buszarchitektúrává

Buszarchitektúra refers to a computer architecture where multiple components are connected via a shared bus. This bus acts as a communication pathway, allowing different hardware components, such as the CPU, memory, and input/output devices, to exchange data. In this model, a bus consists of several lines, typically including address lines, data lines, and control lines. The address lines specify the location of data, the data lines carry the actual information, and the control lines manage the timing and flow of data transfer.

The primary advantage of bus architecture is its simplicity and cost-effectiveness. It allows for easy expansion by adding new devices that can be connected to the bus. However, a significant drawback is the potential for bus contention, where multiple devices try to access the bus simultaneously, leading to performance bottlenecks. The speed of the bus also becomes a limiting factor for the overall system performance, as all data transfers must go through this shared medium. Early personal computers heavily relied on bus architectures like the ISA (Industry Standard Architecture) and later PCI (Peripheral Component Interconnect). While modern systems have evolved to more complex interconnects like PCIe, the fundamental concept of a shared pathway for communication between components originated with bus architectures. Understanding bus architecture is crucial for grasping the evolution of computer hardware design and the principles of data transfer within a system.
