Computer Memory and Storage

This pool consists of memory area that are shared by multiple users.

Data dictionaries store metadata about data elements including their location, ownership relationships, and usage patterns within the system. They do not contain technical hardware specifications like disk storage device sizes, which are physical storage details outside the scope of data element metadata.

In physical data independence, the changes done on the physical data independence does not affect the logical data independence.

DMA controller is like a special hardware in Direct Memory Access to manage the data transfer.

Yes, all of the above are the uses of the registers in DMA controller.

The Data bus transfers the data to and from the memory or from the CPU to other components of the computer system.

This is true about Memory Data Register.

None of the above options are true according to the question. The Current Instruction Register (CIR) is used to hold the current instruction being executed.

Here, all the major calculations take place in EAX making it similar to a dedicated intex86 accumulator register.

Mnemonic operation codes are used in machine instructions and eliminates the need to memorize numeric operation codes.

It indicates the symbolic mnemonic for each instruction and its length(two, four or six bytes).

It holds the location of current stack frame.

It is a particular kind of unintentional memory consumption by a computer program where the program fails to release memory when no longer needed.

This register is used to store 8 bit data and to perform arithmetic and logical operations in 8085 processor.

This signal appears in a machine cycle to advise the external circuitry that the AD0 -AD7 lines contain the lower 8 bits of a memory address in 8085 processor.
