This article is to share with you about the importance of web servers in the Internet. The editor thought it was very practical, so I shared it with you to learn. The following information is about the network server.

Many people mistakenly think that a server is no different from a typical desktop computer. Although a computer has a processor speed, memory and storage capacity similar to that of a server, and a computer that meets any minimum hardware requirements can run a server operating system, this operating system does not make a computer a real server, nor can it replace a real server.

The composition of the server includes processor, hard disk, memory, system bus and so on, which is similar to the general computer architecture, but because of the need to provide high and reliable services, therefore, it requires high processing capacity, stability, reliability, security, scalability, manageability and so on. The difference is that the hardware of the server is relatively large, mainly performance-based, while the home machine is light and fast. The server is different from the general personal computer, the server supports not shutting down the computer all the year round (provide services, turn off the phone to whom to service), so the accessories on the server are different from the computer. The hardware requirements are much higher. And the server is not like a computer, a computer generally needs a hard disk, and the server needs a lot of pieces, so it will require a disk array (a way to improve disk access speed or security). The server is a high-performance computer, as a node of the network, it stores and processes 80% of the data and information on the network, so it is also called the soul of the network. It can also be said that a server refers to a computer software that manages resources and provides services to users, usually divided into file server, database server, and application server features:

1. Scalability.

The server must be "scalable" because the enterprise network cannot remain the same for a long time, especially in today's information age. Scalability is specifically reflected in whether the hard disk can be expanded, whether CPU can be upgraded or expanded, and whether the system supports a variety of optional mainstream operating systems such as WindowsNT, Linux or UNIX. Only in this way can we keep the early investment to be fully utilized in the later stage.

two。 Easy to use.

The function of the server is much more complex than that of the PC, which refers not only to its hardware configuration, but also to its software system configuration. It is inconceivable for the server to achieve so many functions without comprehensive software support. However, a large number of software systems may lead to a decline in the performance of the server, and managers can not operate it effectively.

3. Availability.

For a server, a very important aspect is its "availability", that is, the selected server can meet the requirements of long-term stable work, can not often have problems. In fact, it is equivalent to the Reliability proposed by Sun.

After reading the above, do you have any further understanding of the network server? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel. Thank you for reading.
