843 Data processing services
8431 84310 Input preparation services
Data recording services such as key punching, optical scanning or other methods for data entry.
8432 84320 Data-processing and tabulation services
Services such as data processing and tabulation services, computer calculating services, and rental services of computer time.
8433 84330 Time-sharing services
This seems to be the same type of services as 84320. Computer time is bought; if it is bought from the customer's premises, telecommunications services are also bought. Data processing or tabulation services may also be bought from a service bureau. In both cases the services might be time sharing processed. Thus, there is no clear distinction between 84320 and 84330. |
