Hardware Questions

stack is portion of RAM used for saving the content of Program Counter and general purpose registers.

LIFO stacks, also known as "push down" stacks, are the conceptually simplest way of saving information in a temporary storage location for such common computer operations as mathematical expression evaluation and recursive subroutine calling.

Yes, it can be used, if an accurate clock frequency  is not required. also the component cost is low compared to LC or Crystal.

Code, Data, Stack, Extra Segment registers in 8086.

In case of Move A to B it will move whatever the value of A into B.It mean it will move numeric, alphanumeric and alphabatic value.

In case of COMPUTE B=A it will assign the value of A into B. But in case of compute only numeric value will be compute.

An interrupt which can be never be turned off (ie. disabled) is known as Non-Maskable interrupt

Cache momory is a small high-speed memory. it is used for temporary storage of data & information between the main memory and the CPU(center processing unit). The cache memory is only in RAM.

Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. AS the microprocessor processes data, it looks in the cache memory and if it finds the data there.

3MHz is the maximum clock frequency for 8085.

There are 12 interrupts in 8085.
