Embedded software is a software application, written to control machines or devices that exist permanently in a device and giving some sort of control function or user interface. The software is commonly stored in a non-volatile memory, for example, ROM or flash memory.
An embedded system is a combination of the computer hardware and software accomplished with additional mechanical or electronic parts designed to perform a specific function. Embedded programming needs to cover all required device drivers at manufacturing time, and the device drivers are composed for the particular hardware.

- It is designed to do some particular task.
- Embedded systems are not always standalone devices.
- The program instructions written for embedded systems are referred to as firmware and are stored in ROM or flash memory chips.
