equipment companies, which specializes in developing mobile operating systems. The Symbian OS's predecessor was EPOC, and Epoc Electronic Piece of cheese took the first letter, which was meant to be as simple as eating cheese when it was designed. Symbian is not just an operating

In fact, many times the abstract things and the real world of the phenomenon of analogy, a lot of confusing things are easy to understand.Process scheduling algorithmThe Process Control block (PCB) is also mentioned above, which stores information about the process, including scheduling information for the process. After the process is submitted to the operating system and not directly into the r

Unix. When executing the system call routine module, it involves the change of the processor operation state: The user state to the system state, and then returns to the user state after executing the routine procedure. The UNIX system invoke command is the core of the "sink" operating

Implement an embedded operating system that can't do anything 1. First determine the CPU. Here we use embedded CPU for simplicity, such as the arm series. The reason why we use a short Instruction Set)The convenience of a type of CPU is that there is no distinction between the real mode and the protection mode, and linear unified addressing is adopted, that is, the segment is not requiredPage-based memory

waits for your input to be read.C ShellBill Joy developed the C shell at the University of California in Berkeley in the early the 1980s. It is primarily intended to make it easier for users to use interactive features and to turn the grammatical structure of the ALGOL style into a C language style. It adds features such as command history, aliases, file name substitution, job control, and more.Korn ShellFor a long time, there were only two types of

monitoring or affecting processes running in other regions. For processes running in non-global regions, they cannot be viewed or affected even if they have super user permissions. The region also provides an abstraction layer to separate the physical properties of the application and the computer on which the application is deployed, such as the physical device path and Network Interface Name. Virtual Private server (VPs) [5] technology divides the
