What computer is Workstations?
A workstation is a Microcomputer designed to run engineering or scientific applications. The main purpose of creating this computer is to serve one person at a time. It can connect with each other via computer networks and serve multiple users at the same time. A group of workstations can handle the work of a Main Frame mainframe if connected to the network.
Workstation workstations are highly stable, have a strong configuration that provides higher performance and processing power than normal desktops. In particular, CPU, RAM, graphics card capable of multitasking. These components are optimized to handle specialized tasks such as 3D drawing, film editing, simulation design, graphic design and calculation …
Workstation computers can connect to multiple monitors with high resolution and other devices such as graphic tablets, 3D mice, etc.
What are the basic components of Workstation?
Processor (CPU)
Most specialized workstations often do not use the popular desktop CPU series such as Intel Core 2 Duo, Intel Core i series, AMD Ryzen, … The workstation computer lines often use specialized CPU lines such as Intel Xeon, AMD Ryzen Threadripper.
Those processors have features far superior to those of desktop processors such as processor speed, multitasking capabilities, high cache and advanced technologies. Other dedicated are integrated into the microprocessor.
In particular, the processor series for this workstation are also developers, software manufacturers writing independent software for these CPUs in order to help maximize the capacity that the CPU has as the sets Software of PTC, Autodesk, Adobe, …
Mainboard (Motherboard)
Workstation mainboards have more specialized features for workstations than desktop desktop motherboards:
– Use powerful chipset such as C602, x58, …
– Allow installing 2 CPUs on the same motherboard at the same time
– More RAM slots, more RAM channels, and the capacity to support the maximum RAM of the motherboard is also higher.
– Supports RAID feature to manage hard drives and support data backup better
– For continuous operation, high performance and stability
Memory
The dedicated RAM modules for workstation lines that are different from the desktop computers are the ECC (Error Correcting Code) feature. This feature helps computers when errors arise during use, the errors will be promptly overcome. Help workstation machine can operate continuously and do not freeze.
– Without ECC, a 4GB RAM system may experience about one error per week
– Errors generated during running can cause you to lose data
– ECC RAM automatically fixes 99.99% of the memory errors
Graphics Card (VGA display card)
VGA card is one of the indispensable components for workstation series. Currently, two famous graphics card manufacturers for workstations are Nvidia with the main product line is Nvidia Quadro and AMD is the FirePro series.
Graphic applications and software for workstations that require graphics power are divided into 4 levels: Professional 2D, Entry 3D, Midrange 3D and High-end 3D.
The graphics card for Workstation when measuring performance through Benchmark applications does not clearly show its superiority, because this graphics card has a Benchmark speed just a little more or even equal to the universal graphics card. But its strength lies in the fact that the manufacturer develops specific drivers for this graphics card series that are different from the drivers for ordinary cards.
While the popular graphics card line was developed for games and all applications without graphics optimization, the workstation graphics card is strictly tested by software vendors, and the driver is optimized and designed to blend perfectly with other parts of the machine such as CPU, Mainboard, RAM so that the performance is very high and the ability to simulate images very faithfully.
Ordinary graphics cards can perform images and 3D effects smoothly in the game, but when designing and rendering simulation, it is much more weak than specialized cards.
Hard Drive (HDD, SSD, …)
Workstation computers require hard drives to be able to access high-speed data and safely store data. To meet the above requirements, specialized motherboards for workstations are integrated with RAID technology. This allows users to mount and manage hard drives and RAID configurations to suit their needs.
Currently, there are 3 types of hard drives used for workstation models: SATA hard drive, SSD and SAS hard drive:
– SATA hard drive: large storage capacity, cheap price but data access speed is still quite slow, read / write speed usually ranges from 20 MB / s to 100 MB / s
– SAS (Serial Attached SCSI) hard drives: have better durability, higher data access speed (range 200 MB / s to 1Gb / s) but lower storage capacity than SATA hard drives
– SSD (Solid State Drive): this type of hard drive has faster data access speed (range of 500 MB / s to 3Gb / s), energy saving, compact size and no noise when operating compared to two types of SATA and SAS hard drives
To ensure large capacity and fast data access Workstation allows mounting 2 or more hard drives and CPUs with integrated RAID. So we can configure RAID to create fault resistance or increase access speed
You can improve performance while saving money by combining both SSD and SATA. SSD used as the hard drive containing the operating system and SATA as the hard drive containing data

Power Supply
Dedicated power supplies for Workstations workstations are all kinds of high-end computer resources. Must meet the standards of high efficiency, power saving, stable operation and other environmental standards.
Monitor
Workstation workstations often have large screens, 24 inches or more. It has wide viewing angles, true-to-life colors like Dell Ultrasharp monitors to make the processing of graphics tasks more realistic.
At the same time, these monitors often support many high-quality image connections such as HDMI, Display Port, DVI, … If there is a need to expand the workspace, users can equip an additional monitor Professional workstation video cards have the ability to support multiple connections and work simultaneously (depending on the capabilities and number of monitors supported by the graphics card).
Differences between Workstation and Server
– A server is the hardware / software used to make requests from other computers connected to it. A computer without a monitor, keyboard, and mouse.
– Workstations are higher-performance computers used for a specific task, usually the hardware and software on a workstation designed to provide the best performance in a type of job (digital graphics 3D techniques, video rendering, logic calculations, artificial intelligence …).
– The server is the central component of the network, meeting the service requirements in the network.
– The workstation can be connected to the network or independent systems like a normal computer
– Workstations have personal input / output devices such as keyboards, mice and video interfaces, while servers are not required to have individual IO devices. The input / output device is connected to multiple servers via a KMV switch in a server rack.
– Workstations have a GUI (Graphical User Interface), otherwise the workstation is used for specific scientific purposes related to an operating system designed with a CLI (Command – line – Interface), but servers are not required to have a GUI.
