The advantages of distributed operating systems are distribution and what

1. Scalability: Distributed computer systems have good scalability, which can be increased according to demand or Reduce the calculation nodes.When it is necessary to handle larger-scale tasks or increase the capacity of the system, the system can be expanded by adding computing nodes. This enables the system to adapt to the changing computing needs.

2. Autonomy. Each node in the distributed system contains its own processor and memory, each with the function of processing data independently. Usually, they are equal in status and have no master or secondary. They can not only carry out work autonomously, but also use shared communication lines to transmit information and coordinate task processing. 3. Con parallelism.

3. The advantage of distributed systems is networking, which provides the possibility for the expansion of the system. However, the biggest problem of distribution is also various uncertainties brought about by networking. From an industrial perspective, network problems are the original sin of distributed systems, which brings to the design and implementation of distributed systems. Great difficulties and challenges.

4. Improve performance: The distributed operating system can assign computing tasks to multiple nodes for execution, thus improving the processing power of the system. Especially in the field of large-scale data processing and high-performance computing, the advantages of distributed operating systems are more obvious.

5. A distributed program consists of several program modules that can be executed independently, which are distributed on multiple computers in a distributed processing system and executed simultaneously. Compared with centralized programming languages, it has three characteristics: distribution, communication and robustness.

harmonyos system introduction

harmonyos system introduction: At present, this system can be used in mobile phones, tablets, watches, smart homes and other devices.It is similar to the well-known ios, Android and other operating systems, and is mainly used on mobile devices. It adheres to Huawei's concept of Internet of Everything and can support the linkage of devices using the system.

HarmonyOS 2, regardless of the size of the device, only needs one system to cover large and small intelligent terminal devices such as memory as 128K and more than 4GB.

HarmonyOS is a brand-new distributed operating system for the era of the Internet of Everything.

harmonyos, that is, Hongmeng OS, is a future-oriented distributed operating system launched by Huawei for all scenarios (mobile office, sports health, social communication, media, entertainment, etc.). It was officially released in August 2019.

What is a distributed operating system?

1. Distributed Software Systems is a software system that supports distributed processing and performs tasks on a multiprocessor architecture interconnected by a communication network.

2. Distributed System is a system in which multiple computers and communication software components realize specific functional services through computer networks. Because it is a system built on the network, the distributed system has a high degree of cohesion and transparency. Clear nature.

3. Distributed operating system: a software system built on the network. Network operating system: It is a software program that can replace the operating system and is a special operating system that provides services to network computers.Different characteristics Distributed operating system: with a high degree of cohesion and transparency.

4. A distributed system is a software system built on the network. Process the assistance task, and then integrate the results. In a distributed system, a group of independent computers present a unified whole to the user, just like a system.

5. Distributed Operating System is responsible for managing distributed processing system resources and controlling the operation of distributed programs. The difference between it and the centralized operating system lies in resource management, process communication and system structure. It is a special multi-processor computer system.
