TTL in the ISO/OSI Stack (IP Networks)
=======================
TTL (Time To Live) is the time a message has to live given in hops. Each time the package is forwarded this counter counts down.
With the TTL one avoids a datagram being routed in circles and cloaking the "intertube"'s up.

TTL
A line driver is a device designed to transmit signals over long distances, providing higher voltage levels and current to ensure signal integrity, particularly in noisy environments. In contrast, TTL (Transistor-Transistor Logic) refers to a specific type of digital logic circuit that uses bipolar junction transistors and resistors to perform logical operations. While TTL can be used as a signal source, it typically operates at lower voltages and is not optimized for long-distance communication like line drivers are. Essentially, line drivers enhance signal transmission capabilities, while TTL focuses on digital logic functionality.
TTL stands for Time To Live
TTL is set to 40
TTL is faster and does not lose amplitude
The full form of TTL is Time To Live
Here are the propagation delays for these gatesa) ECL = 2nsb) TTL = 1.5-33ns depending on the type of TTL. Conventional TTL is 9ns, Advanced Schottky TTL is 1.5nsc) RTL = 25nsd) CMOS = 5-20ns depending on if it is conventional CMOS, TTL pin compatible CMOS, high speed TPC CMOS or TTL compatible CMOSSo the fastest would be the Advanced Schottky TTL (74ASxx) at 1.5ns but the choice simply said TTL which I would interpret as Conventional TTL (74xx/54xx) which would have a propagation delay at 9ns.So the winner is ... (a) ECL which has a propagation delay at 2ns.
The main advantage of ECL over TTL is speed.

Because a TTL determines the maximum number of days the server will TTL of 0 means that the resource record should not be cached.
the ttl compatability is nothing but the time to live factor of a packet in the dns system
