硬件和软件之间的区别：
| Hardware | Software |
|---|---|
| Hardware is a physical parts computer that cause processing of data. | Software is a set of instruction that tells a computer exactly what to do. |
| It is manufactured. | It is developed and engineered. |
| Hardware can not perform any task without software. | software can not be executed without hardware. |
| As Hardware are physical electronic devices, we can see and touch hardware. | We can see and also use the software but can’t actually touch them. |
| It has four main categories: input device, output devices, storage, and internal components. | It is mainly divided into System software, Programming software and Application software. |
| Hardware is not affected by computer viruses. | Software is affected by computer viruses. |
| It can not be transferred from one place to another electrically through network. | But, it can be transferred. |
| If hardware is damaged, it is replaced with new one. | If software is damaged, its backup copy can be reinstalled. |
