- C. Cloud Computing
45. Virtual memory is used to:
Virtual memory is a memory management technique that allows a computer to compensate for physical memory shortages by temporarily transferring data from RAM to disk storage, effectively extending RAM.
- B. Extend RAM
46. Consider the table below,

ID NAME SUBJECT
F3 Mercy Chem, Bio
F4 John Math, ICT
How many records and Fields are found on the table above?
- Fields are the columns in a table. In this table, there are three fields: ID, NAME, and SUBJECT.
- Records are the rows of data in a table. In this table, there are two records: (F3, Mercy, Chem, Bio) and (F4, John, Math, ICT). Therefore, there are 3 fields and 2 records.
- C. 3 fields and 2 records
47. The Amount of time a task can delay without a delay in a project Completion date.
This definition refers to slack time (also known as float) in project management, which is the amount of time an activity can be delayed without affecting the project's overall
