Introduction to Embedded System
In today’s post, we are going to learn and discuss what are the Advantages and Disadvantages of Embedded Systems | Benefits and Drawbacks of Embedded Systems with illustrative images, meaning, definition, and examples.
The Embedded system is also called an integrated system.
An Embedded system is a combination of both hardware and software.
These devices which are equipped with embedded systems are smart and efficient machines
The devices may be a smartphone, smartwatches, smart home devices, medical equipment, security alarms, products, etc.
The advancement in machine learning and artificial intelligence is playing an important role in enhancing and updating the performance of embedded system-enabled devices.
The embedded systems are also known as Firmware.
What is Embedded System and its Type?
As discussed before the embedded system is a combination of both software and hardware which are embedded into the system to perform a specific and special task.
The embedded system is a computer hardware system where software is incorporated into them.
They can be an independent or standalone system or a part of a huge system.
The Embedded system is associated with a microcontroller and microprocessor which are designed and developed for performing, implementing, and executing specific tasks.
The major benefit of an embedded system is that it can be designed, developed, and programmed to derive desired results and outputs according to the needs and requirements.
The Embedded systems are also called “Integrated Systems”.
These systems are used in our daily and routine life like smartphones, washing machines, DVD players, printers, modern instruments, etc.
Advantages and Disadvantages of Embedded Systems
Benefits and Advantages of Embedded Systems
- They are very compact in size, with high speed.
- Embedded Systems are very reliable.
- They consume less power and electricity, and they also perform task and operations assigned to them with great accuracy.
- They are built to perform special task and operations given to them.
- They can be customized for producing more enhanced results.
- They are comparatively cheaper.
- They concentrate on single operation at single time therefore they can process at very high speed with quality outputs.
- The Embedded system can be easily incorporated with small and large devices to perform dedicated jobs.
- Due to their silent features they are all used in modern devices and equipment’s for improved performance.
Drawbacks and Disadvantages of Embedded Systems in Points
- The Embedded Systems are very tedious and difficult to upgrade and update.
- Requires lot of time and energy to maintain these systems.
- Embedded system errors are very difficult to rectify and resolve.
- They are very hard to backup.
- Huge modification cannot be implemented on these systems.
- Embedded system performs a specific operation assign to them and does the same task repeatedly.
- They are not associated microprocessor or microcontroller for processing.
- If system get damage or corrupt they are completely changed and removed.
Characteristics of Embedded System
- Embedded systems are embedded with hardware and software.
- They are built to produce and implement certain and specific task or Jobs.
- They are incorporated with microprocessor or microcontroller.
- Can deliver tasks and jobs on particular time without any human intervention.
- They can work with real time.
- They are compact in size and therefore easy to use as their user interface is quite simple to interact.
- They concentrate on single task and operation at given time.
Examples of Embedded System
- Mobile Phones
- Industrial Equipment’s
- Medical Instruments
- Electronic Equipment’s and Devices like washing machines and Owen.
- Security Peripherals and devices
- Fire alarms.

Types of Embedded Systems
The embedded systems are divided into four types with respect to their performance and requirements
- Stand Alone Embedded Systems
- Real Time Embedded Systems
- Networked Embedded Systems
- Mobile Embedded Systems
Stand-Alone Embedded System
The Stand-Alone Embedded systems are capable of performing tasks and operations on their own they receive analog signals from input devices and produce digital signals after processing.
They are well equipped to handle, calculate and transfer data and information.
Examples of Embedded System are DVD Players, Digital Cameras, Washing machines, and Digital Owen.
Real-Time Embedded Systems
The real-time embedded systems are used for performing specific and special tasks in a given time.
These systems follow every instruction and process them accordingly in that specific time.
These systems are designed, developed, and programmed to produce output in real-time with great accuracy and strict deadlines.
The real-time embedded systems can be divided into two types.
- Soft real time embedded system
- Hard real time embedded system
Networked Embedded Systems
The Network Embedded Systems are connected with the networks like LAN, WAN and therefore called embedded system applications.
Mobile Embedded Systems
The Mobile Embedded System is used in Portable Embedded Devices like mobile phones, digital cameras, MP3 Player, etc.
