Obtaining the data of a video file from a flash drive is an example of a(n) _________ operation.
a)retrieval. b)comparison. c)storage. d)exponentiation.
Answer:
a)retrieval.
Explanation:
A retrieval operation simply means obtaining data or information that is stored in a system.
Therefore, getting the data of a video file from a flash drive is a retrieval operation because it brings the video file from the storage device.
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?)
