● The data （74） includes the function of updating data on a database, and retrieving ata from a database.（74）

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.

In large computing systems, the term "main storage" is(71) to "memory". "Buffer" mainly indicates a special-purpose storage or storage area allowing, through(72) storage, the data transfer between two functional units having different transfer characteristics. A buffer storage is used between non-synchronized devices or where one is(73) and the other is parallel or between those having different trans far rates. "(74) (memory)" is also a special-purpose buffer storage, smaller and faster than main storage, used to hold a copy of instructions and data obtained from main storage and likely to be needed next by the processor. "Register" is commonly composed of a part of internal storage having a specified storage(75) and usually intended for a specific purpose.; ______ is permanently stored in the computer and provides a link between the hardware and other programs that run on the PC.; is permanently stored in the computer and provides a link between the hardware and other programs that run on the PC.; ● （73） is a method used in Critical Path Methodology for constructing a project schedule network diagram that uses boxes or rectangles, referred to as nodes, to represent activities and connects them with arrows that show the logical relationships that exist betweenthem.（73）; ● (73) are essential for the protection of data.（73）; You are the administrator of several SQL Server 2000 computers.

The .udl files are frequently updated as connection details change.; ●The Programming languages are designed to (73) the communication between human and computers.; ●The Programming languages are designed to (73) the communication between human and computers.; Operating systems provide （） between users and the computer.; In the open systems interconnection (OSI) reference model, "layer" means one of seven conceptually complete,(71) arranged groups of services, functions, and protocols, that extend across all open systems.Application layer provides means for the application(72) to access the OSI environment. Presentation layer provides for the selection of a common syntax for representing data.(73) layer provides the means necessary for cooperating presentation entities to organize and synchronize their dialog and to manage their data exchange. Transport layer provides a reliable end-to-end data transfer service. Network layer provides for the entities in the transport layer the means for transferring blocks of data, by(74) and switching through the network between the open systems in which those entities reside. Data link layer provides services to transfer data between network layer entities. Physical layer provides the mechanical, electrical, functional, and procedural means to establish, maintain and(75) physical connections for transfer of bits over a transmission medium.; In data communication, data link is those parts of two data terminal equipments that are controlled by a protocol along with the(71) data circuit, which together enable data(72). So-called protocol means, in short, a set of rules that determines the behavior. of functional units in achieving communication.Data circuit, however, consists of a pair of(73) transmission channels that provides a means of two-way data transmission. Between data switching exchanges, the data circuit may or may not include data circuit-terminating equipment (DCE), depending on the type of(74) used at the data switching exchange. Between a data station and a data switching exchange or data concentrator, the data circuit includes the DCE at the data station end, and may include equipment(75) to a DCE at the data switching exchange or dam concentrator location.; The data ______ includes the function of updating data on a database, and retrieving data from a database.; Business intelligence （BI） is the integrated application of data warehouse, data mining and （73）．; Feedback refers to any information which provides a report on the result of communication which takes place not only between the listener and the speaker.（）; The difference between a class A and a class B EPIRB is that the class A EPIRB（）.; ●A (73) is a named memory block.
