Chapter 1 Flashcards
What are real time systems
The systems that are time bound
What is purpose of data bus
Take data to memory and processor. It is bidirectional
What is control bus
A control bus is used by CPU for communicating with other devices within the computer. It is bidirectional.
What is the task of index register
It holds the memory address of data
What is address bus
The group of bits that the processor uses to inform the memory about which element to read or write is collectively known as the address bus. address bus generate binary numbers. It is unidirectional
What is data bus
the data bus is used to move the data from the memory to the processor in a read operation and from the processor to the memory in a write operation.
What is control bus
Precise synchronization between the processor and the memory is the responsibility of the control bus
Is control bus bidirectional
Yes
Is address bus unidirectional
Yes
What is cell width
The number of bits in a cell is called the cell width.
What are registers
There are temporary storage places inside the processor called registers.
