Short for Hardware Identification, a security measure used by Microsoft upon the activation of the Windows operating system. As part of the Product Activation system, a unique HWID number is generated when the operating system is first installed. The HWID identifies the hardware components that the system is utilizing, and this number is communicated to Microsoft. Every 10 days and at every reboot the operating system will generate another HWID number and compare it to the original to make sure that the operating system is still running on the same device. If the two HWID numbers differ too much then the operating system will shut down until Microsoft reactivates the product.
The theory behind HWID is to ensure that the operating system is not being used on any device other than the one for which it was purchased and registered. However, problems can arise when users start replacing or adding hardware components — such as motherboards, sound cards, CD-R drives, Ethernet adapters — because these will generate new HWIDs, and if there are too many differences from the original installation number the system will register that the operating system has been installed on a different device than the original and subsequently shut itself down. The only way to resolve the issue is to telephone Microsoft and explain the new hardware in order to obtain a new code.
In electronics and audio consumer electronics gain is a unit of measurement used to mean the ratio of a signal output of a system to the signal input of the system. Gain is a term most commonly associated with amplifiers.
Is an H.323 protocol for capability negotiation, messages for opening and closing channels for media streams; for example – media signaling.
An International Telecommunications Union (ITU) standard that provides specification for computers, equipment, and services for multimedia communication over packet based networks that defines how real-time audio, video and data information is transmitted. H.323 is commonly used in VoIP, Internet Telephony, and IP-based videoconferencing. Users can connect with other users over the Internet and use varying […]
A suite of standards approved by the International Telecommunications Union (ITU) that defines videoconferencing over analog (POTS) telephone wires. One of the main components of H.324 is the V.80 protocol that specifies how modems should handle streaming audio and video data.
A high-level programming language commissioned by NASA in the 1970’s. Hal/S is a a real-time aerospace programming language that is most known for use in NASA’s Space Shuttle program. Hal/S is used in the programming of onboard shuttle software. Initially Hal/S was a FORTRAN preprocessor then called Hal that was written in FORTRAN and generated […]
