If the control unit controls other units of the CPU, which unit stores instructions,data and intermediate results.
Answer Details
The unit that stores instructions, data, and intermediate results in a CPU is the Memory unit.
The Memory unit plays a crucial role in a computer system as it is responsible for storing and retrieving data and instructions that are needed for the CPU to execute tasks. It provides a place for the CPU to read data from and write data to.
When a program is executed, the instructions and data required by the CPU are loaded into the Memory unit. This allows the CPU to easily access and manipulate the information needed to perform calculations or carry out operations.
The Memory unit can be thought of as a large storage area or workspace where the CPU can temporarily store and retrieve information as needed. It consists of different types of memory, such as the cache, random access memory (RAM), and read-only memory (ROM).
The control unit of the CPU is responsible for coordinating and controlling the activities of other units, including the Memory unit. It fetches instructions from the Memory unit and directs the necessary data to be accessed or stored in the Memory unit. However, it is important to note that the Control unit itself does not store instructions, data, or intermediate results. It mainly focuses on facilitating the execution of instructions and coordinating the flow of data between different units.
The Arithmetic section of the CPU performs arithmetic calculations such as addition, subtraction, multiplication, and division. However, it does not directly store instructions, data, or intermediate results. Its role is primarily to carry out mathematical operations on data provided by the Memory unit.
The Logic section of the CPU handles logical operations like comparisons and logical decisions. Similar to the Arithmetic section, it does not store instructions, data, or intermediate results on its own, but rather operates on data accessed from the Memory unit.
In summary, while the Control unit controls other units of the CPU, it is the Memory unit that stores instructions, data, and intermediate results. The Memory unit serves as a central storage space for the CPU, allowing it to efficiently access and manipulate the information necessary for processing tasks.
