The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. [1] Often clients and servers communicate over a computer network on separate hardware, but both client and server may reside in the same ...
In a computer security context, server-side vulnerabilities or attacks refer to those that occur on a server computer system, rather than on the client side, or in between the two. For example, an attacker might exploit an SQL injection vulnerability in a web application in order to maliciously change or gain unauthorized access to data in the ...
Typically, a client is a computer application, such as a web browser, that runs on a user 's local computer, smartphone, or other device, and connects to a server as necessary. Operations may be performed client-side because they require access to information or functionality that is available on the client but not on the server, because the ...
Frontend and backend. In software engineering, the terms frontend and backend (sometimes written as back end or back-end) refer to the separation of concerns between the presentation layer ( frontend ), and the data access layer ( backend) of a piece of software, or the physical infrastructure or hardware. In the client–server model, the ...
A server-side dynamic web page is a web page whose construction is controlled by an application server processing server-side scripts. [1] In server-side scripting, parameters determine how the assembly of every new web page proceeds, and including the setting up of more client-side processing. A client-side dynamic web page processes the web ...
The process of generating stubs involves creating a client-side proxy object that provides the same interface as the remote service, but routes method calls to the actual remote object. In distributed computing , a stub is a piece of code that converts parameters passed between the client and server during a remote procedure call (RPC).
A key element of server-side programming is server-side scripting, which allows the server to react to client requests in real time. Some popular server-side languages are: PHP: PHP is a widely-used, open-source server-side scripting language. It is embedded in HTML code and is particularly well-suited for web development.
HTTP functions as a request–response protocol in the client–server model. A web browser, for example, may be the client whereas a process, named web server, running on a computer hosting one or more websites may be the server. The client submits an HTTP request message to the server.
