Answer: D
Explanation:
"During the "requirements and analysis" phase of a software development project, developers create a detailed plan that specifically defines how each of the needed features will be implemented."
The requirements gathering and analysis phase is a crucial step in the software development process. It involves collecting detailed information about each requirement and understanding its purpose. The focus of this phase is to determine the best way to fulfill each requirement and to plan for testing.
During this phase, input from testers is also valuable as they contribute to the analysis of the requirements. Additionally, this step includes a key decision-making aspect, the buy vs build decision. It is important to evaluate whether it is more cost-effective to purchase a third-party product instead of building one from scratch.

why is packet switching in the internet analogous to driving from one city to another and asking directions along the way?
The packet switch determines the outgoing link based on the packet's destination IP address.
Asking which route to take is comparable to a packet asking, given its destination address, which outgoing link it should be forwarded on. In digital telecommunications networks, such as computer networks, packet switching is used to minimize transmission latency—the amount of time it takes for data to move across a network—increase communication reliability, and make the best use of the channel capacity that is available. Small data packets are sent between different networks using packet switching. These data "packets" or "chunks" enable quicker, more effective data transport. A file is frequently sent across a network in smaller data packets when a user does so.
