Q & A

Слайд 7

Client-server architecture
Client/server architecture is a producer/ consumer computing architecture where the

server acts as the producer and the client as a consumer.
The server houses and provides high-end, computing-intensive services to the client on demand.
These services can include application access, storage, file sharing, printer access and/or direct access to the server’s raw computing power.

Слайд 8

Client-server architecture
Client/server architecture works when the client computer sends a resource

or process request to the server over the network connection, which is then processed and delivered to the client.
A server computer can manage several clients simultaneously, whereas one client can be connected to several servers at a time, each providing a different set of services.
In its simplest form, the internet is also based on client/server architecture where web servers serve many simultaneous users with website data.

HTTP
The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed,

collaborative, hypermedia information systems.
This is the foundation for data communication for the World Wide Web (i.e. internet) since 1990.
HTTP is a generic and stateless protocol which can be used for other purposes as well using extensions of its request

URI and URL
Uniform Resource Identifier AND Uniform Resource Locator (Browser)
A

Uniform Resource Identifier (URI) provides a simple and extensible means for identifying a resource (straight from RFC 3986). It’s just an identifier; don’t overthink it.

A URI is an identifier.

A URL is an identifier that tells you how to get to it.
