It can be. I have a heap of them in my irrigation system. You need to state what kind of interface you are asking about.
You don't need any special system. You can watch Netflix movies on a normal computer.
An example of a device driver would be the interface between the Windows Operating System and the computers Network Interface Card. Device drivers are used to eliminate the need for the Operating System to know how to "talk" with a given device. The Operating System makes standard calls (called API calls) which are intercepted by the device driver, translated into something the device can understand and passed to the device.
You dont need any interface. PtoTools 9 runs on any audio device, including the built-in sound in you computer.
Besides the cables themselves, each device needs a NIC interface card, and if the computers are on separate networks you need a router. Within a network you would also need a hub, switch, or bridge device.
First you need an interface between two media, second you need that interface to be at an angle to the light path.
You may need both.
Consult the device programmer's manual. Typically you will need an Application Programming Interface (API) suitable for the device in question. The appropriate API should be freely available from the device manufacturer.
You can stream Netflix on iPhone 5 with the app installed. But If you are running the version below ios9, you can't. Because Netflix only supports the ios 9 or later. The other way to stream Netflix on iPhone 5 is to use a downloading tool, such as NoteBurner Netflix Video Downloader. NoteBurner Netflix Video Downloader allows you to download the Netflix video in MP4 format, that you can transfer it to any device for watching.
So the link between the processor and the peripheral is complete :-)!
You need some sort of interface and a computer in between first.
If you want to download movies or TV shows from Netflix, you should install the Netflix app on your device. Open the app and log in with your Netflix account, then find the video that you want to download and click the download icon if capable. All videos downloaded from the app will be remained on your device temporarily. If you want to store the download videos forever, you need the help of a tool, like TunePat Netflix Video Downloader, which can help you download Netflix movies and TV shows in MP4 and MKV format, enables you to watch Netflix videos offline at any time. Netflix videos won't disappear after downloading, and you can move them to other devices freely.
