Question 1

Events are sometimes called transactions.

Accepted Answer

In certain contexts, especially in computing and business, events can be referred to as transactions when they involve a change of state or transfer of data or value.

Question 2

A function is a unit of work that must be completed as a unit or whole.

Accepted Answer

A function is a block of code designed to perform a specific task, not necessarily completed as a unit or whole. The description given is more akin to a transaction in database systems.

Question 3

Elementary processes are discrete, detailed activities or tasks required to complete the response to an event.

Accepted Answer

Elementary processes refer to the basic, individual actions or tasks that are necessary to respond to an event, often forming part of a larger process.

Question 4

Elementary processes are the overall activities to be accomplished by a system.

Accepted Answer

Elementary processes are the smallest units of work that can be independently executed and are not the overall activities of a system.

Question 5

Elementary processes are at the highest level of detail when depicted in a process model.

Accepted Answer

Elementary processes are at the lowest level of detail in a process model, representing the most basic tasks or activities.

Question 6

Elementary processes are the lowest level of detail when depicted in a process model.

Accepted Answer

Elementary processes are the most granular level of detail in a process model, representing the smallest units of work that cannot be broken down further.

Question 7

Primitive processes are the lowest level of detail when depicted in a process model.

Accepted Answer

Primitive processes are the most detailed level in a process model, representing the smallest unit of work that cannot be broken down further.

Question 8

A black hole is a process that has inputs but no outputs.

Accepted Answer

A black hole is a region of spacetime where gravity is so strong that nothing, not even light, can escape. This means that a black hole has inputs (matter and energy falling into it) but no outputs (nothing can escape from it).

Question 9

A black hole is an acceptable elementary process.

Accepted Answer

A black hole is not an elementary process; it is a complex astronomical object formed from the remnants of a massive star after it collapses under its own gravity.

Question 10

Gray holes can be caused by a misnamed process.

Accepted Answer

Gray holes refer to a type of network attack where data is selectively dropped, and the term can be misleading as it does not involve actual astronomical phenomena like black holes.

Question 11

A gray hole is a process where the inputs are insufficient to produce the desired outputs.

Accepted Answer

A gray hole is a process where the inputs are insufficient to produce the desired outputs.

Question 12

A data store represents data in motion.

Accepted Answer

A data store represents data at rest, not data in motion. Data in motion refers to data being transferred or processed, while data at rest is stored and not actively moving.

Question 13

A logical process can perform computations.

Accepted Answer

A logical process involves reasoning and decision-making, which can include performing computations as part of its operations.

Question 14

A logical process can make decisions.

Accepted Answer

A logical process involves reasoning and can be used to make decisions based on given information and rules.

Question 15

A logical process can trigger other processes.

Accepted Answer

A logical process can initiate or trigger other processes as part of a sequence or workflow in computing and programming.

Question 16

A logical process can use stored data to create, read, update or delete a record.

Accepted Answer

A logical process in computing often involves operations such as creating, reading, updating, or deleting records, commonly referred to as CRUD operations, which are fundamental to managing data in databases and applications.

Question 17

Structured English is a language and syntax, based on the relative strengths of structured programming and natural English, for specifying the underlying logic of elementary processes on process models such as data flow diagrams.

Accepted Answer

Structured English is a method used to describe the logic of processes in a clear and concise manner, combining elements of structured programming and natural language to improve understanding and communication in process modeling.

Question 18

An iteration structure specifies that a set of steps should be repeated based on some stated condition.

Accepted Answer

An iteration structure, also known as a loop, repeats a sequence of instructions until a specific condition is met.

Question 19

A repetition structure specifies that a set of steps should be repeated based on some stated condition.

Accepted Answer

A repetition structure, also known as a loop, executes a block of code multiple times as long as a specified condition is true.

Question 20

A conditional structure specifies that a set of steps should be repeated based on some stated condition.

Accepted Answer

A conditional structure specifies that a set of steps should be executed based on some stated condition, not repeated. Repetition based on a condition is typically handled by a loop structure.
