What Does Embedded Operating System Mean?
An embedded operating system is a type of operating system that is embedded and specifically configured for a certain hardware configuration. Hardware that uses embedded operating systems is designed to be lightweight and compact, forsaking many other functions found in non-embedded computer systems in exchange for efficiency at resource usage. This means that they are made to do specific tasks and do them efficiently.
Techopedia Explains Embedded Operating System
Embedded operating systems are usually used for hardware that have very little computing power, little RAM/ROM and a slow CPU, so they tend to be very specific in their applications and scope. They are usually made using assembly language in order to really take advantage of the limited computing resources, since it is the closest to machine language and is able to squeeze every drop of computing power available. This means that the OS is optimized for whatever hardware it was developed for and will not be compatible with other hardware systems with different configurations.
