Client/Server Network

 Computer technology is leading to more accurate sizing and rating methods for process equipment.  Heat exchangers are designed with high-precision prediction methods and complex numerical techniques to account for the local flow and temperature conditions. Fouling mitigation is just changing from an art to a science-based technology. A long-term goal for the industry is to develop a knowledge-based system for designing and operating heat exchangers with a minimum impact of water fouling. We can find different contemporary technologies at this time including transportation, information technology, robotics, virtual reality, Internet of Things and many more.

CLIENT/SERVER NETWORK 

A client-server network is a central computer, also known as a server, which

hosts data and other forms of resources. Clients such as laptops and desktop computers contact the server and request to use data or share its other resources with it.A client server network is designed for end-users, called clients, to access resources such as files, songs, video collections, or some other service from a central computer called a server.The client uses the network as a way to connect with and speak to the server. The server will take the request and make sure that the request is valid.The server can make a request from the client as well. Client-server networking grew in popularity during the 1990s as personal computers became the alternative to mainframe computers. The client-server model can be used on the internet as well as on a local area network (LAN). Examples of client servers on the internet include web browsers and web servers, FTP clients and servers, and the DNS..

ADVANTAGES OF COMPUTER NETWORK

1) All files are stored in central location. 

2) Network peripherals are controlled centrally

3) Backups and network security is controlled centrally

4) Users can access shared data which is centrally controlled

 DISADVANTAGES OF COMPUTER NETWORK   

1) A specialist network operating system is needed.

2) The server is expensive to purchase.

3) Specialist staff such as a network manager is needed.

4) If any part of the network fails a lot of disruption can occur.

Client and Server Hardware

Client devices are typically PCs with network software applications installed that request and receive information over the network. In addition, mobile devices function as clients. Servers store files and databases, including complex applications and websites. Servers typically feature higher-powered central processors, more memory, and larger disk drives than client devices. 

Client-Server Applications

The client-server model organizes network traffic using a client application and client devices. Network clients send messages to a server to make requests of it. Servers respond to clients by acting on each request and returning the results.

One server supports many clients, and multiple servers can be networked together in a server pool to handle increased processing loads as the number of clients grows.  Some of the most popular applications on the internet follow the client-server model, including email, FTP, and web services. Each of these clients features a graphic or text-based user interface and a client application that connects the client to the server. In the case of email and FTP, users enter a computer name (or an IP address) into the interface to set up a connection to the server.

Local Client Server Network

Many home networks use client-server systems on a small scale.Broadband routers, for example, contain DHCP ( Dynamic Host Configuration Protocol) servers that provide IP addresses to the home computers, the DHCP clients. Other types of network servers found in a home include print servers and backup servers.         

                                             

Moreover, the client-server model supports modular applications that can make the job of creating software easier. In the two-tier and three-tier types of client-server systems, software applications are separated into modular components, and each component is installed on clients or servers specialized for that subsystem.It is one of the fastest growing part of computer network that provides a great advantages to us. Besides all the merits and demerits of client server network it has prove as the one of the best contemporary technologies for the entire world in field of science and technology.
