Describe what is Client Server Computing ? And
Briefly describe the following Client/Server Terminology:
A) Application Programming Interface
B) Client
C) Middleware
D) Server
E) Relational Database
In client/server computing, a server takes requests from client computers and shares its resources, applications and/or data with one or more client computers on the network, and a client is a computing device that initiates contact with a server in order to make use of a shareable resource.
A)
An application programming interface (API) is an interface or communication protocol between different parts of a computer program intended to simplify the implementation and maintenance of software. An API may be for a web-based system, operating system, database system, computer hardware, or software library.
B)
Typically, a client is an application that runs on a personal computer or workstation and relies on a server to perform some operations. For example, an e-mail client is an application that enables you to send and receive e-mail.
C)
Software that connects two otherwise separate applications. For example, there are a number of middleware products that link a database system to a Web server. This allows users to request data from the database using forms displayed on a Web browser, and it enables the Web server to return dynamic Web pages based on the user's requests and profile.
D)
Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device.Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.
E)
A relational database is a set of formally described tables from which data can be accessed or reassembled in many different ways without having to reorganize the database tables. SQL statements are used both for interactive queries for information from a relational database and for gathering data for reports

1. Write a client program and a server program with multiple clients: Write a server application with multiple clients. This means your server program must use threads or fork methods to support multiple clients. You will use socket() and connect() system calls in Unix/Linux/Windows to write an application based on client/server socket programming. You can work on this project using either Java or C/C++. Through this assignment you will learn how to design a simple multithreading client-server programming using Java...
Describe when and why you should use PHP (as a server-side programming language). Why a client-side programming language (like JavaScript), not enough? Also, is it generally safe to keep credentials like the Database passwords in PHP source code? Why? Compare that to doing the same thing in JavaScript.

Sports Physical Therapy is considering upgrading to a client/server system. Use computer magazines, books, or the Internet to investigate one of the following web services: Application Programming Interface (API); Common Gateway Interface (CGI); Simple Object Access Protocol (SOAP); Universal Description, Discovery, and Integration (UDDI); or Web Services Description Language (WSDL). Then prepare a report that defines the web service, explains its purpose, and includes the potential advantages and disadvantages of its use by Sports Physical Therapy.
To develop a client/server application using TCP sockets and the C programming language that is capable of supporting multiple concurrent service requests from different clients. PROBLEM You are to use the Ubuntu operating system as well as both the client and the server programs. You are to modify your server program to process requests from more than one client concurrently. This means different clients may request either the same service or a total different one. The services supported by your...
Helpp: Make an application Protocol Application log for text messages In this task, an application protocol for sending and retrieving text messages is to be developed. A client (eg app on a smartphone) communicates with an application on a web server running a database of user data (username and password) and messages (user name of the sender, user name of the recipient, message text). The client should be able to perform the following actions: Register a new user Log in...
