What Is a Server

A hardware-based server is a physical device connected to a computer network on which one or more software-based servers run alongside the operating system. An alternative term for a hardware-based server is host.



This video will help you understand what is a hardware server and how it work.

Today, servers come in a range of form factors and offer varying capabilities, finding a home in settings from small businesses to large enterprises.


Servers Concept

This concept makes it possible to divide tasks among different computers and allow users access to them simultaneously. Every service provided via a network requires a server (software), which is permanently on standby. This is the only way to ensure that clients, like web browsers or e-mail programs, always have the opportunity to access the server and utilize its service when needed.


Types of server hardware


Tower servers. A tower server resides in an upright, standalone cabinet, resembling a tower-style PC. These servers provide the benefit of easier cooling because they offer a relatively low component density.




Rack servers. A rack server, as its name suggests, is designed to be mounted on a server rack in a data center. Rack servers often play an all-around computing role in the data center, supporting a multitude of workloads.


Server racks are built to consistent size standards so that servers from multiple vendors can be stacked together.



Blade servers. A blade server is a compact device that houses multiple thin, modular circuit boards called server blades. Each blade contains a single server, which is often assigned to one application.


Blade servers offer greater processing density than other server types, providing a potential price and performance advantage.



Server hardware architecture The key components of server hardware architecture include the motherboard, processor, random access memory (RAM), and storage.


The motherboard resides at the heart of the server, providing the central processing unit through which system components are interconnected and external devices are attached.


The processor, or central processing unit (CPU), resides on the motherboard. CPU components include the arithmetic logic unit, floating point unit, registers, and cache memory. A server might also contain a graphics processing unit (GPU), which can support applications such as machine learning and simulations.


RAM microchips also plug into the motherboard, serving as a system's main memory. RAM holds the OS, applications, and in-use data for fast access by the processor. As for storage, a server might use a hard disk drive, a solid-state drive (SSD), or a mix of both.
