Question 1
Which type of memory describes a special type of rewritable memory that is compact and portable?
Correct Answer: C
Rationale: Flash memory is a type of non-volatile memory that can be rewritten, is compact, and is highly portable, making it ideal for devices like USB drives, SD cards, and solid-state drives. Random access memory (RAM) is volatile and not portable; cache is a small, fast memory used for temporary storage; and read-only memory (ROM) is not rewritable.

Question 2
An organization wants to use an application software that increases the cooperation and joint productivity of small teams of employees. Which application software will serve this need?
Correct Answer: C
Rationale: Collaborative systems, such as tools like Microsoft Teams, Slack, or Trello, are designed to enhance communication, task sharing, and productivity among team members. Personnel systems focus on HR functions, data management handles data storage and retrieval, and program management oversees multiple projects, none of which prioritize team collaboration.

Question 3
Which type of software saves information if there is a system error?
Correct Answer: D
Rationale: Crash-proof software is specifically designed to save data during system failures, ensuring data integrity and recovery. Disk optimization improves performance, uninstallers remove software, and data encryption protects data but does not address system errors.

Question 4
Which minor component holds non-volatile memory?
Correct Answer: D
Rationale: Read-only memory (ROM) is non-volatile, meaning it retains data without power, unlike RAM, which is volatile. The ALU performs computations and does not store data, while SSDs are storage devices, not minor components.

Question 5
Which type of logical data structure uses graphics to illustrate relationships among data elements?
Correct Answer: D
Rationale: Data models use graphical representations, such as entity-relationship diagrams, to illustrate relationships among data elements. Structured query language (SQL) is a query language, integration connects systems, and the relational database model defines data organization but is not inherently graphical.
