Answer:

Relationship between external entities

Explanation:

There are four primary components in all data flow diagrams: entity, process, data store and data flow.

  • External entity

Also recognized as performers, sources or sinks, and terminators, internal entities generate and consume information flowing between the diagramming entity and system. These data flows are the DFD's inputs and outputs.

  • Datastore

No activities are generated by a data store, but it merely maintains data for subsequent access. Data stores may consist of long-term files or a batch of documents stored for a short time while waiting for processing.

  • Dataflow

Dataflow between external entities, procedures and information shops is depicted by an arrow symbol indicating the flow direction.

what statement about constructors is false? group of answer choices all constructors are passed a pointer argument constructors
Hunter-Best [27]

A return type cannot exist in the constructor. It ought to produce and deliver fresh objects. Consequently, a compilation error would result.

Including a return type in a constructor declaration is not allowed. A constructor has to accept one or more input parameters. In the absence of explicitly declared constructors for the class, Java will give a default constructor. The name of the constructor should match the class name. 2) The compiler will automatically produce a default parameterless constructor for a class if you don't define one. 3) All instance variables are initialized to default values, such as 0, null, and super(), by the default constructor.

Answer: B

Explanation:

WHATS GOOD DAVE STRIDER? WHATS UP MAN I -  i man put the bunny back in the box what pumpkin apple juice?

ok so application software performs specific tasks for an end user and utility software just runs routine maintenance on your computer to ensure it runs smoothly. in this sense, the answer is B because if your computer crashed then you have no backup. things do not run smoothly obviously.

think of utility software as things such as antivirus, compression tools, defragmenter, and the other boring stuff that is meant for your computer to run smoothly
