What is the difference between a server and a workstation computer? What are their biggest features?
One is mainly used to process data, and the other is mainly used to process graphics. They are definitely different. The new model Many servers also support GPU display cards. Older servers only have about 10M of video memory. They are mainly used by units and enterprises to process data. Graphics workstations are different. They mainly rely on display cards. , the video memory of the display card is very large, and it is generally used for processing pictures, comics and three-dimensional demonstrations
The server refers to the execution of corresponding application software in a network environment to provide online users with A high-performance computer that provides shared information resources and various services, its English name is SERVER. Since a server is a high-performance computer, its composition must be very similar to the computer (PC) we usually use, such as a CPU (central processing unit), memory, hard disk, and various buses. Wait, it's just that it can provide various private services (network, web applications, databases, files, printing, etc.) and other high-performance applications.
The high performance of the server is mainly reflected in high-speed computing capabilities, long-term reliable execution, strong external data throughput capabilities, etc. It is the backbone of the network and the core of informationization. Since the server is specially developed for specific network applications, there are great differences between the server and the microcomputer (ordinary PC) in terms of processing power, stability, reliability, security, scalability, manageability, etc. difference.
The biggest difference between servers and PCs is their reliability in a multi-user and multi-tasking environment. Users who use PCs as servers must have experienced sudden shutdowns, unexpected network interruptions, and the loss of stored data from time to time. This is all because the design and manufacturing of PCs has never guaranteed that too many users will Reliability in the industrial environment, but once a serious failure occurs, the economic losses it will cause will be unpredictable.
A server faces users of the entire network and needs to work 24/7, so it must have extremely high stability. On the other hand, in order to achieve high speed to meet the needs of many To meet the needs of users, the server is installed using a Symmetric Multi-Processor (SMP) and inserts a large amount of high-speed memory to ensure its operation. Its motherboard can install several or even dozens or hundreds of CPUs at the same time (the CPU used in the server is not an ordinary CPU, it is developed and produced by the manufacturer specifically for the server).
Of course, the memory aspect is also different. There are fundamental differences in terms of memory capacity, performance, technology, etc. In addition, in order to ensure sufficient security, the server also uses a large number of technologies that ordinary computers do not have, such as redundancy technology, system backup, online diagnosis technology, fault warning technology, memory error correction technology, hot-swap technology and Remote diagnostic technology, etc., enable most faults to be repaired in a timely manner without downtime, providing extremely strong manageability.
Workstation
A workstation, whose English name is Workstation, is based on personal computers and distributed network computing. It is mainly oriented to professional application fields and has powerful data computing and graphics. , image processing capabilities, high-performance computing machines designed and developed to meet the needs of professional fields such as engineering design, animation production, scientific research, software development, financial management, information services, and simulation simulations.
Generally speaking, workstations are mainly used in the following fields:
(1) Computer-aided design and manufacturing CAD/CAM: This field is regarded as the traditional field of workstations. The use of CAD/CAM technology can greatly shorten the product development cycle, while also reducing the difficulty of developing high-tech products and improving the design quality of products. In the field of CAD, whether it is as large as a building or as small as a component, graphics workstations have shown strong competitive advantages with their intuitiveness, high precision, and high efficiency.
(2) Animation design: The user groups are mainly TV stations, advertising companies, film and television production companies, game software development companies, and interior decoration companies. Television stations use graphics workstations to produce the opening animations of various TV columns; advertising companies use it to produce animated scenes for advertising programs; film and television production companies use it for computer stunt production; game software companies use it as a development platform; interior decoration companies not only use it Use a graphics workstation for design, and allow users to see the three-dimensional simulation renderings after decoration before decoration.
(3) GIS geographical information system: The customer groups it targets are mainly urban planning units, environmental protection departments, geographical and geological survey institutes, research institutes, etc. They usually use graphics workstations to execute GIS software. It allows users to understand the details of the project location and surrounding facilities, such as lampposts, underground drainage lines, etc., in real time and intuitively. These data-heavy operations can only be executed efficiently on workstations with professional graphics processing capabilities.
(4) Planar image processing: It is an industry with a high degree of application popularity.
Users usually use a graphics workstation as the hardware platform and software such as PhotoShop and CorelDraw as operating tools, focusing on image processing, advertising and promotional color page design, packaging design, textile pattern design, etc.
(5) Simulation: In the military field, simulation technology is an effective means of training fighter pilots, tank drivers, and simulating maritime navigation; in the field of scientific research and development, it allows designers to , you can perform simulation execution on the graphics workstation, discover problems in time, and modify the design. What is the difference between a VPS server and an independent host?
A VPS server actually divides an independent server into multiple independent virtual servers through unique virtualization technology. Some use VM technology, and some use A VPS separated by HV technology. At present, HiTeng Data's VPS is segmented through VM technology. There is also a cloud host, which uses cloud computing technology to integrate the resources of multiple servers and then divide them, which is equivalent to an upgraded version of VPS.
VPS servers and cloud hosting servers are suitable for small and medium-sized website customers. Their websites do not have enough space and it is too wasteful to use servers. Therefore, VPS and cloud hosting are his best choices and save money.
Generally, if a website has more than 2,000 daily IP visits, it is necessary to use a separate server. At this time, not only server hardware resources are needed, but also bandwidth resources.
What are the differences between the desktop version of Red Hat Enterprise Linux 6 and the workstation and server versions?
The difference is the Chinese name. The former is for individual users, while the latter is for enterprises. user's. The server version can support the internal and external network environment of an enterprise. It has many services and can be used as web, mail, ftp and other servers. The desktop version tends to operate on the desktop, just like ordinary windows, with graphics. The interface is good. What is the difference between a server and a computer?
The difference between a server and a computer:
1. High scalability
Scalability refers to the configuration of the server (memory, hard disk , processor, etc.) can be easily added as needed on the original basis.
In order to achieve scalability, the server chassis is generally more than twice the size of an ordinary chassis. There are two reasons for designing a large case: first, the interior of the case is well ventilated; second, the case is equipped with seven or eight hard drive bays, which can accommodate more hard drives.
The power output of the server is much greater than that of an ordinary PC, and it even has redundant power supplies (i.e. two power supplies). There are as many as a dozen D-type power interfaces for case power supplies, while ordinary PC cases only have five or six.
The memory of the server can be expanded as needed. Generally, the package can be expanded to several GB
2. High reliability
Because the server is on the network The server is working continuously on the road, so the reliability requirements of the server are very high. At present, the common way to improve reliability is to redundant configuration of components. The server can use ECC memory, RAID technology, hot-swappable technology, redundant power supplies, redundant fans, etc. to make the server (support hot-swappable function) fault-tolerant and safe, thereby improving reliability
Hardware redundant devices support hot-swappable functions, such as redundant power supply fans, etc., which can automatically switch to a backup device when a single component fails, ensuring the continuity of system execution. RAID technology ensures that the hard drive can be switched online when a problem occurs, thus ensuring the integrity of the data.
3. High processing power
The server may need to respond to dozens, hundreds, or thousands of client requests at the same time. Therefore, the server speed should be faster than an ordinary PC. quick.
There are many factors that determine CPU performance, and CPU is only one of them. Others, such as the speed of the hard disk, the size of the memory, the data throughput capacity of the network card, etc., are all important factors that restrict server performance. factor.
4. High I/O performance
SCSI technology, RAID technology, high-speed smart network cards, and larger memory expansion capabilities all improve the I/O of IA architecture servers effective way to achieve capabilities.
5. High fault-free execution time
Generally speaking, the requirement for a working server is that there are no faults during working hours (8 hours a day, 5 days a week); department-level servers Server requirements are 24 hours a day and no failures within 5 days a week; enterprise servers require no failures 24 hours a day, 365 days a year, and the servers are available at any time, referred to as 7x24.
6. High manageability
The IA architecture server motherboard integrates various sensors for detecting various hardware devices on the server. With the corresponding software, the server can be monitored remotely.
7. Execute the server operating system
A server is a system that combines hardware and software. Although a network operating system is installed on an ordinary PC, it can also be called server, but this server does not have the characteristics of a real server.
8. Providing network services
Servers that already have the corresponding hardware platform and operating system cannot yet play their role. If you want to play its role, network service software must be installed on the network server. What is the difference between a computer and a microcontroller?
A microcontroller is an integrated circuit chip that uses very large scale integrated circuit technology to combine the central processing unit (CPU), random access memory (RAM) with data processing capabilities. Integration of read memory ROM, various I/O ports and interrupt systems, timers/timers and other functions (which may also include display driver circuits, pulse width modulation circuits, analog multiplexers, A/D converters and other circuits) A small but complete computer system is formed on a silicon chip.
In other words, a microcontroller is a streamlined version of a general-purpose computer! What is the difference between a cloud server and a vps?
A cloud server is at least a dual-machine hot standby. In theory, there will be no hardware problems, and the stability and performance are generally better than VPS.
The VPS was set up on a server. Once there was a hardware failure, it crashed. What is the role of workstation/server networks in computing? Advantages and Disadvantages of Workstation/Server Networks
Workstations and servers are both relatively professional applications in computers. Workstations tend to process graphics, audio, video, etc., and have a huge amount of data, and the device configuration is relatively small. More professional for home and office PCs. The server network is biased towards communication and data exchange between computers. It includes point locations - computers and data connection channels between points - the network. It has considerable requirements on the stability of the machine and the real-time speed of data exchange. With the development of the Internet of Things, data processing will become larger and larger, and the server configuration will also become higher and higher.
Workstations and server networks are just computer application tools in different fields, and they have no advantages or disadvantages. Because the graphics workstation is equipped with a professional graphics card, it performs well in engineering drawing and 3D; because the audio workstation is equipped with a professional sound card, it performs exceptionally well in processing sound-audio. Other workstations are the same, with specializations. The server network is more focused on data transmission, stability, security, etc. Therefore, servers generally have multi-core, multi-processor, large memory, high-speed network card, high-speed disk, and excellent entire series of cards. The server has no special requirements for graphics cards, sound effects cards, etc.
Whether it is a workstation or a server, its basic configuration-cpu, motherboard, memory, etc. are incomparable to home and office computers. Workstations are definitely better than ordinary PCs. Servers used for the Internet generally have integrated sound cards and graphics cards, so they are not suitable for home and office use. For example, when playing games, it is definitely not possible to run the current Mass Effect 3 and Witcher 3 on a network server in a computer room, but a professional graphics workstation can. I personally feel that the pictures are more realistic and the colors are more realistic. Because the processing cores of today's high-end professional graphics cards are even far superior to those of mid- to low-end graphics cards for entertainment, listening to music on a professional audio workstation is also a professional-level enjoyment. There's nothing wrong with using a workstation for entertainment, it's just too wasteful. Through this, you can easily understand the simple differences between workstations, servers, and home computers.
I typed it by hand at 3 o’clock in the morning! ~~~~~ What are the differences between supercomputers, servers and personal computers?
A supercomputer refers to a computer cluster with strong computing power. It generally includes thousands of high-performance CPUs and has the strongest computing power. The scope of a server is very wide, but to put it bluntly, it is also a high-performance computer, used to provide external web pages, queries, storage or primary computing services, etc. It can be multiple CPUs or a single CPU, but the scale It's much worse than a supercomputer. A personal computer is an ordinary computer with only one or more CPUs (it is rare to use multiple CPUs as a personal computer, which consumes electricity). It can complete the Internet, program design, watch movies, play games, etc. Poor computing ability, not suitable for scientific calculations.
Supplement: The computing power generally refers to scientific calculations with a large amount of calculations, such as mathematical modeling, optimal path search, model solving, etc. I once used a personal computer (with an average configuration, P42.8) to calculate an optimal path, which took as little as 5 minutes and as much as 40 minutes. If I develop a program on such a computer, the cycle is too large and inappropriate, and I can't run many runs in a day. times, so a server or supercomputer is required.
