What types of servers can be divided into?

Servers refer to software and hardware that can provide specific services to network users.

The role of the server:

It provides specific services for the network. People usually name servers after the main services they can provide. For example,Server rack cabinet a server that provides file sharing services is called a file server, and a server that provides print queue sharing services is called a print server.

How the server works:

If the server is compared to a person, the processor is the brain of the server, and the various buses are like nerves distributed in the muscles of the body. The chipset is a bit like a skeleton, and the I/O devices are like human hands,rack 42u eyes, ears, and mouth controlled by the nervous system. The power system is equivalent to the blood circulation system, delivering energy to various parts of the body.

As software, servers come in many forms: file servers, database servers, Web servers, mail servers, web servers, FTP servers, domain name servers, application servers, proxy servers, game servers, etc.

The hardware components of the server system include central processing unit, hard disk, memory, chipset, I/O bus, I/O devices, power supply, chassis and related software, etc., which have many similarities with the computers we usually come into contact with. However, due to the need to provide highly reliable services,server rack server there are higher requirements in terms of processing power, stability, reliability, security, scalability, and manageability.

The central processing unit (CPU), the brain of the server, is the primary indicator of server performance. Friends who have been in contact with local area networks must know that the server is an important device in the network, carrying the access of thousands of users. Therefore, the server has strict requirements such as fast throughput of large amounts of data, super stability, and long-term operation. At present, server CPUs are still distinguished according to the CPU instruction system, and are usually divided into CISC CPUs and RISC CPUs. Later, a 64-bit VLIM instruction system CPU appeared.

There are four common server shapes: tower server (also known as desktop server), rack server (rack), blade server (blade server), and cabinet server.

According to different computing capabilities and network scale, servers are divided into: workgroup-level servers, department-level servers and enterprise-level servers. The relationship between the three is that from workgroup-level servers to department-level servers, and then to enterprise-level servers, the requirements for the number of networked computers to be served, processing speed and data security, hardware configuration, system reliability, etc. are sequentially incrementally. And the corresponding services are small networks, medium networks, and large networks.

According to architecture, servers can be divided into: CISC architecture servers and RISC architecture servers.

According to the purpose, servers can be divided into general-purpose servers and dedicated (also called functional) servers. A general-purpose server, as its name implies, is a server that can provide various service functions. Most current servers are general-purpose servers. A dedicated server is a server specially designed for one or several functions. It is different from a general-purpose server in some aspects. For example, a CD mirror server is used to store CD mirrors, which requires a large-capacity and high-speed hard drive. Disc imaging software.
