Study Notes

Central Processing Unit (CPU)

CPU is the primary component responsible for executing instructions, often referred to as the computer's "brain."
In multiprocessor systems, multiple CPUs or cores collaborate to enhance performance and efficiently execute tasks.
Distributing tasks among CPU cores enhances gaming experiences by ensuring smooth and seamless operation.

Memory (RAM)

RAM (Random Access Memory) is used for temporarily storing data that is actively being processed by the computer.
Adequate RAM is essential in multiprocessor systems, allowing all processors quick access to necessary data.
Sufficient RAM enables users to switch between tasks fluidly, minimizing lag and maintaining productivity.

Cache Memory

Cache memory is a smaller, faster memory type located closer to CPU cores, designed to expedite data access.
It stores frequently accessed data, reducing the need for the CPU to retrieve it from the slower main memory.
Utilizing cache memory enhances overall processing speed and makes user interactions quicker and more efficient.

Input/Output (I/O) Devices

I/O devices facilitate interaction between the computer and external elements such as keyboards, mice, displays, and storage systems.
Multiprocessor systems efficiently manage I/O devices to ensure uninterrupted data flow during simultaneous tasks.
The system can concurrently process multiple I/O tasks, allowing activities like movie playback and file transfers without disruption.

Bus System

The bus system acts as the communication network among all components within a computer, enabling data exchange.
A fast and efficient bus system is crucial in multiprocessor setups to accommodate higher data traffic.
Similar to how a network router manages data for seamless streaming, the bus system ensures efficient data flow between processors, memory, and I/O devices.

Operating System

The operating system (OS) governs the computer’s hardware and software resources.
In multiprocessor systems, the OS plays a critical role in distributing tasks efficiently across all available processors.
The OS functions like a project manager, optimizing task allocations to enhance overall system effectiveness and efficiency.
