Concept
The Von Neumann Bottleneck refers to the limitation on throughput in a computer system caused by the separation of the CPU and memory, as they can only communicate over a shared bus system, restricting data transfer rates. This architectural limitation creates a performance bottleneck because the speed of the CPU outpaces the speed at which data can be delivered from memory, causing inefficiencies in processing tasks.

Concept
Von Neumann Architecture is a computer architecture model that describes a system where the data and program are stored in the same memory space. This design forms the basis for most modern computers, allowing for sequential execution of instructions and enabling the stored-program concept.
Concept
The CPU-memory bus is a communication pathway used in computer architecture to connect the central processing unit (CPU) and main memory, facilitating data transfer between the two components. Its efficiency and speed are critical for overall system performance, impacting how quickly a computer can execute instructions and process information.
Concept
Data throughput refers to the rate at which data is successfully transferred from one location to another, measured in bits per second (bps). It's a critical measure of network performance and efficiency, impacting everything from internet speed to the performance of data-driven applications.
Concept
A performance bottleneck occurs when a particular component of a system limits overall performance, causing delays or reduced efficiency. Identifying and addressing bottlenecks is crucial for optimizing system performance and ensuring smooth operation.
Concept
Processor speed, often measured in gigahertz (GHz), dictates the number of cycles a CPU can execute per second, directly impacting the performance and efficiency of a computer. However, real-world performance also depends on factors like core count, architecture, and thermal management, making raw speed just one of many important considerations in CPU performance.
Concept
Memory bandwidth refers to the rate at which data can be read from or written to a memory by a processor, directly impacting the performance of computational tasks. It is a critical factor in determining the efficiency of data-intensive applications, especially in high-performance computing and graphics processing.
Concept
Computer architecture refers to the design and organization of a computer's fundamental operational structure, encompassing the hardware components and their interactions. It is crucial for optimizing performance, efficiency, and scalability, impacting how software and hardware work together to execute tasks effectively.
Concept
Harvard Architecture is a computer architecture that uses separate storage and signal pathways for instructions and data, allowing simultaneous access to both and improving processing speed. This architecture contrasts with the Von Neumann Architecture, where instructions and data share the same bus, often leading to bottlenecks.
