Study Notes
Advancements in Technology
- Over the past two decades, there have been significant advancements in microelectronic technology, resulting in fast and inexpensive processors.
- Similarly, communication technology has improved, leading to cost-effective and highly efficient computer networks.
Distributed Computing System
- The combination of these advancements has changed the price-performance ratio, favoring the use of interconnected, multiple processors over a single, high-speed processor.
- A distributed computing system is a collection of processors connected by a communication network, where each processor has its own local memory and peripherals.
- Communication between processors takes place by message passing over the communication network.
- Processors and their resources are referred to as a node, site, or machine of the distributed computing system.
Types of Computer Architectures
- Tightly coupled systems: processors share a single system-wide primary memory (address space), and communication occurs through the shared memory.
- Loosely coupled systems: processors do not share memory, and each has its own local memory; communication occurs through message passing over the network.
Characteristics of Distributed Computing Systems
- Processors can be located far from each other, covering a wider geographical area.
- The number of processors can be expanded almost unlimitedly, unlike tightly coupled systems.
- Each processor has its own local resources, while others are remote.
