Types of round power connectors at the monitor. Types of computer video card connectors

In order for your monitor and computer together to work, you should use a specially intended cord, which is suitable for connectors, both on the monitor and on the system unit.

So, let's deal with how there are monitors connectors that are designed to connect displays to a computer.

Types of monitor connections:

VGA (or Video Graphics Array) - This is an analog connector that is designed to connect the monitor to system block. This standard was created by the company called IBM in 1987 specifically for PC / 2 PCs. By the way, they also used a video card with a similar name. She had no great permit - 640x480 pixels.

The maximum resolution without loss of quality at the VGA format reaches 1280 × 1024 pixels, and the maximum image update frequency is 75 Hz.

DVI (Digital Visual Interface) - This is the world's first digital video interface, which was developed in 1999. The maximum resolution of this format reaches 1920x1080 pixels, however, if you use more advanced and respectively expensive graphics cards that support the ability to transmit a picture in two-channel mode, then the resolution increases significantly and reaches a 2560x1600 pixel.

It is worth noting that the DVI-I connector supports the possibility of transmission not only digital, but also an analog VGA signal.

Well, since DVI is far from the most compact connector, then Apple has created its reduced version of Mini DVI.

HDMI (High Definition Multimedia Interface) - This is a new high-resolution multimedia interface that appeared on the digital device market in 2003.

He also has a DVI, there is a reduced version that carries the name Mini HDMI.

DisplayPort (DP) - it's this moment most the new kind Connectors, which was developed in 2006. It is a replacement for the DVI standard, even though it is a nuthless simple task, as it may seem. The main distinguishing feature this interface It is that it supports the ability to simultaneously connect several monitors that are consistently connected to the same system.

Sometimes with the DisplayPort connector you can see such an inscription as "DP ++", meaning that if you use adapters, you can easily connect monitors with interfaces such as HDMI or DVI.

Good day, honorable users! To date, I want to talk about the methods of connecting the monitor to the video card - about the connectors of video cards. Modern has no one in stock, but at once several ports for connecting so that it is possible to connect more than 1st monitor immediately. Among these ports, there is both ancient and now rarely used and modern.

VGA Output (D-Sub)

The abbreviation of VGA is decrypted as Video Graphics Array (an array of pixels) or Video Graphics Adapter (video adapter). Appeared in the distant 1987, 15-pin and, as a rule, blue, is designed for output strictly analog signalFor the quality of which, as you know, can affect many different factors (the length of the wire, for example), including the RAMDAC on the video card itself, so that the image quality through this port can be somewhat different in different vidayushki.

Until the widespread distribution of LCD monitors, this connector was almost the only one possible options Connecting the monitor to the computer. It is also used now, but only in low-resolution monitors budget models, as well as in projectors and some gaming consoles, for example in the Xbox consoles of the last generation from Microsoft. It is not recommended to connect a Full HD monitor through it, because the image will be lubricated and fuzzy. Maximum length VGA cable With a resolution of 1600 x 1200 is 5 meters.

DVI (Variations: DVI-I, DVI-A and DVI-D)

Used to transmit a digital signal, changed VGA. Used to connect high-resolution monitors, telec. In, as well as modern digital projectors and plasma panels. The maximum cable length is 10 meters.

The higher the image resolution, the shorter it can be transmitted without loss of quality (without the use of special equipment).

There are 3 types of DVI ports: DVI-D (digital), DVI-A (analog) and DVI-I (combined):

DVI-D.

Only digital connection, makes it possible to avoid losses as an image (especially noticeable at high permissions). Provides incompatible image output due to the fact that the video signal does not pass a double analog / digital conversion, and is transmitted directly in digital form as it is.

DVI-A.

An extremely rare type of analog connection via a DVI port, which in essence is no different from VGA. In nature, practically does not occur.

DVI-I.

Universal, combines two previous species at once. Basically, in modern Vidyushki, it is no longer possible to meet the VGA port, but there are DVI-I on all. Having a specialized adapter to this port, you can connect the VGA monitor.

To transmit digital data, either Single-Link format is used or Dual-Link. Single-Link uses one TMDS transmitter, and Dual-Link doubles throughput And makes it possible to obtain screen resolutions higher than 1920 x 1200, for example 2560? 1600. So for large large-resolution monitors, or a stereo-circuit designed to output, of course, you need at least a DVI Dual-Link, or version 1.3 (about it just below).

HDMI

Also digital output. The main difference from the DVI is that HDMI, in addition to transmitting the video signal, can transmit multichannel digital audio signal. Sound and visual information is transmitted by one cable immediately. Initially, the Movie and Cinema was developed, and later received a wide popularity of PC users. It has backward compatibility with DVI through a special adapter. Maximum length normal HDMI cable - up to 5 meters.

HDMI is another attempt to standardize a universal connection for digital audio and video applications, so that he immediately received powerful support from the giants of electronics (companies contributed to the development such as Sony, Hitachi, Panasonic, Toshib, Thomson, Philips, and as a result - most modern devices To output high-resolution images have at least one HDMI output.

In addition, HDMI, as well, and DVI, allows you to transfer sound-protected sound and a digital view from a single cable using HDCP. Only for the implementation of this technology will require a video card and monitor, attention! - Supports this technology, about how. Again, currently there are several HDMI versions, here's briefly about them:

HDMI 1.3 - Standard of the first version (1.0) had a capacity of 5 Gb / s, whereas in version 1.3 channel expanded to 10.2 Gbps. Also, it was also increased that synchronization up to 340 MHz, which made it possible to connect high-resolution displays with a large number of colors. At the moment it became possible to transfer compressed sound without losses as due to the new Dolby standards. And since the version 1.3, MINI-HDMI appeared, which is currently widely used on video cards.

The arrival of HDMI 1.4 appeared support for stereo imagery (3D), 4K and 2K permissions (3840? 2160 and 4096? 2160 - respectively). Micro-HDMI was developed for miniature devices. A distinctive feature of exactly version 1.4 was the possibility of creating an Ethernet connection at a speed of up to 100 Mbps - and all this one and the same HDMI cable.

Of the distinctive features of the standard HDMI 2.0, it is possible to highlight: increased bandwidth up to 18 Gbps, which, for example, allows you to transfer Full HD 3D with a speed of 120 frames per second; Increased frequent. Audio transmitted to 1536 kHz for the highest sound quality; Added support for monitors and televisions with the aspect ratio of 21: 9.

DisplayPort.

It appeared in addition to DVI and HDMI, since Single-Link DVI can transmit a signal with a resolution to 1920? 1080, and Dual-Link is a maximum up to 2560? 1600, then permission in 3840? 2400 for DVI is not available. The maximum possibilities for permission from DisplayPort do not particularly differ from the same HDMI - 3840 x 2160, however, he still has non-obvious advantages. One of these is, for example, the fact that the use of DisplayPort companies in their devices will not have to pay tax - which, by the way, of course, if it comes to HDMI.

In the photo with red arrows, retainers are marked, which do not allow the connector by chance fall out of the connector. In HDMI, even version 2.0 no fixators are provided.

As you already understood, the main competitor of DisplayPort is HDMI. DisplayPort has an alternative to the technology of protecting the transmitted data from theft, only it is called a little differently - DPCP (DisplayPort Content Protection). In DisplayPort, just like HDMI has support for 3D image, sound content transmission. But, the transmission of the audio signal to DisplayPort is only unilaterally available. And transfer Ethernet data By DisplayPort is generally impossible.

In favor of DisplayPort plays the fact that it has adapters to all popular outputs, such as: DVI, HDMI, VGA (importantly). For example, with HDMI there is only one adapter - on DVI. That is, having only one DisplayPort connector on the video card you can connect the old monitor with one VGA input.

By the way, it is done - now more and more video cards are produced at all without a VGA exit. The maximum length of the usual displayport cable can be up to 15 meters. But its own maximum resolution DisplayPort can transmit no more than 3 meters away - often enough to connect the monitor and video card.

S-Video (TV / OUT)

At the old Vidyushki, sometimes the S-Video connector is encountered, or, as it is also called - S-VHS. It is mainly used to output an analog signal to ancient telelands, however, by the quality of the transmitted image, it is inferior to a more common VGA. When using a high-quality cable through a S-Video image is transmitted without interference to a range of up to 20 meters. Currently, it is extremely rare (on video cards).

Hello, dear readers! Today I would like to talk about the methods of connecting the monitor to the video card - about the connectors of video cards. Modern video cards have no one in stock, but at once several ports for connecting so that it is possible to connect more than one monitor simultaneously. Among these ports, there is both outdated and now rarely used and modern.

The abbreviation of VGA is decrypted as Video Graphics Array (an array of pixels) or Video Graphics Adapter (video adapter). Appeared in the distant 1987, 15-pin and, as a rule, blue, is intended for outputting a strict analog signal, on the quality of which, as is known, many different factors can affect (wire length, for example), including on the video card itself, Therefore, the quality of the picture through this port on different video cards may differ slightly.

Before the widespread distribution of LCD monitors, this connector was almost the only possible options for connecting the monitor to the computer. It is used to this day, but only in low-resolution monitors budget models, as well as in projectors and some gaming consoles, such as the Xbox consoles of the last generation from Microsoft. It is not recommended to connect a Full HD monitor through it, since the picture will be lubricated and fuzzy. The maximum length of the cable VGA at a resolution of 1600 x 1200 is 5 meters.

DVI (Variations: DVI-I, DVI-A and DVI-D)

Used to transfer the digital signal, came to the VGA change. It is used to connect high-resolution monitors, televisions, as well as modern digital projectors and plasma panels. The maximum cable length is 10 meters.

The higher the resolution of the picture, the more to the smaller distance you can pass without loss of quality (without the use of special equipment).

There are three types of DVI ports: DVI-D (digital), DVI-A (analog) and DVI-I (combined):

To transmit digital data, either Single-Link format is used or Dual-Link. Single-Link DVI uses one TMDS transmitter, and Dual-Link doubles bandwidth and allows you to obtain screen resolutions higher than 1920 x 1200, for example 2560 × 1600. Therefore, for large monitors with a large resolution or intended for the withdrawal stereo-circuit, it is necessarily needed at least DVI Dual-Link, or HDMI version 1.3 (about it is slightly lower).

HDMI

Also digital output. The main difference from the DVI is that HDMI, in addition to transmitting a video signal, is able to transmit multichannel digital audio. Sound and visual information is transmitted by one cable at the same time. It was originally developed for television and cinema, and later received the wide popularity of PC users. It has backward compatibility with DVI through a special adapter. The maximum length of the usual HDMI cable is up to 5 meters.

HDMI is another attempt to standardize a universal connection for digital audio and video applications, so it immediately received powerful support from the giants of electronics (companies contributed to the development such as Sony, Hitachi, Panasonic, Toshiba, Thomson, Philips, and As a result, most modern devices for outputting high-resolution images have at least one HDMI output.

Among other things, HDMI, as well, and DVI, allows you to transfer sound-protected sound and the image in digital form by one cable using HDCP. True, a video card and monitor will be needed to implement this technology! - Supports this technology, about how. Again, currently there are several HDMI versions, here's briefly about them:

DisplayPort.

It appeared in addition to DVI and HDMI, since Single-Link DVI can transmit a signal with a resolution to 1920 × 1080, and Dual-Link is a maximum of up to 2560 × 1600, then the resolution is 3840 × 2400 for DVI is not available. The maximum possibilities for permission from DisplayPort do not particularly differ from the same HDMI - 3840 x 2160, however, he still has non-obvious advantages. One of these is, for example, the fact that the use in its devices DisplayPort companies do not have to pay tax - which, by the way, must, if it comes to HDMI.

In the photo of the red arrows marked the clamps that do not allow the connector by chance fall out of the connector. In HDMI, even version 2.0 no fixators are provided.

As you already understood, the main competitor of DisplayPort is HDMI. DisplayPort has an alternative to the technology of protecting the transmitted data from theft, only it is called a little differently - DPCP (DisplayPort Content Protection). In DisplayPort, just like HDMI has support for 3D image, sound content transmission. However, the transmission of the audio signal to DisplayPort is only unilaterally available. And the transmission of Ethernet data on DisplayPort is not possible.

By the way, it happens - now more and more video cards are produced at all without a VGA exit. The maximum length of the usual displayport cable can be up to 15 meters. But the maximum permission of DisplayPort can transmit no more than 3 meters away - often enough to connect the monitor and the video card.

S-Video (TV / OUT)

On old video cards, the S-Video connector is sometimes encountered, or, as it is also called - S-VHS. It is usually used to output an analog signal to outdated televisions, however, by the quality of the transmitted image, it is inferior to a more common VGA. When using a high-quality cable through a S-Video image is transmitted without interference to a range of up to 20 meters. Currently, it is extremely rare (on video cards).

Display a video image on a monitor or TV today different ways - Variants of ports for connecting every year becomes more and more, and it is not wise to get confused in the amount and difference between the interfaces.

We will understand in the most popular formats and we define cases when a particular video port standard is best suited.

VGA

The oldest of the standards of pairing PC and the monitor, which exists to this day. Designed in 1987 by IBM component video interface, uses an analog signal to transmit color information. Unlike more modern standards, VGA does not allow to transmit sound - only a picture.

The VGA connector is usually blue with two screws on the sides. It has a 15-pin connector and initially could work only on a resolution of 640 per 480 pixels using a 16-color palette. Later, the standard developed in the so-called Super VGA, which supports higher screen expansions and the number of colors up to 16 million colors. And since the improved standard continued to use the old port and did not change outwardly, then it is called it in the old manner simply VGA.

Most often, this format is used on the old equipment, but many computers are still equipped with this port. What is called - just in case.

DVI

More than ten years later, after the release of the VGA standard, the light saw the DVI format - a digital video interface. The interface released in 1999 was capable of transmitting video without compression in one of three modes: DVI-I (Integrated) - the combined digital and analog transmission format, DVI-D (Digital) - support for digital signal only, DVI-A (Analog ) - Support only analog signal.

The DVI-I and DVI-D ports can go in single or double mode. In the second case, the bandwidth is doubled, which allows you to obtain a high-definition screen resolution - up to 2048 to 1536 points. However, for this you need to have a corresponding video card. The ports themselves differ in the number of contacts - so single mode (Single Link) uses four twisted pairs of wires (the maximum resolution of 1920 per 1200 pixels at 60 Hz), and the double mode (Dual Link), the corresponding, greater number of contacts and wires (resolution up to 2560 per 1600 at 60 Hz).

It is important to remember that the DVI-A analog version does not support the DVI-D standard monitors, and the video card with DVI-I can be connected to a DVI-D monitor with a cable with two connector DVI-D-fork. By analogy with VGA, this standard also transmits on the screen only video image without sound. However, since 2008, video card manufacturers have made the sound transmission possible - for this you need to use the DVI-D cable - HDMI.

You can also be found on the market and mini-DVI format, invented by Apple, prone to a decrease in everything and all. However, the mini-standard only works in single mode, which means it does not support the expansion higher than 1920 per 1200 pixels.

HDMI

High Definition Multimedia Interface or Interface for High Definition Multimedia Allows you to transmit digital video and audio signals, and also with the ability to protect from copying. HDMI is less than its predecessors in size, works at a higher speed, and most importantly - transfers the sound, which allowed us to retire the former standards of SCART and RCA ("Tulips") for connecting video devices to TVs.

The HDMI 1.0 specification appeared at the end of 2002 and had the maximum bandwidth of 4.9 GB / s, support for the 8-channel audio and video to 165 MPIX / s (that is, FullHD at 60 Hz). Since then, the standard has been constantly developed, and in 2013, the Specification of HDMI 2.0 with a bandwidth of up to 18 Gbit / s, support for the resolution of 4K (3840 per 2160 pixels at 60 Hz) and 32-channel audio.

Today, the HDMI standard uses not only computers, but also digital TVs, DVD and Blu-Ray players, game consoles and many other devices. If you wish, you can use adapters from HDMI to DVI and back.

The number of contacts on HDMI ports starts from 19, and the connectors themselves are available in several form factors, the most common of which are HDMI (Type-A), MINI-HDMI (Type-C), Micro-HDMI (Type D). In addition, there are HDMI ports for receiving a signal (HDMI-IN) and for transmission (HDMI-OUT). Externally, they are almost indistinguishable, but if, say, your monoblock has both ports, then when you try to display a picture to the second monitor, you can use only one of them, and specifically that HDMI-OUT.

DisplayPort.

In 2006, another video station was adopted for digital monitors. DisplayPort, as well as HDMI, transmits not only video, but also audio, and serves to connect a computer with a display or home theater. DisplayPort has more high speed Data transfer, permission support Up to 8k (7680 per 4320 pixels at 60 Hz) in version 1.4, released in March 2016, and a picture through the port can be displayed on several monitors (from two to four, depending on the permission).

DisplayPort was specifically designed to display pictures from computers to monitors, while HDMI was more intended to connect different devices to the TV. However, port data can be used together using the Dual-Mode DisplayPort adapter.

There are also MINI DisplayPort variations that are primarily used in laptops. In particular, the reduced format is loved by Apple.

Thunderbolt.

Finally, the standard from intel companies (for joint work With Apple) to connect the peripheral devices to the computer. It was Apple that was the first one who in 2011 released the device with this interface - laptop MacBook. Pro.

The maximum data transfer rate is 20 Gbps when using fiber for version 2, while the 3rd version of the interface is capable of operating at a speed of up to 40 Gb / s. Thunderbolt combines not only the DisplayPort interface, but also PCI-Express, which means you can connect to it almost whatever. In particular, it is allowed to connect to one port to six devices, which reduces the need to have a huge number of different ports on the device.

The Thunderbolt connector itself is less than that of the mini-displayport, and its third version is at all the port compatible with USB 3.1, that is, is made with a USB Type-C connector.

Universal USB

If you suddenly worry that soon you will have to update all homework due to changing standards, then do not rush. Manufacturers seek to simplify history with numerous interfaces and provide support for old devices through adapters. In particular, only the appropriate adapter will be used for HDMI devices in order to be able to connect to the modern USB Type-C port.

By analogy with the fact that each manufacturer mobile phones It had its own connector for recharging, and now most uses the Micro-USB port, the video station also strives for unification. And the USB port of the last generation, on which both monitors and ordinary headphones and headphones will be connected to the unifying form factor.

In this article, we will tell you in detail about the DVI connector, which can be found in many monitors, TVs and other techniques. A little deeper in the history of this popular interface, and we will also figure it out in its views and features. And still be comparable to a DVI connector with some progressive interfaces. This information will be useful to many users, and will also simplify the process of working with technology and will avoid various difficulties when working.

What is a DVI-output?

A popular connector known as DVI-out (Digital Visual Interface) is intended for high-quality image transmission (video) on various digital type devices. As a rule, these projectors, monitors and televisions.

Developed this video interface DDWG. Often on the Internet you can find decryption of these English letters DVI in the following form - digital video interface. These words are more understandable for many users who are just beginning to recognize the world of computer and the rest of the equipment. This connector has a definite color and form, so that it is quite simple to distinguish from other outputs. Connecting the device to the most different technique is quite simple, without requiring mandatory professional skills and skills.

History DVI Connector

In 1999, Digital Display Working Group officially introduced a completely new standard at the same time on the interface called Digital Visual Interface (DVI). His development was engaged in leading experts from IBM, Intel, Fujitsu and other famous corporations that came to DDWG with one goal - to create a truly innovative interface for transmitting a digital video signal to monitors and other image output tools.

The appearance of DVI marked the Sunset of the VGA era, which for 10 years morally and physically outdated. This allowed not only to improve the quality of the content, but also significantly increase the resolution of the displays. It is noteworthy that DVI connectors are relevant to this day, although now there are serious rivals, which gradually dispense the "veteran".

Features DVI

As for DVI, it uses the data format that is based on Panellink technology. We are talking about the transfer of information that occurs consistently, as well as the originally implemented by Silicon Image. Here the TMDS technology is used when signal transmission occurs differentially to minimize the drops regarding the levels. The activated channels are among the three, the video signal is transmitted at a speed of up to 3.5 Gbps per second. If a cable is up to 10 meters in length, you can send a picture in FHD format (1920 to 1200 points). When a longer connecting cable is used, then the resolution is "trimmed" to the HD format.

In some situations, the DISPLAY DATA Channel (DDC) canal can be activated. With it will be able to convey important information About the display directly to the processor itself, which is installed in the signal source. This includes all the details regarding the characteristics of the device. It is about brand, the date of production, models, size and resolution of the display. The source will consider this information by sending a signal from optimal settings For a specific screen. If the source does not receive the necessary data, then the TMDS channel is possible.

There is support for HDCP, which is an advanced protection system. It is implemented in a more advanced HDMI interface. You can set a variety of content security levels, pushing out your own needs. The basic principle of operation of HDCP - connected using DVI devices exchange passwords with each other. So there is an internal encryption.

It should be noted that the DVI connector is capable of transmitting an exceptionally image. As for sound, it is not transmitted to this case. Therefore, it is necessary to take care of the relevant channels. It is noteworthy that today for certain video cards there are special adapters that make it possible to simultaneously transmit sound and picture.

Types of DVI outputs

The user may encounter several types of outputs. Among them:

DVI-A.
DVI-I (SingleLink)
DVI-I (Duallink)
DVI-D (Singlelin)
DVI-D (Duallink)

Therefore, it is easy to guess that the outlets have certain differences. In addition to the differences in the design, they also have inconsistencies and in features. Often the question is raised in the difference between Single Link and Dual Link. They have a lot of differences. Both options differ from each other with the number of contacts. Double link uses all twenty-four contacts when working. And the single link, which is translated as single, has only eighteen contacts. If the user needs a greater permission, then he is more suitable for the first option. Single Link is suitable for devices that have a resolution of 1920 for 1080. With it, users are becoming much less.

DVI-A Exit

This output assumes only the possibility of analog transmission. An additional letter gives the user to guess that "A" means analog. The connector is a plug in a cable or adapter that allows you to connect video devices (analog) to the output of the DVI-I type.

DVI-I exit

This connector is two types: Single Link and Dual Link. The first option is very in demand and distributed. An additional letter I informs the user that it is integrated. The output is often used for digital displays and video cards. Features of this exit consist in the fact that there are two transmission channels in it. The device combined digital and analog channels. They do not depend on each other, so they do not work at the same time. The task of the device enters on its own, so that it will function. The DUAL LINK connector with the letter I transmits an analog signal. He has as many as two digital channels. This allows the user to achieve much better quality Images and expand your capabilities.

DVI-D output

Here the letter "D" reports on the English Word Digital, which can be translated - digital. In this version there is no analog channel. In this case, only digital transmission occurs. As in previous outputs there is a division into single and double. Single Link will limit the user a little. The permission will not be able to exceed more than 1920 per 1200 (at a frequency of 60 Hz). In this version, only one digital Channel. The user will not be able to connect an analog monitor, as well as rejoice in the technology called NVIDIA 3D Vision. But Dual Link will help look at the 3D monitor, increasing user capabilities. Here are two digital channels.

DVI-I and DVI-D What is the principal difference?
DVI-I supports both digital and analog data transmission, and DVI-D is only digital.

Compatibility DVI connectors

DVI-A will have compatibility only with DVI-A. To transfer an analog signal. As for DVI-D, it provides the transfer of only digital video content. Its compatibility is possible only with DVI-D. Next, you should mention the universal solution that will go for the most different devices. This is about DVI-I. In some cases, you can use adapters. But this is possible only when it is provided by a manufacturer of a device.

The adapter helps solve the problem, but may affect the image quality. Species of these devices are quite a lot. The following are found: DVI - HDMI, VGA - DVI and other sought-after devices. DVI-D cables and DVI-I can work in double mode (dual link). In this case, the bandwidth doubles. For this applies additional contacts. Such a solution makes it possible to transfer much more information, which is favorably reflected at the frequency and image of the monitor, which are becoming higher. If the need to take advantage of NVIDIA 3D Vision technology, then the link is simply necessary necessarily. Also, it is worth knowing that large LCD monitors with great resolution are compatible with the DVI-D Dual-Link connector.

Comparison of DVI connector with HDMI and Display Port

The championship among the connectors is now at DP - Display Port. He changed pretty fast previous developments. It has excellent bandwidth, as well as the user gets much more than new features. The device allows not to lose as, and also stands out in small sizes. He has already started to force out DVI and HDMI. However, not all monitors have exactly the connectors that would come to this novelty.

While there will be changes in the system of their production, you will have to wait for quite a long time. Most manufacturers are in no hurry to use this device for their technology. Therefore, even in many modern and popular models, do not meet DP. Therefore, DVI and HDMI are not yet lost. The last option is perfectly coping with the transfer of digital video along with sound. The device can be found in popular and new models of technology. This interface will help get a high resolution. Each year there are improved versions that have not only excellent bandwidth, but also give the user much more opportunities. Sound and videos do not deteriorate in quality even at a cable length of 10 meters. DVI connector also remains known and in demand. It can be found on many devices, as manufacturers prefer to give it their preference due to its versatility.
