Hardware:
-physical parts of a computer that cause processing of data
-can be connected (physically) & can touch
- Hardware wares out during/over time
-Hardware failure is random
Software:
-A set of construction that tells a computer exactly what to do
-software is logical in nature
- dose not have an increasing failure rate
Similarities
- Behavior; Users interact with the products in various ways
- Products produce outputs and given inputs
-they have functional (user facing) and non functional (non user facing) requirements
-They are both complex (any representation of product specifications lead to a main structure)
Differences
- Software is easier to change then hardware
- Software testing is done by specialized quality assurance (QA) engineers, while hardware is done by engineers who are creating the product
-Hardware must be designed and tested to work over a range of time and environmental conditions, which is not the case for software
- Hardware designs are constrained by the need to incorporate standard parts

Answer: measures how quickly a system performs a process or transaction
Explanation:
Computer performance refers to how well a given computer system performs, which is estimated by its accuracy, efficiency and speed when completing a process or transaction.
A computer performance evaluation will assess a system's resources and outputs to make sure that it´s performing in the best possible way.
Some parameters of performance are latency, speed, throughput, and bandwidth.
