What is Dynamic Memory Access (DMA) ?
What is cache memory ?
A very high speed memory between the RAM/ROM and the CPU.
Cache memory is used to supply the most recently used instructions/data to the CPU.
Cache memory is much faster to access than the RAM/ROM but very costly.
What is Application Programming Interface (API) ?
It is defined by a set of function calls using which applications can be developed over an operating system or a software development tool
What is adress mode and address space ?
Adress mode is defined by the way by which an operand is specified for an instruction.
For example : imediate address mode,direct adressing mode,register addressing etc..
Address space is the maximum memory size that can be addressed by a processor
CPU with 16 address lines can address 2^16 bytes of address space
What is a address bus ?
Address bus is a set of wires using which a processor or a microcontroller communicates with the peripheral to sellect a memory location or a register of a peripheral.
