Embedded and General-Purpose Computer Systems
Introduction
If you struggle to differentiate between Embedded and General-Purpose Computer Systems, then you are at the right place. The difference between a computer and an embedded system is that a computer is a general-purpose electronic device used to carry out a variety of computing tasks. Whereas an embedded system is a specialized computer designed to carry out one or more particular duties.
Read on to know the difference between general purpose computer and embedded system.
What is a Computer?
An electronic device called a computer is made to carry out a variety of computing functions. Thus, a computer can be thought of as a general-purpose electrical device that can be used for a range of tasks, such as simple word processing and web browsing as well as deep data analysis and scientific simulations.
The programming of a computer makes it possible for it to use application software to carry out various tasks. Different software programs are created for computers to fulfil the needs of various users and sectors.
Desktops, laptops, tablets, cellphones, and other similar devices are typical instances of computers. These computing devices can be used to create documents, browse the web, edit photos and videos, play games, and many other things.
An embedded testing course will help you know the basics of computer systems as well.
What Are General-Purpose Systems?
A computer that can be designed to carry out a variety of activities is known as a general-purpose system. General-purpose computers are made to meet a wide range of purposes by allowing users or devices to interact with them in a variety of ways.
A general-purpose system may execute a wide variety of tasks thanks to its capacity to run various software applications. A system’s function can be changed by adding, updating, or removing software with relative ease.
A general-purpose system often has a large selection of inputs and outputs that can be attached to it. It is different from embedded systems programming in many ways.
What Are Embedded Systems?
Computer systems that perform a limited set of tasks are known as embedded systems. Manufacturers will focus on the specific tasks that an embedded system must complete when creating it. They will tweak the system until it completes each of these duties with exceptional efficiency. You may get more clarity through an embedded systems course.
Firmware, a kind of software used for this purpose, is used to create embedded systems to have very close control over the hardware. Because it offers direct control over particular hardware components, assembly language is used to create firmware.
The microcontroller seen in recent embedded systems has a fixed amount of RAM and ROM plus a central processing unit (CPU) to process data. Go for an embedded course to know about the workflow of this system.
Difference Between General-Purpose System And Embedded System
Read the below comparison to easily differentiate between general purpose and embedded system based on various criteria.
General Purpose Computer
Design: Its primary processing component is a CPU.
Basic: A computer is a multipurpose electrical tool used to carry out various activities.
Memory: It has a substantial amount of RAM and cache semiconductor memories. It also includes auxiliary storage, such as hard disks, etc.
Operation System: As a rule, the operating system and other software for general-purpose computers are more complex and take up more memory.
System Hardware: A CPU, storage device, and I/O devices are the basic components of a computer.
Cost: When compared to embedded systems, it is more expensive.
Storage Capacity: Computers have large amounts of memory or storage space for storing data and information.
Embedded Systems
Design: A microcontroller serves as the primary processing component for the majority of its design.
Basic: A computer system that has been designed to carry out one or more defined tasks is known as an embedded system.
Memory: It employs semiconductor memories but doesn’t need additional memory sources like CDs or hard drives. It has a type of memory called flash memory.
Operation System: The operating system, which is mostly an RTOS (Real Time Operating System), and other software take up little memory.
System Hardware: Microcontrollers are used in embedded systems because they combine a CPU, memory unit, and I/O interface on a single IC chip.
Cost: Compared to a computer, it is less expensive.
Storage Capacity: Compared to computers, embedded devices have a smaller memory capacity.

Conclusion
This universal Approach of input, storage, processing, and output serves as the foundation for all computer systems. Computer systems can be built and used in an array of ways, but there are several key distinctions. General-purpose and embedded systems are the two broad categories into which computer systems can be divided.
