Explanation:
Systems analysis is the second step in the Systems Design Life Cycle (SDLC), which is a process for planning, creating, testing, and deploying an information system. Systems analysis involves gathering and analyzing the requirements of the system, such as the user needs, the business objectives, and the functional specifications. Systems analysis also involves modeling the system using various techniques, such as data flow diagrams, entity-relationship diagrams, and use case diagrams. Systems analysis helps to define the scope and boundaries of the system, as well as the inputs, outputs, processes, and data structures. Systems analysis is essential for ensuring that the system design meets the expectations and needs of the stakeholders.

Explanation:
A client-server environment is a type of distributed system that divides the application logic into three layers: presentation, application, and data. The presentation layer is responsible for the user interface and interaction, the application layer contains the business logic and functionality, and the data layer manages the storage and retrieval of data. Each layer can run on a different machine or server, allowing for scalability, modularity, and security1234

Explanation:
Restrictions on Internet access and efforts to censor web sites may impede the development of a global information system by limiting the availability, diversity, and quality of information that can be accessed and shared across borders. Such restrictions may also hamper the innovation, collaboration, and communication that are essential for the advancement of technology, science, and society. According to the CITM study guide, a global information system is “a system that collects, processes, stores, and disseminates information that is relevant to the needs of users in different countries” (p. 26). The benefits of a global information system include “improved decision making, enhanced coordination, increased efficiency, reduced costs, and greater customer satisfaction” (p. 26). However, these benefits can be undermined by various forms of internet censorship, such as: Manipulating search results to favor certain sources or viewpoints, or to hide or distort information that is unfavorable to the censoring authority.
Blocking access to specific sites or domains that contain information that is deemed illegal, immoral, or politically sensitive by the censoring authority.
Shutting off internet access altogether or imposing bandwidth limitations during times of crisis, protest, or conflict to prevent the dissemination of information that could challenge the status quo or mobilize opposition.
Requiring users to register or obtain licenses to access certain sites or services, or to use encryption or VPNs, which can deter or restrict internet usage and expose users to surveillance or prosecution. Monitoring, filtering, or deleting online content or communications that are considered harmful, offensive, or subversive by the censoring authority, or imposing self-censorship through legal or social pressure.
These forms of internet censorship can have negative impacts on the development of a global information system, such as:
Reducing the amount and variety of information that is available to users in different countries, which can limit their knowledge, awareness, and understanding of global issues and perspectives. Lowering the quality and reliability of information that is available to users in different countries, which can impair their ability to make informed and rational decisions, or to verify and challenge the information they receive.
Restricting the opportunities and platforms for users in different countries to exchange and share information, ideas, opinions, and feedback, which can hinder their collaboration, innovation, and creativity.
Violating the rights and freedoms of users in different countries to access and express information, which can undermine their participation, representation, and empowerment in the global society.

Explanation:
According to the Certified IT Manager (CITM) course outline, there are nine stages in a systems design life-cycle. They are: 1. Initiation, 2. Concept Development, 3. Planning, 4. Requirements Analysis, 5. Design, 6. Development, 7. Integration and Test, 8. Implementation, and 9. Operations and Maintenance. Each stage has its own objectives, deliverables, and activities that ensure a systematic and effective approach to system development.

Explanation:
Classes are a representation of some real-world thing and a number of specific instances of that thing. Classes define the common characteristics and behaviors of a group of objects, such as properties, methods, and events. Objects are individual instances of classes that can have different values for the properties and variables defined by the class. Procedures are blocks of code that perform a specific task or function. Links are connections between objects that allow communication and interaction.
