Introduction Distributed computing systems refer to a network of interconnected devices that share resources and work together to achieve a common goal. evolution of distributed computing systems has been rapid, and it has transformed way we use technology in our daily lives. From simple file sharing systems to advanced cloud computing, distributed computing systems have come a long way. In this article, we will discuss evolution of distributed computing systems and explore some of examples. Early Days of Distributed Computing The early days of distributed computing can be traced back to 1960s, where researchers began experimenting with idea of sharing ... Read More
Introduction Distributed systems have become an integral part of our modern-day technological infrastructure. They have made it possible to deliver services at scale, provide better resilience, and enable better fault tolerance. However, designing distributed systems is a challenging task, and one of most significant challenges is maintaining ordering of events in system. This article will discuss event ordering in distributed systems and provide examples of different techniques used to achieve it. Event Ordering Event ordering is essential in distributed systems because it determines order in which events occur. In a distributed system, events can happen concurrently on different nodes, and ... Read More
Introduction Ethernet is most popular local area network (LAN) technology, which enables transfer of data packets between different devices such as computers, routers, and switches. Ethernet uses a variety of protocols to transmit data packets over a network. One of crucial protocols is Ethernet transmitter algorithm, which governs way data is transmitted over Ethernet network. In this article, we will discuss Ethernet transmitter algorithm, its subheadings, and examples. Overview of Ethernet Transmitter Algorithm The Ethernet transmitter algorithm is a set of rules that governs transmission of data packets over an Ethernet network. algorithm ensures that data packets are transmitted in ...
