   • What are some of the examples of Expressions?

     Expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

     • A constant is a fixed numerical value.
     • A variable is a symbol that does not have a fixed value.
     • A constant, a single variable, or a combination of a variable and a constant combined with multiplication or division is defined as a Term.

     Types of Expressions 

     There are three types of expressions: 

     Arithmetic Expression: This is the expression that includes only numbers and mathematical operators such as addition, subtraction, multiplication, division. 

     Example: 80-5 x 2, 20+5, 85 – 25 …

     Fractional Expression: This is the expression that includes fractional numbers and mathematical operators .. 

     Example: 6/4 – 5/2 , 20/10 +25/2 etc 

     Algebraic Expression: This is the expression that Contains variables, numbers, and mathematical operators.

     Example: 3x + 12y , 5x + 5y etc.....

   • What are the examples of attribute directive

     Top Answer

     Answered Jan 01, 2017 · 0 votes

     Directives can be used to manipulate DOM element. It's so useful when you wanna make a custom (third party) directive that can be used by other programmers in your team or world.

     Basically there are three types of directives.

     1) Structural Directive 2) Attribute directives 3) Component Directive(with template)

     1) Structural Directives usually manipulates structure of view/template. Eg. *ngFor

     will generate element according to your list count. *ngIf

     will display/hide view according to passed value.

     eg.

     <p myColor >Color me!</p> //<<< this helps you to grab DOM element using ElementRef and then I'll color it as shown below.-import { Directive, ElementRef, HostListener, Input } from '@angular/core';@Directive({ selector: '[myColor]'})export class HighlightDirective { constructor(private el: ElementRef) { el.nativeElement.style.backgroundColor = 'red'; }}

     here myColor

     is just an attribute directive

     as it is added to the DOM element as an attribute

     but this attribute doesn't accept any value yet.

     Now let's add a value to myColor

     attribute,

     <p [myColor]="color">Highlight me!</p> -

   • What are the Examples of Project Proposal?

     A project proposal is a detailed document that provides vital information about a proposed project. It acts as a guide in terms of conceptualizing, implementing, and managing the project, outlining clearly what objectives are to be achieved at various stages that include the resources required within the stipulated time. Project proposals exist to convince clients, sponsors, or decision-makers about the need for support for a project.

     Components of a Project Proposal

     A standard project proposal is made up of several important elements that offer a detailed description of the proposed plan. While specific requirements may vary based on organizational standards or the nature of the project, the following components are commonly included in project proposals:

     1. Title Page

     • Title of the Project: This should be a very short and specific title that captures the main theme of the project.
     • Organization Name: The organization or the person who submitted the proposal.

   • What are the safest kinds of authentication for a rtsp video stream? Any examples of URL implementations?

     Top Answer

     Answered Jan 31, 2017 · 2 votes

     Security for your video stream can focus on different areas - one is access/authentication and so long as you are passing the username and password over an encrypted link then this is a relatively standard level of security - having something more like two factor authentication would require a more complex set up which may be overkill for you.

     Another is protecting the video stream itself from being interpreted, copied or redirected - the safest approach is to encrypt the video stream itself if your camera supports this (many good quality security cameras will). Without this, even if you authenticate the user you run the risk of someone being able to view the video stream. It is worth being aware that even if you use SRTP Secure Real Time Transport Protocol, the encryption features are optional so you need to make sure they are enabled for full security.

     A third, and probably less usual concern but one which may be important depending on the application, is verifying that the video feed is actually coming from the camera or source you think it is. The typical approach to this is to have a key or certificate at the camera which it use to 'sign' or identify itself.

   • What are the best examples of natural keys in SQL?

     Top Answer

     Answered Nov 08, 2017 · 5 votes

     Invoice numbers, vehicle registration numbers, scheduled flight codes, login names, email addresses, employee numbers, room numbers, UPC codes. There are also many thousands of industry, public and international standards for everything from currencies, languages, financial instruments, chemical compounds and medical diagnoses. All of these are potentially good candidates for key attributes. Some sensible criteria for choosing and designing keys are: Simplicity, Stability and Familiarity (i.e. familiar within the business or other context in which they are used).

     Some people seem to struggle with the choice of "natural" key attributes because they hypothesize situations where a particular key might not be unique in some given population. This misses the point. The point of a key is to impose a business rule that attributes must and will be unique for the population of data within a particular table at any given point in time. The table always represents data in a particular and hopefully well-understood context (the "business domain" AKA "domain of discourse"). It is the intention/requirement to apply a uniqueness constraint within that domain that matters.

     For example, if my website requires each user to supply a unique email address when they register then email address may be a valid choice of key in the database supporting that website. The fact that there are other populations of people in other domains where email addresses are not required to be unique does not necessarily invalidate that choice of key for my website.

   When were vector graphics first used?

   • Vector graphics, composed of lines defined by mathematical formulas, were first used in computer displays in the 1960s and ’70s. The displays were essentially modified oscilloscopes, and vector graphics were used because the memory that would be needed for displaying raster graphics, or bit-mapped graphics, was too expensive.

   Why do we use computer graphics?

   • Images used in the graphic design of printed material are frequently produced on computers, as are the still and moving images seen in comic strips and animations. The realistic images viewed and manipulated in electronic games and computer simulations could not be created or supported without the enhanced capabilities of modern computer graphics.
