What are Servers? Know the Definition, Functions, Benefits, Types, and How They Work.

What are servers? Server is a computer system that has special services in the form of data storage. The server will store various types of documents and provide information for users or visitors. In general, what is a server is a place that contains various kinds of data or documents that the client needs. The client computer requires the server to connect to the network or to request data contained on the server. In general, the main function of the server is to serve and be fully responsible for data requests from client computers. In addition, the server function is also to set access rights to the network that can be used by client computers. In addition, computers often also contain various information data, where the server has the task of providing services for the clients connected to it.

What is a server is a computer system that has special services in the form of data storage. The server will store various types of documents and provide information for users or visitors. Therefore, the server plays an important role in providing faster access to send or receive data available on the server. In its physical form, the server is in the form of a computer network and has a very large size with several supporting components, processors and large capacity RAM.

After knowing what a server is, it is important that you know the function of a server. Here are some server functions, namely:

1. Serving Client’s Computer Request

The main function of the server is to serve all requests from clients to be processed. Be it a data request or an application to be run by the client. To support these functions, servers usually use a fast and secure operating system. So, clients can work more effectively and of course safely.

2. Storing Data or Information

Another function of the server is as a place to store data sent from clients. The stored data can be in the form of complex types of documents and information. To be able to accommodate a lot of data, the server must have a large capacity. Thus, clients can store and access data shared with other clients.

3. Provide a Database to Run

The server also has the function of providing a database as data storage and processing. Usually large companies take advantage of this function to implement big data. Later, all data stored in the database can be processed and accessed by users. With this service, many companies can develop their business products.

4. Manage Data or File Transfer Traffic

Another function of the server is to manage communication and transfer of information to the client. You can imagine how busy the server is when many clients will make requests. For this reason, server devices usually have high capacities such as hard drives and RAM.

5. Safeguard from Evil Attack

The last function of the server is to protect the computer or website from hacker attacks. Every time there is a request for data from the client, the server will check the IP address and other information. If there is anything suspicious, such as a malware threat, the server can prevent access to that IP address. That way, the data stored on the computer or website can be kept safe.

After knowing what a server is and its functions, here are some benefits that can be obtained from a server, namely:

1. Ensure Data Security

With a server, you can maintain and store all your data more securely and monitored at all times. In addition, the data that you have stored can be accessed quickly according to your needs. And most importantly, you can also save data storage from your client computer device and can be routed to the server.

2. Save Cost

The next benefit, of course, is that it can save costs for buying data storage device needs. The server has provided greater storage capacity than the client computer in general. So you don’t need to buy too many computers or hard drives for your business data needs.

3. Ease in Data Management

Another benefit is that it can facilitate the process of managing various important documents and information that require quick handling. The server also guarantees data storage for a longer period of time. Currently cloud-based or cloud-based server storage is also available. Where, your data will be stored on the internet with a much larger storage allocation.

4. Optimizing the Collaboration Function Between Teams

The last benefit is being able to maximize collaboration and work between each team or department. Where, in a business, especially in the IT field, it requires every team to work not only offline. However, they are required to be able to work online or remotely. Thus, the server plays an important role in increasing the productivity of company employees or related agencies.

After explaining what a server is, here are some types of servers that you must know, namely:

1. Mail Server

Mail server is a computer network that serves users in exchanging messages to fellow users electronically. Mail servers themselves are divided into two categories, namely incoming mail servers and outgoing mail servers. Incoming mail servers consist of IMAP and POP3. IMAP (Internet Message Access Protocol) will store messages sent and received into the Mail Server. Meanwhile, POP3 (Post Office Protocol 3rd version) is an electronic message protocol for storing messages sent and received by PC Local Hard Drives. Mail server serves to exchange messages to fellow users with supported files in the form of images, text, and others.

2. File Server

One type of server on a computer is a file server. This type of server is a computer network that provides access in the form of disk locations containing images, music, videos, documents, and others. File servers are designed to allow users to store and retrieve data with computations via workstations.

3. Database Server

A database server is a collection of data obtained for later storage on a computer. The use of the database in this computer is intended to facilitate users in processing data. Simply put, a database consists of a collection of tables that store data and information. One of the database functions is to avoid duplicate data stored. A DBMS software can be set to be able to recognize duplication of data that occurs when inputted. This is because the nature of the database can be accessed by more than one user.

4. FTP Server

File Transfer Protocol (FTP) is an internet protocol that provides server data access on a network. The process carried out by FTP is using an ASCII code which is actually dangerous because it does not go through encryption in the transfer process.

5. Web Server

A web server is a network of computers that specializes in HTTP and HTTPS requests. Later, the web server will receive the code from the browser, then send it back in the form of a web page. In other words, the web is sent by the web server in the form of HTML and CSS documents, then processed by the browser into a web page that is easy to read by the user.

6. Proxy Server

A proxy server is a computer network that acts as an intermediary between the user and the web server. Every user who accesses the internet network, will pass the proxy first before proceeding to the web server.

7. DHCP Server

DHCP (Dynamic Host Configuration Protocol) is a type of server that runs IP address rental services and TCP/IP information to clients. Generally, operating systems such as Windows 2000 server, Window Server 2003, and GNU/linuk use this service. The DHCP function itself is to provide IP address services automatically to the requesting computer.

After we know in depth about what a server is, then this time we will discuss how a server works. Simply put, the server works when there is a request from the client who is connected in a network. For example, the client computer requests data or services from the server. After the request is received by the server, the server will start processing it and the results will be sent back to the client computer. For example, when you start by typing a website address in the browser, your computer will immediately act as a client requesting information from the web server. And then, the web server will provide you with any information on the website that is displayed in the browser.
