How do adapters work? (SATA to USB, or VGA to HDMI)

In summary, adapters (exp: SATA to USB or VGA to hdmi) can work with special softwares for conversion, but they are not just electronic circuits that gets and directs input signals to correct output pins.

Does adapters (exp: SATA to USB or VGA to hdmi) work with special softwares for conversion or are they only electronic circuits which gets and directs input signals to correct output pins?

Answering to match the specificity of your question, often elements of both.

In addition to what @Asymptotic said: some adapters are simple rewirings, and others are protocol converters that require intermediary processing. An example of the former is USB 2.0 ##\leftrightarrow## Cat 5 Ethernet cable; an example of the latter is SATA ##\leftrightarrow## USB 3.0.

Some of hese only workone way also. You can get USB to SATA interfaces but it doesn't work the other way around. Likewise HDMI is going to be a digital output, VGA is analogue. You can convert a HDMI signal to an analogue one but you cannot get a VGA to HMDI convertor.

I think you can... And while SATA to general USB won't be found, I wouldn't be suprised to find some pendrive-on-sata type frankenboard, since it is already not a problem to fit some SD-cards into a raid hanging on SATA 😉

USB and SATA are both bidirectional. You can get interfaces to do whatever you want with either of their protocols. Single-chip analog to digital converters, and digital to analog converters, are common components. VGA to HDMI convertors are easily available.

in latter example does it use embeded software or only does this with special circuits?

I assume you're referring to the SATA ##\leftrightarrow## USB 3.0 interface. Typically, none of that would be done at the software level, but some of it might be done as one-time ROM firmware. I don't know the specifics of any particular such device, but you can see from the following image that it does power handling and 'mapping' one set of pins to another, with some small IC chips to manage the bidirectional data flow with conversion, synchronization, and throughput assurance.

Related to How do adapters work? (SATA to USB, or VGA to HDMI)

1. How does a SATA to USB adapter work?

A SATA to USB adapter works by converting the data from a SATA connection to a format that can be read by a USB port. This allows devices with SATA connections, such as hard drives and solid-state drives, to be connected to devices with USB ports, such as computers and laptops.

2. Can a SATA to USB adapter work with any type of SATA drive?

Most SATA to USB adapters are designed to work with both SATA hard drives and solid-state drives. However, it is important to check the specifications of the specific adapter to ensure that it is compatible with the type of SATA drive you want to use.

3. How does a VGA to HDMI adapter work?

A VGA to HDMI adapter works by converting the analog VGA signal from a device, such as a computer, to a digital HDMI signal. This allows the VGA output to be displayed on a device with an HDMI input, such as a TV or monitor.

4. Is a VGA to HDMI adapter bi-directional?

No, a VGA to HDMI adapter is not bi-directional. This means that it can only convert a VGA signal to HDMI, and not the other way around. Therefore, it cannot be used to connect an HDMI device to a VGA display.

5. Can a VGA to HDMI adapter improve the video quality?

No, a VGA to HDMI adapter does not improve the video quality. The quality of the video will depend on the quality of the original signal and the capabilities of the devices being connected. However, using a VGA to HDMI adapter may allow for a higher resolution display if the original VGA signal supports it.
