The CPU is the heart of the computer. A program is a sequence of instructions stored in main memory . When a program is run, the CPU fetches the instructions and executes or follows the instructions.
Where are program instructions and data stored?
Memory is the part of the computer that holds data and instructions for processing. Although closely associated with the central processing unit, memory is separate from it. Memory stores program instructions or data for only as long as the program they pertain to is in operation.
Where instructions are stored?
An instruction, stored in the memory , is fetched into the control unit by supplying the memory with the address of the instruction. The control unit decodes the instruction in order to find the sequence of operation necessary to execute it.
Are program instructions stored on the stack?
Stack is hardware supported solutions, while heap is a standard library supported solution. So, your code will be located in the code segment, your static data and heap will be located in the data segment, and the stack will be located in the stack segment .
Where are the instructions stored in the processor?
Data that the CPU is processing is stored in the memory . Instructions (programs) for the CPU are also stored in the memory just like data. One of the most important feature of a stored program computer is being able to store the programs as well as the data together in the memory.
When a program is running its instructions are stored on a computer’s RAM because it?
| When a program runs on a computer, it is stored in main memory | When a program runs on a computer, the part of the computer that carries out the instructions is called the CPU | When a program is not running, it is stored on a disk | Monitors, printers, status lights are all examples of _____ devices. output |

How a program is loaded into memory and then executed?
A program loaded into memory and executing is called a process . In simple, a process is a program in execution.
What are 5 types of instruction operations?
- Data handling and memory operations.
- Arithmetic and logic operations.
- Control flow operations.
- Coprocessor instructions.
- Number of operands.
Is main memory RAM or ROM?
Memory Basics
Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory . It is also called as read write memory or the main memory or the primary memory. The programs and data that the CPU requires during execution of a program are stored in this memory.
What is stored program concept?
Stored-program computer, a computer that stores instructions in its memory to enable it to perform a variety of tasks in sequence or intermittently . ... Presper Eckert, contributed to this idea, which enabled digital computers to become much more flexible and powerful.
Where is stack pointer stored?
Simpler processors store the stack pointer in a regular hardware register and use the arithmetic logic unit (ALU) to manipulate its value. Typically push and pop are translated into multiple micro-ops, to separately add/subtract the stack pointer, and perform the load/store in memory.
Is used to receive instructions from database?
SQL commands are instructions. It is used to communicate with the database. It is also used to perform specific tasks, functions, and queries of data. SQL can perform various tasks like create a table, add data to tables, drop the table, modify the table, set permission for users.
How is stack data stored?
A stack is a special area of computer’s memory which stores temporary variables created by a function . In stack, variables are declared, stored and initialized during runtime. It is a temporary storage memory. When the computing task is complete, the memory of the variable will be automatically erased.
What format does data store?
The BCD format is usually used to store data.
Which computer memory is known as the backup memory?
Secondary memory is known as a Backup memory or Additional memory or Auxiliary memory. Data is directly accessed by the processing unit. Data cannot be accessed directly by the processor. It is first copied from secondary memory to primary memory.
What type of device is CPU?
The CPU (Central Processing Unit) is the part of a computer system that is commonly referred to as the “brains” of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program .
