Symbian features pre-emptive multitasking and memory protection, like other operating systems (especially those created for use on desktop computers). EPOC's approach to multitasking was inspired by VMS and is based on asynchronous server-based events.
The Symbian OS was one of the pioneers of smartphone technology. It brought forth several features that made mobile phones much more capable. From the OS’s launch till its discontinuation, here’s everything you need to know about the Symbian operating system.
15 cze 2024 · Symbian OS was developed specifically to run on the smartphone platform. The heritage of Symbian OS begins with some of the first handheld devices. The operating system began its existence in 1988 as SIBO (an acronym for '16-bit organizer').
Much of the functionality described in this chapter is transparent from a typical Symbian OS application programming view; however, understanding the architectural details of an operating system can be useful in developing software for it — especially for programming on highly reliable, limited-resource devices such as smartphones.
Communication and Multimedia. Pluggable messaging architecture. New message types can be invented and dynamically loaded by the messaging server New transport methods can be introduced by implementing new object and loading into the kernel. Multimedia devices and content are handled by special servers.
3 lut 2024 · Linux is typically considered a monolithic-kernel operating system. Most system functions are implemented in 'kernel space' (by the code and within the memory of the kernel). Symbian OS is implemented via a microkernel. The example in Section 2.1 of defining and opening a communication device serves well here.
The information presented here is generic for all platforms based on Symbian OS. I begin the chapter with an overview of the use of C++ in Symbian OS, followed by a look at the basic data types, the key types of classes you'll use and create, and the Symbian OS naming conventions.
