What is an address in C plus plus programming?
An address in C or C++ is the location in memory of an object or function. An address is the contents of a pointer, as opposed to the contents of the memory location pointed to by the pointer.
What is a variable plus a variable?
A variable is a named memory location for which the contents are volatile. The antonym of variable is constant.
How does the Fetch Decode Execute work?
The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.
How does fetch decode cycle work?
The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.
What is magnetic disk?
RAM:(RANDOM ACCESS MEMORY)RAM is the primary storage device and the data and instructions are stored temporarily in it. It takes the same amount of time to access any location in RAM. CPU can perform two types of operations on Ram, these are:ReadWriteRead operation:during read operation the contents of memory location are copied to a CPU register.Write operation:During write operation the contents of a CPU register are copied to the memory location.

How can you delete the contents of a flash memory internaly?

What is poiner value in c?
In c a pointer is a variable that points to or references a memory location in which data is stored. Each memory cell in the computer has an address that can be used to access that location so a pointer variable points to a memory location we can access and change the contents of this memory location via the pointer. Pointer declaration A pointer is a variable that contains the memory location of another variable. The syntax is as shown below. You start by specifying the type of data stored in the location identified by the pointer. The asterisk tells the compiler that you are creating a pointer variable. Finally you give the name of the variable. type * variable name Example: int *ptr; float *string;
What Memory that loses it contents when system is shut off?
It's called "Volatile Memory".
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.
M- m plus in a calculator?
M- subtracts the value showing from the contents of the memory. M+ adds value showing to the contents of the memory You should be able to clear the memory with MC or some similar button.
