The purpose of the requirements definition phase is to produce a clear, complete, consistent, and testable  （1）  of the technical requirements for the software product.
During the requirements definition phase, the requirements definition team uses an iterative process to expand a broad statement of the system requirements into a complete and detailed specification of each function that the software must perform and each  （2）  that it must meet.The starting point is usually a set of high-level requirements from the  （3）  that describe the project or problem.
In either case, the requirements definition team formulates an overall concept for the system and then defines  （4）  showing how the system will be operated, publishes the system and operations concept document, and conducts a system concept review（SCR）.
Following the SCR, the team derives  （5）  requirements for the system from the high level requirements and the system and operations concept. Using structured or object-oriented analysis, the team specifies the software functions and algorithms needed to satisfy each detailed requirement.

Serialization delay and  （1）  delay are the two components of network delay that are improved by increasing bandwidth. Serialization delay, i.e. the amount of time it takes to put the  （2）  on the wire, and queuing delay (depth of the queue) are improved by increasing the  （3）  from a 128kbps circuit to a T1. However, three other components of delay, routing/switching delay, distance delay, and protocol delay are components that can not be positively affected by an  （4）  in bandwidth. If the circuits are not over-utilized, then increasing the bandwidth to improve the  （5）  of the application will only result in an increased bandwidth with no positive effects on performance.
