What is the difference between latch and buffer?

Latch A latch remembers the last state it was told to with another latchingsignal Buffer A buffer merely strengthens a signal so that it canbe fanned out with integrity or drive a heftier device. Any amplifieris a buffer. It outputs a state only as long as the state persistson its input(s).


What do you mean by buffer in micro processor?

A buffer is merely a temporary storage used in conjunction with computation.


What is the use of buffer circuit?

One prominent application is this: Some circuits have an output impedance very high. If these circuits are coupled with another circuit of low input impedance, the desired functionality of the latter circuit will be drastically affected. Because the first circuit tries to deliver large voltage to the second and the second invariably requires small input voltage. To avoid the circuit disfunctionality, a buffer circuit (a circuit with high i/p impedance and a low o/p impedance) is used. Another application is in the delay matching. This is an advanced topic though. The technology is still new. In delay matching, the latter circuit requires a delay of say "n" seconds after the first circuit's output. A buffer circuit is used in such cases also. The circuit design is totally different than the impedance matching case.


What is the function on endl in c plus plus?

std::endl means end line, and is typically used to insert a new-line character in an output stream using the insertion operator (<<). This is really no different to inserting the '\n' character code to the output stream, however it also serves to flush the output buffer by writing all unwritten characters to the output stream. When used as a global function, std:endl(ostream& OS) can be used to insert a new-line character and flush the given output stream. The return value is a reference to the output stream itself thus it can be used in compound statements that make use of the return value.


Why gets function gives a warning every time you compile a c program?

It is unsafe. In order to use gets() safely, you need to know how many characters you will be reading to ensure your character buffer is large enough: char buffer[10]; while (gets (buffer) != 0) { ...process buffer... } The above code has undefined behaviour when the number of characters read is 10 or more (you need one character for the null-terminator). This is because the character buffer, str, decays to a pointer (referencing &str[0]) and the function, gets(), cannot determine the number of characters in a buffer by its pointer alone. The gets() function was dropped from the C standard in 2011, however some implementations still include it. To avoid the warning, use the fgets() function instead. This allows you to specify the length of your buffer and (when used correctly) prevents buffer overflow. char buffer[10]; while (fgets (buffer, 10, stdin) != 0) { ...process buffer... }

Why a latch is used for an output port but a tri-state buffer can be used for an input port?

Is a drive a input or an output?

A drive, whether a hard disk disk, flash memory drive, or floppy disk drive is a peripheral device that can be used for both input and output. This is in contrast to certain devices that can be used for only for output like monitors (non touch screen) and devices which can only be used for input like keyboards.


Why is a common collector amplifier is called buffer?

Since its input impedance is much higher than its output impedance it is also termed a "BUFFER" for this reason it is also used in digital circuits with basic gates...


What is buffer amplifier and its applications?

A buffer amplifier is a type of operational amplifier that amplifies your input signal with a gain of 1 (so your output will be identical to your input, voltage-wise). Buffer amplifiers are used commonly due to having a very high input impedance. This means that loading effects (external factors that your circuit has to deal with) like large currents that could mess with your circuit otherwise, are avoided. A buffer amplifier is often used as the first stage of a circuit because it effectively isolates your circuit from loading effects.
