Answers

Based on the information that is given, a steep reduction in the memory that's available is known as a memory leak.

A memory leak simply means a form of resource leak which occurs when a computer program manages memory allocations incorrectly in such a way that the memory that isn't needed anymore aren't released.

It should be noted that a memory leak is also a steady reduction in memory available on the heap to the point where it's exhausted. It can also be when an object that is stored in memory can't be accessed by the running code.

All variables are----------------------------------------------- help please

Answers

Answer:

variables are any characteristics that can take on different values, such as height, age, species I think

Answer

A variable basically works as a "placeholder" for anything that might change a majority of the time.

Examples

In science one may call a factor in a experiment that is subject to change a variable.

In math the term is used for a symbol that we do not know yet, such as x or y. Typically in math a variable is a letter.

In computer programming, variables are used to store information to be referenced and used by a computer program. They do give a way of naming data with a descriptive name as well so programs can be understood more clearly. When you go to assign values to the "variable" you are basically assigning individual variables such as the ones above in a way.

In high-tech fields, industry standards rarely change.

what programming language supports relational databases?

Answers

A programming language that supports relational databases is SQL (Structured Query Language)

Structured Query Language (SQL), is the principal method for communicating with Relational Databases.

A relational database is a group of data elements that are linked together by predefined connections. These elements are laid up in the form of a series of tables containing columns and rows.

Tables are utilized for storing data about the items that will be displayed in the database. A column in a database contains a specific type of data, whereas a field records the actual value of an attribute. The table's rows indicate a collection of linked values for a single item or entity.

Each entry in a database can be assigned a unique identity known as a primary key, and rows from other tables can be linked together via foreign keys. This data may be accessible in a variety of ways without having to reorganize the database tables itself.

Match each Animation category to its description

Answers

Answer:

Your photo is 100% correct

Explanation: protect question from longwinded or poor answers complete.

Motion path: move object on screen. Emphasis: make an object stand out. Entrance: move an object top the frame. Exit: move object out of the frame.

What is animation?

Animation is the process of creating the illusion of motion and change by rapidly displaying a sequence of static images that minimally differ from each other.

The terms commonly used in animation and video production:

The path that an object takes as it moves across the screen is referred to as its motion path. A straight line, a curve, or any other shape or pattern can be used.

The use of animation techniques to draw attention to a specific object or element on the screen is referred to as emphasis. This can be accomplished by utilising colour, size, movement, or other visual effects.

The animation of an object as it enters the screen or frame is referred to as its entrance. This can be accomplished through the use of various techniques such as a slide, a fade-in, or a zoom-in effect.

Exit: the animation of an object leaving the screen or frame. This can be accomplished through the use of various techniques such as a slide, a fade-out, and so on.

Thus, this can be the match for the given scenario.

Consider the following code segment, which is intended to store the sum of all multiples of 10 between 10 and 100, inclusive (10 20 ... 100), in the variable total.
int x = 100;int total = 0;while( /* missing code */ ){total = total + x;x = x - 10;}Which of the following can be used as a replacement for /* missing code */ so that the code segment works as intended?A. x < 100.B. x <= 100.C. x > 10.D. x >= 10.E. x != 10.

Answers

The code segment illustrates the use of while loops

Loops are program statements that are used for repetitive and iterative operations

The missing statement in the code is x>= 0

The code is meant to add numbers from 10 to 100 (inclusive) with an increment of 10.

At the beginning of the program, variable x is initialized to 100, and it is reduced by 10 in the iteration until it gets to 10

So, the condition must be set to stop when the value of x is 10 i.e. x >= 0

i.e. the iteration must be repeated while x is greater than or equal to 10

Hence, the missing statement is (d) x >= 0

In Java, a reference variable is ________ because it can reference objects of types different from its own, as long as those types are related to its type through inheritance.

Answers

Answer:

polymorphic

Explanation:

An example of polymorphic reference, suppose you have 3 classes: Main, Product and SpecificProduct. If SpecificProduct extends Product this means it is a product class but with something else to complement.

Say you want to reference an object of product in the main class, you can do it the classic way:

Product pd = new Product();

Or you can do it polymorphic, like this:

Product pd = new SpecificProduct();

The program will accept just fine because SpecificProduct is extending Product. When you do it like this, we say the reference you made was a polymorphic reference
