dB of sound pressure level (dB SPL) is defined as: 20 log10 p1/p0 where p1 is actually measured sound pressure level of a given sound, and p0 is a reference value of 20Î¼Pa, which corresponds to the lowest hearing threshold of the young, healthy ear.
The outside refers to the external-facing network interface, the one that receives ingress traffic. In the real world, it is not the case that NAT is simply using a single outside IP; translating traffic into internal IPs and ports. That's what your Linksys router does. Key Terms To Understanding NAT and PAT: NAT Short for Network Address Translation, an Internet standard that enables a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. PAT Short for port address translation, a type of network address translation.
ATA. Short for Advanced Technology Attachment, ATA was approved May 12, 1994 and is an interface that connects hard drives, CD-ROM drives, and other drives. The first ATA interface is now commonly referred to as PATA, which is short for Parallel AT Attachment after the introduction of SATA.TA-4, ATAPI-4, and ATA/ATAPI-4. ATA-4 is a standard approved by ANSI in 1998 under document NCITS 317-1998.
