Answer 1

1. Answer: application layer, presentation layer, and data layer

Explanation:

The first tier in the three-tier architecture is a presentation layer that provides visual content to the end-user. Second-tier runs the software for business processes and it is the application layer. Third-tier includes the data layer for data storage and accessing the data.

2.Answer: False

Explanation:

A company that utilizes software-as-a-service (SaaS) needs not physically install the ES at their facility because the software is hosted in the data center of a service provider and customers take the service through the internet without physical installation.

3.Answer: analyze

Explanation:

The five basic components of supply chain management include plan, source, make, deliver and return. A company should have a good plan on how to manage the resources and choose the suppliers carefully as part of sourcing. Make is the step where manufacturing takes place and 'deliver' refers to logistics. Return involves helping customers with problems in the product by receiving defective products. Analyze is not a basic component of supply chain management.
