SDLC PRactice Quiz

A model that is the demo implementation of the system

• prototype

• waterfall

• incremental

• agile

Implementing the solution is the stage where:

• coding in a programming language takes place.
• testing of the solution takes place.
• determining the requirements takes place.
• modification of the solution takes place.

What happens in the design phase?

• The code is produced
• Making changes when the sotware has been created
• Planning the solution, look and feel of the software interface
• Ensuring the requirements are understood

Define an algorithm.

• A set of instructions used to solve a problem.
• A set of instructions for a computer to follow
• A set of instructions for a human to follow
• A set of instructions used to create a problem.

State key qualities or considerations good algorithms should make.

• Inputs must be clearly defined - what is valid and what is invalid?
• Must always produce a valid output for any defined input.
• Must be able to deal with invalid inputs.
• Must always reach a stopping condition
• Must be well-documented for reference.
