Answer: Both Agile and waterfall model are software development models to deliver a final outcome in the form of a software product. Waterfall model is sequential process with the requirements beings rigid and defined before beginning the software development.
Agile method basically concerned with the requirements of the client. Here both testing and development is carried out at the same time.
Explanation:
More differences between the two include :
Waterfall model is easy to manage whereas in agile model as the the client requirements changes and wants more functionalities is becomes a bit more difficult to manage. the role of project manager is very crucial in waterfall model whereas the role of developers ans testers is more important in Agile model.
Software that people commonly use in the workplace to make their lives easier is called system software.
Answer:
Interference.
Explanation:
As the user is communicating with their friend through the mobile, most of their interaction is interrupted by the noise of an airplane flying at low hight. Instantly afterward, the user's mobile phone rang, disrupting the communication once more.
So, according to the following scenario both of those are examples of interference.
Answer:
Assistive technologies
Explanation:
Assistive technologies are adaptive devices and softwares that are designed to serve as aids to people with disabilities in improving their functional capabilities and making them carry out activities that are difficult to perform independently. Assistive technologies include devices and software programs that are designed for physically challenged people to help them improve their use of their computer. Examples include JAWS, Voiceover which are screen reader softwares designed for the visually impaired people.
The pseudocode to calculate the average of the test scores until the user enters a negative input serves as a prototype of the actual program
<h3>The errors in the pseudocode</h3>
The errors in the pseudocode include:
- Inclusion of unusable segments
- Incorrect variables
- Incorrect loops
<h3>The correct pseudocode</h3>
The correct pseudocode where all errors are corrected and the unusable segments are removed is as follows:
start
Declarations
num test1
num test2
num test3
num average
output "Enter score for test 1 or a negative number to quit"
input test1
while test1 >= 0
output "Enter score for test 2"
input test2
output "Enter score for test 3"
input test3
average = (test1 + test2 + test3) / 3
output "Average is ", average
output "Enter score for test 1 or a negative number to quit"
input test1
endwhile
output "End of program"
stop
