Ttl in a sentence

The first router receives the packet, decrements the TTL value and drops the packet because it then has TTL value zero.

The value of the minimum field of the SOA record and the TTL of the SOA itself is used to establish the TTL for the negative answer.

TTL systems usually have a decoupling capacitor for every one or two IC packages, so that a current pulse from one TTL chip does not momentarily reduce the supply voltage to another.

As collaborative agency partners, both businesses have worked together across an array of clients in South Africa including Travelstart and The Courier Guy to offer comprehensive, impactful and data-backed through-the-line (TTL) support to their clients.

A game typically includes 64 to 96 TTL-level inputs from a variety of sensors such as mechanical leaf switches, optical sensors and electromagnetic sensors.

Although they did not contain any microprocessors, but were built around transistor-transistor logic (TTL), Hewlett-Packard calculators as far back as 1968 had various levels of programmability such that could be called microcomputers.

An n-channel MOS integrated circuit could operate two or three times faster and was compatible with TTL.

As a noteworthy consequence of this distributed and caching architecture, changes to DNS records do not propagate throughout the network immediately, but require all caches to expire and refresh after the TTL.

Bipolar transistor-based logic (such as TTL ) does not have such a high fanout capacity.

Common features Cut-away of a Minolta XE film-based SLR Other features found on many SLR cameras include through-the-lens (TTL) metering and sophisticated flash control referred to as "dedicated electronic flash".

Compared to contemporary ECL circuits, TTL uses less power and has easier design rules but is substantially slower.

Designers can combine ECL and TTL devices in the same system to achieve best overall performance and economy, but level-shifting devices are required between the two logic families.

Due to the output structure of TTL devices, the output impedance is asymmetrical between the high and low state, making them unsuitable for driving transmission lines.

Enzymes related to TTL add the initial branching glutamate (TTL4,5 and 7), while other enzymes that belong to the same family lengthen the polyglutamate chain (TTL6,11 and 13).

Even after much larger scale integrated circuits made multiple-circuit-board processors obsolete, TTL devices still found extensive use as the "glue" logic interfacing more densely integrated components.

For example, a 300-second TTL would help key records expire in 5 minutes to help ensure these records are flushed quickly worldwide.

For example, using the TTL levels of near +5 and 0 V puts the mark level in the undefined area of the standard.

For Time to live (TTL) or hop limit is a mechanism that limits the lifespan or lifetime of data in a computer or network.

History A real-time clock built of TTL chips around 1979.

However, a problem persists in that some caching DNS nameservers set their own TTLs regardless of the authoritative records, so it cannot be guaranteed that all downstream DNS servers have the new records after the TTL has expired.
