Not many people still know what a client server is . Even though this is important to know for people who want to enter the IT field and the like.
Client server itself is composed of two words with different meanings, namely client and server. However, the meanings of both are related to each other, so this term is often used by IT experts.
What is Client Server
As mentioned, client server consists of two words, namely client and server. What is Client Server ?. Client server is a type of computer network where the server serves client requests. This allows many users to have access to the same database at the same time, so the database will store a lot of information
The term client server is used to refer to the architectural or software concept that connects two objects, namely a client system and a server system.
Client Server Model
Even though we use a system like that, there are programs to maintain data security. Not only that, the server system also provides application management as well as data management which is carried out according to certain procedures. In the web access exchange function, the client server acts as a web browser program that presents information to users throughout the world.
In carrying out its functions, the client server system requires a web page and IP address from a special server. When a problem occurs, the client is given the freedom to request information from the server at any time. Based on these facts, it can be concluded that the client server uses the principle of two-way communication. In its implementation, a device is needed
A router is a device that forwards internet connections to clients connected to a server. It operates by directing data packets from one network to another based on IP addresses.
Functions of a Router in a Client-Server Network
Providing Internet Access
The router connects the server and clients to the internet through a connection from an Internet Service Provider (ISP).
Managing Data Traffic
The router directs and distributes data between the server and clients, ensuring smooth communication.
Implementing Network Security
Equipped with security features such as firewalls and encryption, the router protects data from external threats.
Providing Wireless Connectivity (Wi-Fi)
A router with Wi-Fi capabilities allows clients to connect to the network wirelessly without requiring LAN cables.
Managing IP Addresses
The router uses DHCP (Dynamic Host Configuration Protocol) to automatically assign IP addresses to connected devices.
Client Server Architecture
Client server architecture is a computing framework where multiple clients (users or devices) request services from a centralized server. This model is fundamental in networking, web applications, and database management.
Key Components
- Client – A device or application that initiates requests to the server (e.g., web browsers, mobile apps).
- Server – A system that processes client requests and provides responses (e.g., web servers, database servers).
Benefits
- Centralized control enhances security and resource management.
- Enables efficient data sharing and collaboration.
- Scalable architecture supports multiple clients simultaneously.
Common Examples
- Web applications (e.g., Gmail, Facebook).
- Online banking systems.
- Cloud computing services.

Benefits of Using a Client Server
Not without reason, client server development has its own mission, especially to facilitate community activities related to technology.
The existence of a client server even has the potential to increase data security and speed of access to various important data. Further, the discussion is below:
Reduce costs
Because it is connected to a central server, hardware or device usage costs can be reduced. How could it not be, client server users no longer need to buy a hard drive to store important data. Just use the storage service provided, then various important data will be stored safely in it.
Improve the performance
The concept used in the client server is believed to be able to improve performance because access to important data and information becomes more practical. No need to spend a long time looking for the data you need, just by utilizing the features in the server platform, the data you need will appear. The server used is multifunctional and is equipped with sophisticated programs.
Storing Big Data
The server provides cloud storage with supporting capacity to be selected according to needs. Cloud storage is proven to make things easier for people because it supports storing a lot of data ranging from small to large sizes.
The data entered in this storage can be accessed via devices connected to the internet network. Storage development is carried out with two concepts, namely consistent and server storage. The explanation is as follows:
- Consistent : A database that is stored with a consistent concept will increase data consistency. Because it supports multiple users accessing it simultaneously.
- Server storage : The server is equipped with large data storage to support its performance so that when users access the data, the loading process runs quickly.
Client Server Function
In general, the function of the client server is to save bandwidth and optimize the server’s role as storage for all client data. In practice, the client software will only get information according to the user’s request.
The good news is that most servers now use encryption security, allowing clients to get safe data. Recently, it has become very vulnerable to hacking. Therefore, it is important to have strong protection in a system.

Client Server Example
The client-server is responsible for data and application processing. The following is an example of a Client Server, including:
Web Browsers and Web Servers
- Client: Web browser such as Google Chrome, Mozilla Firefox, or Microsoft Edge.
- Server: A web server such as Apache, Nginx, or IIS that stores and serves web pages.
Email Client and Email Server
- Client: Email programs such as Microsoft Outlook and Gmail
- Server: An email server such as Microsoft Exchange, Postfix which functions to store and manage email.
Desktop Applications and Database Servers
- Client: Desktop applications such as Microsoft Access, MySQL Workbench, or LibreOffice Base.
- Server: A database server such as MySQL, PostgreSQL, or Microsoft SQL Server that stores and manages data.
Mobile Apps and Server API
- Client: Mobile applications such as Instagram, Tiktok, or Gojek.
- Server: API server that provides data and services to mobile applications.
IoT Devices and IoT Servers
- Client: IoT devices such as smart home smart door locks, humidity sensors, and wearable devices.
- Server: An IoT server that collects data from IoT devices and organizes it.
The Client and Server Don’t Support a Common SSL Protocol Version or Cipher Suite
The Client and Server Don’t Support a Common SSL Protocol Version or Cipher Suite, This error occurs when a client (such as a web browser) and a server fail to establish a secure connection due to incompatible SSL/TLS protocol versions or cipher suites. It often happens when one side supports only outdated protocols (like SSL 3.0 or TLS 1.0) while the other enforces newer, more secure versions (such as TLS 1.2 or 1.3). To fix this, update both the server and client to support modern TLS versions and ensure compatible cipher suites are enabled. Checking server configurations and browser settings can also help resolve the issue.
