6.4 Draw diagrams showing a conceptual view and a process view of the architectures of the following systems: Answer:
A ticket machine used by passengers at a railway station:
A computer-controlled video conferencing system that allows video, audio, and computer data to be visible to several participants at the same time:
A robot floor-cleaner that is intended to clean relatively clear spaces such as corridors. The cleaner must be able to sense walls and other obstructions:

6.2 You have been asked to prepare and deliver a presentation to a non-technical manager to justify the hiring of a system architect for a new protect. Write a list of bullet points setting out the key points in your presentation naturally, you have to explain what is meant by system architecture.
Registry System which contains Information #$traction
System, Information Storage System and Information evaluation System provides the
registry function of the all system. In that, administrator can manipulate the
information about the employee or sample,
store, delete, and add. Therefore, we have Control System. The decision making
System used to decide whether a certain employee would be hired or not.
6.1 When describing a system, explain why you may have to design the system architecture before the requirements specification is complete.
The architecture may have to be designed before
specifications are written to provide a means of structuring the specification
and developing different subsystem specifications concurrently, to allow
manufacture of hardware by subcontractors and to provide a model for system
costing. You may have to design the system architecture before the requirements
specification is complete because the architecture has a significant impact on
the non-functional requirements and can also influence the functional
requirements as well. Specifically, in order to demonstrate to stakeholders
that an application will meet its performance requirements a project manager or
system architect may have to show how the architecture will aid in
accomplishing this goal. According to Sommerville the components affect the
requirements and therefore an architecture that explains the components and their
relationships may aid in the determination of the requirements. System
architecture is to be designed first before describing the system itself simply
because the architectural design serves as basis for the description. Since it
involves identifying major system components, subsystems, and their
communications, it will be easier in the description to specify which one goes
to which subsystems. When subsystems are already made, it will be easier to
determine what components are needed by hard are manufacturers. So, the
architectural design provides a model for system costing.
