Answers

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

(Hope this helps?)

Answer:

DIFFERENCES BETWEEN HARDWARE AND SOFTWARE

Hardware

Hardware is Tangible.Hardware cannot be infected by viruses.Hardware has monitors, hard drives, USB and etc.If hardware gets damaged it can be replaced.They are mostly made using electronic materials.

Software

Software is non-tangible.Software can be infected by viruses.It consists of applications and system software.It is usually developed using a programming language.It can be affected by bugs.
