Bus contention in microprocessors occurs when multiple devices attempt to access the data bus simultaneously, leading to conflicts and potential data corruption. This situation can arise in systems where multiple bus masters, such as CPUs and DMA controllers, compete for control of the bus. To mitigate bus contention, mechanisms like bus arbitration and priority schemes are implemented, ensuring orderly access to the bus. Effective management of bus contention is crucial for maintaining system stability and performance.

What is tristate bus and how it used in microprocessor?
In Microprocessor based system devices are connected n parallel through the bus in this situation it is required that one device is interact with the bus at a time .If more than one device make communication wid bus then more then one signal is places that they will produce damaging current known as Bus Contention.To avoid bus contention tristate buffer are placed between buses and peripheral...
What is an address bus in a microprocessor?
The address bus is a section of the bus that emits the address of the desired instruction or operand.
What is known as 8 bit internal bus?
the bus through which the data are transmitted or received within microprocessor and with peripherals is called as data bus.when used internally to microprocessor called internal data bus.
What do you mean by AD bus in microprocessor?

Why is data bus bidirectional but address bus is unidirectional?
since data can be read /write from/to the microprocessor, hence data bus is bidirectional. if data is required read from microprocessor then it will be pointing to a memory location by the address bus, by indicating which location data its required to read. similarly to write a data to a location, again the microprocessor will be to that particular location by holding that address in address bus. hence it will be unidirectional.
What is bus cycle in a microprocessor?

Which bus is used to synchronise the sending and receiving of data in a microprocessor system?
The bus used to synchronize the sending and receiving of data in a microprocessor system is typically the control bus. It carries control signals from the microprocessor to other components, managing the timing and coordination of data transfers. This ensures that the CPU, memory, and input/output devices communicate effectively and in a timely manner.
What is the function of control bus in references to 8085 microprocessor?
It provides timing signals.
