A virtual device driver (VxD) is a software device driver that emulates hardware and other devices so that multiple applications running in protected mode can access hardware interrupt channels, hardware resources and memory without causing conflicts. The Vxd was superseded by the Windows Driver Model (WDM) and is now obsolete.
H.324 is a telecom standard from the International Telecommunication Standardization Sector or ITU - T. This system for analog phone lines helps to promote consistency in voice, video and data transfer.
H.324, which is also called the terminal for low bit rate multimedia communication, governs the use of systems that operate over the General Switched Telephone Network (GSTN) or Public Switched Telephone Network (PSTN). This is the aggregate infrastructure for the traditional landline communications that were the primary means of telecommunication up until the past several dozen years. As new wireless models have emerged and largely taken over, agencies are still setting standards for analog networks.
Using items like the V.80 protocol, H.324 provides consistent standards for how modems will handle audio and video data. These standards promote more consistent functionality within larger networks and more reliability throughout a networked system.
