What is a Server: software for computers or apparatus that offers The term “server” refers to an entity that provides services to another computer program and its user, sometimes referred to as the “client”. The actual machine that a server application runs on in an information center is also commonly known as a server. It’s possible the device serves as an exclusive server or serves other functions.

A server program responds to customer programs’ requests, which may be operating on the same computer or on other machines, under programming in a client/server environment. Depending on the application, a computer may act as both a client and a server to other programs requesting services from it.

How to sever work :

A piece of real equipment, a virtual computer, or software that provides server services can all be referred to as servers. Depending on how the word “server” is employed, there are many different ways that a server might operate.

Physical and virtual servers

A computer used to execute server software is all that a physical server is. In the next section, the distinctions between a server and a desktop computer will be thoroughly covered.

A virtual server is a representation of a physical server in the virtual world. A virtual server has its own operating system and applications, just like a real server does. These virtual servers are maintained apart from any others that may be running on the actual server.

Installing a hypervisor, a lightweight software component, on a physical server is the first step in establishing virtual machines. Making the physical server capable of acting as a virtualization host is the hypervisor’s responsibility. The virtualization host makes one or more virtual machines accessible to the actual server’s hardware resources, including CPU time, memory, storage, and network bandwidth.

Administrators can assign certain hardware resources to each virtual server using an administrative console. Because numerous virtual servers may operate one individual physical server rather than each task requiring a separate physical server, this significantly reduces the cost of hardware.

Server Software

An operating system and an application are the two software parts that a server must have at the very least. The server application is run on a platform provided by the operating system. It offers the application’s dependency services and access to the hardware resources on which it depends.

Additionally, the operating system gives clients a way to connect with the server program. For instance, the operating system determines the IP address and fully qualified domain name for the server.

Desktop Computers vs. Servers

Desktop computers and servers have some similarities and some differences. The majority of servers run the same software as X86/X64 desktop computers and are based on X86/X64 CPUs. Physical servers frequently come equipped with numerous CPU sockets and error-correcting memory, in contrast to the majority of desktop PCs. Additionally, servers often accommodate much more RAM than the majority of desktop PCs.

As mission-critical workloads are frequently executed on server hardware, server hardware manufacturers build servers to handle redundant components. It’s possible for a server to have redundant network connections and power supply. A server may keep running even if a crucial component fails thanks to these redundant components.

In terms of form factor, server hardware differs from desktop hardware. Modern desktop computers frequently come in the form of tiny towers that may fit under a desk. Although some manufacturers still sell tower servers, the majority of servers are built to be rack-mounted. Depending on how much rack space they take up, these rack mount systems are referred to as having a 1U, 2U, or 4U form factor. For example, a 2U server uses twice as much rack space as a 1U server.

The operating system is another important distinction between a desktop computer and a server. Depending on the operating system, a desktop computer may be able to:

Although it has server-like features, it is not intended or authorized to replace an operating system for servers. An example of a desktop operating system is Windows 10.

Microsoft’s virtual machine platform, Hyper-V, is a part of some editions of Windows 10. While Hyper-V is compatible with both Windows 10 and Windows Server, Windows 10’s hypervisor is primarily intended for usage in development environments while the Hyper-V version bundled with Windows Server is created for operating production virtual servers.

There are licensing considerations to make even if a company might theoretically deploy a virtual server on top of Windows 10 Hyper-V. Resiliency features are also included in Windows Server Hyper-V which is absent from the Windows 10 version. For instance, failover clustering and virtual machine replication are supported by Windows Server.

A local network of devices may also access files using the Windows 10 operating system. But massive file sharing was never intended for Windows 10. However, Windows Server may be set up to function as a fully functional file server. To give superior performance, scalability, and resilience than what one physical server could provide alone, a distributed file system may be set up over an entire server farm in big businesses.

Types of Servers:

Servers are frequently grouped according to their function. Here are a few illustrations of the many server types that are accessible:

  • Web server
  • Web Server: a computer application that delivers HTML files or pages upon request. In this scenario, the client is a web browser.
  • Application server: a computer program that supplies the business logic for application software over a distributed network.
  • Proxy server: software that stands between an endpoint device, such as a computer, and another server from which a user or client is seeking a service, in order to facilitate communication.
  • Mail server: a program that passes outgoing emails for delivery after receiving incoming emails from local users (users on the same domain) and remote senders.
  • Virtual server: a server-sharing application that is set up to give each user the impression that they have total control over the server.
  • Blade server: a server chassis that holds several server blades—thin, modular electrical circuit boards. Each blade is a separate server that is frequently devoted to a single application.
  • File server: a computer in charge of managing and centrally storing data files so that other computers connected to the same network may access them.
  • Policy server: an authorization service that offers authorization services and makes it easier to track and regulate files.
  • Database server: A database or databases are hosted on this server. Database queries are executed by client programs to read data from or publish data to the server-hosted database.
  • Print server: One or more network-attached printers, or print devices as some server providers refer to them, are accessible to users through this server. The print jobs that users submit are placed in a queue on the print server. Depending on the job type or the person who submitted the print job, certain print servers have the ability to prioritize the tasks in the print queue.

server-side elements


There are several components and subcomponents that makeup servers. The standard hardware component of a server is a rack mount chassis that houses a power supply, a system board, one or more CPUs, memory, storage, a network interface, and a power supply.

The majority of server hardware has a dedicated network port that facilitates out-of-band administration. Independent of the operating system, low-level server management, and monitoring is possible with out-of-band management. Systems for out-of-band administration can be used to remotely turn on or off the server, set up an operating system, and check its health.

Operating systems

The operating system for the server is another element. The platform that makes it possible for programs to execute is a server operating system like Windows Server or Linux. The operating system facilitates network connectivity and gives programs access to the hardware resources they require.

The server’s ability to function is made possible by the application. A database application, for instance, would be run by a database server. Similar to a web server, an email server has to execute a mail program.

Choosing the right server 

When choosing a server, there are several things to take into account, such as virtual machine and container consolidation. Based on the use cases, determine which features are crucial when selecting a server.

A number of protection, detection, and recovery elements should be taken into account when thinking about security capabilities, such as native data encryption to safeguard data while it is in motion and at rest, as well as persistent event logging to keep a permanent record of all activities.

The selection of disk types and capacity is crucial if the server relies on internal storage since it can significantly affect input/output (I/O) and resilience.

As fewer physical servers can support more workloads thanks to virtualization, many enterprises are reducing the number of physical servers in their data centers. The amount of servers that must be hosted on-premises by an enterprise has also altered as a result of the rise of cloud computing.

Overall capital costs, data center floor space, and power and cooling requirements may be decreased by cramming more functionality into smaller units. Hosting more workloads on fewer boxes, meanwhile, can also raise the risk to the company since more workloads will be impacted if a server fails or needs to be taken offline for regular maintenance.

Physical components and the important settings of the system should be included on a server maintenance checklist.
