What is the difference between commands used in OS and RTOS?
This is not an easy question to answer because every (commercial) RTOS or OS will have a somewhat different structure and different application programming interface (API).
In general, OSes and RTOSes will function similarly in some respects. Each must abstract the processor, provide some data passing capability, allow the scheduling of operations (or tasks), manage memory, etc.
The primary difference is that an RTOS is designed for real-time, deterministic behavior. That means that the highest priority task that is ready to run gets control of the processor. All other operations must give up processor control until that task finishes and releases the processor (then the next task with the highest priority will run.) Such a deterministic environment is critical for systems that must have predictable behavior (unlike PCs).
Historically, RTOSes were intended for "deeply embedded" applications where the system had a narrow, tightly defined purpose (like an engine control system). In such a system, the developer has complete control over what software will run on the system and how the system should behave in various situations.
General purpose OSes were developed for personal computers designed to support multiple, general purpose applications. The system developer must be prepared for a wide range of diverse software to run on the system. He cannot control what will software will run or how often. A key role for the OS is to establish an environment where all of this third party software can cohabitate.
Linux and RTOS are two distinct concepts. Linux is the name given to a specific operating system. An RTOS (Real-Time Operating System) is a specially designed TYPE of Operating System. Where a 'normal' Operating Systems schedule resources/processing time to programs when they are available to the system, whereas an RTOS specializes in allowing programs to run in 'real time', meaning they are able to respond to changes (typically from an external source) as close to…
Hardcode is the code (usually written in C) that MUSH games are written in. The hardcode runs the game itself, and lets people connect, use commands like "move" and "say" and "pose", etc. Softcode is a language (written in C, as a part of the hardcode) that can be used inside the game for setting attributes, sending messages to players, and writing custom commands.
A real-time operating system (RTOS)[Generally pronounced as: Or-tos] is a multitasking operating system intended for real-time applications. Such applications include embedded systems (programmable thermostats, household appliance controllers, mobile telephones), industrial robots, spacecraft, industrial control (see SCADA), and scientific research equipment. An RTOS facilitates the creation of a real-time system, but does not guarantee the final result will be real-time; this requires correct development of the software. An RTOS does not necessarily have high throughput; rather…
What is the difference between the energy used in photosynthesis and the energy used in cellular respiration?
I think you meant msdos.sys. The commands in DOS used to move files are COPY and XCOPY. These commands will move files between drives or between folders. Most DOS commands have an online explanation if you follow the command with a /?. An example of copying is COPY filename.exe D: if you are already on the C: drive. XCOPY is more versatile with more than 20 different switches It can copy hidden and system files…
What is the difference between internal and external commands? The terms "internal and external" commands bring the Dos operating system in mind! While the terms are still used these days, I'll refer to the Dos O/S example to help you understand the concept and their difference. The Dos operating system requires a few critical files in order to work correctly, one of these is the 'command.com' file, which is a basic part of the operating…
One difference between a series and a parallel inverter is that series inverters are connected one after another. Whereas, parallel converters are only connected individually. Another difference between the two is that series inverters are used in small sub servers, whereas, parallel inverters are used in main servers.
There is no difference: these two elements are often combined. Both are used essentially for entertainment, although out of context, one could say that film can also be used for evidence, which is not necessarily true of drama. Your question is like asking about the difference between a grape and a potato -- they are both food.
