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

 A relation is a type of association that describes how two or more entities are related to each other. A relation can have different properties, such as cardinality, optionality, and directionality, that specify the nature and constraints of the association. A relation can also have attributes that store information about the association. For example, a relation between Employee and Project entities can have an attribute called Role that indicates the role of each employee in each project. A relation can be represented by a line connecting the entities in an entity-relationship diagram (ERD). References: Association and Associative entity - IBM, When to use Associative entities? - Stack Overflow, [Entity-Relationship Model - Tutorialspoint].
