Why a latch is used for an output port but a tri-state buffer can be used for an input port?
The Latch will hold the data until new data will changes from input of Buffer.
What is an address buffer and a data buffer?
The contents of the stack pointer and program counter are loaded into the address buffer and address-data buffer. These buffers are then used to drive the external address bus and address-data bus. As the memory and I/O chips are connected to these buses, the CPU can exchange desired data to the memory and I/O chips. The address-data buffer is not only connected to the external data bus but also to the internal data bus which consists of 8-bits. The address data buffer can both send and receive data from internal data bus.
Why scanf functions is not used to read a line of text?
Because it is not safe. Scanf puts the data into a buffer. There is no size checking so the data may be larger than the buffer causing a buffer overrun with undefined (usually bad but always undesirable) behavior.
What is buffer in c?
A buffer is a (usually temporary) place to store data. If you have a data stream that needs to be processed, it will usually be placed into a buffer and then read from the buffer, rather than trying to read the stream directly.
What is bounded buffer problem?
The problem has to do with two processes, the producer and the consumer, who share a common, fixed-size buffer. The producer's job is to generate a piece of data, put it into the buffer and start again. At the same time the consumer is consuming the data (i.e. removing it from the buffer) one piece at a time. The problem is to make sure that the producer won't try to add data into the buffer if it's full and that the consumer won't try to remove data from an empty buffer

What is the purpose of buffer register?
here, just the registers are used to store the temporary data in the variables instead of RAM.
How frame buffer can be used to control the color and intensity of the picture display?
The data from the framebuffer determines which of the colors in the palette are used for the current pixel it is rendering. This output data provides primary-color data from the lookup table.
What can trigger a buffer overflow?
A buffer overflow occurs when a program attempts to write data to a buffer, but exceeds the boundaries of the buffer, similar to Java's "Array Out of Bounds Exception." This could happen with poorly written code that fails to check for the end of the buffer, or it could be exploited maliciously. One exploitative example would be a stack buffer overflow, in which data is copied to a local variable on the stack. But if the data is larger than the local variable can contain, the extra data will "spill over" onto nearby memory. This would allow one to overwrite data that was not intended to be altered.
What is the difference between data communication and data communication information2010to2013?
The scope of work and the educational requirements are the difference between data communication and data communication information.
What is a data communication link?
data communication link
Why are large buffer useful in a printer?
A buffer helps to hold data to be printer first when the printer is busy. It also has a limit to how much data it can hold. Thus with a bigger buffer space, the buffer can hold more files or bigger size. This also means that more data can be stored in the buffer at one go without having to make too many changes to it (eg. deleting the tasks).
