What is a server? Definition, Meaning, and Explanation
A server is a computer that runs a specific program or set of programs. Servers are used to run specific programs or sets of programs, store or distribute data, and provide dedicated network resources.
What are the types of servers?
Servers can be used for various purposes: Servers can be used for storage and management of data files, authorization services, and queueing print jobs for users. Servers are categorized according to their use: Servers can be divided into four categories based on their intended use - web server, mail server, application server, and virtual server.
- Web server
A web server is a computer that serves requested HTML pages or files. A web server can also support SMTP and FTP. A web server stores and delivers content to a browser using Hypertext Transfer Protocol (HTTP). Web servers are responsible for hosting websites. There are different types of web servers, each with its own capabilities and features. Web servers can be configured to host a variety of websites, depending on their needs and requirements.
- File server
A server is a high-powered computer that can speed up data sharing by storing and distributing files. Files can be stored on a file server for use by multiple clients or users, and the file server hardware you choose can be customized to maximize read and write speeds. These servers can store and distribute files, improving overall performance and allowing for faster data sharing. Files can be stored on a file server for use by multiple clients or users. File servers are high-powered computers that can improve network performance by speeding up data sharing. The file server hardware you choose can be customized to maximize read and write speeds, thus providing improved performance for all users involved in the data sharing process.
- Print server
A print server is a powerful tool that can help manage files and devices in a printing queue, which can speed up printing and reduce paper usage. Additionally, using a print server makes it easier to manage printing jobs, as all of the connected devices are accessed through one interface.
- Game server
Web servers are used to host websites on the internet. They receive requests from clients, and relay the requests to the correct web server software. Web servers can also be used for other tasks, like serving up images or videos. Mail servers are used to send and receive email. Mail servers can be configured to work with different types of mail clients, including those that use POP3, IMAP4, and SMTP protocols. Application Servers run different types of software applications on behalf of users. Common application server tasks include hosting files and databases for users, serving up Web pages, running messaging systems, and more. Virtual Servers are a type of server that runs as a separate process on a computer rather than being housed within the operating system itself. This allows virtual servers to exist in multiple locations at once without actually affecting how the computer operates. Virtual Servers are commonly used in conjunction with cloud computing services like Amazon AWS or Google Cloud Platform
- Streaming video server
A streaming video server is perfect for those who want to stream their videos with excellent performance. With this powerful server, you'll be able to stream videos in high resolution at 4k without any lag or buffering. The server is also capable of streaming videos in various formats, making it easy for you to share your content with your viewers.
- Proxy server
A proxy server is a computer that acts as a third party intermediary between two servers. By filtering content, speeding up internet traffic, and keeping unauthorized users from accessing the network, proxy servers are used by businesses to keep data safe and to ensure their workers only use permitted web functions.
- Email server
A mail server is a computer that receives and sends emails for users within the same domain. A mail server can also be used to send and receive emails for users who use a web-based program, such as Gmail or Yahoo!. If you want to access your email on a computer, you need to use an email server that supports your sending and receiving process.
- Database server
There are several different types of database servers, each with its own advantages and disadvantages. A relational DBMS is the most common type of database server, and it's used to store and manage data in a way that makes it easy for users to access and use. Relational DBMSs are powerful computers that can handle large loads, making them ideal for storing data for a network of users and devices. Other types of database servers include object-oriented DBMSs (which are more user-friendly than relational DBMSs) and NoSQL databases (which are designed to store large amounts of data without using relationalDBMS technology).
- Server virtualization software
A server is a computer system used to provide services to other computers, such as file storage or hosting websites. Server virtualization software is used to host multiple virtual machines on one physical server, which can then be used to run multiple applications simultaneously. Virtualization software helps to create multiple "simulated" copies of a computer, which can then be used to run different versions of the same application on different servers. Server virtualization software can also be used to run different versions of the same application on separate servers.
- FTP servers
A FTP server is used to securely transfer files between computers on a network. FTP servers are often found in an organization's back end, but they can also be found in the cloud. FTP servers use the IP protocol to connect devices and facilitate file transfers. FTP servers are useful for transferring files between computers in a local network or the internet.
What are the features of a server?
Servers are made up of various components and subcomponents. The physical components of a server are called hardware. The hardware that makes up a server can vary depending on the type of server that you're looking at. However, most servers contain a rack mount chassis containing a power supply, a system board, one or more CPUs, memory, storage, a network interface, and a power supply.
- Operating system
An operating system is defined as a software program that manages the hardware and software resources of a computer. In simpler terms, it is what makes everything on your computer work. There are different types of operating systems, but Windows and Linux are two of the most popular. Windows is typically found on personal computers, while Linux is often used for servers.
Computer memory is a storage device that temporarily stores data for use. This data does not persist when the computer is turned off or disconnected from the power supply.
4. Storage A hard drive stores data permanently i.e. data persists even after the computer is turned off or disconnected from the power supply.
5. Network A network connects one or more computing devices with each other. It comprises of physical wires and hardware and software. A telecommunications network is a complex of switches and links that allows for data transfer and exchange among multiple users. A network provides efficient communication between users by linking them together in a connected topology. Networks are designed to handle the high demand for communication while avoiding the wasted resources typically associated with point-to-point links. 6. CPUs A CPU is a central processing unit, or chip, in a computer. It performs the essential tasks of controlling and enabling the functions of the other components of the system.
7. Network interface cards (NICs)
8. Power supplies
10. Environmental factors
Server types include physical, virtual, and cloud servers.
Physical servers: A physical server is a computer that resides on a physical hardware system such as a rackmount or data hypervisor systems. Virtual servers: A virtual server is created by using software to create an environment on top of another computer where the software runs instead of the actual hardware. Cloud servers: A cloud server runs in remote storage and uses your own resources rather than requiring you to install any extra software on your computer or use someone else's resources (such as Amazon Web Services).
What are the benefits of using a server?
Servers are easy to add, upgrade, and relocate, making them a suitable choice for businesses with a lot of growth or change. Servers provide the business logic for an application program. Proxy servers act as intermediaries between users and servers, and mail servers receive and send emails. Virtual servers create the illusion that a user has complete control of a computer. Blade servers are multiple-server chassis housing multiple thin electronic circuit boards, which acts as a server in its own right. To determine which server resources are needed, it is important to think about the use case for which the server will be used.
What are the drawbacks of using a server?
Using a server for business can be advantageous in that it provides quick access to data and users. However, there are drawbacks to this model. For example, servers can be expensive to purchase and maintain and may require specific hardware or software to run correctly. Additionally, servers may require regular updates and security patches. Finally, server energy consumption can be high.
What are the different types of server architectures?
There are four main types of server architectures: One-Tier, Two-Tier, Three-Tier, and Four-Tier. Each has its own set of benefits and drawbacks.
- One-Tier architectures are the simplest type of server, and don't require access to the network. They're best suited for small businesses that don't need to share their servers with other organizations.
- Two-Tier architectures divide a computer into a client (the user) and a server. The client talks to the server, which runs the code. This architecture is popular in offices because users can use different applications without having to change their computers or learn new software. However, this architecture is more complicated than one tier because users have to know how to work with multiple tiers of software interpreters and servers.
- Three-tier architectures present information on one screen or computer screen at a time by dividing an application into three parts: presentation (such as graphics), application (which does the work), and data (which stores information). This architecture is most commonly used in business because it allows multiple applications to run on one computer simultaneously without causing interference or slowing down the system as a whole. It's also popular for gaming systems because it allows people to play games while they're working.
- Four-tier architectures are becoming more popular because they allow for increased scalability and manage dependencies. A presentation tier handles the graphics, sound, and user interface. An application tier manages the tasks the user wants to do, such as creating a document or compiling a program. A service tier provides support for common tasks, such as sending e-mails or streaming videos. Finally, data is stored in a separate layer that's off limits to users but accessible by applications in the application tier. This architecture is most commonly used in large organizations that have multiple applications that need to be accessed by different people at different times. It's also becoming popular in business because it allows for an increased number of users on one computer without causing interference or slowing down the system as a whole
