Explain the concept of phrasal verbs with technological meanings and give examples.

Phrasal verbs are a type of multi-word verb that consists of a main verb combined with one or more particles (prepositions or adverbs). These particles can significantly alter the meaning of the main verb, creating a new idiomatic expression. In the context of technology, phrasal verbs with technological meanings are commonly used to describe actions or processes related to technology and digital devices.

Here are some examples of phrasal verbs with technological meanings:
