Is it normal for a server to be upgraded and maintained for three or four days?

It can be judged by the following points.

1. Whether the company's official website and payment function can be used normally; If so, why does server upgrade and maintenance not affect the normal use of this function?

2. If you owe money, why do you need to go through the online transfer process, and you can't transfer it to a corporate or personal person.

3. Server upgrade and maintenance, if there are screenshots, you can come over and take a look.

Broadly speaking, a server refers to a computer system in a network that can provide certain services to other machines (if a PC provides FTP services, it can also be called a server). In a narrow sense, a server refers to some high-performance computers that can provide services through the network. Compared with ordinary PCs, the stability, security, performance and other aspects are higher, so the hardware such as CPU, chipset, memory, disk system, and network is different from ordinary PCs.

As the node of the network, the server stores and processes 80% of the data and information on the network, so it is also called the soul of the network. To make a figurative analogy: the server is like the switch of the post office, and the fixed or mobile network terminals such as microcomputers, notebooks, PDAs, and mobile phones are like the best machines scattered in homes, various offices, public places, etc.

The communication and communication between us and the outside world in our daily life and work must go through the exchange in order to reach the goal; In the same way, network terminal equipment such as microcomputers in homes and enterprises to access the Internet, obtain information, communicate with the outside world, entertainment, etc., must also pass through the server, so it can also be said that the server is "organizing" and "leading" these devices.

It's a bit long! Normally, it's just a day.

From a hardware point of view, a server is a physical server; From a software point of view, server refers to computer software with server-side functions, as well as server-side software that is running. The entire network is built by countless nodes and connection channels. On the "hard" side, it is built from a myriad of hardware servers and other digital computing devices, terminals, and intermediate connected devices.

On the "soft" side, it is made up of countless server-side software and client-side software > running

The system used by the server depends on the usage habits of the O&M. Win2003 system is no longer recommended, and there is no patch to update. If you use a win system, you can consider win2008 or win2012, pay attention to regular patches, and avoid ransomware viruses and the like.

If you consider security considerations, you can use the centos system and install management software, which is also more convenient to use.

"A server, also known as a server, is a device that provides computing services. Since the server needs to respond to and process service requests, the server should generally have the ability to undertake and guarantee services. The server consists of a processor, hard disk, memory, and system bus. ”

There are 2008 servers,,, 2000 servers,,Since 2000, it is safe,,, same as 2003, there are still a lot of ,,, new systems are not as compatible as before,,, system has bugs, too many, not recommended,,, if you know Linux, red hat is not bad,,, Microsoft's server OS is very expensive,

A server is a kind of computer that provides a server for the terminal client on the network (no matter what network), and has high availability, stability, and durability.

To put it bluntly, it is also a computer, with more different usages and different functions. Cooperate with professional software. will have different usages. But the whole is to serve other terminals on the network.

The server system is now commonly used is win-2003, 2008, 2012, 2018, etc., as well as the centos system, that is, the linux system, which is the most commonly used now, and there are others, but those are not commonly used.

If your system is important, we recommend using FreeBSD (or other Unix systems), and if not, we recommend using a Linux distribution. If it's just for fun, Windows will do the trick.

win2003 win2008 win2012 these are server systems, win8 is home systems.

Over time, I am slowly familiar with it, and the server system is not the same thing as the general computer operating system, I hope it can help you.

A server refers to a computer software that manages resources and provides services to users, and is usually divided into file servers, database servers, and application servers. The computer or computer system running the above software is also known as a server. Compared with ordinary PCs, servers have higher requirements in terms of stability, security, and performance, so hardware such as CPUs, chipsets, memory, disk systems, and networks are different from ordinary PCs.

In a local area network, a computer that runs management software to control access to a network or network resources (disk drives, printers, etc.) and is able to provide resources to computers on the network to operate as if they were workstations.

A server is a high-performance computer in a network environment that listens for service requests submitted by other computers (clients) on the network and provides the appropriate services. To do this, the server must have the ability to undertake and guarantee the service.

1. Differences in nature.

A server is a device that provides computing services. Generally speaking, the server should have the ability to undertake and guarantee the service.

A workstation is a high-end, general-purpose microcomputer based on a personal computing environment and a distributed network computing environment.

2. Differences in classification.

Servers are divided into two main categories according to the architecture: non-x86 servers, including mainframe, minicomputer, and UNIX servers; An x86 server is a server based on a PC architecture that uses Intel or other x86 instruction set-compatible processor chips and Windows operating systems.

According to the different software and hardware platforms, workstations are divided into: UNIX system workstations based on RISC architecture and PC workstations based on Windows and Intel. UNIX workstations are high-performance, professional workstations that are not compatible with each other for specific hardware platform applications.

3. Differences in characteristics.

The server is scalable, which is reflected in the expansion of the hard disk and the upgrade or expansion of the CPU; Ease of use is reflected in server operation, user navigation system, user-friendly chassis design, key recovery functions, operating system backup, adequate training support, etc. Availability, the selected server can meet the requirements of long-term stable work, and there can be no frequent problems.

The workstation has powerful data processing capabilities, an intuitive user interface that facilitates the exchange of information between man and machine, and can be connected to the computer network to exchange information and share resources in a larger range. The workstation provides comprehensive assistance to professional workers in programming, computing, document writing, archiving, communication and other aspects.

In terms of function, there is no difference at all, they are all computers, you can use them as ordinary computers, and you can use them as any of them.

But in terms of performance, there is a big difference. Servers and workstations are not the same as they are adapted.

The basic condition for the workstation to adapt to the environment is to be corrosion-resistant, and the temperature and humidity are relatively low, he is suitable for working in some chemical treatment, wilderness chambers and other environments, and his cost performance is in the ability to adapt to various environments.

The server will report errors when the humidity becomes higher or the temperature rises to a certain extent, but the heat dissipation performance is much stronger than that of ordinary computers, and it doesn't matter if it is turned on all year round, and its cost performance is in durability and the ability to process data.

The server is divided into hardware and software, and the hardware is those enhanced versions of the host, just like the host case of our computer, but the server is a little too long and can not use the monitor.

A workstation is a large server platform that is dedicated to some kind of large data storage or reading platform. The flow is very large and the load is very large.

The server is a static IP.

Direct IP is not good, you go to ping the server IP to see, if you can connect, but the ping can't get through the IP, generally there is something in the service on the server that is disabled, and all the related and network-related services are opened.

There is also the relationship between the firewall, I used to ping the IP because of the firewall, but I can connect.

If the ping does not pass the IP, the IP return cannot be directly connected.

The origin of this problem is the misuse of names by computer manufacturers, and the earliest computers did not have the term 'server'. A server is a software concept that provides information or services to other computers over a network called a server', The software responsible for receiving and interacting with the user is called the client client, and later because the manufacturer emphasizes the purpose of the computer, the computer that is specially used to turn on 24 hours a day and provide services through the network is called the server, the Chinese translation is different but the English is the same word as the server side of the software. Later, after the name spread, the server generally refers to those computers that work around the clock and are used to provide services to individual users through the network, which is essentially just a computer, so any computer with computing and network functions can be called a 'server' as long as it has server-side software running on it.

So not to mention personal computers, even mobile phones and tablets are 'servers' as mentioned above.

Of course, the current dedicated server has made a lot of specific settings in all aspects to suit the above use environment, such as dual network ports, ECC check, dual power supply or multi-power redundancy, hardware RAID hard disk, 15000 rpm SAS hard disk, advanced network chip (don't look at the gigabit network port, the server dedicated can withstand a considerable load, and the general personal network port has not been specially designed if it is subjected to high traffic impact, I heard that it will even **), Faster and larger network interfaces such as Infiniband and FC. In short, the design idea is that stability and performance are all over all.

In this way, both the server and the space can be built, but the difference is that the server is flexible, and the space is separated from a file in the server.

What is the difference between a computer host and a server? Today is a long time to see.

In addition to buying a domain name, you also need to have a corresponding space to place the content du, so that when someone else accesses your domain name, you can point to a specific space. A server refers to a computer that manages resources and provides services to users, which is used to place ** programs. Space is just a small area on the server that is divided by virtual software, similar to the server is a house, and the space is a room in it.

If your ** access is not large, you can start with the space first, and later ** the demand for visits is large, and you are considering other things such as VPS and the like.

Computer is a modern electronic computer machine used for high-speed computing, which can perform numerical calculations, logical calculations, and also have the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed.

A server is a type of computer that runs faster, has a higher load, and is more expensive than a regular computer. The server provides computing or application services to other client computers in the network, such as PCs, smartphones, ATMs and other terminals, and even large devices such as train systems.

Many people mistakenly believe that a server is indistinguishable from a typical desktop computer. Although computers have similar processor speeds, memory, and storage capacity to servers, as long as they meet any of the minimum hardware requirements can run a server operating system, this operating system does not make a computer a real server, nor does it replace a real server. The technology behind them is designed for different purposes.

What is the difference between a server and a PC?

The server specifications are higher, and the memory capacity is higher than that of the PC. Servers are designed to run around the clock. The components in the server can often withstand higher stress. A server is a computer that can support multiple applications running at the same time and can handle multiple simultaneous connections, whereas a computer cannot.

PC stands for Personal Computer and has become a catch-all term for all desktop computers. The term is often loosely used to identify any computer that uses AT and ATX form factors. The term server is also a widely used term to describe any hardware or software, whether on-premise or otherwise, that provides a service for use in a network.

PCs are not suitable for applications that are too complex. Whereas, the server plays a vital role and has a rich set of configurations and applications. The speed of the computer is slow compared to the server.

The server can run and handle virtual connections non-disruptively, and multiple clients can be controlled.
