Question 1
How is data organized in a relational database?
Correct Answer:
Tables with rows and columns.
Explanation:
In a relational database, data is organized into tables of rows and columns. Each table represents a set of records that share the same structure: each row is a single record, and each column holds a specific attribute with a defined data type. The power of this arrangement comes from the ability to relate data across tables using keys—a primary key uniquely identifies a row in its table, and foreign keys link to those primary keys in other tables to establish relationships. This tabular layout supports powerful querying (via SQL), data integrity, and normalization to reduce redundancy. Other data models use different structures: graphs store data as nodes and edges to emphasize relationships; document stores keep semi-structured documents in collections; key-value stores map keys directly to values. The described tables-with-rows-and-columns layout is the distinctive setup of the relational model.
Question 2
Secret information is best described as which of the following?
Correct Answer:
Info that needs to be kept private
Explanation:
Secret information is about keeping data private so that only those who should know it can see it. The best description is information that needs to be kept private, because secrecy focuses on restricting access to protect sensitive details like passwords or personal records. Information that authorized people can access describes who is allowed to see it, not whether it should be private at all. Widely public data is the opposite of secret, and storage medium (info stored on disk) says nothing about whether the information is private.
Question 3
What format do conditional statements follow?
Correct Answer:
If this specific thing happens, then this will occur
Explanation:
Conditional statements follow an if-then structure: a condition is checked, and if it occurs, a specific action follows. This matches the format described as “If this specific thing happens, then this will occur.” The other phrases describe loops or one-time setup rather than a direct conditional trigger: doing something while a condition is true is a loop, iterating over items is also a loop, and doing something once at the start is initialization. So the best description is the if-then pattern.
Question 4
What is a key difference among the IaaS, PaaS, and SaaS cloud service models?
Correct Answer:
IaaS provides virtualized hardware; PaaS provides a platform for deploying apps; SaaS delivers software over the Internet.
Explanation:
The main idea here is how responsibility and what's being provided change across the three cloud service models. In IaaS you’re renting virtualized hardware—compute, storage, and networking. The provider handles the physical infrastructure and the virtualization layer, while you install and manage the operating system, runtimes, and applications. In PaaS you’re given a platform with built-in runtime and development tools; the provider takes care of the OS, middleware, and underlying infrastructure, and you focus on building and deploying your apps. In SaaS you’re using ready-made software delivered over the Internet; the provider handles everything from infrastructure to the application itself, and you simply use the software. That’s why the best description is: IaaS provides virtualized hardware, PaaS provides a platform for deploying apps, and SaaS delivers software over the Internet. The other options mix up what each model provides or who manages which parts, so they don’t fit the standard division of responsibilities.
Question 5
Big-O notation is used to express what?
Correct Answer:
Upper bound on growth of running time or space with input size.
Explanation:
Big-O notation describes how the resources an algorithm uses grow as the input size increases. It provides an upper bound on time or space in the worst case, focusing on the dominant growth rate and ignoring constants and less significant terms. This means it answers: as n gets large, how bad can the resource usage be at most, up to a constant factor? Why that makes sense: it’s about scaling, not exact measurements for a particular input. It’s not a lower bound (that would be Omega) and not an average-case figure (which depends on input distribution and gives expected behavior). It’s also not a precise running time for a specific input, but a way to compare how different algorithms grow as inputs get bigger. So the best description is that Big-O expresses an upper bound on the growth of running time or space with input size.
