sequenced packet protocol
Abbreviated as SPP, a networking protocol that provides reliable transport of packets with flow control in environments where multiple transport connections are established. SPP uses destination ID reference numbers to identify the target end of a transport connection; sequence numbers to keep transmitted packets in the order in which they were sent; and acknowledge numbers that are assigned to the last packet in a sequence that a destination received properly to indicate that the transmission is complete and successful.

- sequential access
)Refers to reading or writing data records in sequential order, that is, one record after the other. To read record 10, for example, you would first need to read records 1 through 9. This differs from random access, in which you can read and write records in any order. Some programming languages and operating systems […]
- serial
One by one. Serial data transfer refers to transmitting data one bit at a time. The opposite of serial is parallel, in which several bits are transmitted concurrently.
- serial mouse
A mouse that connects to a computer via a serial port. The other common type of mouse is a PS/2 mouse, which plugs into a PS/2 mouse port.
- SPI
(1) Short for Serial Peripheral Interface, a full-duplex synchronous serial interface for connecting low-/medium-bandwidth external devices using four wires. SPI devices communicate using a master/slave relationship over two data lines and two control lines: Master Out Slave In (MOSI): supplies the output data from the master to the inputs of the slaves. Master In Slave […]
- Serial Port
A port, or interface, that can be used for serial communication, in which only 1 bit is transmitted at a time. Most serial ports on personal computers conform to the RS-232C or RS-422 standards. A serial port is a general-purpose interface that can be used for almost any type of device, including modems, mice, and […]
