Explanation:
In information technology, architecture plays a major role in the aspects of business modernization, IT transformation, software development, as well as other major initiatives within the enterprise. IT architecture is used to implement an efficient, flexible, and high quality technology solution for a business problem, and is classified into three different categories: enterprise architecture, solution architecture and system architecture. Each of these classifications varies in their implementation and design, depending on the contextual business scope, organization structure, and corporate culture.
Architecture Level
Architecture level represents the scope boundary and granularity of details the architectural activity should take, based on organization hierarchy and communication audience.
- Enterprise Architecture (Company level) aligns technological strategies and execution plans with business visions and objectives by providing architectural oversight and guidance. Enterprise architecture also drives consolidation, reuse, and economy of scale by addressing company-wide goals in a holistic way across all IT projects.
-
Solution Architecture (Department level) models a solution vision that defines the IT systems, business processes and reusable services for a specific business unit, spanning across business and technology architectures.
-
System Architecture (Team level) defines the structure of an information system in terms of various subsystem components and their relationships with internal and external systems. System architecture focuses on application, data, and technology, and is called software architecture in some organizations.
Before making decision regarding system architecture the designer must consider the following points:
- Corporate organization and culture: System architecture must study day-to-day functions of business and users in order to understand corporate organization and culture. This will help in focusing on operational feasibility which will help in deciding other checklist items.
- Enterprise resource planning (ERP): Most of the organization use ERP software these days and it is important for the analyst to understand the compatibility of the ERP which is used to the proposed system.
- Total cost of ownership (TCO): System analyst must try to get solutions of different questions which helps in finding initial cost and cost which may add up during the development, which is total cost of ownership. This is most important at this will determine total cost and budget of system.
- Scalability: Determining system ability to expand or downsize according to business requirements.
- Security: What security system and policy needs to be implemented.
Answer:
Yes it is possible for the following cases:-
- When the queue is full.
- When the queue is empty.
Explanation:
When the queue is full the the front and the rear references in the circular array implementation are equal because after inserting an element in the queue we increase the rear pointer.So when inserting the last element the rear pointer will be increased and it will become equal to front pointer.
When the queue is empty the front and rear pointer are equal.We remove an element from queue by deleting the element at front pointer decreasing the front pointer when there is only one element and we are deleting that element front and rear pointer will become equal after deleting that element.
