1 data-link layer
"Layer two of the OSI model. A layer that packages raw bits from the physical layer into frames (logical, structured packets for data). This layer is responsible for transferring frames from one computer to another, without errors. After sending a frame, the data-link layer waits for an acknowledgment from the receiving computer." -
2 data collection
The process of gathering information by sending and receiving HTML forms or InfoPath forms from Access. -
3 CRC
"A procedure used in checking for errors in data transmission. CRC error checking uses a complex calculation to generate a number based on the data transmitted. The sending device performs the calculation before transmission and includes it in the packet that it sends to the receiving device. The receiving device repeats the same calculation after transmission. If both devices obtain the same result, it is assumed that the transmission was error free. The procedure is known as a redundancy check because each transmission includes not only data but extra (redundant) error-checking values. Communications protocols such as XMODEM and Kermit use cyclical redundancy checking." -
4 cyclic redundancy check
"A procedure used in checking for errors in data transmission. CRC error checking uses a complex calculation to generate a number based on the data transmitted. The sending device performs the calculation before transmission and includes it in the packet that it sends to the receiving device.

The procedure is known as a redundancy check because each transmission includes not only data but extra (redundant) error-checking values.

6 buffer
An area of memory reserved for temporarily holding data before that data is used by a receiving device or application. Buffering protects against the interruption of data flow. -
7 MIME
A common method for transmitting non-text data through Internet e-mail. MIME encodes non-text data as ASCII text and then decodes it back to its original format at the receiving end. A MIME header is added to the file which includes the type of data contained and the encoding method used. -
8 Multipurpose Internet Mail Extensions
A common method for transmitting non-text data through Internet e-mail. MIME encodes non-text data as ASCII text and then decodes it back to its original format at the receiving end. A MIME header is added to the file which includes the type of data contained and the encoding method used.English-Arabic terms dictionary > Multipurpose Internet Mail Extensions

9 modem compression
A technique used to reduce the number of characters transmitted without losing data content. The transmitting modem compresses the data and the receiving computer or modem decompresses the data back to its original state. -
10 asynchronous communication
"A form of data transmission in which information is sent and received at irregular intervals, one character at a time. Because data is received at irregular intervals, the receiving modem must be signaled to let it know when the data bits of a character begin and end. This is done by means of start and stop bits."English-Arabic terms dictionary > asynchronous communication

11 import
To bring information from one system or program into another. The system or program receiving the data must somehow support the internal format or structure of the data.
