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:
A. Define boundaries
C. Deny access
D. Delay access
Explanation:
A barrier is a material or structure used to prevent or block access. Barriers can either be natural or structural and are used for many purposes usually for security reasons. The following are functions of barriers either natural or structural:
- Define areas of boundaries
- Delay or slow access. Example is the use of speed bumps to slow down vehicles.
- Provide access to entrances such as the use of gates
- Deny access to unauthorized personnel and allowing authorized personnel.
