Defining Networked Systems
Networked systems allow multiple computers to communicate, sharing resources and information. They can be local or distributed, underpinning the internet, supporting collaborative work across the globe.
OS Role in Networking
An Operating System (OS) manages hardware and provides services for applications. In networked systems, the OS handles networking tasks like TCP/IP processing, ensuring efficient and secure data transmission.
Evolution of Network OS
Early networked systems used basic OS with add-ons for networking. Modern Network Operating Systems (NOS) are integral, offering sophisticated functions like automated backups, advanced security, and resource sharing across networks.
Importance of Synchronization
In distributed systems, time synchronization is crucial. Protocols like NTP ensure that all system clocks across a network are synchronized, which is vital for transaction ordering, logging, and consistency.
Resource Sharing Complexity
Resource sharing in networked systems introduces complexity. Issues like concurrent access, resource allocation, and load balancing require advanced OS mechanisms to manage effectively.
Security in Networked OS
Networked OS security is multifaceted, including measures such as encryption, authentication, and access control. Intrusion detection systems and firewalls are integrated to protect against unauthorized access and attacks.
Future of Networked Systems
Future networked systems predict growth in edge computing, where processing happens near data sources. This reduces latency, allowing real-time processing and analytics, paving the way for advancements in IoT and AI.
