Which of the following is a technique that marks the beginning of computer communications?

Correct option is C

Time-sharing is a technique that enables multiple users to access a computer system simultaneously by sharing processor time. This method allowed multiple tasks to be executed concurrently, marking a significant advancement in computer communications. It laid the foundation for modern networking and interactive computing.
Important Key Points:
1. Definition of Time Sharing: Time-sharing is a computing technique where multiple users can interact with a system at the same time by allocating CPU time among different tasks.
2. Beginning of Computer Communications: This method enabled direct interaction between users and the system, leading to the evolution of computer networks and modern remote computing.
3. Advancement Over Batch Processing: Unlike batch processing, where jobs were executed sequentially, time-sharing allowed simultaneous execution of tasks, making computers more efficient and responsive.
4. Key Contributions: It was a major breakthrough in computing, leading to the development of modern operating systems, multi-user environments, and the Internet.
Knowledge Booster:
· User Environment refers to the interface and settings available for user interaction but does not mark the beginning of computer communication.
· Batch Environment involves executing multiple jobs in batches without real-time user interaction, which does not signify the start of computer communication.
