Keywords

💡Network

A network, in the context of the video, refers to a group of computers or devices connected together for communication and data sharing. It is integral to the theme of the video, which discusses protocols and processes that facilitate communication within and between networks. For example, the script mentions 'नेटवर्क' (network) in relation to protocols and data exchange processes.

💡Protocol

A protocol is a set of rules governing the format and transmission of data. It is a key concept in the video, as it explains how data is exchanged securely and efficiently across networks. The script uses the term in the context of a 'कृष्ण प्रोटोकॉल' (lightweight protocol), which suggests a focus on efficiency.

💡Authentication

Authentication is the process of verifying the identity of a user or device. It is crucial for secure access to network resources, as mentioned in the script where it discusses how a user ID and password are used to gain access to a server.

💡Encryption

Encryption is the process of converting data into a code to prevent unauthorized access. It is a fundamental concept in the video, which discusses how data is secured during transmission. The script refers to 'एनक्रिप्टेड' (encrypted) tickets, indicating the use of encryption to protect data.

💡Ticket

In the script, a ticket seems to represent a token or a set of data that grants access or permission for certain operations within a network. It is related to the theme of access control and is mentioned in the context of 'टिकट' (ticket) generation and usage.

💡Timestamp

A timestamp is a record of when a particular event occurred. In the video, it is used to track and manage the lifecycle of a ticket, ensuring that it is valid only for a specified duration, as indicated by phrases like 'टाइमस्टैंप के साथ जनरेट हो चुकी है' (generated with a timestamp).

💡Database

A database is a structured set of data held in a computer, allowing for storage and retrieval. The script mentions a 'डाटाबेस' (database) in the context of storing and managing data related to network operations and user activities.

💡Integration

Integration in this context refers to the process of combining different systems or applications to work together. The script discusses 'इंटिग्रेशन' (integration) in relation to how different components of the network interact and exchange data.

💡Access Control

Access control is the process of restricting access to resources based on the identity of the user or system. The video's theme involves managing access to network resources, as shown by the use of user IDs, passwords, and tickets to control entry.

💡Decentralization

Decentralization refers to the distribution of authority or functions away from a central location. The script mentions 'डिस्ट्रीब्यूशन सेंट्रल' (decentralization) in the context of a database, suggesting a system that is not reliant on a single central point of control.

💡Cryptography

Cryptography is the practice of secure communication techniques that prevent third parties from accessing private data. The script touches on 'सीमेंट की क्रिप्टोग्राफी' (cement cryptography), which seems to be a metaphor for a strong encryption method used to secure data.
