An embedded system has a self-contained operating system on a "chip" thus embedded into the system and does not rely on having a hard disk with the operating system on it. Not to mention that is will be much faster because the access time of the OS on a chip.

More specifically...

An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software.

A PC is designed to be a general purpose computing environment.

Many of today's embedded systems are looking more like PCs with user interfaces, touchscreens, displays, keypads and more. Still, these are not general function systems but are designed to perform very specific functions.

An embedded system makes use of embedded hardware and embedded software to accomplish its purpose. Embedded software is generally comprised of: * Real-time operating system (RTOS) * Drivers (HW peripheral interface) * Application software

Railroad tracks vs 4 lane highway. The tracks run well, rarely have problems and are very well suited for the way they are being used. A 4 lane highway has all sorts of different vehicles traveling on it that may or may not be efficient to use on the freeway. When you want to ride the train to Chicago, use rails. When you want to get somewhere off the map, use the freeway.

An embedded system is designed to be run on very limited resources in a compact package. Examples of this are mobile devices we use every day (smartphones and tablets). In the case of DIY projects, the most popular name comes to mind: the Raspberry Pi.

Embedded systems are more limited in hardware and/or software functionality than

a personal computer (PC). This holds true for a significant subset of the embedded

systems family of computer systems. In terms of hardware limitations, this can

mean limitations in processing performance, power consumption, memory, hardware

functionality, and so forth. In software, this typically means limitations relative to a

PC-fewer applications, scaled-down applications, no operating system (OS) or a

limited OS, or less abstraction-level code. However, this definition is only partially

true today as boards and software typically found in PCs of past and present have

been repackaged into more complex embedded system designs.

• An embedded system is designed to perform a dedicated function. Most embedded

devices are primarily designed for one specific function. However, we now see

devices such as personal data assistant (PDA)/cell phone hybrids, which are embedded

systems designed to be able to do a variety of primary functions. Also, the latest

digital TVs include interactive applications that perform a wide variety of general

functions unrelated to the "TV" function but just as important, such as e-mail, web

browsing, and games.

• An embedded system is a computer system with higher quality and reliability requirements

than other types of computer systems. Some families of embedded devices

have a very high threshold of quality and reliability requirements. For example, if a

car's engine controller crashes while driving on a busy freeway or a critical medical

device malfunctions during surgery, very serious problems result. However, there are

also embedded devices, such as TVs, games, and cell phones, in which a malfunction

is an inconvenience but not usually a life-threatening situation.

• Some devices that are called embedded systems, such as PDAs or web pads, are not

really embedded systems. There is some discussion as to whether or not computer

systems that meet some, but not all of the traditional embedded system definitions are

actually embedded systems or something else. Some feel that the designation of these

more complex designs, such as PDAs, as embedded systems is driven by nontechnical

marketing and sales professionals, rather than engineers. In reality, embedded engineers

are divided as to whether these designs are or are not embedded systems, even

though currently these systems are often discussed as such among these same designers.

Whether or not the traditional embedded definitions should continue to evolve, or

a new field of computer systems be designated to include these more complex systems

will ultimately be determined by others in the industry. For now, since there is no new

industry-supported field of computer systems designated for designs that fall in between

the traditional embedded system and the general-purpose PC systems, this book

supports the evolutionary view of embedded systems that encompasses these types of

computer system designs.

While embedded systems and embedded software are not new, the fast rise of the internet of Things has lately brought them to the forefront.

Embedded system

An embedded system is a computer system that consists of computer memory, input/output peripheral devices, and a computer CPU. It is distinguished by its greater electrical and mechanical systems. Mechanical pieces and electronic or electrical hardware are embedded as part of a full device.

Ex: washing machines and microwaves, because they do not require a computer system to operate.

Embedded software

These programming applications are modified projects that administer specific undertakings of non-PC gadgets, either as a component of a central processor or as a feature of another application that sits on top of the chip. Unlike PC programs, which may be run on a wide range of computer systems and customized to give varying levels of capability, embedded software has set hardware requirements and capabilities.

Ex: Vehicle connectivity software.

Connected vehicles are a new technology that must meet particular quality and safety criteria.

Difference Between Embedded System And Embedded Software

Embedded software is a program that runs on an embedded device that incorporates a physical system. The physical devices are managed by software. Embedded software has established hardware requirements and capabilities that prevent third-party integration.

Embedded systems consist of both equipment and programming. A software engineer is responsible for the proper operation of the hardware during the embedded system design phase.

A computer is an independent system. I does not depend on any other system to work but an embedded system needs another system to work, so it can be called as a dependent system.
