- pulse code modulation
Short for pulse code modulation, a sampling technique for digitizing analog signals, especially audio signals. PCM samples the signal 8000 times a second; each sample is represented by 8 bits for a total of 64 Kbps. There are two standards for coding the sample level. The Mu-Law standard is used in North America and Japan […]
- Pulsing Zombie
A form of DoS attack known as a degradation-of-service attack, as opposed to a denial-of-service attack. Unlike a regular zombie that paralyzes a system by inundating it with a steady stream of attack traffic, the pulsing zombie attacks with irregular small bursts of attack traffic from multiple sources on a single target over an extended […]
