  • high-level data link control — (networking)   (HDLC) A general-purpose data link control protocol defined by ISO for use on both point-to-point and multipoint (multidrop) data links. It supports full-duplex, transparent-mode operation. It is used extensively in both multipoint and computer networks. Some manufacturers and other standards bodies still use their own acronyms, e.g. IBM's SDLC (Synchronous Data Link Control), the forerunner of HDLC and ANSI's ADCCP (Advanced Data Communications Control Procedure).
  • hot standby routing protocol — (protocol)   (HSRP) A CISCO standard, defined in RFC 2281, that calls for a mirrored router in passive mode to send hello packets, wait for a lead router to die and, without dropping a packet, take over from that router. Note: "standby", not "swappable" (and certainly not "swapable").
  • human chorionic gonadotropin — chorionic gonadotropin (def 1). Abbreviation: hCG.
  • hydrolysed vegetable protein — a powder or liquid that is produced by boiling legumes or cereals in hydrochloric acid and then neutralizing with sodium hydroxide. It is used as a flavouring in some foods, such as soups and bouillon cubes

  • ieee floating point standard — (standard, mathematics)   (IEEE 754) "IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std 754-1985)" or IEC 559: "Binary floating-point arithmetic for microprocessor systems". A standard, used by many CPUs and FPUs, which defines formats for representing floating-point numbers; representations of special values (e.g. infinity, very small values, NaN); five exceptions, when they occur, and what happens when they do occur; four rounding modes; and a set of floating-point operations that will work identically on any conforming system. IEEE 754 specifies formats for representing floating-point values: single-precision (32-bit) is required, double-precision (64-bit) is optional. The standard also mentions that some implementations may include single-extended precision (80-bit) and double-extended precision (128-bit) formats.

  • multimedia personal computer — (multimedia)   (MPC) A specification published by the Multimedia PC Marketing Council in 1990 to encourage the adoption of a standard multimedia computing platform. In May 1993, the MPC Marketing Council published a new specification called MPC Level 2 Specification as an enhanced multimedia computer standard. The original MPC specification, now also known as the MPC Level 1 Specification, continues in full effect. The appearance of the MPC or MPC2 certification mark on a computer system or upgrade kit indicates that the hardware meets the corresponding (Level 1 or Level 2) MPC Marketing Council specification. Software bearing the Multimedia PC mark has been designed to work on Multimedia PC licensed hardware. By establishing a standard platform, certifying hardware compliance and providing inter-operability between software and hardware for the consumer, the MPC Marketing Council is encouraging widespread use of multimedia applications and hardware.

  • radio frequency interference — (hardware, testing)   (RFI) Electromagnetic radiation which is emitted by electrical circuits carrying rapidly changing signals, as a by-product of their normal operation, and which causes unwanted signals (interference or noise) to be induced in other circuits. The most important means of reducing RFI are: use of bypass or "decoupling" capacitors on each active device (connected across the power supply, as close to the device as possible), risetime control of high speed signals using series resistors and VCC filtering. Shielding is usually a last resort after other techniques have failed because of the added expense of RF gaskets and the like. The efficiency of the radiation is dependent on the height above the ground or power plane (at RF one is as good as the other) and the length of the conductor in relationship to the wavelength of the signal component (fundamental, harmonic or transient (overshoot, undershoot or ringing)). At lower frequencies, such as 133 MHz, radiation is almost exclusively via I/O cables; RF noise gets onto the power planes and is coupled to the line drivers via the VCC and ground pins. The Rf is then coupled to the cable through the line driver as common node noise. Since the noise is common mode, shielding has very little effect, even with differential pairs. The RF energy is capacitively coupled from the signal pair to the shield and the shield itself does the radiating. At higher frequencies, usually above 500 Mhz, traces get electrically longer and higher above the plane. Two techniques are used at these frequencies: wave shaping with series resistors and embedding the traces between the two planes. If all these measures still leave too much RFI, sheilding such as RF gaskets and copper tape can be used. Most digital equipment is designed with metal, or coated plastic, cases. Switching power supplies can be a source of RFI, but have become less of a problem as design techniques have improved. Most countries have legal requirements that electronic and electrical hardware must still work correctly when subjected to certain amounts of RFI, and should not emit RFI which could interfere with other equipment (such as radios).
