Encryption in computer networks involves encoding data into an unreadable format using algorithms and keys. Only those with the corresponding decryption key can decode and access the original information. This ensures data confidentiality and security during transmission over the network, protecting sensitive information from unauthorized access or interception by hackers or malicious actors.

Cloud computing involves delivering computing services, including servers, storage, databases, networking, software, and analytics, over the internet. Users access these services on-demand from cloud providers’ servers, paying only for what they use. Its advantages include cost-effectiveness, scalability, flexibility, and the ability to access resources from anywhere with an internet connection. Additionally, it reduces the need for physical infrastructure maintenance and allows for rapid deployment of applications and services.
