Cyber-security. Measures used to protect computer systems from cyber-attack. May include virus protection, malware protection, and use of passwords.

Denial-of-service (DOS) attack. A form of cyber-attack that aims to shut down a network or service, and make it unavailable to users. A distributed denial-of-service is similar, and aims to flood a network or service with traffic, so that it is unable to function.

Streaming. The digital distribution of content via the internet. It is mostly used in the context of television, but podcasts are also delivered via streaming. In technical terms, streaming is the delivery of data to a computer as a continuous stream (rather than a single download).
