DOS

Microsoft initially chose Patterson's Q-DOS " QUICK AND DISK OPERATING SYSTEM " as the basis and then expanded its functions to create MS-DOS . It mainly used computers with 8088 microprocessors provided by IBM as development platforms. It is a 16- byte single-person, single-worker operating system, which is particularly suitable for use in some simple-function devices.

Windows CE

Although Microsoft Windows has dominated the PC desktop environment, Microsoft has long coveted the embedded system. The desktop Windows system is naturally too large for embedded systems, so Microsoft launched a streamlined version of Windows CE as the main force to attack embedded systems. Currently, it is mainly used on PDAs , but like Microsoft's series of Windows systems, Windows CE also inherits the original shortcomings: consuming system resources, instability, poor efficiency, etc. There are too many problems, so the entire architecture was rewritten and Windows CE 3.0 was launched , also known as Pocket PC . After the revision, many shortcomings have indeed been improved.

Windows CE can be applied to PDA , WebPAD , Thin Client , etc. SIMPad ( owned by Siemens ) uses Windows CE as the operating system .

Palm

An embedded operating system developed by Palm Computing . Its largest application is currently in PDAs . It is the PDA operating system with the highest market share . The Palm operating system architecture is very simple. Because it omits many functions, such as memory management, multi-tasking, etc., Palm can consume very little system resources and has low hardware requirements. The overall power consumption can be compressed to a very low level. Therefore, PDAs using the Palm operating system have the advantage of long standby time.

EPOC

Developed by Psion , a major British handheld device manufacturer , it is often used in situations where PDAs and mobile phones are combined. The most famous example is the Nokia 9110 series of mobile phones, which use the EPOC system.
