Summary of Computer Networks - Basic Characteristics
The video discusses the basic characteristics of computer networks: fault tolerance, scalability, quality of service, and security.
- fault tolerance is the ability of a network to continue working despite failures, ensuring no loss of service.
- scalability is the ability of a network to grow based on needs and maintain good performance.
- quality of service involves setting priorities and managing data traffic to reduce data loss and delays.
- security is the ability to prevent unauthorized access, misuse, or forgery, and provide confidentiality, integrity, and availability.
Examples
- Examples are provided for each characteristic, such as fault tolerance in rerouting data, scalability in the internet, and quality of service prioritizing real-time communication.
Importance of security
The importance of security is highlighted through the prevention of unauthorized access and ensuring data confidentiality, integrity, and availability.
