10 Questions
What is the key concept of the von Neumann architecture related to memory storage?
Data and instructions are stored in a single read-write memory
What is the purpose of the Memory Address Register (MAR) in a computer system?
Specifies the address in memory for the next read or write
What does the I/O Buffer Register (I/OBR) do in a computer system?
Contains the data to be written into memory or receives the data read from memory
What happens at the beginning of each instruction cycle in a computer system?
The processor fetches an instruction from memory
Why is the width of the data bus considered a key factor in determining overall system performance?
It affects the number of bits that can be transferred at a time
What is the purpose of the Instruction Register (IR) in a computer system?
Interprets the instruction fetched from memory
What distinguishes a System Bus from other communication lines in a computer system?
It connects major computer components like processor, memory, and I/O
What does the Program Counter (PC) hold in a computer system?
The address of the next instruction to be fetched
In what scenario is direct memory access (DMA) used in a computer system?
To enable an I/O module to read or write directly to memory
