What is client/server architecture?

A client-server architecture may be a computing show in which servers have, give, and oversee most of the assets and administrations asked by clients. It is also called the network computing model or client-server network because all requirements and services are delivered over the network. A client-server architecture or model has other systems connected through a network where resources are shared by different computers. A client/server architecture is typically configured so that the client is a workstation or personal computer and the server is located elsewhere on the network, usually a more powerful computer. Such a model is especially useful when clients and servers perform routine tasks.

For example, in hospital data processing, the client computer is busy running an application program to enter patient information, while the server computer is running another program to retrieve and retrieve databases where information is persistently stored. you may be managing.  In addition, you can also check out our free General Awareness E-book- Download now for all competitive exams. 

How does client-server architecture work?

Customer/client: When we use the word “customer” we mean the person or organization that uses a particular service. Additionally, within the digital world, a client may be a computer (host). You can receive information from service providers (servers) or use certain services.

Server: Similarly, when we speak of the word server, it means a person or medium that provides something. Similarly, in this digital world, a server provides information (data) or access to a particular service. You want to remove the computer.
So basically, the client makes a request and the server processes it as long as it's in the database.

Applicable issue

• A client/server architecture is most useful for applications that require isolation. Abstraction of concerns between client and server. It is intended for high systems Interoperability. The client-server architectural style helps improve application performance and scalability.
• Client-server architecture design is paramount in systems that require separation of functions applicability. Request validation and entry can be handled client-side during load Balancers forward requests to servers for appropriate processing. the server is Responsible for processing customer requests and returning results via the correct protocol. These layers (client and server) perform tasks independently of each other and are useful for abstraction functionality; e.g. clients don't need to know how the server works to cover user authentication or request validation.
• Separation of functions improves the functionality of each layer Efficiently at scale. The latest technology has been developed within the client-server. An architecture that solves scalability challenges such as load balancing, sharing, and partitioning. These techniques improve the performance of multiple server-side requests architectural requests/users.

Advantages of the client-server model:

A centralized system with all your data in one place. Cost-effective, low maintenance costs, and data recovery. Client and server capacities can be changed independently.

Drawbacks of the client-server model:

Clients are vulnerable to viruses, Trojan, and worms when they reside on or are uploaded to a server. The server is defenseless to Denial of Service (DOS) assaults. Information parcels can be spoofed or modified in travel. Phishing or collecting client qualifications or other valuable data is common, as are MITM (man within the middle) assaults.

Some examples of client-server architecture

Email Servers: Email has replaced traditional email as the primary form of corporate communication due to its simplicity and speed. Email servers, supported by various brands of proprietary software, send and receive emails between parties.

File servers: Use file servers to store files in cloud-based services such as Google Docs or Microsoft Office. A file server is a central storage location for files accessed by many clients.
Web Servers: These high-performance servers host various websites and are accessed by clients over the Internet.

Here's a step-by-step breakdown:

• The customer/user uses her/his web browser to enter her/his URL of interest.
• Your browser requests your IP address from the Domain Name System (DNS).
• The DNS server finds the IP address of the desired server and sends it to the web browser.
• The browser makes HTTPS or HTTP request The server/producer sends the correct file to the user
• The client/user receives the file sent by the server and the process repeats as needed.
