先决条件 – 了解硬件和软件
1. 计算机硬件工程师：
计算机硬件工程师研究、开发和测试硬件或计算机设备/组件。他们在实验室工作并开发新的硬件组件。他们解决硬件问题。他们对计算机的物理组件有广泛的了解，例如电路板、处理器、芯片和其他电子组件。他们通常在实验室工作。
惠普、三星、英特尔、AMD、IBM、东芝、索尼等公司聘请计算机硬件工程师进行硬件产品开发。
2. 计算机软件工程师：
计算机软件工程师设计、开发、测试软件，维护计算机网络和程序。他们只是在计算机上工作并通过编写程序来执行任务。他们通过为此提供任何软件解决方案来解决现实生活中的复杂问题。他们在设计架构、使用编程语言编写代码、执行测试和部署产品方面拥有广泛的知识。他们通常在办公室工作。
Apple、eBay、Facebook、Google、IBM、Infosys、TCS、Wipro 等公司聘请计算机软件工程师进行软件产品开发。
计算机硬件工程师和计算机软件工程师的区别：
| S.No. | COMPUTER HARDWARE ENGINEER | COMPUTER SOFTWARE ENGINEER |
|---|---|---|
| 01. | Computer hardware engineers research, develop and test hardware or computer equipment/components. | Computer software engineers design, develop, test software, maintains computer network and programs. |
| 02. | Hardware engineers need electrical and computer engineering degree. | Software engineers need software engineering or computer science degree. |
| 03. | Computer hardware engineers troubleshoots hardware problems. | Computer software engineers solves complex problems of real life by bringing any software solution for that. |
| 04. | Computer hardware engineers works in lab and develop new hardware components. | Computer software engineers just with a computer performs their work by writing programs. |
