1. 电脑:
计算机是硬件和软件资源的组合,它们集成在一起并为用户提供各种功能。
2. 嵌入式设备:
嵌入式设备是集成系统的一部分,由计算机硬件和软件组合而成,具有特定函数,无需人工干预即可运行。
计算机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. |
