 In a database, each row represents a single, implicitly structured data item in a table. A row is also called a record or a tuple. A record contains multiple fields, each one defined in a different column. A field is the intersection of a row and a column, and it holds a single value. A column is also called an attribute or a field name, and it defines the type and constraints of the data in that column. References:

Global information systems are information systems that span multiple countries, cultures, and organizations. They enable the sharing of data, knowledge, and resources across borders and regions. However, limited access to high speed internet may impede the development of global information systems, as it affects the quality, speed, reliability, and security of communication and collaboration. According to the International Telecommunication Union (ITU), in 2020, only 51.4% of the world’s population had access to the internet, and only 19.1% had fixed broadband subscriptions1. This means that many people and regions are still digitally excluded or underserved, especially in developing countries and rural areas. This digital divide may create challenges and barriers for the design, implementation, and management of global information systems, such as:

• Lack of infrastructure and resources: Developing and maintaining global information systems requires adequate and stable infrastructure and resources, such as servers, routers, cables, satellites, power supply, bandwidth, etc. However, many regions lack the necessary infrastructure and resources to support high speed internet access, or face high costs and risks of disruption or damage2. This may limit the availability, performance, and scalability of global information systems, and increase the complexity and cost of their development and maintenance.
• Lack of interoperability and standardization: Global information systems need to ensure interoperability and standardization among different systems, platforms, protocols, formats, and languages. However, limited access to high speed internet may hinder the adoption and integration of common standards and technologies, such as cloud computing, web services, APIs, etc. This may result in compatibility issues, data inconsistency, and inefficiency of global information systems, and require more effort and coordination to achieve interoperability and standardization3.
• Lack of user participation and satisfaction: Global information systems need to consider the needs, preferences, and expectations of diverse and distributed users and stakeholders. However, limited access to high speed internet may affect the userparticipation and satisfaction of global information systems, as it may reduce the usability, accessibility, and functionality of the systems, and cause delays, errors, or failures of communication and collaboration. This may lead to user frustration, dissatisfaction, and resistance, and lower the adoption and acceptance of global information systems.

Development cost is the type of cost that is considered as actual costs of analysis, design, and installation for the system. Development cost includes the expenses incurred during the planning, designing, building, testing, and deploying of a system. Development cost is usually estimated before the start of a project and is used to measure the feasibility and profitability of a system. Development cost is also used to monitor the progress and performance of a project and to control the scope and quality of a system. References: CITM Course Outline, Module 4, Corporate IT Strategy, page 9. CITM Training Course, Cost, page 14. CITM Certification Overview, Exam Information, Course Outline, Module 4.

RAM, or Random Access Memory, is the best fit for the statement because it is the main memory of the computer system and is volatile. RAM is a type of computer memory that is used to store data that is currently being used by the computer’s operating system and applications. RAM is volatile because it loses its contents when the power supply to the computer is turned off or interrupted. RAM is also faster and more expensive than other types of memory, such as ROM, PROM, or hard disk, which are non-volatile and can retain data without power. RAM isdivided into two types: static RAM (SRAM) and dynamic RAM (DRAM), which differ in their speed, power consumption, and design. References
