Resolving Client Server Network Problems Through Network Support
Article by Daniel Hughes
When personal computers started replacing the mainframe computers, the ClientServer Networking model became increasingly popular. Client Server Networking model refers to distribution application that partitions workloads between service providers and service requester. This model could be used on local area networks as well as internet. A server machine is a host that runs one or more server programs that share their resources with clients. A client does not share its resources. It always initiates communication with server requesting for server’s resources. PC support could be sought to setup client server networks.
ClientServer Network OperationApplications like database access,web access,email exchange are designed based on client server model. Using this model, a bank account holder could access account details and perform transactions. To view the account details, the user should send a request to the bank server using a web browser client. The server program would forward the request to it own database client program, which in turn sends the request to the database server. The database server returns the account details to the database client which then forwards the information to the user. Like these types of many business applications, internet protocols such as DNS,HTTP,Telnet and SMTP are also developed based on client server model. These network systems are well supported by many Network Support providers. Client and server are two separate computers, configured for their specific operations. One of the many differences between a client and server computers is that a client computer features large screen display, while the server computer does not require display. The best tool to describe the interaction between client and server devices is sequence diagram which is standardized in Unified Modeling Language. Typical examples of client applications are web browsers, email clients,online chat clients,etc, while the server models include database servers, web servers, FTP servers,mail servers, file servers, printer servers,etc. The design of server machine is quite complicated compared to client machines since one server has to handle several clients. Naturally technical problems might arise while using the server model, which should be solved with PC support.
Comparison Of Client Server Model To Other Networking ModelsThe necessity of enabling more users to share access to database applications led to the development of client server model. Scalability is improved on client server model in comparison to Mainframe model because connections could be made as required rather than being fixed. That made network support for this model much easier. Modular application is supported by this model, which made the job of software development less arduous. In two tier and three tier kinds of client server model, software applications are separated into different modules and each module is installed in either client or server. The alternative to client server networking model is Peer To Peer architecture which consists of two or more devices accessing individual resources like printers and disk drives. The shared resources are accessible to each device on the network, while each two of them communicate in a session. Each computer functions as server as well as client. That is why it is called peer to peer network. It’s main disadvantage is that it is less secure than client server network.
PC Support For Client Sever Network ProblemsThough the client server architecture is much better than monolithic architecture in many aspects, there are certain drawbacks for which network support is necessary. This model suffers from constant maintenance strain because of proprietary standards,technologies and lack scalability. To perform regular maintenance the user of the system should avail of the service of a PC support provider.
