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. In computer networking, TTL prevents a data ...
Country code top-level domain. A country code top-level domain ( ccTLD) is an Internet top-level domain generally used or reserved for a country, sovereign state, or dependent territory identified with a country code. All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs.
This is a TLD for Web sites in the Catalan language or related to Catalan culture. Catalan: Yes .eus: Basque, Spain and France: Euskal Herria in Basque. Web sites must be in the Basque language and are checked periodically. Unknown: Yes .gal Galicia: This is a TLD for Web sites in the Galician language or related to Galician culture. Unknown
A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family. Many logic families were produced as individual components, each containing one or a few related basic ...
For example, every device (such as an intermediate router) forwarding an IP datagram first decrements the time to live (TTL) field in the IP header by one. If the resulting TTL is 0, the packet is discarded and an ICMP time exceeded message is sent to the datagram's source address. Many commonly used network utilities are based on ICMP messages.
Change the outbound TTL to 255 for its protocol connection; If the protocol is a configured protocol peer. Set the Access Control List (ACL) to allow packets of the given protocol to only pass to the route processor (RP). The TTL must be set to either 255 if the destination is directly connect or 255 minus the range of acceptable hops if not ...

Transistor–transistor logic. Transistor–transistor logic ( TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function (the first "transistor") and the amplifying function (the second "transistor"), as opposed to earlier resistor–transistor logic (RTL) and diode ...
