Definition of Client

In the most general sense, a client is an individual or group that purchases goods or services provided by a business. The term is synonymous with "customer" and is central to business transactions. In the realm of computing, however, a client refers to a software application or a computer that accesses a service made available by a server as part of the client-server model of computing. Here, the server performs some task on behalf of the client. A client also initiates communication with the server by sending a request for services or data.

Origin of Client

The origin of "client" can be traced back to both the business and technological spheres. Historically, the term derived from Latin, where "cliens" referred to a person who was under the protection of another. In modern business parlance, the term evolved to mean anyone who seeks the expertise of a professional. Technologically speaking, the concept of a client as a part of a client-server model emerged alongside the development of networked computers, where distributed systems required a method to differentiate between the provider of a resource (server) and the requester (client).

Practical Application of Client

A practical application of the term "client" can be illustrated in the context of web browsing. When you use a web browser like Chrome or Firefox, the browser acts as the client. When you navigate to a website, the browser sends a request to the server that hosts the website. The server then responds by sending the data needed to display the website back to the browser. This interaction exemplifies the client-server relationship, which is foundational to the functioning of the internet.

Benefits of Client

The client model offers numerous benefits. For businesses, understanding and managing client relationships can lead to increased customer satisfaction, loyalty, and profitability. In computing, the client-server model provides a scalable and efficient framework for networked services. It allows multiple clients to access a central repository of data or resources, supports a variety of different client types and configurations, and facilitates centralized management and updates.


A client and a customer can often be interchangeable terms, referring to an individual or entity that purchases goods or services. However, "client" is sometimes used to describe a more ongoing, service-based relationship, while "customer" might be used for one-time transactions.

Yes, in computing, a client is a software application that accesses a service or resource provided by a server. For example, an email client accesses email services from an email server. such as fraud.

The client-server model is vital because it provides a structured framework for devices and applications to communicate over a network. This model allows for centralized resource management, scalability, and the efficient allocation of services to multiple clients.
