Server is a special service in the form of data storage. Server is a computer network that has a very large storage size.

At first glance, servers have various devices such as processors and RAM that are different from ordinary computers, having a larger capacity. Servers are instrumental in the operation of computer systems that require a large amount of storage and high performance.

Using a server is very important for providing faster access to services to send and receive data and information on an accessible server. The server can operate as long as there is hardware as an intermediary.

This article will explain more about servers. Starting from understanding servers, 7 types of servers, functions, to how they work. Check out the following explanation.

This service aims to provide a lot of convenience and indeed almost everything aims to make it easier for clients or users. To enable faster access services to send or receive data and information available on the server, the server is physically formed as a computer network and consists of a number of components supporting processors and RAM.

Servers are very useful in the use of computer services that are clustered and require further classification. Servers are quite effective devices for categorizing users both and generally by location.

An example of such a server is a location-based server. Suppose if the user is playing an online game, and the user's location is connected to the device, then it will be connected to the server that corresponds to the user's location.

But nowadays, a web server is a server that is able to connect the browser with various kinds of hardware such as printers and others.

2. Mail Server

Mail server is a type of server that focuses on mail delivery and digital correspondence. This type of server will serve users and visitors in exchanging messages with other users digitally. Well, the difference with other types of servers, Mail server has two types of servers, namely incoming and outgoing mail servers.

For incoming mail providers, there are several types such as POP3 and IMAP. POP3 is an electronic messaging protocol that stores sent messages and is stored on the local computer. Then IMAP is a protocol that always stores a copy of the sent message into the Mail Server itself.

Broadly speaking, a mail server is a server that serves to accommodate the exchange of messages and digital correspondence for its users.

This proxy will also detect any interference or suspicious internet access. If there is a user or internet access to a suspicious Web server, it will be completely blocked by the Proxy server.

Examples of Proxy servers are VPN services as well as browser DNS. 

6. FTP Server

2. Set Client Computer Access Rights to All Networks

A server will set the client's computer access rights once the client logs into the server. This server will give the client the authority to choose which network the server can connect to. So that the entire network will be more easily synchronized.

3. Protecting Client Computers With Malware Services

A server can protect client computers from malware attacks. Some types such as Proxy servers will provide several options and recommendations to protect computers from malware attacks, especially on websites that are less encrypted.

Closing

Thus the explanation of this article regarding servers. As the name suggests in Indonesian, namely servers, servers provide services in the form of delivery and containers for users to operate computers with other users according to their needs.
