Question

19 according to lecture, which cloud model includes ondemand software access? paas iaas staas saas 20 according to lecture, responsible recycling policies include: selling used hardware immediately only disposing of computers in regular trash keeping old computers indefinitely ensuring old computers are ep compliant 21 according to lecture, telecommuting helps reduce: equipment maintenance productivity employee collaboration carbon footprint 22 according to lecture, html and http were created by: sir tim berners-lee google engineers amazon web services microsoft developers

Explanation:

• Question 19: SaaS (Software - as - a - Service) provides on - demand software access. PaaS (Platform - as - a - Service) offers a platform for development, IaaS (Infrastructure - as - a - Service) provides infrastructure like servers, and StaaS is not a common major cloud model in this context.
• Question 20: Ensuring old computers are EP (Environmental Protection) compliant is a responsible recycling policy. Selling used hardware immediately may not be environmentally sound if not done properly, only disposing in regular trash is bad for the environment, and keeping old computers indefinitely is not a recycling policy.
• Question 21: Telecommuting helps reduce the carbon footprint as it reduces the need for commuting (which involves fuel consumption). It does not reduce productivity (in fact, it can sometimes increase it with flexible work hours), and it can enhance employee collaboration through digital tools. Equipment maintenance is not directly reduced by telecommuting.
• Question 22: Sir Tim Berners - Lee created HTML (HyperText Markup Language) and HTTP (HyperText Transfer Protocol). Google engineers, Amazon Web Services, and Microsoft developers were not the creators of these fundamental web technologies.

Answer:

1. SaaS
2. Ensuring old computers are EP compliant
3. Carbon footprint
4. Sir Tim Berners - Lee
