 application server


The user can approach an application through this host. Even without having to install the same in on their computers. In fact, the main client of this server is any computer with a web browser.


  • It provides a centralized configuration.
  • It provides access to the entire database with security benefits. Moreover it takes responsibility for authentication of an insecure client.
  • The user can get entry to updated data.
  • Therefore, it improves the performance of the client computer.


  • It takes a lot of time to develop application software.
  • Moreover, it may carry the real threat of viruses or malicious programs.

2. Catalog Server

A catalog program provides the list of information, data or programs stored on the network. In other words, it is an indexed computer system. That provides indexes of database, information, files and programs. That is available by searching even a related keyword.

  • It doesn’t provide the exact location.
  • The links of the index can be broken and unavailable at the moment.

3. Communication Server

The communication computer system is open in nature. It also carries common platforms for various communication platforms. As it specifically operates communication applications only to allow communication. But at the same time, it provides much flexibility, openness and carrier-grade to conduct a focused communication.

Communication network


The communication program is mainly used to build a network of infrastructure elements. The deployment elements are IP Multimedia Subsystem, Wireless broadband and IPTV.


  • It reduces the number of interfaces needed.
  • It also needs less maintenance and documentation as well.


  • The security will be less.
  • The structure of this host is expensive.

4. Computing server

The computing system provides the functionality to the computer. It is driven by the computer program. Consequently, it provides access to various services, data, programs, etc.

 serve Computing


This is mainly in use to provide a wide variety and vast amount of resources. For example CPU and RAM over the internet connection. Any computer system requires more CPU and RAM power. So, we can get access to this computer system.


  • It provides access to a large amount of data and programs.
  • The computing system provides resources to improve the functioning and performance of the system.


  • The cost of this high utility host is high.
  • This program sometimes fails in the transition.



Its uses for database applications to provide access to the database and all the programs to the requiring computer system. The user computer can get access either through a front end program or the back end. The host provides access to central as well as primary locations.

Purpose of Database

The major purpose of this computer system is to provide access to all types of databases. Moreover, the most widely used database is spreadsheets, software like asset management and accounting.

Advantages of Database

  • This provides better performance and wide scalability.
  • The database system provides automatic recovery of the database to the client.

Disadvantages of Database

  • The data can get malicious.
  • The hackers can steal the confidential database.

5. Game server


The Gaming computer system provides access to event multiplayer video games. To function the game, the system demands huge internal storage. While it allows users the access video games in proper format and with high speed.


The gaming system provides key to gaming devices. Therefore, it gives multiplayer video gaming experience to the gamers. The major clients of this hosts are personal computers and gaming consoles.


  • The additional support of the program optimizes the gaming experience.
  • Hence, the system improves gaming performance.


  • This takes lots of time and money to invest.
  • Besides, the gaming computer does not provide any security to the client.

Next section is about Advantages and Disadvantages of Server.

Advantages of a Servers

The advantages of a Server computer are:

  1. scalability,
  2. seamless connectivity (remote and email), collaboration,
  3. speed, and automated backups.

Disadvantages of Servers

These are the server disadvantages

  1. They often appear when the site experiences a significant surge in traffic as a result of resource conflict with other customers of the firm providing the service.
  2. Customization of the hosting service is not possible at this time.
  3. It is possible for the host to get overloaded, causing the site to go offline.
