The TTL circuit is the abbreviation for transistor-transistor logic circuit (transister-transister-logic), which is a digital integrated electricalA wide range of roads. It is manufactured with a bipolar process and features high speed, low power consumption and variety.CMOS is: A metal-oxide-semiconductor (metal-oxide-semiconductor) structure of transistors referred to as MOS transistors,There are P-type MOS tubes and N-Type MOS tubes. An integrated
What is TTL level?
TTL-level signals are used most often because they are represented in binary format. + 5 V is equivalent to logic "1" and 0 V is equivalent to logic "0 ", this is called a TTL (transistor-Transistor Logic level) Signal System, which is a standard technology for communication between various components of a device controlled by a computer proces

The specific meaning of TTL in Ping Command
In short, TTL is the full time to live, which means the life cycle.The ping command uses the network layer protocol ICMP. Therefore, TTL refers to the lifecycle of a network layer packet (package, if you do not understand this sentence, go back and review the osi7 protocol.The first question is why we

TTL is a value in the IP protocol package. It tells the network whether the packet is discarded because the time in the network is too long. There are many reasons that the package cannot be delivered to the destination within a certain period of time. The solution is to discard the packet after a period of time and then send the packet to the sender, which determines whether to resend the packet. The initial value of

TTL:(Time to live) life time is a value in the IP protocol package. It tells the network router package whether the time in the network is too long and should be discarded. There are many reasons that the package cannot be delivered to the destination within a certain period of time. For example, an incorrect route table may cause an infinite loop of packets. One solution is to discard the packet after a period of time and then send a message to the s
Differences between TTL level and RS232 level
?
When I encountered a problem about the level selection, I forgot the definition of the RS232 level. At that time, I was unable to respond. After I came back, I found out the difference between the two, it may take more than two years for you to forget some common sense that you were familiar with before. This is not a good phenomenon. :-), or copy the differences between the three common levels here. it
What do you mean by a TTL?
The TTL is the value of an IP protocol that tells the network whether the packet's time in the network is too long and should be discarded. There are a number of reasons why the package cannot be delivered to the destination for a certain amount of time.
The initial value of the TTL is usually the system default, which is a 8-bit fiel
