The Von Neumann architecture is a computer design model that uses a single storage structure to hold both instructions and data. This architecture was first introduced by ​ ​

Select answer

​ (Hint: He was a Hungarian-American mathematician and physicist) in the year ​

Select answer

(Hint: It's in the mid-1940s).

In a Von Neumann machine, the main components include the Central Processing Unit (CPU), memory, and input/output devices. The CPU itself is divided into two main parts: the ​

Select answer

(Hint: Think "brain" of the CPU, responsible for executing instructions) and the ​

Select answer

(Hint: This part handles arithmetic and logical operations).

The memory in a Von Neumann architecture is often divided into two types: ​

Select answer

(Hint: Volatile memory used for temporary storage while the computer is running) and ​

Select answer

(Hint: Non-volatile memory used for long-term storage).

The process of executing an instruction in a Von Neumann machine follows a specific cycle known as the fetch-decode-execute cycle. During the fetch phase, the CPU retrieves an instruction from ​

Select answer

(Hint: This is the fast storage area close to the CPU). In the decode phase, the CPU interprets the instruction. Finally, in the execute phase, the CPU performs the operation dictated by the instruction.
