What is a client and a server?

 


A client is a computer hardware device or software that accesses a service made available by a server. The server is often (but not always) located on a separate physical computer.

A server is a specialized computer or software system designed to provide services, data, or resources to other computers, known as clients, over a network. These services can range from delivering web pages and email to storing and managing files or running applications. Depending on the service that is running, it could be a file server, database server, home media server, print server, or web server. A Server organizes and stores information, ensuring it is accessible, reliable, and secure for anyone who seeks it.

What are different types of non-functional tests

                                                                   Non-functional testing plays a vital role in software testing by examining the non-functional characteristics of a software application. In contrast to functional testing, which checks if the software executes its intended tasks accurately, non-functional testing evaluates the software's performance under different conditions. This encompasses aspects such as performance, scalability, reliability, usability, and security, among other factors. OBJECTIVES OF NON-FUNCTIONAL TEST §   The goals of non-functional testing include enhancing the usability, efficiency, maintainability, and portability of the product. §   It aims to minimize production risks and costs related to the non-functional features of the produc...
