Q & A

What is a distributed system, and how does it work?

A distributed system is a collection of physically separate computers that are interconnected via a network. These systems work together to perform tasks efficiently by sharing the computational load. For example, when using Google Search, multiple computers collaborate to process data and display search results quickly.

How does a network operating system (NOS) function in a computing environment?

A Network Operating System (NOS) is responsible for managing and optimizing computer networks. It regulates data traffic, assigns IP addresses, and ensures smooth communication between devices. It acts like traffic police to ensure the network operates efficiently and autonomously.

What are the main features of a client-server system?

A client-server system involves a client requesting data or services from a server. The server, which stores the data, responds to the client's requests. This model offers advantages such as better data management, enhanced security, and high scalability. Examples include web servers and cloud services like Google Drive.

What distinguishes a peer-to-peer (P2P) system from a client-server system?

In a Peer-to-Peer (P2P) system, all devices act as both clients and servers without a central server. This decentralized approach contrasts with client-server systems, where the server is responsible for providing resources or data to clients. Examples of P2P systems include torrenting and blockchain technology.

What is the role of real-time embedded systems?

Real-time embedded systems are integrated into devices that require immediate responses to inputs. These systems continuously monitor and control functions in real-time, such as medical devices monitoring vital signs and providing instant alerts in case of abnormalities, like an irregular heartbeat.

Why are distributed systems considered scalable?

Distributed systems are scalable because they can divide computational tasks across multiple computers, allowing them to handle increasing loads more efficiently. The system can easily expand by adding more computers to the network without significantly affecting performance.

How does a network operating system improve the overall efficiency of a network?

A Network Operating System (NOS) enhances network efficiency by optimizing data transfer, managing network resources, and ensuring smooth communication between devices. It also plays a crucial role in minimizing data congestion and managing IP addresses, ensuring that the network operates without interruption.

What are the security benefits of a client-server system?

Client-server systems offer better security because the server, where data is stored, can be properly secured and monitored. Unlike decentralized systems, data management is centralized, allowing for better control over who accesses the data and ensuring that security protocols are enforced.

What is an example of a decentralized system, and how does it work?

An example of a decentralized system is a Peer-to-Peer (P2P) network, where devices share data directly without relying on a central server. Each device can act as both a client and a server, and data is distributed across the network, making it more resilient and efficient in handling large amounts of data.

How do real-time embedded systems impact critical fields like healthcare?

Real-time embedded systems are crucial in fields like healthcare because they provide immediate responses to changes in monitored parameters, such as heart rate or blood pressure. In medical devices, these systems ensure that any abnormal readings are detected instantly, triggering immediate actions, such as alarms or adjustments, to prevent potential health risks.
