Time to live (TTL) or hop limit is a mechanism which limits the lifespan or lifetime of data in a computer or network. TTL may be implemented as a counter or timestamp attached to or embedded in the data. Once the prescribed event count or timespan has elapsed, data is discarded or revalidated.
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
The light returning through the lens is measured and this value is used to calculate the amount of light necessary for the actual exposure. Multiple pre-flashes can be used to improve the flash output. Canon referred to this as Evaluative TTL (E-TTL) and later improved the system with E-TTL II. The first form of digital TTL by Nikon, called "D ...
In the early 1990s, V.32 modems operating at 9,600 bit/s were introduced, but were expensive and were only starting to enter the market when V.32bis was standardized, which operated at 14,400 bit/s. Rockwell International 's chip division developed a new driver chip set incorporating the V.32bis standard and aggressively priced it.

The Federal Reserve announced another cut to its benchmark interest rates yesterday, dropping the Fed rate by 25 basis points to a range of 4.25% to 4.50% — the third consecutive time it's ...
PPS signals are usually generated as a TTL signal capable of driving a 1-kiloohm load. Some sources use line drivers in order to be capable of driving 50-ohm transmission lines. Because of the broad frequency contents, along the transmission line can have a significant impact on the shape of the PPS signal due to dispersion and after delivery ...
