According to Communicaid.com, the concepts of high context and low context refer to how people communicate in different cultures. Differences can be derived from the extent to which meaning is transmitted through actual words used or implied by the context.

High context implies that a lot of unspoken information is implicitly transferred during communication. People in a high context culture such as Saudi Arabia tend to place a larger importance on long-term relationships and loyalty and have fewer rules and structure implemented.
Low context implies that a lot of information is exchanged explicitly through the message itself and rarely is anything implicit or hidden. People in low context cultures such as the UK tend to have short-term relationships, follow rules and standards closely and are generally very task-oriented.
