| Hardware serve as the delivery system for software solutions. The hardware of a computer is infrequently changed, in comparison with software and data, which are “soft” in the sense that they are readily created, modified, or erased on the comput | To perform the specific task you need to complete. Software is generally not needed to for the hardware to perform its basic level tasks such as turning on and reponding to input. |
| Hardware stays at steady reliability level in useful life. | Software needs constant testing after upgrades. |
| Hardware failure is random. Hardware does have increasing failure at the last stage. | Software failure is systematic. Software does not have an increasing failure rate. |
| Hardware faults is physical. | Software faults are not. |
| Hardware wears out over time. | Software does not wear out over time. |
| It is physical in nature | It is logical in nature |
| Devices required to store and execute (or run) the software. | Collection of instructions that enables a user to interact with the computer. Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system (hardware). |
