Pro ASP.NET Core 3 Flashcards
HTTP Server
manages incoming HTTP requests and outgoing HTTP responses
HTTP
Hypertext Transfer Protocol; a request-response protocol for the client-server
HTTP Request Methods
GET, POST, PUT, DELETE HEAD, TRACE, OPTIONS, CONNECT, PATCH
HTTP Response Codes
Information 1xx, Successful 2xx, Redirection 3xx, Client Error 4xx, Server Error 5xx; Examples: 100 Continue, 200 OK, 301 Moved Permanently, 404 Not Found, 500 Internal Server Error
Middleware
software that enables communication and management of data in distributed applications; described as “software glue”
URL Routing
allows you to configure an application to accept request URLs that do not map to physical files. A request URL is simply the URL a user enters into their browser to find a page on your web site. You use routing to define URLs that are semantically meaningful to users and that can help with search-engine optimization (SEO).
Dependency Injection
a technique in which an object receives other objects that it depends on; the intent is to achieve separation of concerns of construction and use of objects; one form of the broader technique of inversion of control
Inversion of Control (IoC)
a programming principle; it inverts the flow of control; used to increase modularity of the program and make it extensible
Flow of Control (Control Flow)
the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated; the emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language
Imperative Programming
a programming paradigm that uses statements that change a program’s state
Declarative Programming
a programming paradigm that expresses the logic of a computation without describing its control flow
Programming Paradigm
a style of building the structure and elements of computer programs
Cache
a hardware or software component that stores data so that future requests for that data can be served faster
Caching
reusing data stored in cache
Model Binding
allows you to map HTTP request data with a model; it is a bridge between the HTTP request and the language action methods; it makes it easy for developers to work with data on forms because POST and GET is automatically transferred into a data model you specify
Razor
components that form part of the Blazor framework; a markup syntax for embedding server-based code into webpages
gRPC
an open source remote procedure call (RPC) system initially developed by Google
Remote Procedure Call (RPC)
is when a computer program causes a procedure (subroutine) to execute in a different address space, which is coded as if it were a normal (local) procedure call, without the programmer explicitly coding the details for the remote interaction; this is a form of client-server interaction; in OOP RPC’s are represented by remote method invocation (RMI)
Remote Method Invocation (RMI)
invoking a method on a remote object
Distributed Object Communication
realizes communication between distributed objects; the main role is to allow objects to access data and invoke methods on remote objects
Distributed Computing
a field of computer science that studies distributed systems
Distributed System
is a system whose components are located on different networked computers, which communicate and coordinate their actions by passing messages to one another from any system
Distributed Program
a computer program that runs within a distributed system
SignalR
a free and open-source software library for ASP.NET that allows server code to send asynchronous notifications to client-side web applications; the library includes server-side and client-side JavaScript components
