method of representing negative numbers in binary, whereby the negative representation is derived by inverting each bit from right to left, but only after detecting the first bit that is a 1
two's complement

In binary representation of both positive and negative numbers, this term refers to the mostsignificant bit
sign bit

a seven bit binary code used to represent a standard character set to allow communication and data transfer between digital devices
ASCII

method of representing negative numbers in binary, whereby the negative representation of a number is derived simply by inverting each bit  that is changing each one to a zero and each zero to a one
one's complement

The leftmost position of a binary number
mostsignificant bit

Name given to the fixed numeric value given to each position of a number so that a number of any size can be expressed by whatever the number system
place value

term given to the right half of a 16bit word
leastsignificant byte

A fourbit code, by which each decimal digit from 0 through 9 is represented by its binary equivalent. This coee provides a method that allows decimal numbers to be input to or output from a digital system
binary coded decimal

this number format which allows representation of a very large and very small numbers, consists of two parts  the mantissa and the exponent
floatingpoint numbers

A binary code, similar to BCD, in which only one bit changes and the number is incremented. This code is used in positioning decoders where positioning accuracy is required
gray code

This term refers to a grouping of eight binary digits
byte

The term given t the lefthalf of a sixteen bit word
mostsignificant byte

A grouping of sixteen binary digits, or two or more butes
word

name of the number system based on the number two
binary

the name given t each position or digit of a binary number
place value

an ordered scheme whereby a fixed set of symbols is used to represent numeric values

In cutoff, the BJT base current is
zero

In cutoff, the BJT collector current (Ic) is

One way to design for a power transistor is allow ___ more base current than you actually need, to make sure the device remains saturated.
5x

In both cutoff and saturation, _____ power is dissipated in the transistor.
minimum

In saturation, the BJT base current is
maximum

If the transistor is biased into saturation or cutoff, it will be used as
a switch

A bipolar junction transistor (BJT) can be used in many circuit configurations; as an amplifier, oscillator, filter rectifier or just used as a
switch

For use as a switch, the BJT operates in the regions of the output curves called
saturation and cutoff
