The data station usually means a(71)unit that provides data for transmission, that accepts transmitted data, and that performs all functions necessary for communication with another functional unit. Data stations may be divided into two kinds, the primary stations and the secondary stations, (72)control functions.In(73)data link control, the primary station is the data station that supports the primary control functions of the data link, generates commands to be transmitted, and interprets received responses. Specific responsibilities assigned to the primary station include initialization of control signal interchange, organization of data flow and actions regarding error control and error recovery functions. The secondary station executes data link control functions as (74)by the primary station, interprets received commands and (75) responses to be transmitted.

A．performance

B．functional

C．capacity

D．quality

根据以下资料，回答下列各题。The use of containers, which started more than 40 years ago, in

intercontinental traffic is now available in most sea cargo transport worldwide. The unit (41) is used to express the relative number of containers based on the equivalent length of a 20’ container. The (42) container service broadly means that the whole container received by the carrier is packed at the shipper’s or the forwarder’s premises, and the delivery of that same whole container to the consignees. The (43) container service broadly means that the whole container received by the carrier is packed at the shipper’s or the forwarder’s premises, and that same whole container is emptied at the carrier’s container freight station at the port of destination. The (44) broadly means that the delivery of the loose cargo to the carrier’s freight station at the port of origin is packed into the whole container, and the delivery of that same whole container to the consignees. The (45) container service broadly means that the delivery of the loose cargo to the carrier’s container freight station at the port of origin is packed into the whole container, and that same whole container is emptied at the carrier’s freight station at the port destination.
