Transistor-transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors. It is called transistor-transistor logic because both the logic gating function and the amplifying function are done by transistors.
To know about the advantages of TTL logic family, one should have a basic idea about RTL, DTL etc. Diode logic (DL) uses diodes to implement logical functions like AND and OR. But the disadvantage is that it can not perform NOT operation. As AND and OR are not complete functions by themselves, they can not perform several logic functions without NOT. Hence, there was a need for some device which can perform a NOT function as diodes can not. That device is a transistor. Then came the DTL which uses a transistor along with diodes. As a transistor can act as an inverter, NAND (NOT-AND) & NOR (NOT-OR) operations can be performed. But this logic uses several diodes which will slow down its operation. Due to the delay offered by them, the logic levels may sometimes change i. e. 0 t0 1 or 1 to 0. Then came TTL. This logic uses a multi emitter transistor, a transistor with many emitter terminals. As every emitter is nothing but a diode, this logic eliminates the use of all diodes. This is the major advantage. As transistor becomes ON and OFF much rapidly than a diode, switching time will be faster.
TTL, or Transistor-transistor logic replaced resistor-transistor logic, and used much less power. The TTL family is very fast and reliable, and newer faster, less power-consuming, etc. types are always being developed.

With a diode tube you have no control over the current flow and it can only be used as a rectifier, where the triode consist of a control grid, to control the flow of electrons that will reach the anode, this make it possible to use the triode as a amplifier, compared to a transistor the control grid have the same function as the base of the transistor.Advantages?Over tetrodes and pentodes:1. Operation at higher radio frequencies,2. Lower noise figures,3. Simpler circuitry and only one power supply.
Transistors need thermal stabilization because the operating point of a transistor junction, similar to a diode, is affected by temperature. In fact, this can cause thermal runaway, and device destruction, if the circuit design does not compensate for this. Answer mostly correct but the operating point of a transistor must remain fixed as temperature varies whether going low or higher. that is mainly the concern about. not runaway that is caused by bad design.
Advantages of self healing robots are: 1. Recover from minor damages 2. Low maintenance cost 3. Adjustable to the environment
There are many different advantages of a microprocessor based system. Some of these include that it only uses 3 components so it is simple to use and install and it will increase your memory.
I will assume you mean "transistors". Compared to their predecessors (vacuum tubes), transistors:* Are faster * Use less current * Use less space Note that all of these advantages get even more pronounced in the case of integrated circuits (which also contain transistors).
There are a variety of different advantages of 4 wheelers over 3 wheelers in terms of vehicles. Some of these advantages are that 4 wheelers are much safer than 3 wheelers.
1. A transistor *is* a triode- this is the general name for any three-electrode electronic device. 2. Most people understand "triode" to mean a tride vacuum tube/valve. 3. The transistor (i) needs no heated filament/cathode, so it uses much less power than a valve triode, (ii) because of (i), transistors do not "burn out" with age, so they have much longer lifetimes, are much more reliable, and generate much less waste heat, (iii) transistors can operate at much lower power than triode valves, and at much higher frequencies, (iv) transistors can be made much smaller than triodes, by a factor of many tens of thousands, (v) from early on, transistors were much cheaper than triode valves.
