Answer:
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:
grid computing
Explanation:
<h2><u>Fill in the blanks </u></h2>
<u>grid computing</u> involves connecting geographically remote computers into a single network and combining the computational power of all computers on the network. It takes advantage of the the fact that most computers use their central processing units on average only 25 percent of the time, leaving 75 percent of their capacity available for other tasks.

Answer:
Electronic Data Interchange (EDI)
Explanation:
Electronic Data Interchange
It is the automated interchange of commercial information using a structured format. A process that allows a company to send information to another company electronically rather than on paper. Commercial entities that conduct business electronically are called business partners.
Numerous commercial documents can be exchanged using electronic data interchange, but the two most common are purchase orders and invoices. At a bottom, EDI interchanges the preparation and handling of mail associated with traditional commercial communication. However, the true power of EDI is that it standardizes the information communicated in commercial documents, which makes a "paperless" exchange possible.
Answer:
A: Affects the sequential flow of control by executing different statements based on the value of a Boolean expression
Explanation
because the real definition is Definition. A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences. For this conditional statement, P is called the hypothesis and Q is called the conclusion. Intuitively, “If P then Q” means that Q must be true whenever P is true. And A, explain that.
Answer:
The correct answer is option (D).
Explanation:
According to the scenario, the most appropriate answer is option (D) because the firewall can be defined as the software program which checks through the network for incoming and outgoing communication on predefined rules.
while the other options are wrong because of the following reasons :
- A sniffer can be defined as the program which is used to check the network traffic but it didn't work on predefined rules.
- An auditor can be defined as a program that is used to analyze the network.
- The hacker can be a person who hacks the system to gain access or gather information.
