bit—one binary digit, either 0 or 1
byte—eight related bits of data, an eight-bit binary number. Also used to
denote the amount of memory required to store one byte of data.
the range of frequencies present in a signal, or the range of frequencies to
which a measuring device can respond
a memory address that serves as the starting address for programmable
registers. All other addresses are located by adding to the base address.
serial communications data transmission rate expressed in bits per second
(b/s)
binary-coded decimal
a number system with a base of 2
basic input/output system or built-in operating system
a signal range that includes both positive and negative values (for example,
–5 V to +5 V)
PPI B interrupt request bit for Port A
PPI B interrupt request bit for Port B
a type of coaxial signal connector
bidirectional data lines for Port A of PPI B
bidirectional data lines for Port B of PPI B
bidirectional data lines for Port C of PPI B
a type of switching contact that is completely disengaged from one terminal
before it connects with another terminal
the voltage high enough to cause breakdown of optical isolation,
semiconductors, or dielectric materials. See also working voltage.
