Roles of memory in computer proccessing of data?
Memory hold data that is been processed by the computer Memory also holds data that is waiting to be processed by the computer It also holds data that has been processed by the computer
What memory holds data and instructions as the CPU processes them?
memory
What is the name of the memory chips that holds data temporarily?
Random Access Memory
What is the function of data?
holds 16 bit data just fetched from the memory
How mar and mdr work?
MAR (Memory Address Register) holds the address of the memory location to be accessed or written to in the memory unit, whereas MDR (Memory Data Register) holds the actual data that is to be written to a memory location or data read from a memory location. MAR is used to specify the address, while MDR is used to temporarily store the data during memory operations.
What is data segment memory and code segment memory?
Code Segment, in which all the application code is stored Data Segment, that holds the global data
What is the function of Data Register?
holds 16 bit data just fetched from the memory
RAM that holds data and instructions that the memory controller anticipates the processor will need next?
memory cache
Which area of the computer holds the data and instruction that are about to be used by the central processing unit?
MAIN MEMORY
What is the definition of fetch cycle?
Fetch cycle is defined as a part of instruction cycle in which data is fetched from the memory pointed by Holds the address of a memory block to be read from or written to) and stores the data in MDR( a two-way register that holds data fetched from memory (and ready for the CPU to process) or data waiting to be stored in memory) for further processing. Instruction cycle= Fetch cycle+ Execute cycle
What is computer circuitry that temporarily holds data waiting to processed known as?
The Ram - Random Access Memory temporarily holds programs and data while the computer is on and allows the computer to access that information randomly.
How do the contents of the MAR and MDR registers changes during the fetch decode execute cycle?
During the fetch-decode-execute cycle, the Memory Address Register (MAR) holds the address of the memory location from which data is to be fetched or to which data is to be written. In the fetch phase, the MAR is loaded with the address of the next instruction to be executed. The Memory Data Register (MDR) then temporarily holds the data fetched from memory or the data to be written to memory. As the cycle progresses, the contents of the MAR and MDR are updated based on the memory operations required for executing the instruction.
