Large-scale organizations and businesses can now interact across different locations by utilizing network models, through which they can access a shared database.
A client-server network is a model architecture that ensures these advantages. The security measures incorporated within the system make it more favorable compared to other existing network models. Continue reading this article to understand the unique characteristics of a client-server network and how the system functions.
What Is a Client-Server Network?
Clients are end-users who request data or services provided by a server. The server is a computer that communicates with all the clients.
A client-server network enables clients to access shared files and resources from a central server. The server reacts to the clients' requests and ensures security for the connection. This interaction takes place via a Local Area Network (LAN) or a Wide Area Network (WAN).
Furthermore, this network's operations regulate traffic between clients and servers, or between servers themselves. An designated server retains the client's request for establishing and maintaining a network interaction until the request has been fulfilled.
The table below outlines some pros and cons of a client-server network.
| Advantages | Disadvantages |
|---|---|
| This network ensures that only authorized users can access the resources and services shared in the network. Security controls can be implemented for access. | The restrictions prevent an easy change of information or work done on the documents shared in the network. |
| A client-server network is easy to set up and configure. The absence of multiple servers makes it easy to troubleshoot. | This model setup and maintenance is cost-intensive. The strong networks needed are usually expensive and not affordable for some users. |
| Hosting all information on one central server makes problems easier to resolve. Hence, management operations are faster. Also, regular updates are not cost-intensive. | A breakdown in the connection will prevent any client from retrieving the required information. This can subject certain organizations or businesses to risk. |
| The network model has better flexibility because interactions are created when necessary and not fixed. Modular applications are allowed for easy software creation. | A competent network manager should be hired to resolve any error once it occurs. This is because the servers run continuously and require proper maintenance. |
| The Client and server proximity is not a problem, as data can be transferred effectively without obstructions. | Client-server networks are not advisable for small-scale networks that do not require tight security measures. |
| Expansion of this network is possible without interfering with the existing system. Network segments, servers, and computers can be added without triggering downtime. | This system is prone to overloading if resources needed to service all clients are not available. The connection may break down if all clients attempt to interact at the same time. |
| Retrieval of backup data is easy with a single server. This advantage is peculiar to client-server networks, unlike other networks which require backup at every workstation. | The clients are not permitted to provide services or request services not granted by the central server. |
How Does a Client-Server Network Work?
The user devices can be a computer or a mobile device with an application installed. The user, acting as the Client, sends a request to the host server expecting a response and subsequently disconnects from the network once the request is completed. The speed of delivery will be determined by the Client's bandwidth capability.
This model structure is utilized in a Local Area Network (LAN) or the internet. Users communicate with servers using the TCP/IP protocol. The TCP protocol breaks down data into transmittable packets. As a connection-oriented protocol, it governs the transmission, flow, and receipt of these packets.
The IP protocol handles each request packet as separate units of data, and its stack doesn't establish a connection between the communicating endpoints. Both protocol stacks incorporate elements of the network layer within the Open Systems Interconnection (OSI) model for communication.
What Are the Types of Servers?
Clients depend on computer networks for data dissemination. Once the connection is established, servers determine whether to discard, accept, or reject user request packets. A properly configured server can terminate a connection without impeding the system's functionality. Here are the various types of servers in use.
1. Print servers
These servers can serve multiple clients located nearby. Computers within a department can utilize a single printer through network connections.
2. Web Servers
Computers and internet websites collaborate to exchange data stored on web servers. This interaction is facilitated through the use of HTTP codes, which retrieves the information onto users' devices.
3. Mail Servers
These servers provide users with platforms to access email services without installing software.
4. Gaming servers
Clients can access extensive gaming networks through these servers, where multiplayer engagement is facilitated.
5. Virtual Servers
Virtual machines can be operated on a single hardware, with data transferred and stored in virtual spaces.
Final Words
Client-server networks improve connectivity and data sharing among multiple users through a central server. This network model's advantages make it more favorable than peer-to-peer network systems. The TCP/IP protocol governs the transmission of network packets between devices.
It ensures maximum security for organizations within the network and closely monitors client access. This article will shed light on the functioning of a client-server network and the associated disadvantages.
