What is A Client?

A client used on home and corporate networks is any computer hardware or software that needs access to a service provided through a server. Clients are often thought of as a requesting programs or users in a client-server architecture. End-user devices typically include desktops, laptops, and smartphones.

In a client-server model, a  requests a service or a resource from a server in a computer network. The server can be located inside or outside the buildings.

What is A Client

How does a client interact  a server?

Clients interact with servers requesting data or resources that they cannot provide in a server architecture. Clients and servers can remain located in different areas and connected via a network. They can also be on the same machine and connect via inter-process communication.

A distributed application framework divides tasks among servers and clients. The client can perform functions commonly referred to as the client side, while the tasks that a server can perform are referred to as the server side.

Servers typically provide files, data, Internet access, external storage, or computing power. The server allows one or more programs to distribute these services to requesting clients.

Clients and servers communicate using a request-response messaging model defined by a communication protocol such as Transmission Control Protocol / Internet Protocol (TCP / IP). The protocol defines the language and the dialogue models used. For example, TCP maintains a connection between the client and the server until the end of a message exchange. TCP determines how application data is distribute, packets transmitted and received, and lost packets handled. If a server receives a big number of needs simultaneously, the recommendations are organized according to a priority-based scheduling system. A access control tools allow a user to manage access to servers.

Client-Side Vs Server-Side

The Client-side is an action or operation performed on the user side, while the server-side refers to activities or operations performed on a server.

For example:  JavaScript scripts are client-side because a browser, the client, executes them. Common Gateway Interface scripts are server-side because they are run on a server.

For example:  a server can be an application server, a separate computer, a database server, or a web server. When a package or device does not have the resources to operate, it acts as a client and requests a server, and that operation is performe on the server side.

Types Of Clients

The Following Examines The Four Conducts To Define Different Types Of Customers:

Big customer. Heavy clients provide most of the resources and data processing. These clients have minimal trust in a server; Instead, they do most of the operations on the side.

Thin client. These thin clients are highly dependent on a server for resources and most of the data processing.

Hybrid clients are a combination of thin and heavy clients. This  processes data locally but relies on a server to store persistent data.

Zero customers. Zero clients are thinner and more cost-effective than thin clients. These devices do not require any configuration and have nothing stored. They also consume less power than heavy or light clients.

Client-Server Examples

Examples of client-server:  relationships comprise web, file, and email servers. A web browser remains essentially a client that requests sheets from servers on the web. The browser is the client that sends the requests while a server in another location returns the Hypertext Markup Language (HTML) file. The computer that processes the request and returns the HTML file is a server.

File servers are computers responsible for storing and managing data files and allowing users to exchange information over a network without physically moving files. Examples of a file server include a network-attached storage device or a separate computer hosting shared files.
