accessor method - a method that accesses an object but does not change it
actual parameter - the expression supplied for a formal parameter of a method by
the caller
address - a location in memory at which a binary number (usually a byte, or value
of 8 bits) is stored. The location in memory can itself be identified by a binary
number - this number, the absolute or explicit address, gives the absolute location
of the address in memory, while a relative address specifies a location memory
(some other address only in relation to the current, or base, address. All access to
memory is access to to a cell of memory found at a specified address.
algorithm - a well-ordered collection of unambiguous and effectively computable
operations that, when executed, produces a result and halts in a finite amount of
time
[[an unambiguous, executable, and terminating specification of a way to solve a
problem
argument - an actual parameter in a method call, or one of the values combined
by an operator]]

ASCII - The American Standard Code for Information Exchange - a character-
encoding scheme based on the English alphabet used to represent text in
computers. It uses 8 bits to represent each character, so it is able to encode a total
of 2^8 = 256 different characters. These are assigned the integer values 0 to 255.
Only 32 to 126 have been assigned to printable characters. The ASCII has been
largely supplanted by UNICODE and the UCS (universal character set), which are
backwards compatible with it (commonly encoded using UTF-8, UTF-16, and UTF-
32 representing character sets using 8, 16, and 32 bits respectively. UTF-16 can
represent 65,536 characters.)
binary - the binary, or the base-2, positional numbering system represents
numerical values using only two symbols, 0 and 1
bit - a contraction of binary digit; the smallest unit of information, having two
possible values: 0 and 1. A data element consisting of n bits has 2ⁿ possible
boolean - a data type with two possible value representing true and false.
boolean expression - an expression in a programming language that produces a
boolean value when evaluated, i.e., true or false
