VxD is the device driver model used in Microsoft Windows/386 2.x, the 386 enhanced mode of Windows 3.x, Windows 9x, and to some extent also by the Novell DOS 7, OpenDOS 7.01, and DR-DOS 7.02 (and higher) multitasker (TASKMGR). [1]
The Linear Executable (LE) format is a file format for executables, object code, and DLLs designed for 32-bit protected mode operating systems. Originally used by the OS/2 operating system and adopted by various DOS extenders, it also served as the file format for Virtual Device Drivers (VxD) in early versions of Windows, including Windows 3.x and the Windows 9x series.

Once the real-mode virtual device drivers are loaded, driver initialisation on Windows 95 and 98 occurs. Vmm32 then switches the CPU from real mode to protected mode . The next step is the initialisation of protected mode drivers, executed in three phases for each device: a critical part of initialisation (while interrupts are disabled), device ...

In computer networking, TUN and TAP are kernel virtual network devices. Being network devices supported entirely in software, they differ from ordinary network devices which are backed by physical network adapters. The Universal TUN/TAP Driver originated in 2000 as a merger of the corresponding drivers in Solaris, Linux and BSD. [1]
A software-based virtual serial port presents one or more virtual serial port identifiers on a PC which other applications can see and interact with as if they were real hardware ports, but the data sent and received to these virtual devices is handled by software that manipulates the transmitted and received data to grant greater functionality.
Virtual disk and virtual drive are software components that emulate an actual disk storage device.. Virtual disks and virtual drives are common components of virtual machines in hardware virtualization, but they are also widely used for various purposes unrelated to virtualization, such as for the creation of logical disks,software development, testing environments, and data management.
The Remote Network Driver Interface Specification (RNDIS) is a Microsoft proprietary protocol used mostly on top of USB. [1] It provides a virtual Ethernet link to most versions of the Windows, Linux, and FreeBSD operating systems. Multiple revisions of a partial RNDIS specification are available from Microsoft, but Windows implementations have ...
