电脑与嵌入式系统的区别

1.电脑：
计算机是硬件和软件资源的组合，它们可以集成在一起并向用户提供各种功能。

2.嵌入式设备：
嵌入式设备是集成系统的一部分，该集成系统形成为具有特定函数的计算机硬件和软件的组合，并且无需人工干预即可运行。

电脑与嵌入式系统的区别：

S. No.	Category	Computer	Embedded device
1.	Description	A computer is a combination of hardware and software resources which integrate together and provides various functionalities to the user.	An embedded device is a part of an integrated system which is formed as an combination of computer hardware and software for a specific function and which can operate without human interaction.
2.	Human Interaction	A computer needs Human Interaction to perform tasks.	Embedded device does not need Human Interaction to perform tasks.
3.	Types based on architecture	Analog computer, Digital computer, Hybrid computer, Harvard architecture, Von Neumann architecture, Reduced instruction set computer	Small Scale Embedded System, Medium Scale Embedded Systems, Sophisticated or Complex Embedded Systems
4.	Parts	It has 2 parts: Hardware and Software.	It has 3 parts: Hardware, Firmware and Software.
5.	Tasks	It can perform many tasks.	It performs limited tasks.
6.	Cost to user	The user has to pay more for a computer.	The user incurs lesser cost for an embedded system.
7.	Peripherals	Computers have peripherals such as keyboard and mouse, display, printer, Hard disk drives, floppy disk drives, optical disc drives etc.	Embedded Devices have peripherals such as Serial Communication Interfaces (SCI), Synchronous Serial Communication Interface, Universal Serial Bus (USB), Multi Media Cards (SD cards, Compact Flash) etc.
8.	Purpose	Computers can be reprogrammed to for a new purpose.	Embedded Devices are made only for a specific set of purposes.
9.	Power Consumption	Computer needs more operational power than Embedded Devices.	Embedded Device needs lesser operational power than a Computer.
10.	Complexity	Computers are more complex devices than Embedded Devices.	Embedded Devices are less complex devices than Computers.
11.	Need of another device	Computers may be installed in other devices but are self-sufficient to exist.	Embedded Devices only exist inside other Systems.
12.	Usage Difficulty	Computers are more Difficult when used, compared to an Embedded System.	Embedded are easier to use than Computers.
13.	User Interfaces	It requires more user interface than Embedded Devices.	It requires lesser to no user interface than Computers.
14.	Time Specificity	Computers are not time specific. They may need to perform tasks which are not time bound and take days to perform as well.	Embedded Devices are time specific. The tasks assigned to them need to be performed within a specific time frame.
15.	Size	Computers are usually bigger in size with larger hardware and input output devices attached to it.	Embedded Devices are smaller in size than Computers, with limited hardware.
16.	Developed in	1965 A.D.	1833 A.D.
17.	Developer	Charles Stark Draper	Charles Babbage
18.	Memory Requirement	Computers have larger memory requirement due to a lot of storage of data.	Embedded Devices need lesser Memory.
